Editor's Note
As of early 2026, London's speciality coffee scene is one of the most concentrated and competitive in the world. Within a few square miles, you can find roasters who have won World Barista Championships, roasters who train prisoners, roasters who have been pulling shots since before most of their customers were born, and roasters who opened last year with a 5kg Probat and a point to prove.
I have spent fifteen years in the coffee industry, including a decade working with Sanremo, one of the world's leading espresso machine manufacturers. In that time I have visited well over 60 UK roasteries, and a significant number of those are in London. This is not a list assembled from websites and press releases. I have stood in these roasteries, tasted from the hoppers, spoken to the people doing the roasting, and formed opinions the only way that matters - in the cup.
This guide covers 20 coffee roasters London has to offer, organised by area so you can plan visits or find someone local.

How We Chose These Roasters
Speciality coffee is coffee that scores 80 points or above on the Specialty Coffee Association's 100-point scale. It is graded by certified Q-graders who assess aroma, flavour, aftertaste, acidity, body, balance, uniformity, and cleanliness. This scoring system is the global standard for quality, and every roaster in this guide works with beans that meet or exceed this threshold.
Every roaster in this guide was assessed on five criteria, tested in March 2026 as part of our latest Editor Lab round. First, bean quality - are they sourcing and roasting speciality-grade coffee that performs consistently across multiple brews? Second, sourcing transparency - do they name farms, regions, altitudes, and processing methods, or do they hide behind vague descriptors? Third, roasting approach - is there a clear philosophy, whether light, dark, or somewhere deliberate in between? Fourth, visit-worthiness - can you actually go there, see the roaster, and buy a bag? Fifth, online availability - can you order their beans without a trip across London?
We weighted these criteria equally. A roaster with exceptional beans but no public-facing space still belongs here. A roaster with a beautiful cafe but average coffee does not. The Specialty Coffee Association scoring framework informed our quality baseline, but every assessment was grounded in direct tasting and visits rather than scores alone.
The 20 Best Coffee Roasters in London
East London (Hackney, Shoreditch, Walthamstow)
1. Square Mile Coffee Roasters
Location: Walthamstow, East London | Founded: 2008
There is a queue outside the Walthamstow roastery on Saturday mornings that tells you everything you need to know. Square Mile is where London's speciality coffee movement found its voice, co-founded by James Hoffmann and Anette Moldvaer - both World Barista Championship winners. The operation has grown significantly since 2008, but the roasting philosophy has not shifted: light, clean, transparent.
Their Red Brick blend is the signature espresso, a consistent, chocolatey shot that half the speciality cafes in London have served at one point or another. For filter, the seasonal single origins are where Square Mile shows its range. Ethiopian naturals with blueberry and tropical fruit. Washed Kenyans with blackcurrant acidity that cuts clean. Every bag carries full traceability - farm, altitude, variety, processing method.
The roastery itself is worth the trip to Walthamstow. You can watch the roasting, buy bags directly, and drink some of the best filter coffee in East London without a queue (midweek, at least). For readers looking for best organic coffee beans, Square Mile does not carry organic certification across its range, but its sourcing standards sit at the top tier of the London scene.
Editor's verdict: The benchmark. If you are new to London speciality coffee, start here and calibrate your palate against everything else.
2. Climpson & Sons
Location: Broadway Market, Hackney | Founded: 2002
Before most Londoners had heard the word 'speciality', Climpson and Sons were already pulling shots on Broadway Market from what was then a market stall. The name came from the old butcher's shop that occupied the site. The coffee came from Ian Burgess, who has spent two decades building one of East London's most respected roasting operations.
Their roastery sits under the railway arches near London Fields, and the cafe on Broadway Market remains one of Hackney's busiest weekend spots. The house espresso is a rotating seasonal blend - medium roast, balanced, designed to work with or without milk. The single origins rotate monthly and lean toward washed Central Americans and East Africans with clean, bright profiles.
What separates Climpson and Sons from newer East London roasters is institutional knowledge. They have been sourcing from the same farms for years, building direct trade relationships before that phrase became a marketing badge. The coffee is consistent, the sourcing is transparent, and the roastery is open to visitors who want to see the process first-hand.
Editor's verdict: Hackney's original. Two decades of roasting, and the quality has only gone up.
3. Balance Coffee
Location: London (online-first) | Founded: 2020
I founded Balance Coffee in 2020. It is a London-based roastery and appears in this guide alongside nineteen other roasters. I am including it here because it meets the criteria, not because I own it, and I want to be transparent about the relationship so you can weigh this section accordingly.
Balance Coffee was built because I could not find a coffee that met the same standard I applied to everything else I consumed - organic food, filtered water, ingredient labels I actually read. The range is certified organic by the Soil Association, and every batch is independently lab-tested for mycotoxins, mould, pesticides, and heavy metals. The lab results are published on the website. As of March 2026, Balance Coffee is one of very few UK roasters that publishes this data.
The range includes five blends and single origins across beans, ground, and Nespresso Original compatible pods. The Stability Blend is the signature - a Uganda and Mexico blend with chocolate, fig, and a clean finish. Balance Coffee is online-first, which means there is no roastery cafe to visit. That is an honest limitation in a guide that values visit-worthiness. For readers prioritising best healthy coffee beans uk and verifiable transparency, Balance Coffee occupies a niche that very few London roasters address.
Editor's verdict: Full disclosure - this is my brand. The lab testing and organic sourcing are genuine differentiators. The lack of a physical roastery visit is a genuine limitation.
4. Allpress Espresso
Location: Shoreditch | Founded: 1986 (New Zealand), 2010 (London)
Allpress started with a coffee cart in New Zealand in 1986. By the time they opened on Redchurch Street in Shoreditch in 2010, founder Michael Allpress had already built roasteries in Auckland, Melbourne, Sydney, and Tokyo. The London operation was not a new brand finding its feet. It was a mature roaster entering one of the world's most competitive coffee markets with decades of experience.
The Redchurch Street roastery and cafe is one of Shoreditch's quieter gems - a converted warehouse with the roaster visible from the cafe floor. Their house espresso blend sits in the medium spectrum, roasted for balance and milk compatibility rather than single origin fireworks. On the nose, dark chocolate and toasted grain. Through the body, smooth and rounded with a clean finish.
Allpress supplies hundreds of cafes across London and beyond. That wholesale scale has not diluted the quality. The consistency across extractions was one of the strongest we recorded, which reflects the kind of roasting precision that comes from doing this for nearly four decades.
Editor's verdict: A global operation that still roasts like a neighbourhood shop. The espresso blend is a masterclass in balance.
5. Dark Arts Coffee
Location: Homerton, Hackney | Founded: 2014
The branding hits you before the coffee does. Skulls, black packaging, tattoo-influenced design - Dark Arts Coffee does not look like a typical London speciality roaster. That is entirely the point. Founded by muralist Brad Morrison and friends in a Homerton railway arch, Dark Arts set out to make speciality coffee feel less precious and more accessible.
The coffee matches the energy. Their roasts sit darker than most London speciality roasters, with bold, full-bodied blends designed for people who want flavour they can feel. The espresso pulls thick and heavy - dark chocolate, molasses, a smoky finish that lingers. It is not subtle, and it is not trying to be. For filter, their lighter single origins show genuine range, with enough acidity and fruit character to satisfy the light-roast crowd.
Dark Arts has expanded from the original railway arch to multiple sites across Hackney and Shoreditch, plus a Soho flagship. Each location carries the same unapologetic aesthetic. If you find most speciality coffee shops a bit sterile, Dark Arts is the antidote.
Editor's verdict: Speciality coffee without the pretension. The roasts are bold, the spaces are loud, and the quality backs it up.
6. Ozone Coffee Roasters
Location: Shoreditch | Founded: 1998 (New Zealand), 2012 (London)
Walk into Ozone on Leonard Street and the scale of the operation is immediately clear. This is not a small cafe with a roaster tucked in the corner. It is a full restaurant, bar, and roastery occupying a former warehouse, with the Probat visible through glass panels from the dining floor. Ozone originated in New Zealand in 1998 and opened its London home in 2012.
The coffee programme is extensive. Their house blend is roasted for espresso extraction - medium body, caramel sweetness, a clean and approachable finish. The single origin filter menu rotates frequently and leans toward washed coffees from East Africa and Central America. What sets Ozone apart is the integration of food and coffee under one roof. The brunch menu is one of the best in Shoreditch, and the coffee matches it rather than playing second fiddle.
Online ordering is available, though the real experience is on-site. If you want to see a professional roasting operation running at scale while eating a properly cooked breakfast, Ozone is hard to beat in East London.
Editor's verdict: The full package - serious roasting, serious food, serious space. A destination, not just a coffee shop.
South London (Brixton, Peckham, Bermondsey)
7. Assembly Coffee
Location: Brixton | Founded: 2015
I have visited Assembly's Brixton roastery more times than I can reasonably justify on a review budget. The space on Ferndale Road is small, focused, and intensely coffee-obsessed. They roast with a precision that translates directly into what ends up in the cup, and their approach to sourcing is among the most rigorous in London.
Assembly's single origin offerings rotate seasonally and lean toward washed East Africans with bright, complex profiles. Expect bergamot, stone fruit, floral lifts - coffees that reward attention. Their espresso blends are built for speciality-forward extraction rather than safe, crowd-pleasing darkness. This is not a roaster for people who want background coffee. It is a roaster for people who want to taste what coffee can actually do.
The on-site cafe, Door, serves their range alongside a simple food menu. Online delivery is quick and well-packaged. For our detailed assessment, see our Assembly Coffee review.
Editor's verdict: Brixton's finest. Precision roasting, transparent sourcing, and single origins that compete with anyone in the city.
8. Volcano Coffee Works
Location: Brixton | Founded: 2010
Kurt Stewart started Volcano Coffee Works in Brixton in 2010, and the brand has grown steadily without losing its South London character. The roastery sits on Ferndale Road - the same street as Assembly - which makes this stretch of Brixton one of the most roaster-dense postcodes in the city.
Volcano's signature is The Brixton blend, a crowd-pleasing espresso with chocolate, hazelnut, and a smooth body that works exceptionally well with milk. It is the kind of coffee that converts people from supermarket beans to speciality without overwhelming them. Their single origins offer more complexity for those who want it, with rotating lots from Central and South America.
Beyond beans, Volcano has moved into the pod market with Nespresso Original compatible capsules and a subscription service. They are one of the few London roasters building a genuine multi-format business. For our full assessment, see our Volcano Coffee Works review.
Editor's verdict: Approachable speciality coffee with South London soul. The Brixton blend is a modern classic.
9. Old Spike Roasters
Location: Peckham | Founded: 2014
Old Spike is a social enterprise roastery that trains and employs people affected by homelessness. That mission is not a marketing angle bolted on to a coffee brand. It is the reason the roastery exists. Every bag sold funds the programme, and every hire is a step toward independent housing.
The coffee itself has improved steadily since the early days. Their house blend delivers a medium body with milk chocolate and nutty sweetness - straightforward, well-roasted, and consistent. The single origin range rotates and occasionally reaches the complexity of dedicated speciality roasters, though the focus here is more on reliable quality than experimental profiles.
The Peckham cafe is warm and welcoming, with a community atmosphere that reflects the brand's purpose. Online ordering is available for beans and subscriptions. If the social impact matters to you alongside the cup quality - and it should - Old Spike is one of the most genuine operations in London.
Editor's verdict: Coffee with genuine purpose. The quality has earned its place alongside the social mission.
10. The Gentlemen Baristas
Location: Multiple London sites | Founded: 2014
The Gentlemen Baristas had a turbulent period - entering administration in January 2024 before being acquired and relaunched later that year. The brand is back, operating multiple coffee houses across London with a roastery in Stratford. Whether the recovery holds remains to be seen, but the coffee quality under the new ownership has been solid in testing.
Founded by Henry Ayers and Edward Parkes, the brand built its identity around a Victorian gentleman's club aesthetic - warm interiors, attentive service, and a slower pace than most London coffee shops. The house espresso is medium roast, smooth, and designed for the long sit-down rather than the takeaway rush. Single origin options are available but not the main draw.
The Gentlemen Baristas occupies an interesting space between speciality and mainstream. The coffee is better than any chain, the experience is more considered than most independents, and the roastery in Stratford gives them direct control over quality. If they can maintain stability after the administration period, this is a brand worth watching.
Editor's verdict: A brand in recovery with genuine character. The coffee holds up, and the experience is unlike anything else in London.
Central and West London
11. Monmouth Coffee
Location: Borough Market and Covent Garden | Founded: 1978
If someone asks you what is the oldest coffee roaster in London, the answer is almost certainly Monmouth. Founded in 1978 by Nick Saunders and Anita Le Roy on Monmouth Street in Covent Garden, this is the roaster that introduced London to the idea that coffee could be traceable, seasonal, and worth thinking about. They were doing it before anyone called it 'speciality'.
The Borough Market stall, opened in 2001, is the one most people know - a permanent queue of tourists and locals clutching paper cups of filter coffee brewed from whatever is on rotation that week. The quality is consistently high. Monmouth sources directly from farms and cooperatives, roasts in-house, and prints full provenance on every bag.
What Monmouth does not do is sell online. You buy in person - Borough Market, Covent Garden, or Bermondsey. That deliberate limitation keeps the brand small and focused. The beans are among the best you can buy in London, and the experience of queuing at Borough Market on a Saturday morning has become a London ritual in itself. If you are a visitor exploring independent coffee roasters London has shaped over the decades, Monmouth is where the story begins.
Editor's verdict: The original London roaster. Nearly fifty years in, and still one of the best cups in the city.
12. Workshop Coffee
Location: Belgravia (new), formerly Clerkenwell and Fitzrovia | Founded: 2009
Workshop Coffee has had a complicated few years. The original Clerkenwell cafe that put them on the map closed in 2017. The Fitzrovia location followed in 2024. For a period, Workshop existed primarily as a wholesale roaster without a public-facing space. Then, in early 2026, they opened a new cafe and training academy in Belgravia - a short walk from Victoria Station.
The return is welcome. Workshop was one of the first London roasters to treat coffee sourcing with the same rigour that wine merchants apply to vineyards. Their approach is relentlessly quality-focused: small lots, seasonal rotations, detailed tasting notes on every bag. The roasting leans light-to-medium, emphasising origin character over roast character.
The new Belgravia space includes a training academy alongside the cafe, which signals their ambition to be more than just a coffee shop. Online ordering is available for their full bean range. If you tried Workshop years ago and lost track of them, the 2026 relaunch is worth revisiting.
Editor's verdict: A pioneer returns. The sourcing and roasting remain world-class, and the new Belgravia space gives them a home again.
13. Caravan Coffee Roasters
Location: King's Cross (and Exmouth Market) | Founded: 2010
Caravan occupies Granary Square in King's Cross - a converted grain warehouse that doubles as a restaurant and roastery. Founded by three New Zealanders in 2010, the brand started on Exmouth Market before expanding to what is now one of the most impressive coffee spaces in Central London.
The roasting happens on-site at King's Cross, visible from the restaurant floor. Caravan's approach sits in the medium range - roasted for flavour balance rather than light-roast acidity or dark-roast punch. Their blends are designed to work across brew methods, from espresso to filter to best coffee for moka pots. The food programme is substantial, making this a genuine all-day destination rather than a quick coffee stop.
Online ordering is available, and the beans are well-packaged with clear origin information. Caravan does not chase the same light-roast extremes as Square Mile or Assembly, but for readers who want a medium roast with complexity, this is one of the best options in Central London.
Editor's verdict: King's Cross at its best. Roastery, restaurant, and a medium roast that pleases everyone without boring anyone.
14. Grind
Location: Multiple (14+ London sites) | Founded: 2011
Grind started as a single coffee shop on a corner in Shoreditch in 2011. David Abrahamovitch turned his father's old mobile phone store into what has become one of London's most visible coffee brands, with 14 locations across the city, a nationwide grocery presence, and a growing online subscription business.
The scale could easily compromise quality. In Grind's case, it has not. Their house blend is a consistent, medium-bodied espresso with chocolate and caramel notes that works well as a flat white or a straight shot. The Nespresso-compatible pods are among the best-packaged in the UK, and their compostable pod line shows genuine commitment to sustainability beyond marketing.
Grind is a certified B Corp, which adds a layer of verified ethical accountability. The cafes are well-designed, the branding is sharp, and the online experience is polished. For our full assessment of the brand, see our Grind Coffee review. Whether Grind qualifies as 'speciality' depends on your definition. Whether it serves excellent coffee at scale is not in question.
Editor's verdict: London's most successful modern coffee brand. The quality holds across 14 sites, which is harder than it looks.
15. Kiss the Hippo
Location: Richmond (and multiple London sites) | Founded: 2018
Kiss the Hippo arrived in Richmond in 2018 and immediately set a new standard for speciality coffee in West London. The roastery is certified carbon-negative, the sourcing is direct trade, and the coffee is roasted on a Loring - a machine chosen specifically for its energy efficiency and roast consistency.
In the cup, Kiss the Hippo leans light. Their filter coffees are clean, bright, and origin-forward. The espresso blend has more body than the filters suggest, with stone fruit and milk chocolate coming through in a well-extracted shot. The Richmond roastery is the flagship, but additional sites in Fitzrovia and elsewhere have extended the brand's reach into Central London.
What distinguishes Kiss the Hippo from other young London roasters is the environmental commitment backed by measurable action rather than vague claims. Carbon-negative certification is verifiable, and they publish the data. For readers looking for specialty coffee roasters London can be proud of on sustainability grounds, this is the one. See our Kiss the Hippo review for a deeper assessment.
Editor's verdict: The sustainability leader. Carbon-negative roasting, direct trade sourcing, and coffee that backs up the mission.
North London and Further Out
16. Origin Coffee
Location: Shoreditch (London HQ), Cornwall (roastery) | Founded: 2004
Origin is a Cornwall roaster with a strong London presence. Founded by Tom Sobey in 2004, Origin was Cornwall's first speciality coffee roaster and has since grown into one of the most respected names in UK coffee. The roastery remains in Cornwall, but the Shoreditch site on Charlotte Road serves as the London headquarters and flagship cafe.
The coffee is sourced through Origin's direct trade programme, with the team travelling to producing countries to build relationships at farm level. In the cup, their roasts tend toward the lighter end - clean, nuanced, with origin character leading the profile. The espresso blends have enough body for milk-based drinks without losing the complexity that makes speciality coffee worth the premium.
The Shoreditch cafe is a thoughtfully designed space with a reputation for good food alongside the coffee. Online delivery is available nationwide. For our detailed breakdown, see our Origin Coffee review. If you want a roaster that bridges London's coffee culture with the quality sourcing more commonly associated with Nordic roasters, Origin is the closest London gets.
Editor's verdict: Cornwall roots, London presence, world-class sourcing. One of the UK's best, with a Shoreditch cafe to match.
17. Redemption Roasters
Location: Multiple London sites | Founded: 2015
I knew the Redemption founders before the brand was widely known. Their model is straightforward: train serving prisoners and ex-offenders as baristas and roasters through a genuine vocational programme, then employ them in the brand's coffee shops when they are released. The coffee funds the mission, and the mission shapes the business.
What surprised me was how much the coffee has improved since the early days. The espresso we tested in 2026 showed real progress - a Brazilian and Colombian blend with hazelnut, brown sugar, and a smooth chocolatey body. The finish is clean, medium-length, and slightly nutty. Consistency across multiple shots was strong. The roasting is done at HMP The Mount, which makes Redemption the world's first prison-based coffee roaster.
Redemption operates around ten coffee shops across London, including sites at King's Cross, Bloomsbury, and Victoria. Online ordering is available. For a deeper look, see our Redemption Roasters review. The social impact is genuine and verified. The coffee has caught up with the purpose.
Editor's verdict: Coffee that changes lives. The quality now matches the mission, and the London cafe network makes it easy to try.
Two More Worth Knowing
18. Terrone & Co
Location: Tottenham, North London | Founded: 2012
Terrone operates from a small unit on the Millmead industrial estate in Tottenham Hale, roasting on a 15kg Giesen. The name reflects the founders' dissatisfaction with traditional Italian coffee - 'terrone' is southern Italian slang, and the brand was built to challenge the assumption that Italian-style roasting means dark, bitter, and stale.
The coffee leans light-to-medium, with a focus on traceability and seasonal sourcing. Every bag carries full origin detail - farm, region, altitude, processing method. The range is small and curated rather than sprawling. In the cup, expect clean profiles with fruit and floral notes on the lighter offerings, and chocolate and nut on the blends.
Terrone does not have a public cafe, so this is an online order or wholesale discovery. The beans are well-regarded among London baristas who know the name, even if the brand lacks the visibility of its better-funded neighbours. For artisan coffee roasters London offers at the smaller end of the scale, Terrone is worth seeking out.
Editor's verdict: A quiet craftsman in North London. Small batches, full traceability, and a challenge to Italian roasting orthodoxy.e curious.
19. Carnival Coffee Roasters
Location: Penge, South East London | Founded: 2019
Penge is not where most people would expect to find a speciality roaster, and that is part of the appeal. Carnival Coffee Roasters was born out of a trip to Chiapas, Mexico, where founders Juan and Jayne experienced coffee that changed their perspective entirely. They came back, left their jobs, and opened a roastery and cafe on Penge High Street.
The roasting is done on-site in a compact space that doubles as the cafe. The range is small, the batches are tiny, and the community around the shop is fiercely loyal. In the cup, expect medium roasts with clean sweetness and approachable complexity - coffees that work for newcomers to speciality without patronising experienced drinkers.
Carnival is the kind of roaster that makes London's coffee scene so deep. It is not in Shoreditch, it is not on Instagram with a million followers, and it is not backed by venture capital. It is two people who care about coffee, roasting it well in a South East London suburb, and building something real from the ground up.
Editor's verdict: A neighbourhood gem in an unexpected postcode. Small, personal, and exactly the kind of roaster that makes London special.
20. Perky Blenders
Location: Walthamstow, East London | Founded: 2015
Perky Blenders started on a Piaggio Ape - a three-wheeled Italian van - serving coffee at Walthamstow market. The husband-and-wife team behind it had no investor backing and no industry connections. They learned to roast, built a following one cup at a time, and now operate four shops across East London with around fifty wholesale accounts.
The roasting style is approachable without being bland. Jazzy Max, their house blend, is a crowd-pleaser built for milk-based drinks with a smooth, chocolatey base. Anthem Blend leans fruitier and works well as filter. The Variety Club and Acacia Blend round out a range that stays tight and focused rather than trying to cover every origin on the map. Pricing sits around GBP 10.50 per 250g bag, which is competitive for London speciality.
Perky Blenders won a Time Out award and has built a loyal local following in Walthamstow, an area that has seen rapid change over the last decade. The brand has grown without losing its neighbourhood feel. For local coffee roasters London offers in the east, Perky Blenders is a genuinely community-rooted operation that happens to produce solid coffee.
Editor's verdict: From a three-wheeled van to four shops. Walthamstow's own roaster, built on approachable coffee and stubborn independence.
London vs UK - Why London Roasters Are Different
London's speciality coffee roasters London scene differs from the rest of the UK in three ways. First, density. Within the M25, you can visit more roasteries in a single day than in any other British city. That competition forces quality upward. Second, diversity. London attracts roasters from New Zealand, Australia, Scandinavia, and across Europe, which means the city's coffee culture is not a single style - it is a collision of traditions. Third, access. London roasters have wholesale accounts with hundreds of cafes, which creates the volume to justify experimental lots and limited releases that smaller-city roasters cannot sustain.
That said, some of the best coffee roasters uk produces are outside London. Cornwall has Origin. Bristol has Extract and Clifton. Edinburgh has Williams and Johnson. The quality is national, but the concentration is uniquely London.
What to Avoid When Choosing a London Roaster
As of early 2026, London has hundreds of coffee shops and dozens of brands that call themselves roasters. Not all of them deserve the label. Here are the red flags that separate genuine speciality roasters from the rest.
Chain coffee posing as speciality. Several high-street chains have adopted speciality language - "single origin," "artisan roasted," "hand-crafted" - without the sourcing or roasting to back it up. If the brand operates more than 20 locations and cannot tell you the farm name on its house blend, it is not a speciality roaster. It is a coffee chain with better marketing.
Tourist-trap cafes near landmarks. Coffee shops clustered around major tourist areas (Tower Bridge, Covent Garden, Oxford Street) often charge speciality prices for commodity-grade coffee. The test is simple: can they tell you where the beans came from, who roasted them, and when? If the barista does not know, move on.
Instagram-first roasters with no sourcing transparency. A beautifully designed bag and a strong social media presence do not guarantee quality. If a brand cannot name the farms, regions, altitudes, and processing methods for the coffee it sells, the packaging is doing more work than the roaster. Every brand in this guide discloses full origin information. That should be the minimum standard.
Frequently Asked Questions
Who Is the Best Coffee Roaster in London?
There is no single best roaster. Square Mile Coffee Roasters sets the benchmark for light roast speciality with full traceability and World Barista Championship pedigree. Monmouth Coffee offers the deepest heritage, having roasted in London since 1978. Assembly Coffee delivers the most exciting single origins. The best roaster for you depends on whether you prioritise roast style, sourcing transparency, visit experience, or online convenience.
Where Can I Buy Speciality Coffee in London?
Every roaster in this guide sells directly - either from their cafe, roastery, or online shop. For in-person browsing, Borough Market (Monmouth), Broadway Market (Climpson and Sons), and Shoreditch (Allpress, Origin, Dark Arts) offer the highest concentration of options. The London Coffee Festival, held annually, is the single best opportunity to taste from dozens of roasters in one visit.
What Is the Oldest Coffee Roaster in London?
Monmouth Coffee Company, founded in 1978 on Monmouth Street in Covent Garden, is widely recognised as London's oldest speciality coffee roaster. They predated the modern speciality movement by decades and remain one of the best roasters in the city nearly fifty years later.
Can I Visit Coffee Roasteries in London?
Yes. Most roasters on this list have public-facing cafes where you can taste their coffee and, in many cases, watch the roasting in progress. Square Mile (Walthamstow), Ozone (Shoreditch), Caravan (King's Cross), and Allpress (Shoreditch) all roast on-site with the equipment visible. Monmouth sells directly from Borough Market and Covent Garden. Exceptions include Balance Coffee and Terrone, which are online-first or wholesale-focused without dedicated visitor spaces.
