Low pH, testing for TA in cider and fining with bentonite:Testing Times

摘要

At our laboratories we service a wide array of winemaking clients, from large wine companies through to backyard hobbyists. We also see a wide variety of wines, from finished products through to works very much 'in progress'.Recently we encountered a red wine with an unusually low pH from a very small producer. With some knowledge of what was typical of the variety, region and vintage from which the grapes had been sourced, a discussion was initiated with the client to determine the reasons behind, and impacts of, such an unexpectedly low result.
