I started 2 almost identical batches of raspberry wine in the basement to see the affect of cooler temperatures. The only difference is size - a 1-gallon batch destined to be a dessert wine (step feeding, another yeast will be added) and a 3-gallon table wine. Starting SG was 1.090 for both. One gallon started with a half packet of yeast, three gallon with a full packet.
After 48 hours:
1 gallon - 1.048, 61F
3 gallon - 1.072, 64F
I expected some difference just because of the size, temperature certainly, but the large difference in SG was a little surprising.
