What are "galets" in the context of the Chateauneuf-de-Pape terroir?

  1. Clay particles beneficial for drainage

  2. Large stones that store heat

  3. Rocks that erode to fertilize the soil

  4. Minerals that enhance flavor

The correct answer is: Large stones that store heat

In the context of the Châteauneuf-du-Pape terroir, "galets" refer to large stones, often rounded and smooth, that play a significant role in the vineyard's microclimate and ecology. These stones are primarily composed of rolled gravel and serve multiple purposes in the cultivation of grapes. One of their key benefits is their ability to absorb heat during the day and then radiate it back at night. This heat retention can help in moderating the temperature, providing a warmer environment for the vines, especially during cooler evenings, which is vital for grape maturation. Additionally, the presence of galets can aid in soil drainage, preventing water accumulation that could adversely affect root development and vine health. This unique combination of heat retention and drainage contributes to the overall terroir, impacting the flavors and characteristics of the wines produced in the region. The galets are a distinctive feature of Châteauneuf-du-Pape, crucial in producing the rich, complex wines the area is known for.
