Wines are fermented fruit beverages, usually 9% to 15% alcohol by volume, with a pH of about 3 to 4 from tartaric and malic acids and added sulfites as preservatives. Wineries use tanks for fermentation, settling, blending, aging and bottling preparation. Wine storage requires food-grade materials that impart no taste or odor, plus tight lids to limit oxygen exposure. Use the compatibility ratings to choose the right tank resin, fittings and gaskets.
