An icon of modern winemaking in the Napa Valley, Shafer Vineyards was founded in 1972 by John Shafer, who left a career in publishing to pursue his passion for oenology in California. John and family moved into an estate in Stag's Leap District and began work re-establishing vineyards on the surrounding land. Around five years later, the first Cabernet Sauvignon was produced and it was clear that John had a natural talent for winemaking. Since then, the portfolio has expanded to include Merlot, Syrah and Chardonnay-based wines to name but a few - quality is high across the board and the team pay close attention to preserving varietal character across all bottlings.

John sadly passed away in 2019 and the winery is now managed by his son Doug - a graduate of UC Davis. Doug continues his father's work in partnership with Elias Fernandez, assistant winemaker at Shafer Vineyards. Their flagship wine is Hillside Select, produced using 100% Cabernet Sauvignon and aged for 32 months in new French oak.

California is the heart of American wine production, accounting for around 80% of all U.S. wine. Its vast and varied landscape offers an extraordinary range of climates and terroirs, allowing a broad diversity of grape varieties and wine styles. Stretching over 1,100 kilometres from north to south, the state includes world-famous wine regions such as Napa Valley, Sonoma County, Paso Robles, Santa Barbara, and Mendocino.

Key wine towns include Napa, St. Helena, Healdsburg, and Santa Rosa. Napa Valley is renowned globally for its premium Cabernet Sauvignon, while Sonoma produces acclaimed Pinot Noir, Chardonnay, and Zinfandel. Further south, Santa Barbara is noted for its cool-climate Syrah and Pinot Noir, while Paso Robles excels with robust Rhône and Bordeaux varietals.

The most widely planted grape varieties in California include Cabernet Sauvignon, Chardonnay, Pinot Noir, Merlot, Zinfandel, and Sauvignon Blanc. The diversity of microclimates allows both cool- and warm-climate grapes to flourish.

California’s primary growing challenges include drought, water scarcity, and the increasing threat of wildfires, which can damage vineyards and affect grape quality through smoke taint. However, its abundant sunshine, varied topography, and innovative viticultural practices provide significant benefits, helping to maintain its reputation as a leader in premium New World wine.

Cabernet Sauvignon is one of the world’s most widely planted and celebrated red grape varieties, known for its deep colour, firm tannins, and remarkable ageing potential. Originating in Bordeaux, France, as a natural cross between Cabernet Franc and Sauvignon Blanc, it has become a global benchmark for structured, full-bodied red wines.

Viticulturally, Cabernet Sauvignon is a hardy, late-ripening grape that thrives in warm, sunny climates. It produces small, thick-skinned berries, contributing to its bold tannic structure and deep colour. The vine is relatively resistant to disease and adapts well to diverse soils, making it suitable for a wide range of terroirs.

Today, Cabernet Sauvignon is planted extensively across the world—from its French homeland in Bordeaux’s Left Bank, to California’s Napa Valley, Chile’s Maipo Valley, Australia’s Coonawarra, and South Africa’s Stellenbosch. It often forms the backbone of blends, particularly in Bordeaux-style wines, but also shines as a varietal expression.

Flavour profiles typically include blackcurrant (cassis), blackberry, mint, cedar, and tobacco, often developing notes of leather, earth, and spice with age. Styles range from fruit-forward and plush in warmer climates to structured and herbal in cooler ones. Cabernet Sauvignon’s power, elegance, and longevity make it a cornerstone of fine red winemaking worldwide.

Malbec is a dark-skinned grape variety originally from southwestern France, particularly Cahors, where it was historically known as “Côt.” Once widely grown throughout Bordeaux as a blending grape, its plantings in France declined due to susceptibility to frost, coulure, and disease. However, Malbec found a new home in Argentina, where it has become the country’s flagship variety.

Viticulturally, Malbec thrives in warm, sunny climates with significant diurnal temperature variation, which helps develop rich fruit flavours while preserving acidity. The grape is vigorous, with large berries and thin skins, making it prone to rot in humid conditions but capable of producing deeply coloured wines in dry environments.

Globally, Malbec is most famously planted in Argentina’s Mendoza region, where high-altitude vineyards produce intensely flavoured wines with smooth tannins. It is also cultivated in Cahors, Chile, the United States (notably California and Washington), Australia, and South Africa.

In style, Malbec ranges from the rustic, tannic, and earthy examples of Cahors to the plush, fruit-forward wines of Mendoza. Typical flavours include ripe black plum, blackberry, and blueberry, often accented by cocoa, violet, and spice notes. Well-made Malbecs are full-bodied, with deep colour, supple texture, and a crowd-pleasing balance of fruit richness and structure.

Merlot is one of the world’s most widely planted and popular red grape varieties, prized for its soft texture, approachability, and rich fruit character. Originating in Bordeaux, France—particularly prominent in the Right Bank regions of Saint-Émilion and Pomerol—Merlot is often blended with Cabernet Sauvignon and other Bordeaux varieties to add suppleness and ripe fruit.

Viticulturally, Merlot is an early-ripening grape, making it well-suited to cooler climates. It thrives in clay-rich soils, which enhance its plush texture and depth. However, it can be sensitive to frost and overly vigorous if not carefully managed, sometimes leading to high yields and diluted flavours.

Today, Merlot is grown extensively around the world, including in France, Italy, the United States (especially California and Washington State), Chile, Australia, and New Zealand. In each region, it adapts to different styles—from soft and fruity to structured and age-worthy.

Merlot wines are typically medium to full-bodied, with smooth tannins and flavours of plum, black cherry, blackberry, chocolate, and sometimes herbal or earthy notes. In warmer climates, the wines tend to be richer and fruitier, while cooler regions produce more restrained, elegant expressions. Merlot’s versatility and charm make it a staple of both varietal wines and blends worldwide.

Petit Verdot is a red grape variety originally from Bordeaux, traditionally used in small quantities in blends to add colour, tannin, and aromatic complexity. It plays a supporting role in many classic Left Bank wines, particularly in the Médoc, although its late ripening nature means it is only used in warmer vintages. As climate conditions have changed, Petit Verdot has gained renewed interest both within Bordeaux and in warmer wine regions around the world.

Outside of France, Petit Verdot is successfully grown in countries such as Australia, the United States (particularly California and Washington), Spain, Chile, and increasingly in Argentina and South Africa. In these warmer climates, the grape reaches full maturity more consistently, allowing for varietal expressions as well as blends.

Petit Verdot typically produces deeply coloured, full-bodied wines with firm tannins and good acidity. Aromas often include black cherry, plum, violet, graphite, and spice, with some examples showing notes of dried herbs, leather, and dark chocolate as they age.

Viticulturally, Petit Verdot is known for its late ripening, making it risky in cooler climates or short growing seasons. It can also be prone to uneven fruit set. However, when conditions are right, it adds depth, structure, and ageing potential to red wines.
