Nikka Coffee Grain Whiskey (750 ML) is $54.99 at CBC Liquors, Westford in Massachusetts — available to order, with pickup and local delivery. Grain whiskies are the base for most blended whiskies throughout the world. Nikka has decided to use the column still (aka Coffey still) rather than the more modern continuous stills to retain more character to their final product. It is quite unusual, however, to bottle and sell this product instead of using it for blending. The grains used here are primarily corn with a splash of barley.
