Has Sam Calagione heard about this?

A Japanese brewery makes a beer using milk and calls it Bilk.

Does this qualify as an extreme beer? Dogfish Head Brewery founder Sam Calagione provides this definition in Extreme Brewing: “Extreme beers are brewed with more amounts of the traditional ingredients or non-traditional ingredients.”

Although several American microbreweries have brought back the almost extinct British-style milk stout we’re pretty sure most would consider milk a non-traditional ingredient.
