Stove-top Imperial Porter

So I used a 9L pot to mash in, strained it, then boiled back in the same vessel.

Then I made use of a check valve disconnect as a 5psi (?) spunding valve on 2 x 2L bottles to ferment with some kveik - mini fermenters ahoy.

Mash

The initial layout of the recipe is in Brewfather, but it's scaled down as below.

  • 1.1kg Maris Otter

  • 100g Rolled oats

  • 45g Amber malt

  • 70g Chocolate malt

  • 15g Roasted malt

  • 50g Crystal

Mashed in 5.5L of water at 67c, just loosely floating in the pot, stirred a few times.

Boil

  • 60m - 12g EKG

  • 10m - 5g EKG

Target OG was 1.098, but I ended up around 1.080

Fermentation

So this was taken with a real spunding valve on the top, but I swapped it out for a no-return disconnect when I needed the valve on the fermzilla. Basically, chucked it into a couple 2L bottles, used a T piece and some carbonation caps to keep it all under pressure, and with kveik, it was done in a few days.

An alternative pressure fermenter

That does the job
