Suds or suds?

Archaeologists have long known that Vikings loved their ale, but, according to Merryn and Graham Dineley, the experts have seldom considered just where the ale was brewed. Now, a new study speculates that stone structures in Britain, once believed to be bathhouses, might actually have been brewhouses.

The Dineleys, both experts in medieval brewing, have studied "a stone-built installation at Cubbie Roo's Castle, on the island of Wyre, Orkney — a Viking stronghold of the 12th century AD." According to the article in i09:

The Dineleys theorize that the structure would have made for an excellent mash oven, with the cauldron sitting above the fire. And in fact, they say it's the best example of a Viking brew house in Britain. The room is well equipped with substantial drains, it has a stone shelf for the storage vats, and a drain beneath.
