Low-gravity lager
Question: Apparently NASA is aiming to brew a beer in space. The yeast can
neither sink nor rise as in traditional beer production and any carbon dioxide
that is produced will not rise to the surface. So how will the beer ferment and
will the final product be anything like Earth beer?
Answer: NASA is indeed interested in the questions raised by brewing beer in
a microgravity environment. Scientists who study the physics of gas-liquid
mixtures would like to understand, for example, what happens when there is no
buoyancy to bring the bubbles to the surface of a…
