Hi everyone.
2 days ago I brewed an AG imperial stout (OG: 1.100), plan on aging it ready for christmas!
After vigorous aeration (done with a massive whisk) I pitched a 2L WLP002 yeast starter when it was at temperature - 66.3F, however, I've noticed a large lag time, and then strange behaviour after.
After 18 hours there was no change, I then went to stir it and saw a large krausen forming. There is now constant bubbling, a great smell, BUT, my BrewPi tells me that there is and has been no increasing temperature, which has happened in all previous brews, and which is expected. It's clearly now fermenting, but I'm pretty concerned (and incredibly impatient!)
I have some concerns about the starter I pitched, I know the yeast was approaching its best before date and may have been pitched colder than the wort. Maybe underpitching caused the delay.
Am I massively overthinking the whole thing, or should I pitch another vial of WLP002?
Cheers
