And the winner is... Nottingham! by a couple of lengths

I'm fermenting a porter right now which I just dumped on top of my last batch's yeast in my BMB. OK, since doing it, I've read a couple of posts indicating it was a big overpitch. The previous batch was a nut brown with an OG of 1.057 (overshot the recipe) and the OG of the porter is 1.061. It took off like a rocket and I had to hook up a blow off tube. I noticed today its bubbling really slow (I'd already put the S style airlock back on). I thought well maybe it's stalling or something so I checked it. Well, it's been 48 hrs in the fermenter and its already down to 1.018. Is that crazy? Bad, good, or just to expected? Fastest yeast I've seen in my short brewing career...

Notty is a beast. Not out of the ordinary at all.

Bubbling frequency in the airlock is basically meaningless.

My last brew was a Notty Double IPA. I pitched two packs (per 5 gallons) and fermented at 55F with no blow off. (1.070 OG)
