Situated on a working farm in the Preseli Hills of North Pembrokeshire. The water use for Bluestone Brewery's products filters down off the Preseli Mountains, through the organically farmed land at Tyriet, and collects in a well at the foot of the hills. As beer is 98% water, the Bluestone water gives the beer a purity unique to this traditional brewing area of North Pembrokeshire, and after all there is always plenty of water falling from the sky over West Wales.
