All my experience is in sugar wash for fuel experimentation. 20-25% ABV is common.
on the 15th I started a cider ferment.
1 gal Kroger apple juice
2.8 oz cane sugar
1 teaspoon yeast nutrient
1/4 teaspoon yeast energizer (mostly DAP)
Aerated juice with 3/4 liter per minute O2 for 2 minutes with air stone.
KV-1116 Yeast re-hydrated in 1/2 cup water.
Starting SG 1.056
Pitched at 8/15 9:30 PM. By 11:00 pm it was starting to ferment well.
8/16 10:00 am it was going nuts. temp was up to 74 deg in a 68 degF room and the S-shaped airlock was going 120+ a minute. 4:00 pm 160+ per minute at 78 degF. I set the jug in 1" water with a towel around the jug and the end of the towel in the water. 11:30 PM temp was down to 72 and 128 per minute so I was happy.
8/17 7:00 pm was visibly slowing down and temp was at 70 degF. Took a reading and it was at 1.004 SG. 11:30 it was down to 8 bubbles per minute.
That dropped much faster than I expected. I understand it wasn't a high SG to start but is that kind of drop normal in 46 hours? Did the 78 deg temp really sped things up or did the oxygen really help? All of the above?
I intend to let it go till it clears which I expect to be at least 4 weeks. I am just surprised it went this fast.
Any and all comments welcome.
