My boyfriend and I did a private all-day wine tour today in Mendoza with Gustavo Pedro Delucchi, and I cannot recommend him strongly enough. He was a remarkable guide. He speaks excellent English, is very knowledgeable about wine, history, and politics, and he knows everyone at the vineyards and got us VIP treatment (or at least it seemed like it to us). If you're going to Mendoza, i would strongly recommend booking a tour with him. It was 600 Argentinean pesos per person, plus tasting fees, and it was worth every penny. His email address is firstname.lastname@example.org, and his website is http://www.gustavodelucchi.com/. He also said that he organizes private trips to the Andes. We don't have time for one of these trips, but if we come back we will definitely do one.
We had lunch at the Casa del Visitante at the Zuccardi vineyard. It was delicious. We did the traditional menu, as opposed to the tasting menu. We started with three different types of empanadas -- cheese, onion, and beef. The onion ones were particularly good. We then had salad with roasted vegetables, followed by beef ribs, beef filets, and pork. All the meat was cooked right outside on the grill. The food was all delicious, perfectly cooked, and accompanied by Zuccardi wines. It was a fantastic experience.
