Prepare the bottle by filling it with boiled water, thereby steralizing the bottle. Pour out the boiled water and leave it drain any excess water.
Add the Sugar and the Water to the Saucepan and while stiring the ingredients over a gas or electric stove. Once all of the sugar has disolved and the syrup has been brought to the boil, reduce the heat and allow it to simmer for 5 minutes.
Using the funnel, carefully pour the simple syrup into the steralized bottle. Leave to cool before adding the lid.
