Hiruzen Brewery Tsuchi to Mizu releases Vintage Ale V-10
Hiruzen Brewery Tsuchi to Mizu in Maniwa, Okayama, has released Vintage Ale V-10. The new beer is a sour ale matured slowly in oak, reflecting the brewery’s nature-driven approach in the Hiruzen district.
Hop BroToday I want to talk about Hiruzen Brewery Tsuchi to Mizu, because they just released a limited vintage ale called V-10.
MugiWait, V-10 sounds like a robot model number. That’s a beer?
Hop BroA very real beer. It’s a 2025-brewed vintage ale, sold in 750ml and 375ml bottles, and it comes in at 8% ABV.
MugiWhoa! But when I hear lactic fermentation, I feel like a science class is about to start.
Hop BroIt sounds technical, but it’s basically a blueprint for gentle tartness. It gives you a lemony, yogurt-like edge instead of rough sourness.
MugiWhat is that! So the oak barrel aging part means the beer goes into a wooden room and comes out all refined?
Hop BroHonestly, that’s not far off. Slow aging adds woody nuance, smooths out the acidity, and helps the malt and coriander seed come together.
MugiThat’s so cool. And they use Hiruzen spring water plus native yeast collected in the village? That’s like brewing the whole landscape.
Hop BroExactly. Their whole identity is life with farming: organic-minded ingredients, natural cultivation, and the feel of Hiruzen built right into the beer.
MugiSo instead of big flashy hops, this is more about flavor built by time. Why do I suddenly feel more sophisticated?
Hop BroThat’s the appeal. V-10 has a quiet presence that sneaks up on you, and talking about it is already making me want to pop one open.
MugiThen it’s settled. I’ll start with 375ml, move up to 750ml with company, and right now I want a glass!
Vintage Ale V-10 arrives
Hiruzen Brewery Tsuchi to Mizu, based in Hiruzen Chuka, Maniwa City, Okayama, has released Vintage Ale V-10. Retail listings describe it as the 2025 vintage, available in 750ml and 375ml bottles.
At the center of the beer is a process built around lactic fermentation and slow maturation in an oak foeder. The beer is presented as a sour ale, with an alcohol content of 8%. Listed ingredients include malt, hops, and coriander seed, and retail information notes an organic-leaning ingredient profile.
A beer shaped by its place
Tsuchi to Mizu brews in a small, nature-rich community in northern Okayama. According to the brewery’s own information, it uses natural water from Hiruzen and wild yeast collected in the local settlement, while working with naturally grown and organic ingredients. The brewery’s Instagram describes its philosophy as brewing beer “occasionally” as part of a life centered on farming and the land.
That background makes the Vintage Ale series especially representative of the brewery’s style. The interplay of oak, acidity, and long aging should appeal to drinkers who value beers that evolve over time rather than making a quick impression.
