Hey all, first post here... glad to be among some experts while enjoying my new hobby!
I am in the fermentation stage of my 2nd batch of beer and the fermentation is acting completely different from the first, and also different from everything that I've read. I bought a Porter kit (brewer's best, I think) and followed the directions all well except that I had to boil a little less water than it called for. Instructions said 2gal. but with my smaller pot, could only fit 1.5 with 2 cans of extract. Anywho, everything went as planned, racked the beer in the fermenter at about 11pm and at 6:30am the next morning, it was already giving off a lot of gas bubbles, and much more rapidly than my first batch. Figured it was because I pitched it a little better this time and aerated the beer better before pitching (after it was already at 70deg.). But later that evening (14-16hrs later) The gasses had stopped. My first batch didn't start fermenting for at least 24hrs and stopped almost 2 days later. Should I be worried?
Oh, and one more thing I did differently was that I tried to fill the fermenter up with CO2 before sealing it. Somebody had suggested this to me to help minimize the oxygen content. Not sure if this was a good idea or not figuring that the yeast needs oxygen as it's fuel right?
Sorry for the novel, just a little concerned.
