So after 8 days of fermenting some cranberry juice, it semi abruply stopped and has suck back through the airlock. This didnt happen with the other batches ive done. What gives?

Temperature change? If your fermenter cooled off significantly you could get suck back.

No, i had a strand of lights around it the whole time. Maybe its just done? It liked being over 80 degrees (off the thermo scale). I unplugged the lights a few days ago and within an hour fermentation had slowed significantly because of the temperature drop so i plugged them back in.

That is pretty high of a ferment temp. If it dropped back down to ambient temperatures, then you will definitely see a slowed fermentation, perhaps combined with a change in humidity caused the suck back.

Maybe your fermenter was just puckering.

I know cranberry juice makes me pucker.

Guess number two; it was so warm the vodka in the airlock evaporated.
Guess number three; someone in your house needed a drink really bad.

so i just tried some, and its ****ing amazing. BUT, the hydro reading is like 1.035. I dont understand how its still that high after fermenting like crazy for many days. Do you guys think i killed off the yeast with the temperature? Should i pitch another? is there a reason why the SO4 would have given up with cranberry juice?

let me know what you guys think I should do

When you take a reading, make sure to dunk than hydro down into the beer a couple times to knock off any CO2 that may be clinging. Those CO2 bubble like to gather on your hydro and cause it to float.

yep, i did that

nickmpower · 02-09-2009, 04:06 AM

so i pitched another packet of yeast, and added another cup of sugar. I guess i should have added the cup then waited to see if anything happened before pitching another packet. oh well, its bubbling
