We carefully handcraft all of our wines at our winery in Estes Park, Colorado. We use all handpicked, Colorado-grown grapes. We buy grapes from about a dozen vineyards around Palisade and Paonia on Colorado's Western Slope, plus a vineyard in Burlington on Colorado's Eastern Plains. The Western Slope vineyards range in elevation from about 4000 to 5400 feet, making them some of the highest in the world. Day to night temperature variations typically range from 25 to 30 degrees during the grape maturation months of August and September. The long warm daylight hours of intense high altitude sunlight mature the fruit completely and build the natural sugars. The cool evenings and nights allow the grapes to retain the acids so vital to premium winemaking.  Worden Farms in Burlington provides us with cold-tolerant hybrid grapes we use in our "Oso" blends. The Wordens are truly at the frontier of Colorado grape growing with their vineyards near 4200 feet above sea level, way out in the grassy plains of eastern Colorado.
