Rwamatamu Espresso

Calendar Coffee is a seasonal roaster based in the west of Ireland with sustainability baked right into the business. They roast single-origin espressos and filters from Latin America and Africa — think Peru, Rwanda and Colombia — rotating with the seasons, and they take the ethics seriously enough to publish annual impact reports on their pricing, footprint and finances. The goal, in their words: lower their impact, keep producers profitable, and champion the world's best coffee. Sold online across Ireland with wholesale and a subscription. A lovely, conscientious pick if you want clean, seasonal single origin specialty coffee from the Emerald Isle.
