Citra®
Citra™ is a special aroma hop variety developed by the Hop Breeding Company (a joint venture between John I. Haas, Inc. and Select Botanicals Group, LLC). It was released in 2007. Citra™ has fairly high alpha acids and total oil contents with a low percentage of cohumulone content. The variety imparts interesting citrus and tropical fruit characters to beer.
- 1 tsp
Irish Moss - last 10 mins of boil (omitted from calculations)
Irish Moss
A dried red-brown marine algae. Fining agent to remove large proteins. Negatively charged polymer attracts positively charged protein-tannin complexes (extracted from grain husks and hops) during the boil. This action is aided by the clumping of proteins in the boiling process. Irish moss settles to the bottom of the brew kettle with spent hops and hot break material at the end of the boil.

Imperial Yeast A01 House
Imperial Yeast A01 House
The best of both worlds, House is clean and allows malt and hops to shine. This strain is extremely versatile and flocculent enough to drop out of the beer quickly. Best used in American IPAs but works well in English style ales. House is clean at cold temperatures with increased esters as fermentation temperatures increase.
Notes
Mash Schedule: 122F 30-min 140F 30-min 158F 30-min 165F 15-min Water: 1 Campton tablet 1.5tsp Gypsum 0.5tsp Cal Cloride Hops: All hops noted as 1min were actually a late addition (15-min) when wort reached 170F. Dry hop done in secondary for a total of 9 days. Fermentation Temp = 62F

FOTM Brewery is in my neighborhood and I've always loved this IPA of theirs and have missed it during the pandemic and wanted to try a clone. I came up with a rough draft recipe and emailed it to them and their brewmaster was kind enough to reply with some suggested adjustments. Very cool! Anyway, come brew day I was shocked to see the mash efficiency I had, the best I've ever had in fact, around 87%. I assumed it was the result of the highly modified Franco-Belges malt and maybe due to the multi-step/longer mash as well. So my OG was above target. However, I was unable to get any American Ale yeast at the brew shop and ended up using Imperial's House strain with is English and has a lower attenuation. Long story short...due to the lower attenuation my ABV came in on target, but my TG was higher than planned. Oh well... So, when I brew this again I'll use an American Ale yeast and recalculate for better efficiency. Nonetheless, the beer is solid and close to the original. I know there are a lot of Sorachi Ace haters out there, but using them as a late addition really allows their lemon aroma/flavor to shine without any of the other flavors (dill, etc.) you hear people complain of with that hop.
