Not sure, those are the only 2 readings I have taken. The kit instructions say to let it sit a couple more days and check the SG again. If it is done falling will that have a bad effect on the wine?
well first never trust a kits time table. they almost alway rush the brewer to the bottle so they can sell more kits. assuming it is done falling your wine will be fairly sweet tasting. but seeing as your aiming for 0.998 i would say your either not done fermenting or stuck. only your next SG reading will tell. just leave it in the primary till the SG stops falling.
Ok, checked the SG today and it is still at 1.010. I figured that fermentation was stuck so I added some yeast and will let it sit a few more days. Is that the right thing to do?
