What Makes the Best Coffee Roaster?
There are a few factors that make a really great coffee roaster.
Quality of the roasted beans.
Firstly and the most obvious is the quality of the roasted coffee. Coffee roasting is an art as well as a science.
Raw coffee beans are placed into a coffee roaster (essentially a revolving oven) and roasted for specific amount of time.
It is up to the coffee roaster to best highlight the inherent flavour compounds of the coffee by manipulating variables such as temperature or the roaster, drum speed, airflow and roast time.
The roast profile of the coffee is forever being tweaked by really good roasters as outside factors such as humidity can also some into play.
Quality of green beans.
Green coffee, also known as raw coffee, are what coffee roasters purchase either directly from coffee farms or via coffee importers.
The green coffee beans would have initially been harvested as coffee cherries before being processed and dried at origin.
The green coffee is then roasted into what we refer to as coffee beans.
The green coffee that the coffee roaster uses is an extremely important factor in how we decided on the best coffee roasters in the UK.
Firstly, like any other product, there is a whole scale of quality. In green coffee, the quality scale starts at the lowest grade of commodity coffee that there is, which usually is later processed into instant coffee all the way through to specialty grade coffee which can be sold at auction for thousands per kg at auction.
The way green coffee is graded depends on a number of factors where high quality greens usually come from farms at higher altitudes, that grow specific varietals of coffee and conform to high standards of coffee farming.
Ethics.
The best coffee roasters in the world today not only produce the best coffee but also lead the way in their values and ethics.
This includes sustainable practices throughout their business, from paying the farmers a wage that the deserve and trying to source coffee directly from the farm all the way through to the coffee roaster and packaging that they use.

Origin Coffee Roasters
Origin coffee was founded over 15 years ago by Tom Sobey and roast their coffee in Cornwall.
Having worked closely with his fathers coffee business growing up, he has always been involved in the industry.
After a trip to Australia in the early 2000’s where coffee culture reigns, Origin was born.
Since then Origin coffee has evolved into a full team of industry professionals, a world class coffee program, 6 coffee shops and an ever evolving product range.
They are one of the founding fathers of third wave speciality coffee in the UK and are amongst the front runners in the industry.
Origin coffee source direct from the farms. A practice that is true to speciality coffee and one that rewards the people who grow the coffee rather than the many middlemen.
Through their direct trade practice they’re able to support their farm and mill partners directly, giving their customers full traceability of the coffee in their cup.
They attempt to visit the farms at origin every year in El Salvador, Nicaragua, Colombia, Brazil.
The relationships that they have built over the years of visiting these coffee growing regions means they are able to ask questions and provide support to workers and their families.
What sets certain coffee roasters apart for me is the stories that they tell through coffee.
Origin coffee does exactly that, the quality of their coffee is matched by the stories behind it and it’s easy to see why these guys are paving the way into the 4th wave.

Foundation coffee roasters are an independent roastery and equipment supplier based in St Ives, Cornwall.
They began their coffee journey with a mission to create quality and high-grade speciality coffee while at the same time using the best possible ethical practices that have a minimal impact on the environment.

3. Assembly Coffee Roasters
Assembly are the quality and customer focused UK coffee roaster based in Brixton, London.
They are one of the few coffee roasters in the UK that are pushing the boundaries of each aspect of their business.
The Assembly roastery is housed in a 19th century fire station in the heart of London.
The Loring roaster alongside a state of the art coffee sensory lab and a couple of event spaces to hold cuppings is a testament to how serious these guys take specialty coffee.
Launched in 2015 during the annual London coffee festival, Assembly are now showcasing their coffee on a global scale.
There is no compromise in quality and the meticulous quality control that these guys have as a standard is why they are dropping some of the best speciality coffees on the market today.
The biggest difference in how Assembly operates for me is their collaborations.
When talking to their business manager, Ed, he explained how the team is in constant conversation with their customers, whether it’s a retail customer purchasing a 250g bag every other week or a wholesale cafe that orders dozens of kilos per week.

4. Rounton Coffee Roasters
Rounton Coffee Roasters are based in North Yorkshire.
Their mission is simple. They aim to source coffees that guarantee a fair cut for everyone at origin, and they make sure that their hard work comes through in the taste of the coffees that they roast.
Their story began 8 years ago in Sumatra, where they met a wonderful group of farmers in a region that they continue to support today.
It was this meeting that brought to their attention the plight of many smallholder farmers around the world. They decided that if they could do something for them, they should, and so on their return to the UK, Rounton Coffee Roasters was born.
Rounton finds themselves today, having formed relationships not just in Sumatra, but all over the world.
They believe that quality and sustainability can (indeed, must), go hand in hand.

Their ethics transcend all the way from Colombia where they support sustainable coffee projects all the way to South East London where they offer local delivery on a bicycle.
Their story started in Medellin, Colombia where they grow and produce coffee on their family farm.
The farm has been in the family for generations ever since Juan’s Grandfather won a mountainside on the outskirts of the city in a very lucky game of cards. Even more luckily the conditions were ideal for growing coffee.
Fast forward to today and Juan's Parents, Aunties and Uncles still live and work on the mountainside.
The coffee farm is surrounded by orange groves and banana plants with a waterfall separating the boundaries with neighbouring farms. Traditional drying methods are still used.

Mission Coffee Works started as a street van back in 2012 serving coffee to the people of Peckham, London.
Shortly after they relocated both their physical location and focus and started roasting coffee.
The green beans that Mission purchase are of the highest quality, while at the same time adhering to their ethics and values of sustainability.
They don’t hide from the fact that the coffee has already been on such a long journey to get to their coffee roaster and are humble in their marketing approach.
They make sure their customers are fully aware that the farmers, pickers, mill workers, green buyers and importers all made their cup of coffee possible.
Their passion for coffee enables them to build awareness of the complicated supply chain in speciality coffee and has given them the platform to build sustainable relationships from the finca to the flame.
At Mission they have a mission - to source incredible green coffee and roast it with care. Hoping that you have as much fun brewing it as they did getting it to you.
A few steps that they have taken to stay on top of the sustainability game is making a huge effort to recycle everything they can in the roastery.
It is sometimes painful to see the amount of waste in shipping and packaging, however with a little innovation reusing or recycling certain things can really help.

Why Choose Independent Coffee Roasters?
The term ‘independent coffee roaster’ has, over the last few years, become a sort of stamp of quality when it comes to coffee and although there are exceptions generally speaking you will find higher quality coffee at independent coffee roasters.
Commercial coffee roasters (brands that can be found in the supermarket) don’t really have the scope to source such high quality raw coffee.
This is because these brands produce huge amounts of roasted coffee that has to be consistent, high quality specialty coffee is generally grown on small farms that produce smaller lots of coffee, so it is hard for a commercial roaster to produce truly single origin coffee, traceable back to a particular farm.
Secondly, the coffee roasters that commercial grade coffee is roasted in are huge machines capable of producing hundreds of kilos of coffee per hour, this is great for quantity but less so for quality.
Independent coffee roasters are able to purchase a relatively small amount of coffee and roast in coffee roasters that hold from 0.5kg up to 30kg.
This gives the coffee roaster much more control during the roast so they are able to manipulate the profile as they wish.
Another aspect that sets independent coffee roasters apart from commercial grade, is that most independents will pay well above the fair trade coffee price for green coffee beans and will support the sustainability of coffee farming as well as other parts of the supply chain.
To surmise, you are not only on the whole, purchasing a better raw product when you buy through independent coffee roasters but also a better quality of roast as well as a more sustainable supply chain.
How Many Coffee Roasters Are There in The UK?
There are currently over 600 coffee roasters in the UK. This number does change as the coffee industry ebbs and flows.
