But because the ice forms around yeast cells, protein particles, etc., these are removed as well; leaving less taste and character. What is cold-filtering? This is a way of clarifying beer in a shorter time. Beer becomes clearer as proteins and other particles coagulate and settle. The beer can then be drawn off and bottled. One way to reduce the settling time is to chill the beer so t
