Lokoya Diamond Mountain Cabernet Sauvignon 2018
Critical AcclaimAll Vintages
Established in 1995, Lokoya is a collection of four distinct Cabernet Sauvignons from four of Napa Valley’s most celebrated mountain appellations: Mount Veeder, Howell Mountain, Spring Mountain and Diamond Mountain. These limited-production wines are 100% Cabernet Sauvignon, fermented with native yeast, and bottled unfined and unfiltered, resulting in the purest expression of place.
Cabernet Sauvignon as lens, site as conveyor—the grape variety and winemaking for the four wines remain consistent, allowing the vineyard sites to shine with the climate, soils and sunlight all fully expressed in the glass.
Given the high elevation of the sites, the vineyards demand constant attention. The deep understanding of the vineyard trajectory in each vintage comes from Winemaker Christopher Carpenter’s years of expertise. Intervention is kept to a minimum both in the vineyard and in the cellar, leaving the fruit to express itself as naturally and eloquently as possible.
Diamond Mountain is the northernmost mountain appellation in the Mayacamas Range, on the northwest side of the valley floor, above the town of Calistoga. Defined mainly by elevation, vineyards are planted at 400 to 2,200 feet.
Diamond Mountain vineyards receive plenty of sunshine at these elevations and are typically above the coastal fog line. But given its western proximity, the area still easily cools down from early morning and late afternoon Pacific Ocean breezes. The AVA (American Viticultural Area) covers 5,000 acres but just over 500 acres are under vine.
Diamond Mountain soils, mainly weathered, red sedimentary rock and decomposed, volcanic ash, are infertile, quick-draining and produce small, thick-skinned grapes, bursting with chewy tannins.
Cabernet Sauvignon, Merlot, Cabernet Franc, Malbec, Petit Verdot and Zinfandel have great success here.
Like other sub-appellations in Napa Valley, the Diamond Mountain area had no shortage of pioneer winemakers. Rudy von Strasser led the effort for Diamond Mountain to acquire AVA status in 1999.
A noble variety bestowed with both power and concentration, Cabernet Sauvignon enjoys success all over the globe, its best examples showing potential to age beautifully for decades. Cabernet Sauvignon flourishes in Bordeaux's Medoc where it is often blended with Merlot and smaller amounts of some combination of Cabernet Franc, Malbecand Petit Verdot. In the Napa Valley, ‘Cab’ is responsible for some of the world’s most prestigious, age-worthy and sought-after “cult” wines. Somm Secret—DNA profiling in 1997 revealed that Cabernet Sauvignon was born from a spontaneous crossing of Cabernet Franc and Sauvignon Blanc in 17th century southwest France.
