Barlow Calistoga Unfiltered Merlot 2013

One of Napa Valley’s oldest wine growing subregions but last to gain appellation status, Calistoga occupies the northernmost section of the valley. Beginning at the foot of Mount St. Helena, its vineyards stretch over steep canyons and roll out onto the valley floor. The soils in Calistoga are volcanic, which means they are heavy in minerals, low in organic matter and allow good drainage for vine roots, creating less green growth and more concentration of flavor within the grape berries.
