So brewing my first batch and have a problem, fermentation started off slow and stopped. I know one mistake I made for sure I forgot to get starting SG reading before adding yeast and air lock. As it stands right now after 3 days in the fermenter the SG is at 1.020. After 24 hours I was expecting a fierce bubbling fermentation, as my friend put it, but there were no fireworks. So I cracked the lid on the bucket and you could hear some yeast bubbling. However after 48 hours and now 72 hours absolutely nothing. Here's a rundown of what I did (5 gallon recipe for porter from Rogue Valley Brewing Supply) ) 1. brought water up to 155F removed from heat added grains in bag for 30 minutes lifted bag and let the grains drain off into brew pot. Brought that to almost a boil then added malt extract returned to heat brought to a boil added 1 oz of Mt Hood hops continued boiling for 45 minutes added 2nd oz of hops. At 60 minutes removed hops (in a brew bag) added 1 tsp of yeast nutrient. Cooled off to 85F and added another 2 plus gallons of cold filtered water to bring up to 5 gallons and stirred. Wort temp was at 75F at this point and I pitched the yeast (Imperial yeast ale house A01). I later read in the yeast specs that this yeast has a temperature range of 60-72F. Only thing I can think of is maybe the wort at 75F was too much and I killed them off. Could I add yeast energizer? Should I make a yeast starter with another bag of yeast and pitch that? The problem with yeast is the brew store is closed until Tuesday. I could use a different brand of ale yeast, but the local store that carries yeast has a different brand. Any help would be greatly appreciated. Thank you. Oh I did stir gently this morning after taking SG reading everything smells OK and tasted what was in the SG cylinder and it tastes fine too.
