The Union No4 Subscription
The Union is a clean, medium-bodied and perfectly balanced coffee with a subtle sweetness that embodies all we love about specialty filter coffee.
The Union No4 has been Built on the same concept as our existing coffee blends, but this time specifically developed for filter brew methods. This is our first blend designed for filter brewing, created over many months of cupping and fine tuning at our Ammanford roastery, and we are proud to give this blend our no4 status.
This Filter Blend is clean, medium-bodied and perfectly balanced with a subtle sweetness that embodies all we love about specialty filter coffee.
Uganda, Mount Elgon, Gibuzale
The slopes of Mt. Elgon in the East (bordering Kenya) are ideally suited for the production of high-quality specialty coffee.
The locals believe that God lives on Mt. Elgon – far beyond where people venture – and that when He is happy, he delivers rain to the bountiful gardens clinging to the mountainside. Indeed, these green, fertile hillsides are nearly divine territory for the production of spectacular coffees, and producers are increasingly realising their potential.

Grind Information
Please note, our espresso grind is suitable for most home coffee machines. If you have a commercial grade coffee machine, E.g. Linea Mini, then please add an order note in your basket, requesting commercial espresso grind.
We would always recommend that you use a grinder at home in order to achieve the grind suitable for your particular brewing equipment, but we appreciate that this is not always possible, so we do offer our coffee as ground. We offer grind options that we think would achieve the best results from the numerous variations of machines and equipment that are available to consumers, but we cannot guarantee that our ground options will work with every unique set up.
