I always liked actual Molson Canadian from Canada with the proper alcohol content. The Americanized version was bleh.
Going to the other border, Tecate is good if it’s cold and salted. Far better than Corona.
if you like Tecate, try their better beers made by the same company:
Dos Equis Amber
Dos Equis Lager
Sol (light beer)
These are Mexican beers made in the German tradition of making lager beers. They are sold in my area in mixed 12 packs. They also throw in a seasonal Bock beer in the late fall.
I had heard the fruit in the top of the Corona bottle was to keep insects out but I found it helped make the beer less undrinkable.
Cheers,
Jim
