VALTICE, Czech Republic — A dozen years ago, Mike Mazey was making wines in his native Australia when he received an unexpected job offer from Europe: Come to the Czech Republic and teach us your craft.

Intrigued, Mr. Mazey, whose contract as a winemaker for Ausvin, an Australian producer, was about to expire, left for South Moravia, the main wine-producing region of the Czech Republic. He had never heard of Moravia, nor of some of the grape varieties he would be working with, but he was immediately taken with his new home.

“Moravia has some of the most spectacular vineyards I have ever seen,” he said. Adding to the attraction for him were the centuries-old wine cellars underneath towns like Valtice and its neighbor, Lednice, and grape varieties like palava and irsay oliver that are predominantly found in South Moravia. “An unforgettable experience,” he said.
