Tasting Notes: Mesquite is used for barbecue wood in southwestern states. In a process very similar to the way peat smoke is used in Scotch Whisky, Santa Fe Spirits makes excellent use of mesquite to smoke their American Single Malt. The delicious mesquite smoke just rolls out of this 6 year old cask, along with apricot marmalade on wheat toast, and the aroma of a leather armchair in a very old library.
