Pigpen when you ask where to start, do you mean with fresh fruit or what?
donking2010, each kit lists(at least on George's store online) the time to peak. Use that as a guide. You can figure it will last a few years past that, as long as you have good storage and ADEQUATE SO2 levels. If you added 1/4 tsp k-meta and are bulk aging for 6 months, the SO2 will be just about gone. You should test the level and then brin it up to about 50ppm free SO2 before bottling. This is about minimum if you want extended aging.
