KURAND Inc. will be selling a limited quantity of original sake, “Kyodai Rikei No. 54 Re,” a collaboration between Koyori Hakui of the Hololive VTuber unit [Kessha Himitsu holoX] and the sake brand “Kyodai Rikei,” starting at 8 PM on Saturday, May 30, 2026. The sake will be sold through the online liquor store “KURAND.”
This product is an improved version of the previous release, “Brothers Science No. 54,” which came out in 2022. The previous release was so popular that it sold out in just about 3 minutes after its initial release. For this “Brothers Science No. 54 Re,” Hiroe Koyori herself has carefully selected the sake rice and yeast based on the data that Brewery Ariga has accumulated. It has been updated with an uncompromising approach befitting a researcher, further pursuing the “dry yet fruity” taste that she desires.
This sake is manufactured by Ariga Brewing Co., Ltd. in Fukushima Prefecture. It is classified as a Junmai Daiginjo sake, using Gohyakumangoku rice. The rice polishing ratio is 40%, the yeasts used are F7-01 and 701-15, and the alcohol content is 15%. The volume is 720ml, and the selling price is 8,910 yen (including tax).
The sales period ends on June 21, 2026 (Sunday) at 23:59. Due to limited quantities, sales will end once the available quantity is reached. Shipping is scheduled to begin sequentially from mid-August 2026.
