Hey everyone,
I bought a wine kit from my favorite brew shop and have a small question about the gravity. The instructions on the kit say that I'm ready for the next step when my gravity is stable at 0.996 or less. Well it's been stable at 0.998, is this going to make a difference when I move onto the next step in the instructions? I know I read something somewhere about this not making a difference, but I thought I would ask.
For those who are curious I bought the Mango-Citrus Symphony from WineExpert.

Thanks again,
Shawn
 
I can't imagine that the 0.002 difference is going to change anything at all. As long as you're sure it's stable. Exactly what step are you at right now?
 
Well, according to the kit I'm ready for step 3 (Stabilising and fining). The instructions say that if the wine is stabil then I can add the extra juice, sorbate, metabisulphite, and the chitosan/isinglass clarifier. I can't imagine that I've messed anything up to this point and I didn't think .002 difference in gravity from the instructions would make a difference, but I thought I would ask.

It may be a bit late for this particular situation, but for any future lurkers...

Consider that the gravity reading on a hydrometer is going to be affected by temperature. Make sure you read the temp adjustment chart that comes with the hydrometer. On mine, a temp plus or minus 10 degrees can swing the reading much more than .002

Even if your sample is at dead 70, or whatever the hydrometer is calibrated to, the simple act of plopping in a hydrometer than may be 75 or 65 degrees will change the temperature of the sample immediately, so using hydrometers like that is always going to have some kind of margin of error around .002 or probably a little more.

And guess what? I'm no expert. I just read the instructions!
