Wine got worse with Age?

[roberto188]

So I followed a banana wine recipe from Jack Keller's website. After about 4-5 months of racking and bulk aging and putting the appropriate amount of K-meta at everyother racking I bottled it. At bottling, it had a subtle banana flavor, had a VERY buttery moutfeel, but was a bit "HOT" tasting. After about 1-2 months, I popped open a bottle, and the "hot" taste was gone and the banana flavor came out very nicely and had a nice buttery mouthfeel still. It's now been bottled for about 4-5 months and I just opened a bottle and the mouthfeel of the wine seems thin, and the banana flavor is a bit muted and now there is a bitter aftertaste, almost like the actual peels. The wine was backsweetened just a tiny bit and I added potassium sorbate at bottling. Is it possible this wine is actually getting worse with age? What is going on?

Also, I bottled a blueberry rose wine that at the time of bottling seemed VERY acidic. I popped open the bottle about 2-3 months later and it now seems thin and lifeless. What is going on in both of these cases? Should I just keep aging these wines? The recipes said at may taste at 6 months, but to age at least a year.

Any thoughts?

It sounds like some oxidation. Is the wine darkening a tiny bit as well, and developing a brandy-like flavor? (That would be severe oxidation).

Upon closer look, yes it appears that the BRIGHT yellow color I had is now SLIGHTLY faded with an ever so slight tint of brown. I think you are right, it is oxidized. I must not have sulfited it enough before bottling.

In regards to the blueberry wine, I didn't bulk age that long and I think MLF had not yet taken place before I bottled, which is why now, when I pop open a bottle the TA is about .45 instead of the .6-.55 that it was when I bottled it. Simple 1.5 grams of acid blend when the wine is decanted, has "fixed" my error in that regard, so the blueberry rose is still salvagable.

Lesson's learned:

Make sure to have PROPER amount of sulfites when bottling. And be sure to bulk age long enough for MLF to complete before bottling so that your TA doesn't change while bottled.
