I can speak Taishan, my parents' dialect, and Cantonese.
To say beer in chinese generally you'd just say Tsingtao ?? (pronounced ching-dow) since it's pretty much the best beer in China, however if you're in some odd place they may favor a local brew like Harbin up north or Pearl near the pearl river area in Guangdong. Beijing has a brand that totally rips off the Tsingtao look and taste but I can't remember the name at the moment, if you know it please put it in the comments.
