UCSF Brewers Guild on Spectrum

Tune in Friday, September 7th @ noon as Spectrum features members of the UCSF Brewers Guild.  They will discuss the science of beer making.  What are the chemical changes that happen as grains are malted, kilned, roasted, and boiled?  How do compounds in hops change to alter the flavor and aroma of beer?  Is water chemistry important?  What kind of data do trained biologists take as they make a batch?
