There has been an abundance of full moon theories correlating it with lunar effects and superstitions since time immemorial. But, a Belgium based brewery has debunked the full moon theory to turn it in favor of its own by producing its first batch of specialist beer “Paix-Dieu” brewed by the light of a full autumnal moon. Brewery Caulier, a family-owned brewery in Peruwelz, a small, sleepy town in southern Belgium, has found out that the full moon speeds up the fermentation process, shortening it to five days from seven, which adds extra punch to the beer without making it harsh.
"We made several tests and noticed that the fermentation was more vigorous, more active," explained Roger Caulier, the third-generation owner of Brewery Caulier, which began in the 1930s. The end product is a finely balanced, gold-colored beer which has 10 percent alcohol by volume and is stronger, with a long lasting flavor. Brewery Caulier, which uses methods dating from the 1840s and is well-known for its artisanal beers, plans to produce about 12,000 bottles of its full moon beer, called Paix-Dieu (Peace-God), which go on sale on October 31. Caulier is in talks to distribute his unique beer in the U.S. and Japan as well.
