text_A: Some brewers add one or more clarifying agents or finings to beer, which typically precipitate (collect as a solid) out of the beer along with protein solids and are found only in trace amounts in the finished product. This process does not make the beer appear bright and clean but rather it has the cloudy appearance of ethnic and older styles of beer such as wheat beers. Examples of clarifying agents include isinglass, obtained from swimbladders of fish; Irish moss, a seaweed; kappa carrageenan, from the seaweed "Kappaphycus cottonii"; Polyclar (artificial); and gelatin. If a beer is marked "suitable for vegans", it was clarified either with seaweed or with artificial agents.
text_B: Does the public like clear or cloudy beer better?
DON'T KNOW.
