I got the extract kit in April and didn't boil the wort until July. The yeast was in my shop at about 60 to 75 degrees for that time. I can imagine not following this unbelievable story.
I poured 40 bottles of the ale into the ready to ferment 5 gallons of Porter and pitched the yeast.
I asked a friend who has a brewery and he wrote this:
"Do you have a hydrometer to check the sugar content? That’s the only certain way to know if it’s fermenting or not. Just because you don’t see bubbles or foam doesn’t mean that it’s not doing its job, especially if you lift the lid to smell it, which would release any pressure that would otherwise make bubbles in your air lock.
If you have a hydrometer, I would check it with that after a few days. If it’s the same as it was the day you pitched the yeast, I would add Safale US-05. I’m not sure which Safale you got before, but some don’t like to work in low ph ranges. Finished beer has a lower ph than wort, and dark malts like in a porter lower the ph too. Sorry for the technical mumbo jumbo, but I’ve had a fermentation stall on me before using S-04 in a beer with a lower ph.
If you don’t have a hydrometer, I would let it hang out for 3 weeks since you pitched the fresh yeast. Then, taste it, and if it tastes good I would bottle it like normal. I would only add more yeast to the wort if it tastes very very sweet. If it is very sweet, I’d add US-05."
If that still doesn’t get fermentation going, then I’m stumped. The only thing I could think of after that is adding yeasts like a dried Kveik yeast or Safale BE-134. These are known for eating anything and working quickly, but will add a Belgian beer character to your beer. You could add Gluco Amylase enzyme (Yes, this is probably at the Homebrew shop.) and even more us-05. This enzyme breaks down all of the long-chain sugar in the beer into very fermentable short-chain sugars. It will make a very very dry beer with a higher alcohol content than you were planning. You’ll lose the body you’d want in a barrel-aged beer, but at least the fermentation could finally get going.
