This is Important! Students Are Figuring Out How to Make Beer on the Moon

When human being colonize other Solar bodies, how will they see to their basic needs? Already, research has been performed to determine where colonists would be able to procure water, how they might grow their own food, and where and how they might live. But what about the finer things in life, the things that make all the hard labor and sacrifice worth it? In case it’s not clear yet, I’m talking about beer!

If and when Lunar or Martian colonies become a reality, will the colonists be able to brew and enjoy their own beer? Or will imported beer be the only thing available to them? That’s the question a team of bioengineering students from the University of California San Diego sought to answer. As finalists who competed in the Lab2Moon competition being held by TeamIndus, they combined their love of beer with their love of space exploration.

As the only Indian team in the Google Lunar XPRIZE competition, TeamIndus has been working on a privately-funded spacecraft to send to the Moon. Once complete, TeamIndus hopes to conduct a soft landing on surface of the Moon later this year. Their accomplishments so far include being one of the five teams selected to compete in the Milestone Prizes and successfully winning the $1 million Milestone Prize for their landing technology.

The Lab2Moon competition was held in order to see a youth experiment brought to the Moon aboard that spacecraft. And while their experiment did not take home the top prize, their final prototype will still be going into space. Thanks to Synergy Moon, who won an XPrize verified launch contract, the experiment will be launched aboard a rocket this December (the planned launch date si currently Dec. 28th, 2017).

For the sake of their experiment, the UC San Diego team – all undergraduates with the Jacobs School of Engineering – sought to test if yeast would be viable in a Lunar environment. As the key ingredient in the production of beer (and many other beneficial things), thieir experiment sought to determine if Lunar colonists will be capable of becoming their own brewmasters.

Their team name is “Original Gravity”, a delicious pun that alludes to both brewing and the Lunar conditions they are investigating. In the case of brewing, Original Gravity (OG) is the measure of sugars dissolved in the wort (the beer before it is fermented). In the case of the Moon, it refers to the fact that Lunar gravity is just 0.165 times that of Earth’s, which could affect the behavior of the microorganisms like yeast.

As Neeki Ashari, a fifth year bioengineering student and the team’s PR & Operations Lead, said in a University press release:

“The idea started out with a few laughs amongst a group of friends. We all appreciate the craft of beer, and some of us own our own home-brewing kits. When we heard that there was an opportunity to design an experiment that would go up on India’s moonlander, we thought we could combine our hobby with the competition by focusing on the viability of yeast in outer space.”

With sponsorship from the Omega Yeast Labs, the team designed a unique brewing system. First, all the prep work that precedes the adding of yeast – for instance, combining malted barley and water to create wort – would take place on Earth. Second, the team plans to combine the “fermentation” and “carbonation” phases – which are usually done separately – into one phase.

This process makes for a system that is much easier to design, eliminates the need for releasing accumulated CO² (which can be a hazard) and also prevents the possibility of over-pressurization if anything in the system fails. Last, the testing of fermentation will not rely on density measurements which rely on gravity (as brewers do on Earth), instead using pressure to determine sugar content.

As Han Ling, a fifth year bioengineering undergraduate student and the team’s leader, explained, “Converting the pressure buildup to fermentation progress is straightforward, as long as volume and original gravity – specific gravity before fermentation, hence our name – are known prior to the experiment.” Measuring roughly as wide as a soda can, their system is able to ferment yeast and worst to create beer, even under Lunar conditions.

In addition to being the first ever experiment to brew beer in space, their experiment will be also be the first to craft beer using such a small apparatus. A Srivaths Kaylan, a fourth year nano-engineering major and the team’s mechanical lead, indicated:

“Our canister is designed based on actual fermenters. It contains three compartments—the top will be filled with the unfermented beer, and the second will contain the yeast. When the rover lands on the moon with our experiment, a valve will open between the two compartments, allowing the two to mix. When the yeast has done it’s job, a second valve opens and the yeast sink to the bottom and separate from the now fermented beer.”

Looking to the future, Ashari and the team hope to see their experiment adapted for use on other planets – like Mars! Other proposed experiments that were entered in the competition included methods for photosynthesis to producing electricity in a Lunar environment.  Beyond making beer, understanding how yeast will became in a Lunar environment is also important in the development of pharmaceuticals and yeast-containing foods, such as bread.

It certainly is interesting to think about what kind of beers could be produced in an extra-terrestrial environments, isn’t it? Will future generations of brewers have the option of using locally-grown barley, wheat, hops, and yeast cultures to craft their beer? Will the use of Lunar or Martian water have an affect on the beers taste?

And then there’s the matter of names and styles. Will Lunar brewers create a Dark Side of the Moon Stout? Will the people of Mars specialized in Red Ales? Like I said, interesting!

‘Space Beer’ Available for Purchase to 250 People

The wait is finally over for those who have been wanting to enjoy a tipple of Sapporo’s “Space Barley” beer, a beer brewed from space-grown barley. Until December 24th, Sapporo will have an online lottery for orders of a six-pack. 250 people will be chosen from the lottery, and allowed to purchase the beer. As with everything flown into orbit, space beer isn’t cheap though: the six-packs will run 10,000 yen apiece, which converts to about $110, or almost $19 a bottle.

This is the second lottery that the Japan-based Sapporo has held for access to the beer, though last time around there were only 60 people chosen to taste the beer. The name of the beer really says it all – Space Barley beer is made from barley descended from the barley grown on the ISS during a 5-month experiment back in 2006. That original barley isn’t still being used, though: the current brew is made from the fourth generation of the stock grown on the ISS.

Sapporo teamed up with a researcher from Japan’s Okayama University, Manabu Sugimoto, who has been taking part in a Russian study to grow edible plants in space. Peas, lettuce and wheat have all been grown and harvested in space as well. Barley was chosen because it is a rather hardy plant that will grow in a variety of environments at a range of temperatures. Sapporo made it into beer because, well, what else are you going to do with leftover barley from space?

If you think that the beer will taste different, think again: Sapporo spokesman Yuki Hattori said Monday, “Some people may expect the space beer to taste very different, but its selling point is that it’s the same.” It shouldn’t taste any different indeed, given that an analysis of the DNA from the barley grown on the ISS showed no difference from plants grown right here on Earth.

Ian O’Neil had the brilliant idea of using recycled space urine from the ISS to make the space beer more “complete.” If that were the case, though, I’m sure the company wouldn’t have had over 2,000 people enter the lottery by last Sunday. If you want to get in on the orders, you might have to be able to read Japanese. The only link I could find to the internet lottery is in Japanese.

Though it may be a bit of an advertising gimmick, the proceeds from this latest sale of Space Barley will all go to Okayama University with the aim of promoting children’s education and space science research.

Hopefully between now and the fifth generation brewing of this beer, the ISS can grow some space peanuts to go along with the drink, or at least use some of the harvested wheat to make some space pretzels shaped like little stars.
