I just finished my first attempt at brewing a few hours ago and was wondering if what I noticed was normal. First this brew is an Irish Red Ale. What I noticed was after I added the LME and before the wort came to a boil there was a little formation of foam.
A few minutes (~3 min) later I saw the first boil bubble and added the hops. All the foam disappeared and didn't come back. Is this normal?
Just curious. Thanks.
