*A note on sterilising bottles: it's important to ensure that the bottles you use are very clean to avoid contamination of your syrups. There are a few options here whether you want to boil the bottle (be careful!) or put them through a dishwasher. Some may use high proof spirit to sterilise but this may not do the job, however you should be able to find pure food safe alcohol or steriliser at home brew supply stores if that's your thing.
