Jocelyn & Lonen produces wines from Napa Valley, the North Coast region celebrated for structured Cabernet Sauvignon and refined white varietals. The winery's portfolio centers on Cabernet Sauvignon in two expressions: a Reserve bottling and a standard release, both drawing on the valley's volcanic soils and diurnal temperature swings. A Chardonnay rounds out the core lineup. The wines have been assessed by major critics including Wine Advocate, Wine Spectator, Wine Enthusiast, Falstaff, and Decanter, reflecting the winery's engagement with the broader wine establishment. The Reserve Cabernet Sauvignon and its standard counterpart anchor the portfolio, with the Chardonnay offering a complementary entry point into the winery's style.
