predicted final gravity 1.015....I got 1.010. To be fair I am not 100% sure of my hydrometer but if it is correct is this a HUGE deal as far as taste?
Nope, just drier.
not likely to make a big difference. not unless you are making hard cider.
ok thanks guys. Just checked some wine I made from concord grapes and it is .990. SOO I checked the hydrometer in water and it is dead on.
I prefer my beer to finish drier. I think I have only had one finish above 1.010 this year.
