Drs. Philip Wietstock & Brian Gibson discuss the Gas Hopper - a CO2-based method to infuse hop aroma into beer without dry hopping. They compare brewing techniques between Germany and the US, explore hop extract usage, and highlight the versatility of the Gas Hopper in modifying beer flavors. The podcast also covers the efficiency and sustainability of using CO2 in brewing, the optimization of aroma transfer with the Gas Hopper, and the potential applications beyond hops in beverages.
