Hi Teresa,
I'm a novice at cheesemaking, myself, so I don't have much expertise. We didn't have a fontina recipe, so we used an emental recipe from the Home Cheesmaking book. We used thermophilic starter, and my mom cultured the fontina by chopping up about half an ounce of fontina cheese and blending it with milk, and letting it sit in a warm place for a few days.
Mom babied that cheese, it was the first one she ever made, and she opened it at Christmas, which was about 2 months. I'm pretty sure it was supposed to age at least three months, but anyway...
The cheese tasted like fontina! It was very hard, though, even grating hard, like a fontina flavored parmesan. in only 2 months!
She didn't have a cave for it. she kept it in her pantry the whole two months.
