For 2019, I bought a 500 gram brick of Avante yeast. Between my use and the use by my friends, I've still got 200 grams of it. That's plenty for all the wine I might make in 2020. Does anyone know if it can be kept over the winter in the Fridge and still work next year? I have a vacuum sealer and would do that before buttoning it up. I also have a deep freeze chest freezer if that would be preferable. And if I use it next year, should I increase the pitching amount to say 1.5 grams per gallon? Not a huge deal, and I'm certainly willing to buy another 500 grams, but waste is waste so... If anyone has experience, I'd like to know.
