Complex Micro(?)-Biological System (CommuBioS) studies the aging of complex multicomponent liquids during long-term storage in space. It stores samples of wine, a chemically complex liquid, on the space station and compares the samples with those stored in an aging facility on the ground to determine the effect of the space environment on specific components. Results advance knowledge of the evolution of compounds that are critical for the nutrition and taste of foods. Image courtesy of: NanoRacks
