I am getting some bubble gum aroma and slight flavor from some of my beers and am looking for a little advice on what might be causing it. I'm almost positive I don't have a problem with sanitation. The only thing I can think of is my fermentation temps. I don't have much control of them due to my setup but normally I stay steady at around 70-72 degrees. Is this slightly warmer than optimal temp causing this? I have gotten this aroma in everything from pale ales to wits. It's not so unpleasant that it's undrinkable but in some beers (especially ones that use wheat beer yeasts) it's definitely noticeable. It has happened on my last 3 batches and I just can't narrow it down.
