I just did an English style pale ale a couple days ago. I've read a little about Esters and how they can produce fruity aromas in the off gassing during the fermentation. What the heck is going on? The gas coming out of the airlock smells like the inside of a shipping container full of ripe bananas. Can someone give me a little more in depth idea of what esters are? Does that aroma go away?
