About Kos Kaffe Roasting House
Kos Kaffe is a small-batch specialty coffee microroaster and cafe on Park Slope's 5th Avenue corridor, a husband-and-wife operation that roasts daily on an in-house 12kg Dietrich roaster, supplying both the cafe itself and a growing wholesale program. The seasonal single-origin lineup rotates with the harvests, and the espresso bar runs at a level that puts Kos Kaffe consistently in the conversation for best coffee in Park Slope. The space is generous for a Park Slope storefront, with both indoor seating and a back garden that becomes prime real estate in warmer months. The food program leans homemade and seasonal (breakfast plates, sandwiches, salads, pastries) and supports both quick visits and longer sit-and-stay sessions. One of the strongest specialty coffee programs in south Brooklyn.
