Q

Describe the climate/growing conditions of Lake County.

A

Though inland, it is cooler than other areas due to Clear Lake. Cited for young, volcanic soils.

High elevation vineyards with cited high air quality maximizes sun exposure, resulting in grapes with thicker skins, more anthocyanins, tannins, and polyphenols - and reduced pyrazines.

40
Q

Lake County is cited for its high elevations (1500-3000 ft), volcanic soils, and pure air quality.

What does this combination of factors bring to grape growing?

A

Increased solar potential / sun exposure, resulting in riper grapes with:

  • thicker skins
  • more polyphenols, tannins, anthocyanins
  • less pyrazine

And, less humidity with greater diurnal shifts, allowing grapes to retain their acidity.
