Diamonds Roastery is a family operation run by Tomáš and Dáša from Dunajská Lužná, a town just outside Bratislava, that traces its origins to a Christmas gift in 2014: a plastic popcorn maker and one kilogram of green Kenyan coffee. That modest start led to a Huky 500g roaster in 2015, a four day roasting course with Cup of Excellence judge Paul Songer in Kyiv, and eventually a full specialty roastery that now tastes over 800 coffees a year to select roughly 50 exceptional lots. The company has expanded beyond coffee into bean to bar chocolate production, and its packaging is known for playful Slovak phrases contributed by both the team and their customers. Diamonds supplies a network of cafes across Slovakia and Czechia and sells direct through its online shop.
