It's actually not the same PBR that we drink here:

"I still like formulating specialty beers. In fact, with Pabst, I just made the first specialty beer in Mainland China. There’s almost no ale in China: I had to smuggle the yeast into the country. I formulated a special high-gravity ale called “1844.” It’s all malt, and we use caramel malts from Germany. The initial aging is dry-hopped rather heavily. Then we do a secondary aging in new uncharred American oak whiskey barrels. We bought 750 brand new barrels to the tune of $100,000. This is a very special beer; it’s retailing for about over $40 U.S. for a 720 ml bottle."
