One of the valley's upstarts, this boutique winery was founded by Swiss attorney Mauro Von Siebenthal in the late 1990s. Mention Von Siebenthal in local wine crowds and you will get a consistent thumbs-up on the overall quality of the vineyard's cabernet sauvignon, merlot, and carmenère to cabernet franc, petit verdot, and syrah. Varied soils allow the winery to grow all their grapes on site. Given the winery's limited production, its top wines include the super premium Montelig, premium Carabantes and Parcela 7, and carmenère reserva, which won the prestigious Concours Mondial de Bruxelles 2005 Tastings, with Von Siebenthal's sommelier provide the sort of personalized attention most visitors crave. Tours cost $10 (£6.70) per person.
