Many of California’s best Merlots come from the sleepy town of Calistoga, on the Northern-most end of Napa Valley.  The area is distinguished by volcanic soils and the largest diurnal temperature variation in Napa Valley.  Daytime highs and night time lows span up to 50 degrees Fahrenheit, and while the hot daytime temperatures allow the grapes to develop deep and compelling flavors, the cool nights help to maintain acidity and structure.  With all of the contributing factors working in unison, this area has proven that it can produce some of the best Merlot in California… Just look at last year’s #1 wine in the Wine Spectator.  Interestingly, Duckhorn’s iconic 3 Palms Vineyard is just a short distance from Barlow’s Estate Vineyard and I believe the micro-climate on the South-Eastern edge of Calistoga where both of these Merlots originate is perfectly suited to produce some of Napa’s best Merlot.
