Bijofu Yuzu (720 ml)

Hamakawa Shoten, registered in 1904 in Tano-cho on Kochi's narrow Pacific coastal strip, built its reputation by mastering ultra-soft nansui water drawn from the subterranean Nahari River — a water type once dismissed as unworkable for quality brewing. That same water forms the backbone of this yuzu expression, its near-zero mineral hardness allowing the aromatic oils of yuzu to project without interference from dissolved salts or hardness compounds.

Kochi Prefecture is Japan's foremost yuzu-producing region, and the fruit's characteristic tart, pithy citrus intensity — sharper and more resinous than sudachi or kabosu — is the defining aromatic axis here. The brewery's house yeast tradition (AA-41 and CEL-24, both isoamyl acetate-forward) shapes the fermented base toward melon and soft citrus, creating a layered backdrop rather than a flat spirit-and-juice blend.

What separates this from category peers is the nansui water integration: where most yuzu liqueurs built on harder water read as sharp and one-dimensional, the Nahari River softness rounds the yuzu's pithy edges while preserving its volatile top notes — a textural outcome no technique alone can replicate. NV by nature; drink young to preserve yuzu's volatile aromatic lift.
