RT Journal Article SR Electronic T1 The Effect of Refrigeration, Bentonite Clarification and Ion Exchange on Potassium Behavior in Wines JF American Journal of Enology and Viticulture JO Am J Enol Vitic. FD American Society for Enology and Viticulture SP 208 OP 212 DO 10.5344/ajev.1968.19.4.208 VO 19 IS 4 A1 H. W. Berg A1 Raul T. De SOTO A1 M. Akiyoshi YR 1968 UL http://www.ajevonline.org/content/19/4/208.abstract AB Though the response of wines to refrigeration varies greatly not only between types but even between wines of the same type, it was found that the decrease in KHT (potassium bitartrate) content between 4 and 6 days of refrigeration may be used as a guide to determine the feasibility of continued refrigeration. Both bentonite fining and ion exchange materially decrease the amount of KHT which wines, are capable of holding in solution, with ion exchange having the major effect. The two effects are not strictly additive. The effect of bentonite fining varies with the manner in which it is done. The variation is apparently clue to the differential adsorption of certain compounds by the bentonite.
