Space Beer may Taste better than Earth
Beer. đŸȘđŸș

The University of Florida’s Institute of Food & Agricultural Sciences first experimented with making beer in microgravity. Their results, indicate microgravity may not only speed up fermentation processes, it may also produce higher quality products.

Researchers were able to confirm one of their initial hypotheses that microgravity doesn’t appear to harmfully affect fermentation. What’s more, the fermentation process actually sped up in the clinostat samples as compared to their controls. But there was one additional, unexpected result (microgravity yeast may allow for even higher quality products than simply fermenting here on Earth). Although further investigation is needed, researchers think this might relate to a particular gene in yeast that oversees the levels of ester (fermentation byproducts responsible for both good and bad beer flavors).
