We buy our coffee from Allpress, their Redchurch blend specifically. If you haven't heard of them, they are simply great.
Here's a bit of background info on how they go about sourcing and roasting their speciality coffee:
"Finding top-quality Arabica beans involves an on-going search, so we invest a lot of time looking for small farms, estates and co-ops that are sustainably managed with high standards of agricultural practice and specialise in high grade beans. We form direct relationships with these growers so our supply arrangements are made with people managing the farms.
To secure the continual quality and quantity we require and see how excellent coffee is brought to market we visit farmers, millers and exporters in the various coffee growing regions. At origin, there is always something new to learn about different farming methods, customs and the conditions influencing the production and sale of coffee.
During these trips we meet and often stay with the growers, see where their beans are grown, talk to the pickers and processers and spend time tasting the unique annual crops for flavour, body and aroma. Sharing conversation over a cupping, a meal or a walk around the coffee farm brings a friendly familiarity to these visits. Being amongst the communities also gives a firsthand look at how they are benefitting from above market prices they receive for their coffees.
This way of buying coffee is mutually rewarding and achieves our continual focus on selecting beans for outstanding flavour in the cup."
