Hop BroMahou Brew in Naha, Okinawa, unveiled a new release on March 4, "Hammer Krushed Brain #2"! The style is Triple IPA, and it's 10.0% ABV too.
MugiWhoa, 10%!? That's basically a final boss wearing a beer costume!
Hop BroIt really does have final boss energy. Batch 0065, IBU 80, FG 1.010, SRM 4. It's firmly bitter, but the appearance is fairly bright.
MugiHold on, don't suddenly turn this into a test on FG and SRM!
Hop BroFG is a rough guide to the residual sweetness left after drinking, and SRM is the color depth. In other words, it looks bright and drinks crisp, but the hops are super powerful!
MugiOh wow! Fresh-looking on the outside, but it hits hard on the inside! A gap-moe beer!
Hop BroAnd the hop design is dense too. Strata and Krush Cryo are dry-hopped in two stages, during and after fermentation, plus DynaBoost Citra during fermentation and HyperBoost Mosaic after fermentation. It's built to layer citrus, tropical, and dank notes.
MugiWhat is that! The hops aren't just the four heavenly kings, they've brought backup too! What does "dank" mean, does it sink?
Hop BroNo, no sinking. "Dank" means a resinous, deep aroma. It is inspired by Ise Kadoya Beer’s Triple IPA recipe, but reworked in Mahou Brew’s own style, which is pretty exciting.
MugiIn Tsuboya, where yachimun culture lives on, such a bold beer... precious! And since it's high ABV, I want to drink it slowly while following how the aroma changes with temperature! Hop bro, let's crack this open tonight!?
