Ninkasi Brewing’s latest beer: Ground Control. Last year, the brewery sent six vials of brewer’s yeast into space (77.3 miles up)—this was their second attempt to do so—and brought them back to brew up this Imperial Stout. Brewed with Oregon hazelnuts, star anise, cocoa nibs, and some astro-yeast, Ground Control is a full and flavorful stout. It will be available in select markets on April 13.
“Compared to modern beers, the shipwreck beers contained similar levels of potassium but 15- to 60-fold more sodium, presumably derived from sea water. This may have diluted the beers up to 30%,” the scientists wrote in the paper published in the Journal of Agricultural & Food Chemistry.
“Ethanol contents were low (2.8-3.2%) compared to typical modern lagers and ales. The mass ratios of glycerol and ethanol were 4.5% for both shipwreck beers, which is typical for a yeast fermentation product.”
Dr Gibson and his colleagues analyzed samples from two bottles recovered in the shipwreck.
They determined that the samples were different beers based on their hop content.
