At least as early as the 6th century, the Druidic legendary person Ceridwen is associated with cauldrons and intoxicating preparations of grain in herbs in many poems of Taliesin, particularly the Hanes Taliesin. This preparation, Gwîn a Bragawd, is said to have brought "science, inspiration and immortality".
In the Laws of Hywel Dda, meanwhile, a distinction is drawn between bragawd and cwrwf, with bragawd being worth twice as much. Bragawd in this context is a fermented drink based on cwrwf to which honey, sweet wort, and ginger have been added.
Welsh beer is noted as a distinct style as late as 1854, with a recipe made solely from pale malt and hops described in a recipe book of the time.
Wales, along with the rest of Britain, came under the influence of the temperance movement, along with a burgeoning Welsh moral code based on presbyterian and other non-conformist beliefs in relation to alcohol. This rested against a background of places where there has historically been a lot of heavy industry such as coal mining in south Wales and the north east. This has given some people[who?] the impression that all Welsh beers have been very weak. However, as with beers all over Britain, alcohol percentages vary.
Wrexham was one of the first places in the UK to brew lager. Homesick German immigrant brothers from Saxony started the process in 1882. Its demise came in 2000, when the site of Wrexham Lager was sold and subsequently demolished. Investment by the Welsh Development Agency has helped establish a large number of breweries in Wales in recent years.
Felinfoel Brewery was the first brewery outside the US to sell beer in cans.
