The winemakers at Beringer Vineyards draw on Rhine Valley fermentation techniques to concoct their piquant libations in facilities dating back to 1877 and protected by the National Register of Historic Places. At the start of each tour, guides lead participants through the demonstration vineyard at St. Helena, where grapes wander forth from the elevated slopes of an alluvial plain unaided by shepherds or GPS. Groups then enter the stone winery, where staff members blend wines using gravity flow and methods that have changed very little since the winery’s founding. Guests see how wine flows to a lower level for fermentation before cascading farther down into hand-hewn cavern tunnels to age and languish, like a freeloading brother, for months without paying rent. As participants wander the 1,200-foot passageway, they learn facts such as how the rock walls serve as natural insulation, and sip four of the estate’s wines while guides discuss professional tasting techniques.
