Each year from early February to late March, Napa Valley’s Mustard Season creates an eye-catching blanket of bright yellow mustard flowers across the iconic vineyards, ushering in a new growing season. Carneros Resort and Spa, the 28-acre luxury resort in the picturesque wine region of Carneros, announced a new collection of experiences to celebrate Mustard Season and these vibrant wild blooms that keep the beloved vineyards’ soil strong.
