So I started my first brew last sat. I checked today and the once thick foam has almost entirely disapeared. Its been kept at about 18 degrees. When I open the bucket it smells really beery but sweet. It seems very quick for fermentation to have finished. I have a hydrometer to check SD but I thought I would ask you guys before I risk contaminating it. So is it good? Quick? Ruined etc? Any advice would be great. Thanks
There a lot of factors that determine how long the fermentation take and/or foam will last. Recipe, yeast and temperature among them. At 5 plus days there should be no concern about the foam having dissipated. It is unlikely that it is ruined and normal to smell sweet. The fermentation may not be finished yet. Now wait another couple of weeks then take gravity readings to determine that you have reached final gravity.
I was scanning through the threads quick and saw a thread about fart foam. I was intrigued. I'm now here and realize two things. One, there is no discussion of fart foam. Two, I should read slower when I'm tired.
Sanitize your hydrometer and just let it float in your beer. Spin the stem of the hydrometer when you let it float as that will shake off any bubbles stuck to it. Take your reading, remove hydrometer. Easy peasy.
