I followed Ken Schramm’s recipe for Fall’s Bounty Cyser and I am now (cyser going into secondary) adding in the spice bag–1 tsp cinnamon, 1 tsp nutmeg, 3 cloves. I doesn’t say how long to leave it in. I really don’t have any idea how long to leave it in there.
I would taste a sample every two or three days, and when you’ve reached the desired level of spice, remove the bag.
Update–I actually left it in for about 15 days and I pulled it out today and the spice improved the flavor. It tasted pretty good. It is 2 months old. Any ideas how much longer to age it?
How long should spice be in a cyser? Long enough to reach the ground.
Seriously, I leave the spice bag in and taste an ounce or so every day until the mead is where I want it, then remove the spice bag and keg or bottle.
Once bottled, I age mine for 6 months to a year.
