"Our winery performs static clarifications without using egg albumin, casein (protein derived from milk), gelatin (which is obtained from animal cartilage, almost always from fish) or the socalled ichthychola (which is obtained from the swim bladder of some fish), using only tangential filtering for all varietals."
