There is a mark on Torrance now because Yorkshire Square Brewery has become only the second brewery in all of California to have the Cask Marque affixed to their brewery.
Cask Marque’s Certificate of Excellence “recognizes the high standards necessary for a great cask ale program so that beer drinkers can know that a particular establishment is a likely site for the sublime experience for which proper cask ale is held in high regard.” The brewery is checked twice a year to make sure they stay up to snuff.
