Tannins in beer. Would they mellow out with time?

I just tried an IPA recipe that I cooked in April but is really astringent and husky.
Would the tannins mellow out with time?

Maybe, maybe not. Are you sure it's tannins? I hear that flaw misdiagnosed more than any other.

well the beer smells good and hoppy, medium body, sweet, grains that ends with warm of alcohol (7%), the aftertaste is husky and dry also like the description of tannins. I don't think is infected.
what other signs should I look for?
