What is the difference in red and black rind hoop cheese?

You're likely thinking of red and black wax hoop cheese, not rind. There's no significant difference in the cheese itself, it's just a matter of presentation and branding!

Here's the breakdown:

* Red Wax: Often associated with "sharp cheddar" or "aged cheddar". This is a marketing tactic, as the wax doesn't actually affect the flavor or age of the cheese.

* Black Wax: Usually used for mild cheddar or cheddar blends to distinguish them from their sharper counterparts.

So, while there's no difference in the cheese itself, the color of the wax can give you a clue about its flavor profile. However, it's always best to check the label for specific details about the cheese's age and flavor!
