Spencer Roloson Winery

Spencer Roloson Winery was a California wine producer founded in 1998 in St. Helena by winemaker Samuel Spencer and businesswoman Wendy Roloson. The founders established the winery with an ambition to make premium wines that expressed the character of distinctive vineyard sites rather than relying primarily on large-scale, commodity production. The winery worked with grapes from volcanic and mountainous areas in and around California’s St. Helena and Clear Lake regions, and its portfolio emphasized Rhone and Spanish varieties. The winery’s best-known approach was the production of single-vineyard and estate-oriented bottlings. Its principal varieties included Syrah, Viognier, Tempranillo, Grenache blanc, and Grenache noir. It also made Palaterra, a blend modeled on the style of the Southern Rhone, and produced Zinfandel. This combination gave the winery a profile that was broader than a conventional Napa Valley Cabernet-focused producer and connected its wines to the growing California interest in Mediterranean grape varieties. Spencer Roloson sourced fruit from four principal vineyards. Madder Lake Vineyard, a steep and rocky site directly north of Mount St. Helena in Lake County’s Clear Lake appellation, supplied fruit for some of the winery’s Spanish- and Rhone-variety wines. La Herradura Vineyard was situated east of St. Helena near the base of Howell Mountain. Noble Vineyard, at the foot of the Mayacamas Mountains, was associated with the winery’s Viognier, while Esperanza Vineyard in Clarksburg near Sacramento supplied Grenache blanc. The range of sites reflected an effort to match varieties with locations capable of producing concentrated and distinctive fruit. The winery was also an early client of Enologix, a software-supported laboratory and consulting service that used analytical data to help winemakers shape wines toward particular sensory profiles. The connection illustrated Spencer Roloson’s technically informed, quality-driven approach during a period when data-assisted wine analysis was becoming more visible in the premium California wine sector. Contemporary coverage described the business as a start-up winery and highlighted its Tempranillo program, including vines established from suitcase cuttings brought from Spain. Available reference material documents the winery as a past operation in St. Helena, but does not provide a precise closure date, successor, acquisition history, current owner, or surviving official website. It is therefore best characterized as a defunct or no-longer-operating winery brand rather than an active producer.

Spencer Roloson Winery was established in 1998 in St. Helena, California, by winemaker Samuel Spencer and businesswoman Wendy Roloson. The founders’ stated purpose was to create a premium winery centered on distinctive vineyard sources and varieties that were not limited to the dominant Cabernet Sauvignon model associated with much of Napa Valley. From its beginning, the winery concentrated on Rhone and Spanish grapes, including Syrah, Viognier, Tempranillo, Grenache blanc, and Grenache noir. The winery’s production program drew on several California vineyard sites. Madder Lake Vineyard was a steep, rocky property north of Mount St. Helena in the Clear Lake appellation of Lake County. La Herradura Vineyard lay east of St. Helena at the base of Howell Mountain. Noble Vineyard, positioned near the foot of the Mayacamas Mountains, provided Viognier, while Esperanza Vineyard in Clarksburg near Sacramento supplied Grenache blanc. The use of multiple locations allowed the winery to associate particular varieties with sites considered suitable for their ripening and flavor development. Spencer Roloson emphasized single-vineyard and estate-style bottlings. Its named wines and varietal offerings included Tempranillo, Syrah, Viognier, Grenache blanc, Grenache noir, and Zinfandel. Palaterra represented a Southern Rhone-style blend and broadened the range beyond individual varietal wines. The winery’s Tempranillo program was notable because the vines were reportedly established using suitcase cuttings from Spain, reflecting the founders’ interest in developing Spanish varieties in California conditions. The winery was an early customer of Enologix, a computer-assisted laboratory analysis and consulting service operated by an associate of Spencer. Enologix used analytical methods to help wineries compare and shape taste profiles in relation to highly rated wines. Spencer Roloson’s use of this service placed it among producers experimenting with data-supported winemaking while still presenting its wines through vineyard origin and variety. Contemporary coverage in Wines & Vines in 2002 characterized Spencer Roloson as a start-up winery with a serious quality orientation. A 2006 Sunset wine guide also brought attention to its Tempranillo and the broader emergence of Western American examples of the variety. These references indicate that the winery had achieved recognition within specialist wine coverage during the 2000s. The available references identify Spencer Roloson Winery in the past tense and do not document an active present-day operation. They do not establish the exact year of closure, whether the brand or vineyards were sold, or the identity of any successor. Accordingly, the winery is recorded as defunct, with its historical significance resting on its premium, site-focused California wines and its early commitment to Rhone and Spanish varieties.
