It’s often that while you are drinking an expensive bottle of wine, there is some left over and you are too drunk to take that little. Also, in case of parties there is a good lot of uncorked wine left over. In those cases, mostly people keep the left wine in the same bottle without any precaution. This spoils the wine. The main culprit is the air inside. Here I’ll share some useful tips to safely store left over wine.
First of all, let’s talk about why the left over wine gets spoiled. Wine reacts with O2 (Oxygen) present in the air to form Acetaldehyde which spoils the taste and mood of the wine. So, while storing wine, the first safe method is to pump out air out of the bottle. Another more effective option is to inject inert gases inside the bottle. Inert gases do not react with wine and so, the wine remains fresh for long time.

For the first method you will need special hand operated air pumps and corks to suck out the air. The pumps are usually costly and cost anywhere between USD $200 and USD $350. Second method is more economic as well as more effective. Inert gas injector canister costs about USD $10 and you can use it several times. To use it, you spray it inside the bottle and cork it as fast as you can. It prevents the wine to get oxidized and hence preserves them effectively.
