Introducing Betty Buzz Tonic Water By Blake Lively! Betty Buzz, a new line of non-alcoholic, sparkling mixers made from clean ingredients. These mixers pair perfectly with any spirit but are also tasty enough to fly solo. Betty Buzz Tonic Water is a light and refreshing American style tonic water, not overly sweet or bitter. Lots of small bubbles makes it the perfect pair for Gin or Vodka... and delicious on its own.
