Winemaker Notes
Critical Acclaim
All VintagesPurity and brilliance on the nose with so much currant and flower character. Roses, currant bush and fresh leaves, too. Brightness is the word that comes to mind. Full-bodied and broad-shouldered. Juicy and so gorgeous now. Balance is so wonderful here. All about harmonious fruit and tannin balance. I like it slightly better than the excellent 2014. 81% cabernet sauvignon, 4% petit verdot, 7% cabernet franc, 6% merlot and 2% malbec.
This wine was too much—too much like a caricature for me,” winemaker Michael Silacci confessed to me while tasting the 2015 Opus One together again recently. “So, when we took it out of barrel to prepare for bottling we added a few more components.” Medium to deep garnet-purple color, it bursts from the glass with beautiful violets, lavender, rose hip tea and chocolate-covered cherries scents over a core of crushed blackberries, black cherries, cassis and iron ore. Medium to full-bodied, the palate is wonderfully bright and crunchy, with bags of fresh black and red berries and a wonderfully plush, finely grained texture, finishing long and fragrant.
Pure, rich dark berry, plum and gravelly earth flavors are framed by spicy, cedary oak notes, ending long, clean and elegant, with just the right touch of tannins. Cabernet Sauvignon, Petit Verdot, Cabernet Franc, Merlot and Malbec.







Learn about Opus One, it’s history, the winery and the wine.
History of Opus One
Opus One is a partnership founded by Baron Philippe de Rothschild of Chateau Mouton Rothschild in Pauillac, France, and renowned Napa Valley vintner, Robert Mondavi. Producing luxury wines from its Napa Valley vineyards, the partnership made its first vintage in 1979 and has made wine at Opus One since 1991. The facial profile of the two founders is visible on their iconic label.
Opus One Wine
The essence of time is expressed in Opus One wine by the character of each vintage. Place, often defined as terroir, represents the geography, the climate and the essential human element which is captured in the wine’s balance between power and finesse, structure and texture.
Guided by the vision of our founders, winemaker Michael Silacci combines intuition and technical acumen with the dual perspective of viticulturist and winemaker. From tasting berries to careful sorting and extended aging in new French oak barrels, each stage of the winemaking process is afforded the same meticulous consideration and attention. After 18 months, the Opus One wine is bottled and held an additional 15 months until release on October 1st each year.
The Opus One Winery
Rising gracefully from the vineyards, Opus One winery stands in subtle celebration of the land and the open space that surrounds the estate. It remains an ongoing testament to the founders’ vision of a singular wine that transcends generations.
The estate vineyards of Opus One, comprised of four parcels, sit in the western portion of the famed Oakville AVA in Napa Valley. Two parcels, totaling 100 acres, are within the renowned To Kalon Vineyard. These are complemented by the combined 70 acres of the Ballestra and River parcels, which envelop the winery. In the vineyards, hand-harvesting and other traditional approaches are taken wherever they work best. When modern techniques benefit the winegrowing process, they are researched, evaluated and integrated into practice

Home to some of the most sought-after Cabernet Sauvignon in America, Napa Valley’s Oakville district stretches across the center of Napa's valley floor and foothills between the Vaca and Mayacamas Mountains. This AVA is home to the legendary To Kalon Vineyard and Martha's Vineyard, as well as many powerhouse wineries including Screaming Eagle, Silver Oak, Robert Mondavi, Opus One, Far Niente and Groth.
The climate is generally warm and agreeable, resulting in year after year of favorable vintages. Summer days see a gentle tug of war between warmer inland air and the cool air coming in from the San Pablo Bay, creating an ideal environment to grow red varieties. Oakville's diverse soils, namely ancient sea bedrock, clay and gravel, are well-drained, and perfect for high-caliber viticulture.
Cabernet here is often bottled varietally but is also popular in Bordeaux Blends. Oakville wines are known for their silky, sensual textures, structured tannins, dark and brooding fruit and lovely aromatics. These age-worthy and prestigious wines are favored by collectors throughout the world.

One of the world’s most classic and popular styles of red wine, Bordeaux-inspired blends have spread from their homeland in France to nearly every corner of the New World. Typically based on either Cabernet Sauvignon or Merlot and supported by Cabernet Franc, Malbec and Petit Verdot, the best of these are densely hued, fragrant, full of fruit and boast a structure that begs for cellar time. Somm Secret—Blends from Bordeaux are generally earthier compared to those from the New World, which tend to be fruit-dominant.
