Russian River AVA Climate
The Climate of the Russian River AVA
Nonetheless, there are some general facts that can be claimed about the majority of the viticultural area. The most defining feature of the valley’s climate is fog.
The Russian River winds through the rolling hills of the AVA and acts as a gateway for coastal fog. Nights and mornings are cool as the fog creeps up the river and its tributaries.
Because of the prevailing cool temperatures, grapes are usually harvested about two weeks later than in nearby regions. The combination of high acidity from the cool weather and thorough varietal development from two extra weeks on the vine produces complex, balanced wines. Hartford Court Winery makes several great wines that do the AVA justice.
