Does anyone else have an issue with their flavor and aroma fading quickly? It seems that I'll brew an IPA and it tastes and smells amazing but that fades out within a couple of weeks (not months) leaving not a lot more than bitterness. This seems to be happening consistently, regardless of the recipe. I think I have been cooling my wort too quickly after throwing in my flame out additions, so I don't know if that's a factor. I also think a lot of my beers are over carbonated, but I'm not sure if that is driving things off. By the way, I bottle. Anyone else experience this? Any thoughts?
