Simply fill & prepare your portafilter basket like you would for a double espresso shot. Instead of pouring hot water into the top, use cold Tonic Water. Raise the arms and pull your shot as normal. Add ice and top up with more tonic as required (or not!).

Try experimenting with any, yes any carbonated drink. Coca Cola, Lemonade, Beer....... The added carbon dioxide (soda) creates interesting crema !!
