(NBJ) - After acquiring the Echelon Vineyards brand from Diageo Chateau & Estates Wines early this year, Novato-based Winery Exchange has revamped the brand inside the bottle and out. The Novato-based producer of private and national wine, beer and spirits brands for a number of major retailers released a new Collection Series for Echelon, the first of the company’s own national brands. Winemaker Kurt Lorenzi has significantly expanded grape sourcing to include Napa Valley, Russian River Valley and Alexander Valley appellations. The California Series retails for $13–$14 a bottle, and the Collection Series, $15–$18.
