No Malic Acid

[Jonathan Silberlicht]

I should be happy about it, but 2 days after inoculating my Cab Sauv with VP41 I do not see any more malic Acid in the chromatography test. Is it really possible that the acids are converted so fast? The yellow dots are quite clearly in the lactic and Tartaric acid camp and nothing visible for malic.

While punching down the grapes I was using the same punch down tool between multiple fermenters, 2 of which were already undergoing MLF. Is it possible I inadvertently inoculated the Cab Sauv early in AF due to pulling some ML bacteria from one fermenter to another? All wine was from fresh grapes btw.

Thanks,

You almost certainly cross inoculated everywhere. Being done in two days is certainly hard to believe.
