I finally broke down and sent a couple of my wines from 2019, the last year I had any grapes, to a lab in Napa. Just got the results back but I'm kind of lost as to how to interpret them and I'm hoping there's a chart somewhere they can tell me what these values should be and how to correct it and I don't have to search through all my books. Please see attached report.

Your VAs of 0.4 and 0.5 g/100 mL are way high (numbers above 0.15 are usually noticeable and not allowed per CFR). Gusmer reporting malic at <0.3 g/L is not running a sensitive-enough test. You really want to see malic below 0.05, and at least below 0.1, to be sure MLF doesn't spontaneously start up in the bottle. [email protected]
