2018 Louis M. Martini, Monte Rosso Vineyard Cabernet Sauvignon, Sonoma Valley California, USA

Louis M. Martini Winery

Sonoma County

North Coast's Sonoma County is California's largest AVA with 19,800 ha (2005) of vines. It has forever been the home of the meek and mild small grower as compared to the grandeur and might of neighbour Napa; more picturesque too, as much of the sandy, gravely loam land belonged to true orchards and fruit farms until the 1970s.

Sonoma Valley covers a small part of Sonoma County but its wines often outshine its illustrious neighbours in Napa County. Zinfandel, Pinot Noir, Chardonnay, and Cabernet Sauvignon are cultivated here with much success. Sonoma Valley has long enjoyed a special place in the history of California wine. The first vineyards in the valley were planted by Franciscan monks in 1823. In 1857 Agoston Haraszthy, one of the founding fathers of California's commercial winemaking, opened here the highly successful Buena Vista Winery.

Closer to the coast are the region's top producing AVAs for Pinot Noir and Chardonnay: Russian River, Sonoma Coast and Green Valley, while the slightly warmer Dry Creek and Alexander Valleys have earned a reputation as a hotspot for Cabernet, and increasingly, Zinfandel and Merlot.

Recommended producers
Ridge, Teira, Williams & Selyem, Rochioli are definitely worth investigating.

Cabernet Sauvignon

The most famous red wine grape in the world and one of the most widely planted.

It is adaptable to a wide range of soils, although it performs particularly well on well-drained, low-fertile soils. It has small, dusty, black-blue berries with thick skins that produce deeply coloured, full-bodied wines with notable tannins. Its spiritual home is the Médoc and Graves regions of Bordeaux where it thrives on the well-drained gravel-rich soils producing tannic wines with piercing blackcurrant fruits that develop complex cedarwood and cigar box nuances when fully mature.

The grape is widely planted in California where Cabernet Sauvignon based wines are distinguished by their rich mixture of cassis, mint, eucalyptus and vanilla oak. It is planted across Australia and with particular success in Coonawarra where it is suited to the famed Terra Rossa soil. In Italy barrique aged Cabernet Sauvignon is a key component in Super Tuscans such as Tignanello and Sassicaia, either on its own or as part of a blend with Sangiovese.
