ANNE SAXELBY had what she calls an “aha moment” a couple of years ago when she drove upstate to try the cultured butter made by Evans Farmhouse Creamery in Chenango County. Ms. Saxelby, who owns Saxelby Cheesemongers in Manhattan, said that for all the butter she had eaten in her life, “I had really never had butter before  this is butter.”

More and more people across the country are being treated to the same aha experience as they find a burgeoning variety of fresh dairy products made in small batches on little farms and in small creameries. And it’s worth the extra money.

These artisanal operations are turning cow, goat or sheep milk into simple, straightforward foods like crème fraîche, butter, buttermilk, ice cream, puddings, custards, yogurt, yogurt-based sauces and yogurt drinks. Many of these dairies also sell unhomogenized, and in a few cases even unpasteurized, milk with an old-fashioned farmhouse flavor.

The movement is, in some ways, an offshoot of the American cheesemaking revival that began 15 to 20 years ago, and some of the creameries make fresh cheeses like mascarpone, mozzarella and ricotta that let the quality of the milk speak for itself.
