Hop BroSo basically, Kappa no Doburoku from the Basement Brewery Shop is now open for reservations as Kumazawa Sake Brewery's new arrival.
MugiHuh! Doburoku is that cloudy rice brew, right? It's not beer, so why is it part of the Shonan Beer talk?
Hop BroExactly. This one is set for release on April 17, 2026, and the 720 ml bottle is 1,650 yen (tax included).
MugiWhat! And the best-before period is only two weeks? That's so short!
Hop BroThat's because it's a fresh doburoku without heat treatment, so fermentation keeps going and the flavor changes day by day.
MugiWait, so if I buy it, it'll taste different every day!? The fact that fermentation keeps moving is kind of exciting!
Hop BroOn top of that, pickup is only available until April 24, and it's a rare item that's made only once or twice a year.
MugiSo rare! Come to think of it, Shonan Beer is unfiltered and unheated, right? That explains the strong freshness.
Hop BroExactly, and they also have standards like Pilsner and Alt, plus Schwarz and Tsumabiiru (Golden Ale), so it's fun to enjoy the range of fermented drinks.
MugiWow... Now I really want to compare the drinks at the Basement Brewery Shop. My appetite is growing...
Hop BroDrinking in the calm space of the basement while following the changes brought by fermentation is irresistible.
MugiYeah, this is the kind of thing that makes you want to reserve it right now and toast together on release day!
