WLP007 and CRAZY attenuation

So I made up a batch of india red ale, with a large amount of dark crystal, two row base and some oats. I mashed at 150 and fermented at 67 degrees. The OG of the beer was 1.072 and I pitched onto the yeast cake from a 1.040 batch of bitter......sounds about right doesn't it?

The final gravity of the india red ale is 1.008!! That is %89 apparent attenuation. I measured this at least 5 times to make sure there wasn't a mistake.......

This yeast may literally be the best ale yeast on earth.

How does it taste?

Sounds like you will have a dry finish on that red ale.

yeah, super dry i'd bet.

Also, that yeast drops like a load of bricks. If you're process was good otherwise, you'll have crystal clear beer in like 20 minutes after fermentation is complete.

After 5 days it is crystal clear and it tastes quite good. I thought it would be fiery, but that is not the case. I wanted this to be a big, red IPA so I think the dry finish will be a good thing....at least i hope.

But man, WLP007 is crazy stuff.

My guess...this is the reason for the low FG...007 is a beast and will consistently get you below 1.010 without the honey as long as it's taken care of. I re-pitch this yeast all the time and it never ceases to amaze me, even at 64F. The lower mash temp helped too.

This beer looks delicious by the way:rockin:!!!
