Which of the following is a characteristic of Chilean wine regions according to the material?

• A. Similar to the California coast
• B. Phylloxera free
• C. Caramenere
• D. High rainfall

Answer: (B)

Chilean wine regions are described as phylloxera-free, a status rooted in their geographic isolation and strict quarantine controls. Because phylloxera hasn’t taken hold there, vineyards can be planted on their own roots without grafting onto American rootstocks. This distinction matters beyond a factoid: it shapes vineyard management and potential wine styles, since root systems and their interactions with soil and water can influence vine vigor and fruit characteristics. The other options don’t fit this material: the climate isn’t highlighted as being like the California coast, Carménère is a grape variety rather than a regional trait, and the regions are not characterized by high rainfall.
