Celebrating 30 Years of Heavy Seas
This announcement comes at a milestone moment. Heavy Seas—Maryland’s largest craft brewery—celebrates its 30th Anniversary on December 8, 2025. To mark the occasion, Heavy Seas will host a 30th Anniversary Celebration at the brewery on Saturday, December 6, 2025, in partnership with the Brewers Association of Maryland (BAM). A portion of proceeds will benefit BAM’s mission to support and promote Maryland’s craft beer industry. Details for the Anniversary event will be announced in mid-October on the Heavy Seas website and social media channels.

The event will also feature the release of 30 Year Storm, a limited barrel-aged strong ale (11.5% ABV), aged in bourbon, rye, and sherry barrels. “This anniversary beer represents the culmination of three decades of creativity, experimentation, and resilience—everything Heavy Seas stands for,” said Caroline Sisson.
