When a viticulturist is choosing what variety to plant, another important factor must be taken into consideration: the clone. The clone of a grape is basically its subdivision within the variety, or a further distinction beyond its varietal. Vines of a particular clone are all originally from a mother vine, resulting from spontaneous genetic mutations that occur in the vines over time. Different clones are chosen based on their individual characteristics; budbreak, berry color, disease resistance, cluster size, yield, flavors, and aromas are all characteristics that can be a result of the clonal selection. Winemakers will often utilize a variety of clones in order to create the complex, well-balanced wine they hope to achieve.


Here’s a look into what clones are used to make the unique wines of Hearthstone Vineyard:

Hearthstone’s Cabernet Sauvignon includes clones 337 and 4. Clone 337 is a French clone and is commonly the clone of choice for this varietal in California. This clone is chosen for its small berries and moderate yield in the vineyards. Wines produced from this clone are often complex with a concentrated flavor profile. Clone 4 originated in Mendoza, Argentina and results in moderate yields and strong flavor intensity with great color, aromas, and balance in the wines.

There are at least fourteen clones of Sangiovese that are recognized in the world of viticulture. With this varietal, we use the Brunello clone, which is perhaps the most popular clone of Sangiovese.

Now, let’s talk about Pinot Noir. In our own vineyard alone, there are 8 clones of Pinot Noir. Why so many? This allows for Paul to be more specific in choosing what flavor profiles he hopes to exhibit in the wine. When it comes to fermenting the juice, Paul aims toferment the juice by clone or a combination of two clones in order to gain an accurate depiction of the flavor profile imparted by the clone. Our clones of Pinot Noir include #16, #32, #115, Pomar 4, #667, #777, DRC, and HMR; the majority of the Pinot Noir is made up of the DRC and HMR clones. Here’s a closer look into a few of those clones:

#115 – This clone has played a pivotal role in the development of Pinot Noir in California’s vineyards and often serves as the backbone to the structure of a Pinot Noir.

#667 – This clone orginated in Dijon, France, and is often chosen for its high tone aromas and great finish on the palate. As a result of the tannins it produces, this clone is also chosen for aging potential.

#777 – Also of Dijon origin, clone #777 is rather rich and dark, producing a velvety mouthfeel in the wine. Clone #777 is known for producing intriguing and complex wines.


I hope this has helped you learn more about clones in the world of winemaking!
