Step 1: Boil 1 cup of water with the sugar, remove from heat and stir in the espresso powder.
Step 2: Add the remaining cold water to the hot syrup, sprinkle in the yeast and pour the whole mess into a plastic soda bottle (it won’t fill the bottle, the extra room is for carbonation gasses).
Step 3: Cap tightly and leave at room temperature for two days then stick in the fridge long enough to chill.
