Yeah, for their Miller Genuine Draft- I assume their other beers are pasteurized.
A-B used to have a Bud Draft recently, didn't they? (There was a big "real draft" fad in the 60's and another in the 90's as I recall.) I'm guessing that was cold-filtered. (Altho', confusingly, there *were* beers sold as "real draft" that also proclaimed "pasteurized" on their labels- who knows WHAT was going on with them.)
But Coors has for many years cold-filtered their "Coors Banquet Beer" or whatever they call it these days- that's why they used to demand that retailers refrigerate their beer, why they claimed all their beer was shipped cold, etc. It's also the source of the legend that Coors beer used asbestos to filter their beers. IIRC the Enzinger filters were originally developed in Germany and Coors began using them in the 50's (many years before either "real draft" eras) and were made of cotton and asbestos in the beginning.
