Bitter after taste

[maan]

Hi,

This is my 2nd batch of home made wine. I did Cab and Zinf back in 2021, which turned out pretty good.
Y'day I tasted my 2022 Merlot from one of the carboys, this is my 2nd tasting it. The first one was in early 2024. I feel like
it's turning bitter, especially the after taste. It tastes pretty good at the pallet in the beginning but the after taste is very bitter.

What could be going on ? Is there a way to fix it ?

Thanks in advance for the help.

I made a batch of Merlot a couple of years ago that was quite bitter. My suspicion (speculation?) was that I really pressed too hard and got lots of seed tannins.

I decided to just let it age and see if it softened up. You have inspired me to do more (ahem) "research" and open another bottle to see if it has improved. I will let you know the result, but not today.

But I wanted to mention that it was recommended to me to try using PVPP (Polyvinylpolypyrrolidone). This is commercially known as Polyclar (See it at Morewine: https://www.morebeer.com/products/p...L9cRUx_VwynPcjrmqmXQGqQrYrA-7INRpb3umoaxsL6Am )

I did not try this, as I decided to just try waiting.
