This is excellent sharp cheddar cheese. It's flavorful and it slices nicely without falling apart. These are my two prime criteria. It's got to be easy to get onto crackers, and taste good once there. I'm not that hard to please.
My only disappointment was, I guess, one of failed expectations. That is, the name of the product led me to believe that it would somehow be profoundly different from other sharp cheddar cheese, of which I've eaten approximately 90 billion tons in the past. I couldn't find that it was. I'm not sure that a side-by-side taste test of this versus, say, Cracker Barrel or Cache Valley brands of sharp cheddar would show much of a difference. On the other hand, I haven't actually conducted such a test, and my sensory memory is sufficiently undeveloped that I could be totally wrong in that guess.
As long as you approach it with expectations of a very nice sharp cheddar, but not anything genuinely unique, I think you'll be happy with it.
Will I buy it again?
Meh. This is not at all "extra extra-sharp." Cracker Barrel's extra sharp is much sharper, and—if memory serves—more flavorful too.
