Help interpreting wine analysis report

[Shortandfuzzy]

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.

Here's my very quick interpretation, from memory. Ph is fine, but the Free SO2 numbers looked to be low. The baco to be protected (by SO2 and k sorbate from refermentation). Other than that numbers looked just fine.

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]
