This is my second try at wine making. I made some skeeter pee first. This is for a 5 gallon batch. I put 12 cans of grape concentrate, water, and sugar together and let it set for a day. Added one pack of red star montrachet yeast. I let it work for 8 days and transferred to another carboy. I checked today, it has been 2 weeks. I do not have any activity in the air lock. Did my yeast quit working, or is this normal. The skeeter pee worked a lot longer than that. Thanks for any help.
