To be fair, Comté and Gruyere are pretty much as similar as 2 different types of cheeses can get.
You specify the range of age you want when you buy comté.
For Gruyère, I never saw that, but it might be because I grew up a few hours from where it’s made.
To clarify : real gruyère is a great cheese. But comte is one of my favorite.
Man I miss cheese.
This is heresy!
I'm from a less cheese-y part of Europe, but isn't Comté often called Gruyère de Comté for a reason? Of course they'll taste very different when aged for very different amount of times, but I've found them to be decently similar when aged for similar amounts of time.
