Woodford Whiskey Double Oak is made from corn, rye, barley malt and clear spring water. Using five to seven yeasts in a process of acid fermentation, a triple distillation takes place in copper stills. The whisky is then stored for about seven years in white oak casks, which have been produced and charred in the in-house kitchens. However, at Woodford Reserve, only Master Distiller Chris Morris decides how long the cask will mature and the exact time of discharge. The bourbon then matures for nine months before being bottled. This gives Bourbon Double Oaked a sweeter and smoother flavour.
