A French brewery named Hoppy Urban Brew has an extensive line of craft beers, and now they have one in a lovely shade of blue! The beer called Line is made blue by the algae spirulina, which produces the chemical phycocyanin. The algae is grown by Etika Spirulina, a French company promoting algae as a dietary supplement. The brewery adds phycocyanin to its craft beer to turn it blue. Those who know say the algae adds only color to the beer, and it does not taste any different when phycocyanin is added. The collaboration between the algae firm and the brewery has paid off well so far, with the distinctive blue beer drawing a lot of interest.
