Kasztelan beer

Kasztelan is a popular Polish beer brand with deep roots in the Sierpc region of Poland. The brand originated at the Browar Sierpc brewery, which began its brewing heritage in the early 20th century. Known for its traditional recipes, Kasztelan has become a staple of the Polish beer market, particularly recognized for its unpasteurized version.

The brand is currently owned by Carlsberg Polska, a subsidiary of the Danish multinational brewing giant Carlsberg Group. While it maintains its local identity and continues to be produced primarily in Poland within the Carlsberg network of breweries, its ultimate oversight and strategic direction come from Denmark. The brand represents a blend of historic Polish brewing tradition and modern international distribution capabilities.
