A Vodka and Soda is a bit of an art. Add a simple blackberry syrup, and the parts get skewed. Just remember this; balance and proportions are key. A good ratio is around 1-part vodka to 4-parts soda. If using a simple syrup, 1-part vodka to 1-part simple syrup to 3-parts soda.

Simple syrups keep in the fridge for about two weeks. I like to store mine in pretty decanters and carafes that go from refrigerator to table. These are especially nice when passing a pitcher of iced tea that gets a simple syrup sweetener, or for serving personalized carafes of wine.

A Vodka & Soda is a deceivingly uncomplicated cocktail to put together. There is, however, a wrong way to mix vodka with seltzer.

It can be used over vanilla ice cream as a unique dessert, in cocktails such as this one, and makes a thirst-quenching beverage when mixed with fresh lemonade. My herb garden did so incredibly well this summer, that I am now trying to come up with more compound butters and simple syrups to use them in. Rosemary is an especially strong herb. It meets its match when up against blackberry though. Their union is ethereal.

  • 1 cup fresh, very ripe blackberries frozen may be substituted
  • 1 sprig fresh rosemary, plus more for garnish
  • ¼ cup sugar
  • ½ cup water
  • 1 ½ ounces floral or citrus-flavored vodka I am using Kettle One Grapefruit & Rose
  • ½ ounce freshly squeezed lime juice
  • 3 ½ ounces seltzer


  • Muddle blackberries, rosemary, and sugar in a small saucepan until almost smooth. Add water and bring to a simmer over medium-high heat. Cook, stirring occasionally, until fragrant, about 5 minutes.
  • Set a swath of cheesecloth in a colander over a heatproof bowl. Strain the mixture into the cheesecloth, pressing on the solids to extract as much juice as possible. Refrigerate until cool, about 30 minutes.
  • Once syrup has cooled, transfer to a small carafe or beaker.
  • Combine 1 ounce of the syrup and the 1/2 ounce lime juice in a glass. Next, add the vodka. Add fresh ice cubes and top with seltzer. Garnish with more rosemary and a whole single blackberry, if desired.
