Not only in Ireland.

Good to see archaeologists getting down to what is really important.

Billy Quinn and Declan Moore, two archaeologists with Moore Archaeological & Environmental Services (Moore Group) in Galway, believe that an extensive brewing tradition existed in Ireland as far back as 2500 BC. These ubiquitous monuments, which are visible in the landscape as small, horseshoe-shaped grass-covered mounds, have been conventionally thought of by archaeologists as ancient cooking spots, saunas or industrial
sites. However, Quinn and Moore believe that they may have also been used as breweries.
According to Quinn 'the tradition of brewing in Ireland has a long history, we think that the fulacht may have been used as a kitchen sink, for cooking, dying, many uses, but that a primary use was the brewing of ale.'

Seriously, i'm glad there are still people willing to do real science on the important things. i do, however, object to the brewing tradition of Erin being only 4500 years old! Surely a masterpiece such as Guinness needed more than 4.3 millennia to come to fruition.

Didn't somebody try this in Egypt?
