Wine grapes have been grown in several counties of Colorado since the end of the last century. A renewed interest in wine grape cultivation was initiated during the mid-70's and the most dramatic growth of the Colorado Wine Industry is occurring this decade. Since 1990, vineyard acreage has increased from 242 to over 400 acres. State production levels have also increased from 107 tons to 755 tons and mature vineyards in 1997 averaged 3.4 tons/acre
