HAYB, which stands for How Are You Brewing, is a specialty coffee roastery in Warsaw run by a father and son team led by Wiktor Borowski, operating from Aleje Jerozolimskie with a customer focused approach that treats every interaction as an invitation to explore coffee together rather than a lecture from above. The roastery uses hand picked beans from small farms and roasts them at peak ripeness with an emphasis on seasonality and freshness, committing to extracting the maximum potential from every lot rather than applying a uniform house style. HAYB works with small importers such as 1000 Hills in Rwanda to maintain traceable supply chains, and the father and son dynamic brings a multigenerational perspective to a Polish specialty scene that skews young. The operation is socially conscious, producing special edition coffees for charitable causes including an International Women's Day release, and the How Are You Brewing motto extends beyond branding into a genuine philosophy of engagement that shapes how the team communicates with wholesale partners and home customers alike. HAYB has grown into one of Warsaw's most distinctive specialty roasters by combining family warmth, seasonal sourcing discipline, and a name that turns every bag of coffee into a conversation starter.
