Well, the first brew day of the season kicked off on Sunday. I had stopped into High Gravity in Tulsa to grab ingredients, but had forgotten my recipe sheet. Ended up grabbing 7lb of Golden LME, .5 of 6-Row, .5 Carared, and .5 of Caramel 120. I didn't grab any yeast, as I usually have plenty on hand. And this being an fairly generic ale I figured US-05 would be fine. For hop I chose 2 ounces of Cascade pellet. Added 5tsp of Yeast nutrient at 5min. Boil went fine, although I did notice that I was getting more protein coagulation at pre-boil, like a lot. More than I normally see at post-boil. But aside from that, everything went fine and I hit all my numbers.
After chilling, I transfered to my new 6.5gal carboy, and here is where it get interesting. I didn't have any US-05, All I had was US-04. So I sprinkled in a half packet of US-04, rigged up my blowoff tube, and placed it next to my floor vent with a blanket around it.
Fermentation got going after about 5-6 hrs. Temperature has been maintained at 68F, and fermentation was vigorous, with a strong krausen, lots of visable movement in the beer, and a bubble from the 1/2" ID line a fraction faster than one bubble a second. Everything was looking great.
This morning I woke, grabbed a cup of coffee, and went to check on my beer only to find that the fermentation had slowed. The Krausen had fallen, and the bubbling had slowed to one bubble ever 2 seconds or so. And the beer looked almost still, with little movement inside.
Typically I don't start seeing this for several days when the fermentation is rolling to a stop. But less than 48hrs??? Anyone experience quick fermentation like this? It throws me off, because the only time I've every experience anything like this was when I had a vast over pitch. But with only half a packet of yeast, and a 68F maintained temperature, it doesn't seem like it should be getting done this fast.
