HOTARU
- Style: Farmhouse Ale with Sumomo and Kaffir Lime Leaf
- ABV: 5.0%
- IBU: 11

MANGOSTEEN HOKUTO in Hokuto, Yamanashi, introduced a new beer called HOTARU on July 15. The farmhouse ale uses a large amount of Yamanashi-grown Oishi plums and kaffir lime leaf, creating a saison with bright fruit acidity, a tropical citrus character, and yeast-driven complexity.

According to the caption, the beer is based on a recipe originally brewed two years ago as a TYU anniversary beer in Iwata, Shizuoka. The brewery had wanted to make it again every year, but the timing did not work out last year. This time, after close coordination with plum grower Watanabe, the release finally came together.

The plums were harvested at full ripeness while still on the tree, rather than being ripened after picking. That made them sweeter and fresher, but also soft and sensitive to vibration, so transport required extra care. Even the drive home reportedly filled the car with the scent of plums, underscoring how central the fruit is to the beer.

As a brewery based in Hokuto, Yamanashi, MANGOSTEEN HOKUTO continues to build beers around local agricultural ingredients. HOTARU is another example of that approach, and sales were directed through the link in the profile.
