Imperial Hoptrooper Brew Day and Tasting Notes
On November 20, I brewed my biggest (and most successful in terms of numbers) beer – a double IPA. Recipe inspiration came from MadTree’s High series, which is a series of IIPAs that are quite popular and very well rated (note: there are three “highs” that I know of, the Galaxy and Citra, which are linked in the text, and Azacca which is not… but it’s also f**king tasty! There may have also been a Mosaic High).
The recipes are similar. I did a fair bit of ‘back of the napkin’ analysis on the two beers, looking at the percentages of grain, the AAU at each addition, etc. I ended up with the recipe below.

I kept closer to the size of the Citra High recipe, mostly because I am still working through efficiency issues (it’s getting better, though). I still didn’t get MadTree’s efficiency, but to be fair, I’m targeting 75%, not 82%!
I’m happy to say that the only issues during brew day was how long it took and higher than expected grain absorption. I started later in the day (around 2:30 PM) and it didn’t end until maybe 6:30PM. There were no stuck sparges, clogged lines or chillers, boil boiled. I ended up with about 4.5 gallons into the fermenter, which is less than the 5.5 gallons I was targeting. However, the lower volume works better with my 7.5 – 8 gallon kettle.
Throughout fermentation, the temperature (as measured on the side of the fermenter) stayed at 68, which is a nice perfect temperature.
Aroma: Grapefruit mostly
Appearance: Copper, opaque. White head that starts thick and persists as a thin head.
Taste: Tongue lashing bitterness with citrus tones. Some alcohol flavor.
Mouthfeel: Moderately carbonated, slight citrusy tartness lingers past the dry finish.
Overall Impression: I’m biased, but I love this beer. I’ve been drinking the heck out of this!
What’s Next With This Recipe?
I want to try two things – one is maybe a little less bitterness. The other is honey instead of sugar. I’m wondering if some Orange Blossom honey would work well with the citrus based hops.
