  • 2 ounces gin Old Tom or your favorite gin
  • 1 ounce lemon juice fresh squeezed
  • 1/2 ounce simple syrup
  • 4 ounces carbonated water


  • Fill a cocktail shaker and a tall glass with ice. 
  • Add gin, lemon juice, and simple syrup to cocktail shaker. 
  • Shake for about 10 seconds and strain into ice filled tall glass. 
  • Top with carbonated water and garnish with a slice of lemon. 


  • Gin - to make a classic Tom Collins you should use an Old Tom Gin, which is sweeter style that originated before a London Dry.  We are using a Plymouth Gin, which has more citrus notes.
  • Lemon Juice - fresh squeezed - do not use bottled.
  • Simple syrup - a ratio of half sugar and half water that has been heated until the sugar dissolves.  Can be stored in the fridge for about a month.
  • Carbonated Water  - we use carbonated water that we make in our Soda Stream.
