Explore space-aged beer experiments – from ISS fermentation to Mars barley, discover how brewers test microgravity brewing creating out-of-this-world beers in 2025.
Could beer brewed in space taste different than Earth beer? Tracking brewing innovation while analyzing space experiments, I’ve explored space-aged beer experiments through ISS fermentation studies, microgravity yeast behavior, and orbital ingredient testing transforming brewing’s final frontier. These cutting-edge projects using home brewing equipment principles demonstrate how space conditions affect fermentation.
Understanding space-aged beer experiments matters because microgravity affects yeast behavior, carbonation, and flavor development while advancing food production technology essential for long-duration space missions. According to Starbase Brewing’s MicroBrew-1 project, world’s first experiment ferments beer in space where wort and freeze-dried yeast combine in microgravity studying top fermentation’s gravity dependence.
Through my systematic analysis of space brewing including Starbase’s ISS experiments, Japan’s Isekado Space Brewing Project, and Budweiser’s barley research, I’ve learned how orbital conditions transform brewing. Some approaches prove remarkably innovative studying fundamental fermentation science, others focus on ingredient development, and several demonstrate how space brewing advances both exploration and terrestrial applications.
This guide explores seven space brewing experiments, from ISS fermentation to ingredient testing, helping you understand how microgravity research transforms beer while supporting long-duration space missions requiring sustainable food production.
Starbase Brewing’s MicroBrew-1 ISS Experiment
The NASA Crew-11 mission launched first space fermentation. According to Payload Space coverage, Starbase Brewing founder Nate Argroves and Jaguar Space founder Luis Zea partnered on ISS experiments flying July 31, 2025 with big implications for future space explorers.
The MicroBrew-1 design enables microgravity fermentation. Tubes containing wort and freeze-dried yeast in separate chambers require astronaut cranking combining them setting off top fermentation typically relying on gravity.
The top fermentation process proves gravity-dependent. According to Factories in Space database, first beer fermentation study in space where yeast and wort mix in microgravity enables studying gravity-driven process implications for future bioprocesses.
According to Starbase’s brewing page, MicroBrew-1 project launching on NASA’s Crew-11 mission represents world’s first experiment fermenting beer in space.
I find this experiment’s fundamental science approach fascinating. Rather than simply sending ingredients to space, actually fermenting in microgravity conditions provides data impossible to replicate on Earth revealing fermentation’s gravity dependence.

The Kibo module hosts Japan’s first beer fermentation. According to Tokyo Weekender’s coverage, Mie-based craft brewery Isekado collaborates with Takazago Electric conducting Japan’s first-ever beer fermentation experiment aboard ISS.
The proprietary yeast selection proves crucial. Isekado dispatching award-winning yeast strain into orbit with fermentation occurring in bespoke vessel engineered by Toyo Seikan Group Holdings withstanding pressure and temperature fluctuations.
The space-cultured yeast returns for Earth brewing. According to Asia Brewers Network, research team analyzes how space conditions altered yeast’s fermentation behavior with resulting “space-cultured yeast” brewing limited batch.
According to Tokyo Weekender, Kirin Brewery provided technical cooperation showcasing Japan’s collaborative spirit.
The crowdfunding approach democratizes participation. Contributors through Campfire platform receiving limited-edition space-brewed beer as reward assuming project succeeds creates public engagement with space research.
Budweiser’s Multi-Mission Barley Research
Four ISS missions studied barley for Mars brewing. According to Smithsonian Magazine, December 2017 Anheuser-Busch InBev had SpaceX rocket transport 20 barley seeds to ISS conducting seed exposure and germination experiments.
The long-term Mars goal drives research. According to ISS National Lab, experiment uses miniaturized automated malting system comparing barley malted in space with ground controls.
The water scarcity concern motivates preparation. According to Smithsonian, satellite imaging confirms vast glaciers below Mars rocky surface though mining, thawing, and purifying creates extraordinarily limited raw material.
According to American Craft Beer, 2019 Anheuser-Busch sent barley seeds to ISS studying how space-grown barley differs from Earth-grown counterpart.
The Mars brewery ambition proves audacious. Budweiser announcing goal becoming first beer of red planet demonstrates long-term vision though technical and logistical challenges remain substantial.
OASIS: Barley Growth in Mars Soil
The simulated Mars regolith tests agricultural viability. According to Payload Space, OASIS attempts growing barley aboard ISS in simulated Martian regolith adding spent grain from brewing supporting crop growth.
The nutrient cycling proves essential. Spent grain from beer production providing organic matter and nutrients demonstrating closed-loop agricultural systems necessary for sustainable Mars colonization.
Texas A&M Agrilife collaboration adds expertise. According to Payload Space, university working with brewery on Earth-based research two years brings agricultural science expertise to experiment.
According to Starbase Facebook, biggest update ever announces brewing first ever beer in space.
I appreciate this experiment’s practical focus. Rather than purely scientific curiosity, demonstrating actual agricultural production in Mars-like conditions addresses critical survival needs for long-duration missions.
Historical Space Yeast Experiments
Ninkasi’s 2015 Ground Control used spacefaring yeast. According to American Craft Beer, Ninkasi Brewing Company released beer made from brewers’ yeast sent into space creating first commercially available space-influenced beer.
The 77.3-mile altitude journey tested yeast viability. According to Ninkasi’s lab article, brewed with yeast that traveled to space and back sharing beer with space and beer nerds alike.
Rhinegeist’s 2025 Apex Apple Ale used rocket-launched yeast. According to Phys.org, Cincinnati brewing company producing 16 kegs from yeast University of Cincinnati rocketry team fired into high altitude.
According to UC News, rocketry team sends yeast 2 miles high for new apple-flavored ale demonstrating university-brewery collaboration.
The space-adjacent experiments prove more accessible. While full orbital missions require substantial resources, high-altitude balloon and rocket launches enable smaller breweries participating in space brewing creating unique marketing stories.
Microgravity’s Brewing Challenges
The bubble behavior transformation affects carbonation. According to American Craft Beer, microgravity prevents bubbles rising to surface potentially causing flat or unevenly carbonated beer.
The yeast-sugar interaction changes fundamentally. Without gravity drawing liquids to stomach bottoms leaving gases at top, astronauts produce wet burps complicating beer consumption.
The fermentation vessel engineering proves critical. Designing specialized fermentation vessels handling unique space conditions including pressure management and temperature control without gravity-driven convection currents.
According to American Craft Beer, yeast might behave differently potentially altering flavor and alcohol content requiring genetic modifications performing better in microgravity.
The fundamental physics challenges inspire innovation. Understanding how fermentation works without gravity advances both space brewing and terrestrial bioprocessing improving Earth-based applications.
Future Space Brewing Developments
