Kronenbourg 1664 admin | 08/11/2015 Kronenbourg 1664 was named after the year the Hatt family, the founders of Kronenbourg, first started commercial brewing. Kronenbourg is the fifth oldest beer brand in the world that still exists today. Its golden hues and delicate bitterness come from selecting the best hops, the ‘Strisselspalt’, and the unique know-how of Kronenbourg’s master brewers for over 300 years. Strisselspalt is also named the caviar of hops by the expert master brewers around the world for its low bitterness and aromatic qualities. Its specific soil and culture technique requirements makes it rare and quite unique to the Alsace Region and Kronenbourg recipes.
