Spellbound produces wines from Napa Valley, the North Coast region synonymous with structured Cabernet Sauvignon and bold red varietals. The winery focuses on Petite Sirah and Cabernet Sauvignon—grapes that thrive in Napa's warm days and cool nights, developing deep color and ripe tannins. The Petite Sirah Reserve and standard Petite Sirah bottlings anchor the portfolio, joined by a Cabernet Sauvignon that reflects the valley's signature style. These wines have been assessed by major critics including Wine Enthusiast, Wine Advocate, Wine Spectator, Falstaff, and Decanter, earning ratings in the upper 80s across the range. The consistency of critical attention across the lineup suggests a winery committed to the darker, more muscular end of Napa's varietal spectrum.
