Metatartaric Acid In Wine Kit
Rich Weaver — Casper, Wyoming asks,
I am making one of the ultra premium wine kits, an Australian Shiraz. The instructions say to add the metatartaric acid package after racking on day 42 or 56. What is the purpose of adding the metatartaric acid on day 42 or 56 rather than adding it right after the Kieselsol and Chitosan addition on day 28 (approximately)?
