Dunn Vineyards produces 100% Cabernet Sauvignon under two labels: Howell Mountain and Napa Valley. Around 2500 cases of Howell Mountain and about 1500 cases of Napa Valley are made each year. The Howell Mountain Cabernet is from 100% percent Howell Mountain fruit, while the Napa Valley includes up to 15% Napa Valley floor fruit, with the remainder of the fruit coming from Howell Mountain. This floor fruit contributes to the wine’s softer approach, even though the wines usually can be laid down for 15+ years.

The bottles differ in two ways: The Napa Valley has a foil seal, whereas the Howell Mountain has been hand dipped in red wax. The Howell Mountain wine label bears both h the sub appellation Howell Mountain, as well as the appellation Napa Valley while the Napa release only reads Napa Valley. The Napa Valley Cabernet Sauvignon is usually more approachable at a younger age with its softer tannins whereas, the Howell Mountain Cabernet Sauvignon is massive in fruit and tannins.

The 2014 Dunn Cabernet Sauvignon Howell Mountain is a distinguished wine that showcases the rugged elegance typical of its appellation. This Cabernet Sauvignon from Napa's Howell Mountain region has received impressive reviews, with scores consistently in the mid-to-high 90s.

Wine Spectator, awarding it a 97, describes it as having "nose-flaring savory and bay aromas" with a "mouthwatering black core of currant, tar, dried anise, violet, and chestnut notes." The review highlights a "rugged edge" with a "vibrant, lengthy finish," underscoring its potential for aging. Robert Parker’s Wine Advocate also praises the wine with a 96+ score, noting its "mint and thyme" aromatic profile and a "medium to full-bodied palate" that is "beautifully streamlined and silky." Joe Czerwinski of Wine Advocate appreciates the wine's lower alcohol content, crediting Randy Dunn’s decision to reduce it by 1%.

Decanter echoes these sentiments, describing it as "authoritative" and "intense," with a "lovely chassis of fine but firm tannins." The review suggests allowing the wine to mature over a decade to fully develop its complexity. Vinous, also awarding a 96, highlights the wine's "inky dark fruit, chocolate, cloves, incense, graphite, leather, and licorice," crediting its "striking mid-palate creaminess."

Jeb Dunnuck, scoring it 95, notes its "darker, dense, meaty" character, likening it to a "top 2009 Médoc" with "supple, sweet tannins" and "outstanding length." Meanwhile, Jeff Leve describes it as "tannic, tight and demanding time," but anticipates a rewarding experience for those who wait, awarding it a 94.

Overall, the 2014 Dunn Cabernet Sauvignon Howell Mountain is a wine of significant depth and complexity, promising a long aging potential and a rewarding drinking experience.
