Feisty Beer Co. is a modern nano-brewery in the historic brewing town of Wooburn Green. Established in 2020, with a view to reintroduce the Williams family's brewing history within the parish of Wooburn, Buckinghamshire. The Royal Stag Brewery (Williams of Wooburn Ales) was established seven generations ago in 1833 by Thos. Williams and run by the family for four generations until the outbreak of WWI broke the family connection, and the brewery was eventually sold to another local brewery (Wethered & Sons Ltd) in 1927.
