WLP002 - Wyeast 1968 - Imperial A09 Pub - Fuller's Yeast Strain Speed

Ingredients
1

Ok guys, I delayed my brewday because of a cold one weekend, then a stomach flu the next weekend. Now I have this 1.043 OG English Golden Ale fermenting at ~67º F with a first-generation pitch of Imperial A09 Pub (purportedly the same as 1968). I pitched the yeast at 65º F at 2:30 pm yesterday.

I had active fermentation and a three-quarter-inch layer of krausen this morning. I know this is a fast strain, but what are the chances the beer will be ready to keg Thursday night (in order to force carbonate Friday morning before work)?

Keep temp ramping to encourage it to ferment a bit faster.

I’d say good odds, it’s a low og. As long as you used a good pitching rate, which it’s likely given Imperial claims >200B cells per can.

My wife and my cats will be very happy with the warmer house temperature. I ferment at ambient in differently-ventilated rooms in the house during the cold months.

It will reach terminal gravity fast, but needs time to get rid of diacetyl in my experience.
