The use of cation exchange resins in wines: Effects on pH, tartrate stability, and metal content
Abstract Treating wines with cation exchange resins allows the reduction of pH and contributes to limiting the formation of tartrate salts by exchanging cations such as potassium with hydrogen ions. This manuscript summarizes the results of a series of laboratory and winery-scale trials performed wi...
