My last batch is an IPA that I created from scratch as a recipe experiment. I brewed 2.5 gallons.
It fermented for two weeks at 68 degrees, crashed it to around 40 for about 5 days to clarify. I then mixed priming sugar in bottling bucket and bottled. They conditioned for ~three weeks at 68 degrees.
The first bottle I tested (tasted) was a week in the bottle, flat, good taste. The second after a week had plenty of carbonation and was quite tasty. I put the bottles in the fridge 2 days ago (week three) and tried one last night, flat (maybe a slight carbonation) but good.
I can only assume that crashing pulled too much yeast out of solution to allow for consistent carbonation.
Should I have added more yeast back, if so how much and should i use the same yeast as in fermentation or is there a dry yeast that works good for bottling? Maybe use carbonation drops?
My other batches have carbonated well, but this is the first time I could control temperature and crash at the end.
Here is the recipe:
