Quiet icons of the Napa Valley, Herb and Jennifer Lamb purchased their house and adjoining seven acres of land in the foothills of Howell Mountain in 1986, immediately digging out the terraces and planting exclusively to Cabernet Sauvignon. Their first vintage in 1990 produced small quantities of exceptional fruit immediately appreciated by winemakers from across the valley, including Ann Colgin, who used the vineyard as the sole source for her signature wine for the next 16 years. Herb and Jennifer first produced under their label in 1997 and continue to limit production to a mere 3-400 cases per year.

The 2015 Cabernet Sauvignon vintage in Napa Valley was exceptional, with the fresh fruit of 2014 and structure of 2013. Winemaker Michael Trujillo calls it "one of the most concentrated, opulent, and expressive vintages we have ever produced." This wine radiates with the typical characteristics of the Herb Lamb terroir: sweet red and blue fruits, liquorice and crushed herbs, cassis, and Baker's chocolate. The 2015 HL Cabernet Sauvignon is big, bold, fruit-forward, and expressive. Layered and focused, this is a jewel of a wine.
