New release born from a three-way collaboration

The brewery MAHOWBREW in Tsuboya, Naha City, Okinawa Prefecture, has announced a new beer, Nidhogg Luchuensis. MAHOWBREW obtained its liquor manufacturing license on June 24, 2024, and operates in Tsuboya, a place where a spirit of “making things” runs deep, producing distinctive beers.

This new release is a collaboration beer brewed in the Norwegian Sour Red Ale style. It is listed at 6.0%, 17 IBU, 1.027 FG, and 14 SRM. Sales begin at 3:00 p.m. on April 16.

Norwegian and Okinawan fermentation cultures intersect

According to the product description, this beer was completed through a three-way collaboration with Bygland Bryggeri (Rannei Sake) in southern Norway and Kveik Yeastery, which works with the country's traditional yeasts. MAHOWBREW says the project began when it learned that Bygland Bryggeri makes sake from koji production through brewing, and uses Kveik yeast in that fermentation.

A major feature of the recipe is the use of black koji. Half as much black koji as malt is added, and it undergoes a mash for about 18 hours. In addition, black koji that has been saccharified in advance in a separate vessel and had its enzymes deactivated is added before fermentation, giving the brew added depth. It is finished with French oak chips and aged.

Flavor direction

MAHOWBREW explains that this beer combines citric acid from koji with the acidity produced by Kveik yeast, aiming for the complexity of a Flanders Red Ale. The flavor concept is said to evoke plums and cherries, along with a complex character with earthy notes, creating a beer designed to highlight red-fruit acidity and oak-derived nuances.

This release, from a brewery in Naha, Okinawa, fusing Norway's fermentation culture with black koji, is a beer that strongly reflects MAHOWBREW's experimental spirit, both in style and ingredients.
