Balloon airlock

[denverlong]

I started my first batch of wine. I used a three gallon better bottle but only filled half way up during the secondary fermentation. The balloon was nice and full for about two weeks into fermentation. Now it has sucked into the bottle and expanded to fill nearly all the empty space inside the bottle. I know now I should have used a more appropriate size fermentation vessel but what is happening in the bottle?

I'm thinking its that fermentation is over and the Air pressure (barometer) where you live has dropped. Like you said U need to get a airlock.
What are you making and give all stats and what you did so far. Whats the gravity now?

 

[denverlong]

well I started with grapefruit juice and shaved grapefruit rines. The primary fermentation went fine and after one week I moved it to the secondary. I'm not sure what the specific gravity. I haven't opened the bottle to check. will air pressure cause suction?

Sounds like the balloon is taking up the head space....funny how things work out.

 

[Tom]

Yes and temp
I hope you have a hydrometer. Check the gravity.

 

[denverlong]

Its about seventy two degrees. I have it in the closet with the hot water heater.

I beleive he said hydrometer not thermometer

 

[denverlong]

No hydrometer here. I usually make shine so this is new.
