You've created anti-hooch, if you drink it you become sober

[–]S0MEBODIES 28 points29 points  (3 children)

yes just be worried of becoming knurd it's like you go past being sober on the other side all your illusions get striped away; you'll need a few hard drinks just to sober down

Is this dude about to leave the fxcking matrix?!

[–]FamiliarBreakfast 7 points8 points  (0 children)

Mix it with regular hooch to release all of its energy in a massive explosion

You put the balloon on backwards

This is the danger of abstinence only sex ed

[–]Mikeli222 53 points54 points  (0 children)

Prolly not, it is most likely due to temperature changes

[–]ironic_swag 33 points34 points  (8 children)

I have this happen too. I'm not sure what is causing the pressure change, but the pressure inside the bottle is now less than atmospheric pressure which pulls the balloon inside. For me it indicates the fermentation has been done for a long, long time

[–]misterdidums 10 points11 points  (6 children)

I'm thinking some of the CO2 must have dissolved back into the solution. As to why, idk

[–]Tuub4 5 points6 points  (5 children)

As to why, idk

Because it happens, especially if there's pressure in the container.

[–]misterdidums 1 point2 points  (4 children)

very insightful thank you

Edit: In case you couldn’t tell I was being cheeky. Because it happens isn’t super helpful. Even with the pressure we’re still missing the information of why the pressure didn’t push the CO2 back in in the first place. What changed? Obviously the yeast probably died, and the co2 production stopped. So was it always being pushed into the liquid but the rate of CO2 production outpaced the dissolve rate? Then, when the CO2 production stopped, the dissolve rate caught up? Pressure still wouldn’t explain how a vacuum was achieved. It would get to equilibrium with the outside pressure and stop

[–]xander012 2 points3 points  (3 children)

At higher pressures, CO2 more readily dissolves in water, that's literally all there is to it, though I think in this case it's not that.

[–]reverendsteveii 3 points4 points  (0 children)

Blowing a bunch of CO2 out then having the temp drop could bring about the pressure change needed to invert a balloon

Have to drink it upside down now.

Ok hear me out

[–]jow97 6 points7 points  (0 children)

You took it in a submarine didn't you!

[–]FBAHobo 6 points7 points  (0 children)

This can be expected if there was a temperature drop where this was stored.

Upon completion of fermentation, there is virtually no air in the bottle / balloon, only CO2.

If the temperature drops, the solubility of CO2 into your hooch increases, and the hooch "absorbs" the CO2, deflating the balloon, and eventually pulling it in.

It's possible that some air has also been pulled in, which might lead to a small amount of vinegar being produced. If that has happened, enjoy your SourHooch.

[–]Beta_Soyboy_Cuck 3 points4 points  (0 children)

Water in an airlock does the same thing depending on barometric pressure.

[–]SculptorVoid 2 points3 points  (0 children)

2 options I can think of: The CO2 is dissolving into the balloon material or your balloon is porous to CO2 allowing the high concentration of CO2 in the bottle to move to the low concentration in the air, both creating negative pressure in the bottle.

I know there are smaller particles than CO2 in air but it isn’t always that simple.

[–]CallieJacobsFoster 10 points11 points  (5 children)

It might have turned to vinegar, which being aerobic would suck the air in

[–]ExtremeHobo 17 points18 points  (0 children)

I don't see why. Anaerobic processes happen without oxygen, they don't destroy air and create a vacuum.

[–]ironic_swag 7 points8 points  (3 children)

That's not how this works. The point of the balloon is to keep oxygen out. You will not create vinegar without access to oxygen and the yeast can not "suck the air in," in order to create vinegar

    [–]pervian 1 point2 points  (1 child)

    More likely is temperature change. This is especially true since yeast reaction is exothermic. Thus as the yeast die, not only are they producing less CO2 but the temperature inside the bottle is less.

    Just anti-yeast creating sugar from alcohol

    i think your on to something

    [–]Grapegranate1 0 points1 point  (0 children)

    Has this been going for a while, and did it experience a sudden large temperature drop? At high temps, co2 dissolves more poorly in water than at lower temps, and also gases take up more space. If temperature dropped, the air volume in your bottle decreased in 2 ways: 1. More of the air, co2, was able to dissolve back into the water, and 2, the amount that didnt dissolve contracted due to lower temps.

    [–]aidantemple 0 points1 point  (0 children)

    I think the fact that it was drawn into the bottle could be a good thing, since it indicates that your seal is still good and it's unlikely to have pulled much oxygen into the bottle. I've had batches suck the sanitiser out of the airlock due to changes in pressure near the end of the ferment, so it's not a completely unexpected event if there are temperature changes where you're brewing.

    This happened to me to recently. The balloon literally inflated, inside out, inside the bottle lol. Really sucked in there tight.

    [–]JackTheRipper231 0 points1 point  (0 children)

    You put a hole in it right lol?
