Vila Boa

Vila Boa is an espresso for anyone who likes their coffee bold and well-balanced. The beans come from Fazenda Vila Boa in Sul de Minas, Brazil—processed using the natural method and sun-dried. We dark-roast Vila Boa in the drum roaster. This brings out notes of walnut, cocoa, and raisins, rounded out by dried fruit. Low acidity, full body, a dense crema—a straightforward espresso with depth, enjoyed black or with milk. There’s more to Vila Boa than just the flavor. The beans make their way to us under sail: low-carbon sea transport instead of container shipping. The coffee is grown as part of Cafés de Forêt, an initiative by our importer Belco to protect forests: The coffee plants are cultivated using agroforestry practices, growing among trees rather than on cleared land. Vila Boa is also part of the Women Coffee initiative. Women do a large portion of the work in coffee farming but rarely own land or hold positions of responsibility. The initiative strengthens their role in production—and entire families benefit as a result: through better education for children, improved health, and economic stability.

Wachile Garse

From the legendary Yirgacheffe region, grown at an elevation of over 2,060 meters in the Gedeo District—one of the world’s most renowned coffee-growing regions. This natural-process coffee is the result of the work of 110 coffee farmers who have passed down their knowledge of coffee cultivation from generation to generation. After harvest, the coffee cherries dry for three weeks on elevated drying beds to ensure even, gentle drying. Here’s what you can expect in your cup: delicate notes of chamomile and almond meet the juicy fruitiness of strawberry and apricot, rounded out by a subtle hint of coconut.

Mirim

Our Mirim isn’t for those in a hurry. It starts with the shipping: The beans travel to us from Brazil on a sailing freighter, propelled mainly by the wind. We roast it dark and patiently in the drum roaster. The result is an espresso without any frills: bold, with low acidity, but full of notes of dark chocolate and roasted cashews. A hint of brown sugar and dried fruit gives it the necessary depth, while the dense, velvety crema reveals what it’s made of. Whether you drink it straight as an espresso or in a cappuccino—you’ll taste the time that’s gone into it.
