I'm real new to this, first timer. I mixed up a 5 gallon batch of mandarin orange from canned fruit that was packed in light syrup on Sunday. Yesterday I sprinkled the wine yeast in it and checked the S.G. and it was 1.080. Today I stired it and lightley squeezed the stranner bag and did not notice anything happening so I checked the S.G. again, this time it was 1.090. What can I be doing wrong? Any help, please.
