Yeah, I am not sure what I would suggest as a strategy.
Anchor Christmas Ale is a unique beer that a lot of beer geeks around the country would seek out. I would often pick up a 6-pack when I saw it for sale. Keeping that in the rotation for national distribution seem wise.
I am not sure what strategy will work for Anchor Steam. It probably has enough popularity for national distribution, but it might also be an outdated product that will struggle nationally (like it seems to have done on the past). They could just double down on it being a Bay-area unique beer.
Outside of tap room and local sales, I am not sure that Anchor should go hard on standard lagers or hazy IPAs (which it seems like the direction they were moving). Was their "California Lager" brewed with the same yeast as Anchor Steam? I could see some market for a few beers (Pale Lager, Hoppy Lager, Cold/West Coast IPA, Blonde) made with their house 'lager' yeast.
Anchor Porter was a fav of mine that I would like to see back in distribution (same for Sierra Nevada Porter). I have not had Liberty Ale in a while. Is there a huge market for a 5.9% Cascade hopped Pale Ale these days? Maybe locally, but likely not nationally.
