They focused on malic acid, which is found in apples; lactic acid, which can be found in fermented foods; choline chloride, which is a salt often used as a food additive; and glycerol, which is often used as a sugar substitute.

But they have even more salt and more unidentifiable ingredients like Dextrose, Malic Acid, Red 40, Blue 1, Yellow 5, Disodium Inosinate and Disodium Guanylate.

Several laboratory studies have also shown that the combined effects of wine alcohol and organic acids, such as malic acid, can prevent the growth of E coli and Salmonella.

The chardonnay was made idiosyncratically, without malolactic fermentation, a process in which tart malic acid is converted by bacteria into softer lactic acid.

Some are taking a page from White Lyan, a now-closed but pioneering cocktail bar that had a limeless daiquiri, made with a science kit combination of powdered citric acid, malic acid, tartaric acid and phosphoric acid, mixed with water and salt.
