Kofu's diagonal just tapped NEW Onigashima IX from Y.Market Brewing. It showed up in the July 30 Instagram post, and that's the kind of update I can't scroll past.
Mugi
Wait, that name alone sounds like a boss battle! What kind of beer is it?
Hop Bro
It's an 8.0% Hazy IPA. A guest beer from Y.Market Brewing, and the whole point is big aroma pulling you in.
Mugi
Whoa, but what is Hazy IPA supposed to mean? It suddenly sounds like I'm studying for chemistry.
Hop Bro
Put simply, it's a cloudy style IPA. It looks hazy, and instead of sharp bitterness, it leans into aroma and juicy drinkability.
Mugi
Ohhh, so tropical aroma means my brain is already on a beach before I even take a sip?
Hop Bro
Pretty much. The article also says it has fresh citrus character, so you get that lush mango-like body with a brighter orange or grapefruit lift.
Mugi
What is this, a fruit parade? And it's the Noboribetsu Beer collab series too, right?
Hop Bro
Exactly. This is the ninth release in the NEW Onigashima series, brewed year after year, so the name carries some real weight now.
Mugi
Okay, but when they say guest beer, does that mean it's like a visiting all-star instead of the pub's usual lineup?
Hop Bro
That's basically it. You really see the tap list personality in choices like this, and honestly, this kind of limited pour already has me wanting a glass.
Mugi
Then it's settled. Whether it's a first pour or a slow sipper, I want this in Kofu immediately!
