During my fermentation I kind of neglected the fact that I don't want to be introducing any oxygen into my brew, not to say that it was exposed to tons of it, but I took the airlock off a few times and even gave it a taste which is funny because while tasting it I realized the problem, but by tasting it I made the problem worse lol. I'm not at all worried about the sanitation risks in doing that, because every time I did I kept everything really sanitary. I'm just worried about the slight off flavor the beer has, it's good, but I could just taste this slight off flavor. If I leave it sit on the cakes long enough should they go away? Is there a way to recover?
