Co2 will carbonate the wine.

Co2 will carbonate the wine.
- danwills 6y agoIt takes a fair amount of pressure or reduced temperature (or both) to get enough CO2 dissolved for the resulting beverage to be noticeably 'sparkling' (Source: Friends force-carbonating home-brewed beer in a keg (in a fridge) w/CO2 cylinder). Don't think it would happen much from just filling the air space with CO2 at room temp and pressure.
- amluto 6y agoSticking dry ice in a drink will make it taste noticeably carbonated. This is 1 atm of CO2 at the freezing point. (Carbonating to 1 atm does not produce much fizz — it only produces any at all because the CO2 offgasses as the drink warms, but bubbles and the taste of carbonation are different phenomena.)
- klodolph 6y agoYou’re being downvoted, but this matches my experience. A depleted can of CO2 gas produces weak carbonation, similar to dry ice. One of the tricks to CO2 canisters is that CO2 liquefies around 6 atm at room temperature, so a canister of CO2 will maintain that pressure until the liquid CO2 is depleted. Dry ice produces about 1 atm of vapor pressure (obviously) which matches the vapor pressure you get when displacing air.
- ridgeguy 6y agoCO2 will acidify the wine, which might well alter its taste. Carbonation (in the sense of making the wine fizzy) will not happen unless pressure is used to drive the CO2 into the wine. You need a supersaturated CO2 solution to get fizzies.
- OJFord 6y agoWhat kind of source is not pressurised? SodaStream (and other brands) work exactly this way, there's nothing fancy in the box, it's just a button letting gas out of the canister.
- GavinMcG 6y agoIt's not about the source; it's about the application. The intention with wine is to let gas layer in the bottle, not introducing it into the liquid directly.
