High West takes all the work out of preparing this classic cocktail by pre-batching 2 parts of their award-winning High West bourbon and rye whiskies, with 1/2 part demerara simple syrup and 3 dashes of aromatic bitters. They then age the batched cocktail in used rye whiskey barrels to really pull it all together. Just pour over ice and garnish with citrus zest if you are feeling fancy. Delicious!
