Bottling Question...
 

Ok so I got distracted and never got around to bottling several wines that I started over two years ago.
They went through the primary and I've racked them several times but they've been sitting under airlock in one-gallon jugs ever since.

Not sure if it matters but I have:
1 Dandelion
1 Peach
and two Strawberries.

How can I know if they've gone bad/gotten contaminated? Will they taste foul?

Thanks for your help!!!

Hopefully you added Camden tablets or metabisulfite along the way. This would help prevent oxidation.

The only way you'll know if your wine is oxidized is to smell and taste it. It may have picked up a brown color as well if that's the case.

Yes, when I racked them I added a tablet. But I haven't added any for a long time.
They color looks great- no brownish tint/color.
What would oxidized wine smell and taste like? I'm pretty much a newbie.

Taste it, if it's good drink it...if it isn't hold your nose and drink it.
