I love me some gruyere! And I'm never had a gruyere that I didn't love...until last night. I bought a nice chunk from the usual suspects over at Whole Foods, brought it home, chopped it up, and BLECH!!! It tasted really bad.
I noticed that the rind was crumbly when I cut it. Pieces looked like dirt. And the taste was really different in some spots, maybe earthy? The flavor was hard to identify, but certainly not like any other gruyere I had ever had...it was foul.
So the question is, what makes good cheese go bad? What ails my usual favorite cheese?
