The interview with Matt that I saw, he describes the recipe as the same as Union Jack however the yield was 35/55s of the Union Jack yield; And dry hopped 4 times with possibly a little different hop schedule.
I reworked the grain bill to reflect the yield ratio as above and recently brewed a batch.
The first runnings we 1.090 which yielded 3 1/3 gallons. My second runnings looked pretty strong compared with normal sparge output. Forgot to take a post boil reading.
Pitched 2 cups of harvested yeast (safale 05) from a recent Pliny batch. My fermentation chamber smells wonderful! Changed the 90 minute addition to 1 oz of Warrior and one of Centennial. Will report back in a month on the results.
Here is my recipe:
