OG13 – The Dark Side of the Moon

Back in the summer I brewed up a black IPA, which I called Supermassive Black Hole. As a brew is showed great promise, before the bottom of the King Keg it was in split and emptied iself over the kitchen floor. Back in January I decided to revisit the style and came up with:

Dark Side of the Moon

This was my first attempt at full water treatment, using CRS to soften the water and adding a teaspoon of gypsum to the HLT. The wort ended up a little short of the target OG at 1055, was fermented at 18C with US-05, and dry hopped with 12g each of Summit and Amarillo after the first week of fermentation.

FG hit 1012, so the result was a solid 5.8% or so. It’s now sat in a Cornie. Taste wise it’s slightly more ‘burnt’ that the cold steeped Supermassive Black Hole, and I have a feeling that the ‘dehusked’ Carrafa II might actually be the husked version. It is, however, a robust, hoppy brew.
