I'm fairly new to wine-making (about 3 years) and am still exploring what recipes & yeast combinations give me the outcomes closest to my goals. I have a couple of recipes that I am really happy with that my preferred yeast is only available to me as a slap pack. This in and of itself isn't a problem but I live in Alaska; the supply chain up here can be weird even when nothing else is going on and because of the freight and handling requirements, it's relatively expensive. Would it be possible to buy a slap pack, split it up into sterilized mason jars, feed it up a bit and create a yeast bank for multiple pitches?
