My guess is you are correct. the micro brewery in the states will carrry a ipa, a blonde pilsner, and a stout/ ale.
In particular supermarkets tend to only carry one stout, not sure if that is some sort contractual thing with Guinness or what. Might just be a matter of popularity
We have only been able to get beer in super markets for ~3yrs I would say we have 3-5 stouts from the local then all national brands are 5% flavoured water
