when a wine bottle is cracked open oxidation begins to take place – a chemical reaction in which the wine is exposed to oxygen.
The amount of time the alcohol will last is dependent on the type of wine, how it’s stored and how much is left in the bottle.. The amount of time the alcohol will last is dependent on the type of wine, how it’s stored and how much is left in the bottle
an open bottle of white wine or rosé will last between three and five days if kept cool in the fridge.
Sparkling wine will only last one to two days once opened, so it’s best to invest in a good quality bottle stopper or enjoy a bottle with others.
In winter, opened bottles of red wine will last between four and five days, but in summer due to the heat it’ll last two to three days.
It’s also recommended to store red wine in a dark place regardless if it’s open or closed.
How long does an open wine bottle last?
Luckily, there are a number of ways to make your leftover wine last longer.
If you only have a glass or two left in a 750mL bottle, perhaps transfer it into a smaller bottle.
This will decrease the surface area and amount of air inside the bottle to slow down the oxidation process.
