Calvert Extra is frequently referred to as Cocktail Whiskey because of its neutral spirit content. It is made from 70% grain neutral spirits and 30% straight whiskey. The high neutral spirit level makes it very unassuming so that it can be blended with any mixer and not overwhelm the cocktail. It is one of America's top selling blended whiskey. It is bottled at 80 proof (40% ABV) in newly charred white oak barrels. It is sold in glass in 16 oz pint bottles, glass 750ml bottles, glass 1-liter bottles and plastic 1.75L bottles.
