More about 2019 Merus Napa Valley. Cabernet Sauvignon Merus is Latin for "pure" or "undiluted." The purity behind the winery humbly came to fruition in 1998, with Erika J. Gottl and Mark Herold having crafted the inaugural vintage in their garage behind their house in Napa. The wine won international renown, and in 2007 Bill Foley added Merus to his Foley Family Wines group and restored an old ghost winery into a winemaking facility worthy of the brand. The winery's small size and long-term relationships with many Napa Valley growers allow the team to control many factors in the vineyard, including yield size, pruning, irrigation, and harvest times. The 2019 vintage is 97% Cabernet Sauvignon coming from a unique site in the Coombsville AVA with 3% Petit Verdot, sourced from a selected plot in Yountville, aged 24 months in 100% new French oak giving the already concentrated fruit additional flavor complexity, depth, and a lasting finish.
