So I ordered an erlynmeyer flask, but apparently it is out of stock and won't be here until the 12th... I really don't want to wait that long to brew so I was thinking of just using a wine bottle as my starter. My big question isn't so much as if I can (I know with proper sanitation and cleaning it will be fine), my big question is how to go about sealing it, while letting out the carbon dioxide. I was think of either using seran wrap, secured with a rubber band and poke a few holes in it, or wrap it with tin foil and put some holes in that. Thoughts?
