Overview
- A 100‑milliliter bottle of Dassai's space‑brewed sake sold to an anonymous buyer in Tokyo for 110 million yen, or about €587,000.
- Dassai and Mitsubishi Heavy Industries sent brewing gear and ingredients to the International Space Station to run a controlled fermentation test.
- The mash fermented in November 2025 under conditions that mimicked the Moon’s weaker gravity at roughly one‑sixth of Earth’s pull.
- The 260 grams of mash splashed down in the Pacific on February 27 and were processed in Japan into 116 milliliters, with 16 milliliters used for tastings and 100 milliliters auctioned.
- Dassai reported a distinct acidity and said the experiment proves brewing is possible in lunar gravity, with proceeds reported for future Japanese space projects and a stated aim to build a Moon brewery by 2050.
