Winemaker Notes
The 2017 Mending Wall Tournahu Cabernet Sauvignon takes everything we loved about the 2016 and amplifies it. The mid palate has wonderful depth and power, while the ripe, fine tannin's provide structure and length without being obvious or drying. The 2017 is cut from the same cloth as the 2016 and offers a full-bodied, rich, smoky, meaty edge as well as lots of herbal, tobacco, and walnut nuances. Accessible now with a few hours in the in decanter, this wine has composition to age gracefully for at least a decade or more.

There’s a ripe herb/herbal edge in the 2017 Cabernet Sauvignon Tournahu Vineyard, which comes from a vineyard on the valley floor located on an old riverbed. Lots of black fruits, salted meats, and cured black olives define the bouquet, and it’s full-bodied, concentrated, and structured on the palate. It’s a serious wine that will benefit from 2-4 years of bottle age and keep for 15-20.
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.
St. Helena is in the heart of the Napa Valley, nestled between Calistoga to the north and Rutherford on its southern border. On its western side, the Mayacamas Mountains guard it from the cooling effects of the Pacific Ocean; to its east stand the Vaca Mountains. In conjunction, these mountain ranges serve to lock in summer daytime heat. But in the evening, cool air from the San Pablo Bay funnels up through the valley, creating very chilly nights. It isn’t uncommon for temperatures to drop 50 degrees, a shift that promotes a balance of sugar ripeness and acidity in wine grapes.
St. Helena contains a plethora of different soil types in a small area, which have been enhanced over centuries by rain runoff from both mountain ranges. Its vineyards cover a variety of terrain, spreading across the bucolic valley floor and its benchlands.
These ideal topographic and climatic growing conditions easily caught the attention of early winemaking pioneers. In fact, St. Helena is the birthplace of Napa Valley’s commercial wine industry. Dr. Crane founded his cellar in 1859, David Fulton in 1860 and Charles Krug in 1861.
Today there are no less than 400 separate vineyards planted within the 12,000 acres that make up the St. Helena appellation.
Revered most for its red wines based on Bordeaux varieties, namely Cabernet Sauvignon, the St. Helena appellation is also a source of superior Syrah, Zinfandel and Sauvignon blanc.
