Best Buy Under $20! Butternut is the newest offering from Tony Leonardini, whose family owns Whitehall Lane. With premium Chardonnay from Carneros and from western Napa Valley, Tony aged this wine in 100% new French oak, imparting a buttery, nutty roundness to the flavor profile. At under $20 it totally over-delivers. The Butternut Chardonnay is a wine that lives up to its name. It has round, creamy notes, hints of hazelnut and a finish that doesn’t want to quit. Grapes from the regions of Carneros and Coombsville in Napa and Santa Lucia and Arroyo Seco in Monterey broaden the flavor profile of Butternut. The wine spent 14 months on 110 percent new French Oak.
