Brewday 51: Isolation IPA

Brewed 05/04/2020

I guess that I can thank the COVID-19 lockdown for forcing giving me the impetus to get the brewery up and working and the first new brew in over 2 years on the go!
The comeback Brewday will be a relatively simple IPA. As this is also the first brew on the Demon Valley Brewing v.3 kit there is intentionally nothing too fancy or clever with this recipe. Basic malts, basic hops and a reliable yeast. Simples.

The recipe for the Isolation IPA:

  • 5.2kg Maris Otter Malt
  • 300g CaraPils Malt
  • 200g Crystal 200 Malt
  • 15g East Kent Goldings hops @ 60 minutes
  • 15g Northern Brewer hops @ 60 minutes
  • 20g Citra hops @ 15 minutes
  • 36g Citra hops @ Whirlpool
  • 1 tsp Irish Moss
  • 1 pkt Nottingham yeast

Again, to stick with simplicity, this will be a 60 minute, single stage Mash at 67C followed by a 90 minute boil. The new kettle has a whirlpool attachment so following flameout I will be recirculating the wort through the whirlpooler to ideally gather all the hop pellet sludge in the center of the kettle and not transfer it to the fermentor! I am hoping the little brown pump is up to this task for today but a new pump is already on the shopping list!

Hops! Northern Brewer, EKG, Citra and Citra. (from left to right)

All finished!

Not the clearest sample! 1.048 OG.

Brewday 51 was going perfectly to plan until the whirlpooling at which point the little brown pump struggled and then died completely! It was clearly just too old and too under-powered for the task at hand, the new pump on the shopping list just went up a couple of places in priority! Due to the unfortunate demise of the pump, the whirlpool was a abject failure and all sorts of hop sludge transferred to the fermentor with the wort! This shouldn’t cause a big issue in the final beer though as it will be crash cooled once fermentation is complete to drop all this out of suspension before kegging. Fingers crossed!
Another priority job is to set up the Grainfather Couterflow Chiller for use with this new kit. The copper immersion cooler worked ok today but has a small leak (outside the kettle) and is nowhere near as efficient as the counterflow chiller. It should be a pretty easy task to swap out the connectors for use with this brewery kit. One to complete before Brewday 52.

All in all though, Brewday 51 was pretty successful. I ended up with 24l in the fermentor instead of the target 21l, and the OG was 1.048 instead of 1.057 as a result. Presumably the boil wasn’t as vigorous as needed because the pre-boil volume was spot on. I will be double checking Beersmith 3 to make sure there are no obvious errors in there too though!
