Marcassin

Marcassin takes its name from the French word for a young wild boar. Helen Turley planted the estate's Sonoma Coast vineyard near Fort Ross in 1991, and the label's debut wine was the 1991 Upper Barn Chardonnay, sourced from the Gauer Vineyard in Alexander Valley; a Santa Clara University academic profile of Turley separately dates the label's formal founding to 1992. At the time, Turley and her husband, viticulturist John Wetlaufer, were already well known as consultants to a string of Napa and Sonoma wineries. Turley was educated at St. John's College in Annapolis, Maryland, and graduated from Cornell University. She began her career in 1977 in the lab at Robert Mondavi Winery, followed by a short period at Chappellet Winery, then took a winemaking position in Kentucky after having difficulty finding a California winery willing to hire her in the cellar. She returned to California in 1984 as winemaker for B.R. Cohn, then became the founding winemaker at Peter Michael Winery in the Knights Valley, where she helped define an emerging style of California Chardonnay and developed Les Pavots, Peter Michael's flagship red Bordeaux-variety blend. She also made wine, until 1995, for Turley Wine Cellars, the Zinfandel producer owned by her brother Larry Turley. Turley went on to consult for nearly 20 clients, among them Peter Michael, Pahlmeyer, Colgin, Bryant Family, and Martinelli (where she consulted from 1993 to 2010), before focusing her attention on Marcassin.

Robert Parker wrote of the Marcassin Chardonnay: "In the autumn years of my career I have come to think this (Marcassin) may be the greatest chardonnay in the world." The Wine Advocate named Marcassin a winner in its inaugural Extraordinary Winery Awards, and in the same 2017 program gave Helen Turley its first-ever Lifetime Winemaker Achievement Award for the Americas, its highest honor for a winemaker's contribution to a region. Announcing the award, then-editor-in-chief Lisa Perrotti-Brown said Turley had helped forge wineries including Colgin, Bryant Family, Peter Michael, Pahlmeyer, and Martinelli into what she called modern-day legends, and credited Turley with mentoring winemakers Mark Aubert, Heidi Barrett, and Philippe Melka. Turley received Wine Spectator's Distinguished Service Award in 2010, and was part of the class of inductees into the California Hall of Fame announced by Governor Gavin Newsom's office in November 2019.

The Marcassin Estate Vineyard covers 20 acres on the Sonoma Coast near Fort Ross. Speaking at Wine Spectator's 2014 New York Wine Experience, viticulturist John Wetlaufer described the vineyard as dry-farmed and marine-influenced, about three miles from the Pacific Ocean and sitting at 1,400 feet, with volcanic, highly fractured, well-drained soil across two distinct slopes; a separate winery profile puts the elevation at approximately 1,200 feet. The original 10 acres were planted in equal parts Chardonnay and Pinot Noir starting around 1991, with the Pinot Noir plantings specifically dated to 1992; a further 12 acres of Pinot Noir were added in 2002, bringing the estate to its current split of roughly two-thirds Pinot Noir and one-third Chardonnay. Chardonnay is planted to older Wente clonal material along with Dijon, Mt. Eden, and Hyde selections; Pinot Noir clones include Swan, Martin Ray, Calera, and Pommard. The vineyard reached full production in 2009, and after 2010 Turley has drawn her Pinot Noir and Chardonnay only from this estate fruit. For the Chardonnay, grapes are typically harvested early in the morning, often before sunrise, to preserve freshness.

Marcassin's winemaking is designed to leave vineyard character largely unmanipulated. Chardonnay clusters are pressed whole; Pinot Noir clusters are destemmed and cold-soaked, with one pump-over a day, before native-yeast fermentation. Wines are kept on the lees for 6 to 8 months and aged in 100% new Francois Freres French oak barrels for an average of about 12 months. No fining, filtering, or cold stabilization is used, so bottles, particularly the Chardonnay, can show natural sediment or a cloudy appearance. Wines are typically released about five years after the vintage. The label's imagery depicts the sorceress Circe transforming Odysseus's men into pigs, a reference Turley has tied to the winery's no-manipulation philosophy: "No hocus pocus, no fining, no filtering, no hanky panky, maybe just a little wand waving." In 2013, Marcassin hired its first assistant winemaker, Ryan O'Donnell; the following year the winery introduced a new Pinot Noir, Bessie's Block, in small volumes averaging about 225 cases a vintage.

Marcassin produces roughly 2,500 to 3,000 cases of Chardonnay and Pinot Noir a year, about 100 barrels, with Pinot Noir accounting for about two-thirds of the volume. Roughly 80% of the wine is sold directly to mailing-list members at $125 a bottle; the waiting list to join is reported to hold about 5,000 names, with some prospective buyers waiting years for an allocation. What does not go to the mailing list has commanded some of the highest secondary-market prices of any domestic Pinot Noir, reported in the range of $300 to $350 or more per bottle. A dedicated Prince of Pinot profile describes the winery as very private, with not much information forthcoming, and Marcassin's own website is limited to a mailing-list waiting-list sign-up form.
