Meet your guide at your Santiago hotel and climb aboard a comfortable tour vehicle. Embark on the 2.5-hour drive south of Santiago's city limits to La Postolle winery (or similar), a family-operated viña (vineyard) and one of the country's producers of award-winning wines.
Sit down for a tasting of varietals like carmenere, viognier and syrah while admiring the near rows of grapevines and rolling hills beyond. Get to know the winemakers and ask any questions about the wine production process.
Continue to the town of Santa Cruz, ground zero for the Colchagua Valley's wine-related activities. At Ruta del Vino, a gourmet boutique, pick up your souvenir bottle of reserve wine (included) to take home.
Take a break for lunch; if you've chosen the 'Tour Plus Lunch' option, head to an intimate local restaurant. If not, take recommendations from your guide or scout a place on your own.
With your hunger sated, continue to the day's second winery, Montes or Viu Manent. Both wineries produce several award-winning varietals, including malbecs and syrahs.
End your day at the Colchagua Museum (Museo de Colchagua), back in Santa Cruz. Geat a look at Chile's history through displays on the country's pre-Columbian cultures and some 300-million-year-old fossils.
Return to your Santiago hotel for drop-off at the conclusion of your 9-hour tour.
