In general, Nikka blended whisky is created from malt whisky made from barley malt in pot stills, and grain whisky made by distilling corn and other grains in a patent (Coffey) still. The main feature of the all-malt process is that top-quality barley malt is used instead of corn in the Coffey still, resulting in a whisky made entirely from malt. All-malt whisky, made from barley alone and blended from malts matured over long periods of time, is blessed with a deep scent and mellow taste.
