Bluestone Brewing Company is a family-run microbrewery situated in rural North Pembrokeshire, Wales, operating from a 300-year-old dairy constructed with locally sourced Bluestone from the Preseli Mountains. The brewery crafts a diverse range of handcrafted, vegan-friendly beers, utilizing pure spring water from their land, which requires no additional filtering or chemicals. Committed to environmental sustainability, Bluestone Brewing employs solar panels, a reed bed drainage system, and repurposes brewing by-products for farm animals. In 2018, they became the first brewery globally to receive the Green Key Accreditation, and in 2023, they were honored as Sustainable Business of the Year at the SIBA Business Awards. Visitors can enjoy their taproom and events venue on-site, as well as two craft beer and pizza restaurants, Grain, located in St Davids and Carmarthen. ​
