Gustave Niebaum's Inglenook Estate, started in 1879, was one of the Napa Valley's first established vineyards and the birthplace of its premium wine industry. Generations after Niebaum's death, the vineyard was sold to Heublein, the wine and spirits monolith, who broke up the land and changed the Inglenook brand from a premium, connoisseur wine to a mass-market jug wine.
