Hello Cholula-- I am very familiar with Terrazas, they are a very good producer. Terrazas belongs to the French Multinational LVMH, and are very much a global player in the industry. They make a lot of wine, some very good, and also some others that are just "also-rans". Nothing Terrazas will produce will ever be bad, but perhaps some of their more standard stuff will have no flaws, but perhaps lack a "soul"... if you know what I mean.

Terrazas has many lines of wines... Im assuming you found the Terrazas Alto which is their basic every day wine (the one with the colorful label showing the Andes Mountains). If priced correctly, its a good option for everyday drinking. I think that Cabernet is their best varietal, although the Malbec is their best seller.
