Amersfoorts Hoppen 1475 is Rock City's tribute to the medieval brewing traditions of Amersfoort. This 8.5% ABV Old Ale was developed in collaboration with Brouwerij Brouwersnös as a reconstruction of the first beer style Amersfoort ever produced. From a single base recipe of 2000 litres, five distinct fruity variants emerged, each with its own character.

The name references 1475, a year from Amersfoort's brewing heritage. Rock City brings this legacy into the present by combining artisanal methods with creative brewing. A beer that bridges history and craftsmanship.
