Is there a BeerAdvocate-like ranking of beers commonly found in supermarkets? Is there a ranking of beers (maybe by country) you can actually find in a supermarket?

I know the BeerAdvocate one, but it seems I would need to sell my soul to get any beer in the top 250.
You can check out the top rated beers at the user ratings site Untappd.

You can filter by style and country, and the app is very easy to use. I'll bring it up on my phone when I'm at a restaurant or grocery store and I want more info about a beer I haven't seen before or to check out the ratings.
