From the roaster

The Union No.4 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.
