Awesome words spoken by Jean Van Roy of Cantillon that every brewer of sour beers should know.
What happens when a beer gets sick? To quote Dr. Evil “It got weird didn’t it?” That is what happens when a beer goes sick…. It gets weird. The awesome sour beer you last tasted is suddenly ropey, buttery, slick, and oily. It can happen in the fermenter, the bottle, or it can happen during both. Yes the beer can get sick twice.
What can cause the sickness? Pediococcus can give off the buttery/diacetyl/ropiness. Technically a Polysaccharide will form as a layer in the beer.
