Yeast

[Kristi Anderson]

I can’t believe it but I forgot to kill the wild yeast. We picked, I added pectin enzyme and optional-red, waited a day then activated purchased yeast and go-ferm this evening and added it to the grapes . Then realized I never killed the wild yeast. What do I do?

Nothing to worry about. Your cultivated yeast will overcome any of the natural yeast that was on your fruit. K Meta doesn't really kill the yeast, it just makes it harder for it to flourish. No worries. It should turn out fine.

Some winemakers ( @4score ) pay extra money for non Saccharomyces yeast to get more complexity in their wine. The additional benefit of the initial SO2 is to also kill any bacteria, but assuming you had clean fruit, you should be fine.

I stopped killing the wild yeast with sulfite a few years ago and have never turned back. My fruit is always decent and having no sulfite at crush makes things easier for MLF. You should have nothing to worry about.
