Beginer with questions

I am definitely NOT an expert, and I am sure that the others can answer this much better than I can, but here is what we have experienced.

We (hubby and I) are not big drinkers, I find that I like the bubblies best so far. After pouring the wine into our glasses (flutes) hubby immediately puts the cork back in, the wire over it, and then covers it with foil as tight as possible. We put the bottle on the door of the fridge in a reclining position, where the wine hopefully covers all the cork.
The next day (sometimes two days later), we open what is left and so far it stills seems to keep its bubbles. No "flat" wine yet.

We generally just throw out what is left after that, it isn't enough worth keeping.
You can also find a smaller bottle of wine and keep it to pour the left-over into, thus leaving less room for air.

Hope that was some help to you.
