Hi Birdie wife. I hope the wine was not going acidic, if it is very dry then congratulations. If you now add syrup it may continue fermenting so you need to stop it, the wine that is, by adding a camden tablet. My best advice would be to keep it in a clean container untill you find another wine or mead which is a bit sweet or maybe has a heavy body or very perfumed and blend them. Try to keep some notes as it will help you in the future, how much of one with how much of the other etc. Blending is the way to go as you do not have to acheive perfection with each brew, which is difficult.
