The traditional Whiskey Sour cocktail dates back to over a century ago. The classic recipe is quite simple: Whiskey, Lemon juice and sugar garnished with a slice of lemon and a cherry. Today’s mixologists now replace the sugar with simple syrup for an easier mix. Then an egg was added for a creamier, frothy element and to make it a little more visually appealing.

This simple, fresh cocktail is being rediscovered and National Whiskey Sour Day (August 25th) is a great way to experience it for yourself. Being a vodka girl, I wasn’t sure what to expect but I can honestly say I love this cocktail! Especially the slushy version – perfect for this Texas heat.

Chris Vetromile, owner of Austin’s VOM FASS, took the time to share his versions of this classic recipe with me with a twist – VOM FASS style. He uses the Calamansi Balsam Vinegar as a crisp refreshing citrus note (replacing the traditional lemon juice) and added the Grapefruit-Lime FassMix to bring out the citrus and add the sweetness.

Ingredients: (Serves 2)

4 ozs VOM FASS American Whiskey

1 oz VOM FASS Calamansi Balsam Vinegar (citrus based)

1 oz VOM FASS Grapefruit-Lime FassMix (simple syrup)

1 egg white (optional)

ice, 2 slices lemon, 2 maraschino cherry


  • Pre-chill cocktail glasses.
  1. Combine Whiskey, Calamansi, syrup and egg white into cocktail shaker.
  2. Shake for 20 seconds. (If not using an gg, add ice and shake until frothy)
  3. Fill shaker with ice. Shake another 20 seconds or until outer shaker is frosty.
  4. Strain evenly into two glasses containing a few ice cubes each.
  5. Garnish with lemon slice on rim and add cherry in glass.

For slushy version:

  1. Pre-chill cocktail glasses.
  2. Combine Whiskey, Calamansi, syrup and ice into cocktail shaker.
  3. Pour all ingredients into blender.
  4. Fill shaker halfway with more ice and add to blender. Blend until slushy.
  5. Pour into two glasses. Garnish with lemon on rim and cherry in glass.
