Bad wine

[catfishhoward]

I was told after you open a bottle of wine it starts to go bad about a week so what is stopping my wine from going bad in the gallon jugs before bottling? I've racked a couple timea and plan on leaving them in the jugs until Christmas before back sweetening and bottling but if its true that wine goes bad after opening what is stopping mine from going bad sitting in the jugs? Even if I follow the book it says to rack twice and bottle at 2 months?

Wine typically goes bad due to oxidation. You keep your wine from going bad in the fermenter or aging vessels by one of three ways:
1. Active fermentation produced CO2 that pushed air/oxygen out of the fermenter. Plus yeast use the oxygen present in the must during the initial stages of fermentation.
2. In aging vessels, you want to minimize head space by filling that one-gallon jug all the way to the neck. Also, rack with minimal splashing to prevent excess oxygen contact. Then use an airlock or some other device to prevent air from getting in. Some air will diffuse through an airlock based on pressure and concentration differences between the jug environment and the room environment, but it is minimal.
3. Adding sulfites to wine during the racking procedure. The sulfites are an anti-oxidant and will help by scavenging oxygen that is present in the wine.

So when they say wine goes bad quickly after opening the bottle it's because of oxygen in the bottle because of drinking the wine so my wine could go bad as well if I don't fill the bottles up to the rim. I will put some marbles in the jug missing a little wine and put the others in the 32 o/z bottles until Christmas when I plan of back sweetening them.

Next time I will run just a little extra wine to fill a 16 o/z bottle with a airlock so I don't have a lack of wine next time.

Im new to this but after i fill a 5L demijohn i have about 2L left, so im going to use this to fill the demijohn after i rack and then ill bottle the rest and drink un aged while the rest age. I transfered at 1.010 so the small one has a blanket of CO2 over it so i hope this is enough to protect it untill they both clear enough for second racking.
