I've got good news, I'm going out to dinner with my wife tonight (local brewery).
The not so good news is that two of your wines need some more MLB, or more time. Zin looks done.

I need to also order some supplies for doing the tests since I'm running low (that big blob of Merlot was from me trying to get a single drop out of the syringe and save a pipet).
Those are my Merlot and Cab from 2017. Guess 4th time is not a charm.
