Hop BroAt 3TREE BREWERY in Ibaraki, the sour '903 (Kumasan)' is on tap. It's a Hokkaido-themed beer, and the name alone already makes you curious, right?
MugiWait, 903 is read as Kumasan!? It's suddenly cute even though it's a number, and my brain can't keep up!
Hop BroWhat’s cool is that it's a beer inspired by Hokkaido's carved wooden bears, and they even add guarana during the brewing process.
MugiDuring the brewing process? So they don't flavor it afterward, but add it from the start? This is starting to feel like a beer class!
Hop BroExactly. Since it's added while brewing, the ingredients meld together instead of it just tasting sweet. And they've really worked the reddish-brown color into the design too.
MugiWow! It's cute to look at, and it even gives off that carved-bear vibe. It's the kind of thing that makes you want to take a photo before even drinking it!
Hop BroThey use five types of malt for the color, and that caramel-like sweetness also comes from the malt. For a sour, the design is pretty detailed, right?
MugiWait, malt does that much!? It's not just floury grain stuff, it's like a master of the flavor foundation!
Hop BroOn top of that, they layer in sweet clove-like aromas and finish it off with a lemon-like acidity that snaps the aftertaste into place. It's very 3TREE not to make it sweetness all the way through.
MugiI see, so it's not just cute, it actually has real drinking depth too. It kind of feels like you can see the maker's face behind it, which is nice.
Hop BroBecause it's a brewpub where they brew on the first floor and you drink on the second, it feels especially fresh. If you want a sour in Ibaraki, this is definitely a beer worth remembering.
MugiI can't take it anymore, just hearing about it makes me want to drink it! I want to go meet the bear right now at the beer stand on the second floor!
At 3TREE BREWERY in Futabacho, Ibaraki City, Osaka, the sour beer '903 (Kumasan)' is on tap.
The shop is a brewpub with brewing equipment on the first floor and a dining space on the second. According to its official website, it offers four beers in total, including its standard saison and pale ale plus a monthly limited beer, and the latest information is shared on social media depending on brewing and business conditions. Its compact layout also makes it easy to stop by on the way from the station.
The featured beer, '903 (Kumasan)', is a sour-style beer that 3TREE BREWERY holds dear. It is a beer themed around Hokkaido and its carved wooden bears, and the name is written as "903" but read as "Kumasan." The flavor concept was born from the idea of recreating Hokkaido's local Hakodate cocktail "Garabee" as a craft beer. Instead of mixing in guarana afterward, it is added during the brewing process, which lets the guarana's distinctive character come through clearly in the beer.
Its color is reddish-brown. To create the carved-bear-inspired appearance, five kinds of malt are used, and the caramel-like sweetness associated with a guarana drink is expressed through the malt as well. Sweet clove-derived aromas are layered on top, and a lemon-like refreshing acidity sharpens the finish. Rather than leaning only toward sweetness, it keeps the clean contours typical of a sour beer, which is especially striking.
It is a glass crafted with balance in mind so that even people who are not very familiar with craft beer can approach it easily, while also carefully shaping a theme that the brewery feels deeply attached to. Being able to enjoy it at the beer stand on the second floor, at a distance where you can see the brewer's face, is also part of what makes 3TREE BREWERY feel like 3TREE BREWERY. When you want to drink a sour beer in Ibaraki, this is one to remember.
