I bought a hydrometer and test tube today and measured my blackberry (very dry) second racking. The specific gravity is 990 (the very top of the meter). I'm glad I had the tube because I was close to fishing for the hydrometer. Anyway, I would like to sweeten up the wine by adding sugar or honey and sugar. My question is... Should I sweeten a small amount, 1 gal, to taste after stabilizing, or...should I sweeten to a specific gravity?
I honestly don't know how much the sweetness will change with ageing.
