So I've done the background by reading Schramm. My plan is to take the 5 gallon show mead that started fermenting 4 days ago and add rack it onto some fruit in 1 gallon carboys, each with different fruits and alittle more honey, and one traditional mead. I have just found out that the raspberry season doesn't come around for another 2 months or so :'(. My question is; how long can I leave the must in the primary? I'm more concered about complete fermentation and no beasties left when I rack to the fruited secondary than I am with off flavor.
