Punk'd Up No.3

I'm at it again with my Punk'd Up (Punk IPA clone) recipes. This hop combination from Crossmyloof Brewery is easily my favourite so far from their selection of pre-mixed blends.

The recipe this time will be very similar to the previous two (here) and here. It will be 100% Weyermann Bohemian Pilsner malt aiming for an OG of 1.046. The IBU target will be 49 because the Bohemian Pilsner malt is very sweet and can easily take it and I'll be using CTZ to add bitterness.

Yeast preparation

I built my starter on the Tuesday before brew day on the following Sunday. This is a reuse of the Wyeast 1272 American Ale II that I've been using for this recent series of American ales.

Brew day went by without a hitch and I got just over 24 litres into the fermenter. OG was 1.046, exactly as planned. After chilling down to 22C with the immersion chiller I transferred the wort to the fermenter, pitched the yeast immediately and set the brewfridge for 20C.

The next morning, after about 18 hours, CO2 was bubbling out through the blow off tube. I will leave this for 14 days before kegging.

Kegging day

Two weeks after brew day I kegged it. As usual I got a full keg and a couple of bottles from the remaining beer in the fermenter.

FG was 1.006 for an ABV of 5.3%. The sample jar looked a little bit cloudier than usual so I've decided that this will be my last re-use of the pack of American Ale II yeast and I'll start on another strain for my next brew.

Tasting notes

Good as always, a fair clone of the original Brewdog beer and one that I'll definitely do again. This is a fitting fairwell to the American Ale II yeast that I've been using for this series of American ales.
