DD4D Brewing Releases ‘Key to the Next Door Salty Lemon’ with Seiryu Shuzo
DD4D Brewing, based in Matsuyama, Ehime, released a new collaboration beer, Key to the Next Door Salty Lemon, on June 18. Brewed with sake yeast from Seiryu Shuzo and brightened with Ehime lemon and salt, it is a Fruited Sake Ale.
Hop BroEhime has a fun one today: DD4D BREWING teamed up with Seiryu Shuzo for a new collab beer.
MugiWhat! A brewery and a sake maker together? It's called Key to the Next Door Salty Lemon, and just the salty lemon sound of it already makes me want a sip!
Hop BroThe style is a Fruited Sake Ale. They used sake yeast, then layered in Ehime lemon and a touch of salt for a real Setouchi feel.
MugiHold on, sake yeast? It's beer, but the rice squad is subbing in?
Hop BroExactly. It's the same yeast used in Iyo Kagiya sake, and it brings a white grape aroma while keeping the finish crisp.
MugiNo way, lemon, salt, and white-grape vibes? That's a lot happening, but that lemon-salt combo sounds unfairly good in summer.
Hop BroThat's the trick: the salt stays subtle and gives it a Setouchi-style outline. IBU is 15, so bitterness stays gentle, but 6.0% ABV keeps it satisfying.
MugiThere it is, IBU! Is that like a report card for bitterness? If it's 15, even I can make friends with it.
Hop BroPretty much. With Cascade hops and PILSEN malt, you still get a malty little afterglow, so it doesn't end as just lemony refreshment.
MugiAnd it launched on June 18, with online sales and DD4D shops too? I need to hunt this down right now!
Hop BroThis kind of local collab feels very DD4D. It's basically a glass of Ehime teamwork, and now I really want one.
MugiSame here! Let's chill one tonight and toast with salty lemon magic. Just don't turn my whole drink into a lecture sample!
