1962 London Pride with modern hopping v0.1

I’ve been following Ron and Kris on Ron’s blog with their Let’s Brew Wednesday series. It is a interesting site to learn about beer grists and brewing techniques, drug from beers that were actually made and sold to people, order most often 50 or more years ago. Not that that makes them any better, but at least they can’t be too horrible. I had been eyeing the 1962 Fullers Gyles – doing a big set of gyles one day would be fun. Sadly, I’m a single boil kettle guy for now and need to hold off until I can boil both worts at once. No sense screwing it up on purpose…

I figured the export London Pride was a good place to start – I can compare flavors/mouthfeel with the commercial example and the extra gravity can hide some mistakes in hopping. The Fullers website lists different hops than Kris has in the 1962 recipe, but I dug around a bit to get info on their modern hopping. There were a couple of forum posts that seemed to have a reasonable hop schedules, so we’ll give it a whirl. Why switch it up? I had some older Target and Challenger hops that need usin’. Yeah, even I get cheap sometimes.

Brew Day Fun: So I had Rick and his Dad over to do some brewing and beer tasting… all was going well, besides me getting fancy with mash water calcs and blowing the temps, until the wife got a nasty migraine and needed to get to Urgent Care. So, out the guests go and to the Dr. we went. All was well shortly and she has some new drugs. I got lucky brewing-wise and was able to finish the sparge and push the boil kettle to 180F before tossing a lid on it and turning off the flame before the road trip. 2hrs later we were home and I finished the boil – amazingly enough the wort had only dropped down to 160F.

Challenger/Northdown are 30min hops, but I'm adding at 1 min and doing a 60min whirlpool.
I calc'd them at 30min for utilization, then adjusted 90min down to get 36IBU.
