Argot Napa Cabernet Sauvignon Sugarloaf Vineyard is made from 100 percent Cabernet Sauvignon.
Sugarloaf’s terroir continues to impress with its expression of classically-styled Napa Valley Cabernet Sauvignons — impeccably pure black and red fruit character; broad, rich, perfectly ripe tannins; classic Napa Valley notes of cigar leaf, eucalyptus, and freshly-tilled earth; and definitive complexities of clove, all-spice and bay leaf. Having assessed past vintages with a few years of age, we have come to greatly value the significant reward Sugarloaf delivers after a few years in the cellar.
From Block 6, an acre of fiercely steep, ferociously rocky hillside, located in Napa’s far south-eastern foothills, deeply affected by the cooling influences of San Pablo Bay. One of the latest harvests in all of Napa Valley each vintage. Mother Nature was kind to this site in 2019, being our most bountiful year here ever. With perfect set, and vines displaying great health, this normally stingy hillside delivered superlative quality, without restraint of yield. After a slow start in the Spring, 2019’s particularly warm September and October played beautifully to the vineyard’s strengths, and delivered a classic Halloween-time harvest.
Review:
"It is not often that you see a 100% Cabernet Sauvignon coming from this rising star, cooler-climate vineyard in south Napa. This wine comes exclusively from the low-yielding, steep, rocky "Block 6." Deep purple-black in color, the 2019 Cabernet Sauvignon Sugarloaf Vineyard needs a little coaxing to reveal wonderfully pure scents of blackcurrant cordial, juicy blueberries and ripe blackberries, plus suggestions of iris bulb, dark chocolate, molten licorice and cedar chest. The big, rich, seductive, full-on full-bodied palate is laden with ripe, energetic black berry layers, framed by firm, ripe, grainy tannins and seamless freshness, finishing long and perfumed. A stunning, true-blue Napa blockbuster with its own very evocative signature, this comes highly recommended! 175 cases were made. - Lisa Perrotti-Brown"

The nose of our the Cabernet Sauvignon shows remarkable purity, opening with juicy fruit-punch and layered notes of blue and red fruit dried with sweet herbs. The palate builds with blackberry pie filling, baker’s chocolate, and freshly ground coffee, underscored by an earthiness of loam and underbrush. Acidity is finely tuned, carrying structure through the middle and sides of the wine. For those who can wait, cellar this bottle for several years. For those who cannot, double decant 4–5 hours before serving and let the wine come fully alive.

Review:
"How do you do Cabernet the Donelan way—and do it in Sonoma? The answer began with archetyping older styles of Cabernet. The vineyard lies near Skipstone, encompassing sites such as T-T Vineyard, Obsidian, and Constant on Diamond Mountain. For Joe Donelan, the goal was to craft a Cabernet reminiscent of what Mondavi was producing in the 1970s and early 1980s—wines defined by freshness, clarity, and balance rather than sheer weight. The result is vivid, bright, and pure-fruited, with an immediate freshness factor. Red berry fruit, cherry, and cassis lead the way, framed by a medium-bodied structure with velvety-textured tannins and a creamy mid-palate that makes the wine deeply engaging and remarkably easy to drink. Sagebrush and black olive notes lend savoury complexity, joined by subtle hints of tobacco, all carrying through to a long, mineral-driven, fruit-focused finish. - Jonathan CRISTALDI"
