After pouring, crush the bottle enough to dispel most of the air so that the fluid is a few mm from the cap and replace the cap tightly.

- FreeFull 10y agoThis doesn't help at all, unless you take steps to keep the bottle from uncrushing as carbon dioxide inevitably comes out of solution. What does help is keeping your drink refrigerated, because gases dissolve better in cold water than in hot.
- barking 10y agoSo if you do take steps to prevent the bottle from uncrushing would it work then? Some sort of a simple vice, perhaps?
- FreeFull 10y agoRight, then as the carbon dioxide pressure builds, it'll reach equilibrium sooner, so not as much will end up out of solution.
- CraigJPerry 10y agoHere's how I reasoned about this, but this isn't my forte and I'd welcome any corrections! The pressure of gas in the bottle neck increases as degassing occurs but only until an equilibrium is reached. The equilibrium occurs at a pressure lower than that required to deform the tough plastic in the neck of the bottle and lower than that required to overcome the soft bottle body plastic connected by hydraulic advantage to the gas via the small cross sectional area of fluid in the bottle neck.

- barking 10y agoIf coke came in something like the boxes of wine that used to be around one time, They were in effect a bag of wine with integrated tap inside a rigid cardboard box. As you drew wine through the tap, the bag collapsed.
- Semiapies 10y agoThose still exist.
- jandrese 10y agoBox wine is still a thing, although it's hard to find anything good in a box. This probably won't work because the CO2 will just inflate the bladder after you pour your first drink. You'll end up with flat Coke and a bag full of CO2 by the end. Also, the cheap plastic valve would probably fail and start to leak if you put a carbonated beverage in there.
- CraigJPerry 10y agoThe typical bottles we have won't recover their original shape when crushed. They will attempt to reform slightly but only slightly. I believe the pressure in any pocket of gas in the bottle would increase due to degassing of the fluid and this pressure would have a greater impact. Especially if that degassing was encouraged - e.g. shaking the bottle. In contrast, I can't see that manipulating the bottle in an attempt to recover its shape would encourage further degassing.
