In an innovative blend of traditional brewing techniques and advanced space science, Japanese sake brewer Asahi Shuzo is poised to ferment sake aboard the International Space Station (ISS) in 2025. This ambitious initiative, titled “Dassai MOON – Space Brew,” aims to send essential sake ingredients, including Yamada Nishiki rice, koji mold, yeast, and water, to the ISS’s Kibo module, where fermentation will take place in microgravity conditions.
This groundbreaking experiment seeks to examine how fermentation processes differ in space compared to Earth, potentially paving the way for the development of beverages and foods suitable for long-duration space missions. The resulting unrefined sake (moromi) will be frozen and returned to Earth, where Asahi Shuzo plans to market this extraordinary product for approximately $650,000. All proceeds from sales will directly fund Japan’s ongoing and future space exploration efforts.
Amusingly, this project echoes the classic astronaut joke: “Where do astronauts go for a drink? The space bar!” While alcohol consumption aboard the ISS is restricted due to safety and regulatory concerns, Asahi Shuzo’s endeavor is rooted in scientific exploration rather than recreational purposes, offering vital insights for future extraterrestrial living.
Ultimately, the project aspires to lay the groundwork for lunar brewing, potentially harnessing lunar resources to support human activities on the Moon by the 2040s. Asahi Shuzo’s pioneering efforts thus symbolize not only a novel brewing method but also a significant cultural and scientific advancement toward humanity’s extended presence in space.

This is such an interesting blend of culture, science, and innovation. I love how Asahi Shuzo is taking something deeply rooted in tradition and launching it into the future by testing fermentation in space. It’s super cool to think about how microgravity could affect something like microbial fermentation. It also makes me wonder what kinds of changes in flavor, texture, or even alcohol content might result from brewing in space.
Since microbial activity is influenced by gravity, temperature, and pressure, it’s possible the yeast and koji mold could behave differently in orbit—maybe producing unique flavor profiles we’ve never experienced before. Even the way bubbles form and rise during fermentation could change, potentially altering the mouthfeel or aroma of the final product. It’s interesting to think that sake could take on a whole new profile just by being brewed in a different environment.
