Nothing makes cheese taste better than seeing the place where it’s made. Alas, most American creameries don’t welcome visitors. Sanitation is the main issue, and few small producers have the staff for tours. But in California’s scenic Anderson Valley, Pennyroyal Farmstead Cheese is charting a different course. In March, the three-year-old Boonville creamery opened a tasting room and began offering tours. From anywhere, it’s worth the journey.
