I'm partial to cave-aged Gruyere. Even the 3-6-month-old one is great. The over-1-year-old variant gets pricey at around $35 per lbs.
For that it would have to be a real miracle cheese. Most cheese is tolerable at best. Maybe it just has to cost 50 times as much to actually be good.https://www.wisconsincheesemart.com...ter-pound-23-years-old?variant=42807290888423
$228.0 per pound! yikes!!
That looks like a EPA Super Fund site.
