I'm just sitting here musing...
I make my own wine and if I feel like taking a day, I make my own beer.
Yeast is very, very inexpensive, (I get mine at GerapeStompers.com - Montrachet), and I wonder if anyone ever used yeast to start their FF?
O' course, Granny takes care of the still (Beverly Hillbillies) ROTFLMAO!
If you make 5 gallons in a bucket, and ferment it and use all bit about a gallon, then refill your container, stir it up good, what's left will re-start your fermenting.
(A little trivia: That is sorta how sourdough bread was made "in the gold rush days". They saved a bit of the dough to make the next batch. It was a very precious thing that got carried on by the bakers of the day, and some of that original "recipe" is still around today and very protected by the owners. Read James A. Michener's Alaska...).
So, has anyone used yeast? Maybe Fleishmann's bread yeast would suffice, since you're not making a connoisseur wine... ?
