The Auchentoshan Three Wood is also a Single Malt Whiskey from the stables of the Scottish distillery from the Lowlands. Like the other versions, this Three Wood triple distilled. This whiskey is matured in bourbon barrels from American oak and is then poured over in sherry casks of European oak. Besides there are other Auchentoshan whiskey brands that make their whiskey ripen in oloroso casks, however Auchentoshan is one of the few who uses Pedro Ximénez casks. Pedro Ximénez sherry is produced from grapes dried under the Spanish sun. This creates a viscous, pungent and strong wine. The demand for sherry casks is greater than supply, so the taste of the whiskey is highly dependent on the quality of the ex-sherry casks.
