Guenoc Valley AVA

<p>Guenoc Valley is an <a href="/facts/American_Viticultural_Area/BpCGWUsQ">American Viticultural Area</a> in <a href="/facts/Lake_County,_California/fvxBsSez">Lake County</a>, <a href="/facts/California_(wine)/a5947h0M">California</a>, United States, about 15 mi (24 km) north of the town of <a href="/facts/Calistoga,_California/vG4n3tfv">Calistoga</a>.  Guenoc Valley AVA was the first American Viticultural Area designation granted to an area with just a single winery.
</p><p>Guenoc Valley is a small inland <a href="/facts/Valley/gKmvE6L1">valley</a> comprising an <a href="/facts/Alluvial/Bo78QRlp">alluvial</a> fan of <a href="/facts/Arroyo_Seco_AVA/l2e5c68w">Arroyo Seco</a> and Conejo Loam series <a href="/facts/Soil/5Ddpr3QM">soils</a> isolated from surrounding areas by rocky ridges. Its geographical location also affects the climate.  Guenoc Valley has slightly less <a href="/facts/Rainfall/MLqcQEyx">rainfall</a> than the nearby <a href="/facts/Middletown,_California/reNtY8t8">Middletown</a> area. Guenoc Valley receives approximately 45 inches (114 cm) to 50 inches (127 cm) of rain per year, while Middletown receives approximately 60 in (152 cm) per year. Guenoc Valley also experiences slightly greater seasonal temperature extremes, being warmer in the summer and colder in the winter. Also, due to the surrounding ridges, fog is generally less severe than in Middletown.  For these reasons, the <a href="/facts/United_States_Department_of_the_Treasury/lDmua740">United States Department of the Treasury</a> <a href="/facts/Alcohol_and_Tobacco_Tax_and_Trade_Bureau/qIfKGzIT">Alcohol and Tobacco Tax and Trade Bureau</a> determined that Guenoc Valley possesses geographical features which distinguish the area viticulturally.
