Carneros, known predominantly for its Pinot Noir and Chardonnay production, bridges the Sonoma-Napa County border. It’s the Napa side that I have a hard time with. With some of the region’s coolest climates the Pinot Noir here seems to be harsher, tighter, spicier — whereas I tend to favor my full-bodied, fruit-forward Russian River Pinots. But when it comes to Chardonnay, I like a bit more life, intrigue, rusticity, flavor. That same Carneros cooling effect gives the Chardonnays from the region just that: a marked acidity, minerality, and earthiness that shines right through — from stem to stemware.
