Yes, Gouda is a good long-term agining cheese. HOWEVER, there are 5 year old Goudas on the market that I don't like either. The flavor is amazing, but they are just too dry for my taste.
There is one adjective that sells more cheese than any other - creamy.
I love the flavor of Italian Grana cheeses but I find that many of my wholesale buyers and chefs aren't very interested. Especially when aging for a year, I just can't compete with the flood of cheap products on the market. So, I have just started making a Creamy Romano. Full fat (4%) milk, double dose of Lipase, larger curd cut, and cooked at 112F instead of 117F. For the purist, this obviously won't be a true Romano, but I am hoping that this will be a good Italian flavored table cheese at 75-90 days.
