Forty Creek Barrel Select is a blended Canadian whisky, 40% alcohol (ethanol) by volume, 80 proof. It is made with rye, barley and Indian corn (maize).
Each grain is fermented, distilled, and aged separately to produce a "méritage" of single grain whiskies. After distillation using a small-batch, copper pot still,
the whiskies are aged separately 6–10 years in small cask 40-gallon white oak barrels of varying toasting levels. Vintage sherry casks round off some of the
aged whiskies after they are blended, for an additional six months.
