Since two good cheese shops are within easy driving distance, I usually don't bother to look at the cheese bins when sent to the local groceries, but when my wife goes she always brings back slabs of Colby and Monterey Jack which I find bland but acceptable.
I was wondering what cheeses you might find at the ordinary corner grocery or chain stores (not upscale grocers like Trader Joes or Whole Foods) that are better than acceptable. I'll start it off with two:
Cabot cheddars are better than average, particularly the ones in the wax wrappings.
St. Andre at groceries seems to be almost as good as the kind I buy at cheese stores.
