Anchor actually did have a bunch of more modern beers after the Sapporo acquisition, but they were only available at the taproom. They only had retail distribution for the old reliable flagships (and then had a rebranding that was not well received).
Yeah, that was the weird thing. I visited their tap room a few times here and there (I live fairly close), and some of their selections were truly different and interesting and good. But you couldn't get them anywhere else. Meanwhile, I hardly ever go for an Anchor beer when in a bar, as there are always more interesting choices. I wouldn't call myself a beer connoisseur, even. Seemed like shooting themselves in the foot.
