Castle Brewery is an independent craft brewery based on the banks of the River Fowey in the historic Cornish market town of Lostwithiel. Established in 2007, the brewery has built a strong reputation for producing a diverse range of high-quality cask ales inspired by both British pub traditions and modern European styles.

In November 2026, the Harwood family took ownership, bringing a renewed focus on a carefully curated core range of classic cask ales, alongside a selection of exciting keg beers.

Artisan at heart, Castle Brewery handcrafts unfined, unfiltered, and vegan-friendly beers, combining traditional brewing methods with contemporary creativity. Each brew reflects a commitment to quality, character, and the unique landscape of Cornwall.

Whether you're seeking timeless British classics or fresh, modern flavours, Castle Brewery offers a distinctive and authentic craft beer experience.
