Kaiken is one of the more than 1,500 wineries in the province of Mendoza, which has three primary viticulture regions: Maipu, Lujan de Cuyo and the Uco Valley. The Andes Mountains make for a dramatic backdrop, and a range of accommodations, restaurants and tours provide amenities to complement the winery operations. More than 15,000 visitors arrive at Kaiken each year. It was the first of three wineries I visited in May. Here's what I learned from each of them.
