Hertelendy Signature Mountain Blend 2021

Napa Valley, California | Merlot-led Bordeaux-style red blend

Opulent, refined and beautifully layered, Hertelendy Signature Mountain Blend 2021 is a small-production Napa Valley red that marries the plush richness of Merlot with the structure and complexity of classic Bordeaux varieties. Sourced predominantly from the estate's Rockwell Ridge Vineyard, this distinctive blend showcases mountain-grown fruit, impressive concentration and remarkable balance.

The nose opens with ripe blackcurrant, black cherry, blackberry and dark plum, layered with violets, dark chocolate, tobacco, graphite and earthy, loamy notes. On the palate, concentrated dark fruit combines with sweet spices and mocha, supported by firm yet refined tannins and refreshing acidity. Rich and full-bodied, the wine maintains an appealing sense of freshness and tension, culminating in a long, polished finish.

What Makes It Special?

Hertelendy's Signature Mountain Blend is inspired by the Right Bank wines of Bordeaux, where Merlot often takes center stage. Here, Merlot provides the wine's generous texture and dark-fruit richness, while Cabernet Sauvignon, Cabernet Franc, Malbec and Petit Verdot contribute structure, aromatic complexity and depth.

The wine is sourced primarily from Rockwell Ridge Vineyard in Napa Valley's Crystal Springs AVA, with additional fruit from Atlas Peak, Coombsville and Silverado Bench. These carefully selected vineyard sources contribute the wine's distinctive combination of ripe fruit, mineral character and structured tannins.

Production is limited to approximately 150 cases, making this a particularly appealing choice for collectors and customers seeking something beyond the familiar Napa Cabernet Sauvignon.

The 2021 Vintage

The 2021 vintage delivers an especially compelling combination of concentration and freshness. Critics highlight dark berries, black cherry, floral notes, graphite, tobacco and spice, with a full-bodied palate that remains refined rather than simply powerful.

Owen Bargreen praised the wine's combination of red florals, wet stone, blackberry compote and crème de cassis, noting its soft texture and underlying energy. He suggested a drinking window extending from 2024 to 2044.
