Winemaker Notes
Focusing first on the Cabernet fruit from our mineral-rich, volcanic soil sites nestled on the hillside slopes in the Alexander Valley. This vintage’s blend is uniquely crafted with a delicate inclusion of Malbec, and a hint of Merlot and Petit Verdot, showcasing intense black fruits enriched with lengthy velvety tannins.
Blend: 95% Cabernet Sauvignon, 3% Malbec, 1% Merlot, 1% Petit Verdot

I tasted the 2023 Cabernet Sauvignon in October, not long after it was bottled in August. Grapes were harvested October 5 through November 3. It was blended with 3% Malbec, 1% Merlot and 1% Petit Verdot and matured for 18 months in 55% new French oak barrels plus 10% concrete—a new aging vessel Aperture has started experimenting with. It has slowly unfurling scents of cassis, black cherry, dark chocolate, cast iron and floral hints. The full-bodied palate is impressively concentrated without over-ripeness, and its flavors are rich yet minerally. It has an haut couture frame of powdery tannins and refreshing acidity and a very long, elegant finish. It should be very long lived in the cellar.

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.
Nearly a northern extension of Napa Valley, Alexander Valley starts just north of the small, Knights Valley, and is just a few minutes drive from the Napa town of Calistoga. It is Sonoma County’s hottest AVA. But the Russian River, which runs through the valley, creates cooler pockets and its soft, alluvial soil is ideal for grape growing, especially Cabernet Sauvignon. In fact, some believe that Alexander Valley Cabernets truly rival the best from Napa Valley and many of the heavy-hitter producers have largely invested here.
In addition to Cabernet Sauvignon, which makes up over 50% of plantings, Merlot and old vine Zinfandel thrive here. Ample, fleshy Chardonnay and Sauvignon Blanc dominate white wine production. Some old-vine plantings of Grenache have also been discovered and more recent experiments with Sangiovese and Barbera show great promise.
