Do I need to sterilise dose bottles before adding essences to the water and should I also use alcohol?
A. Yes on the first bit of your question! I certainly do, though I have known people who don’t and never had any problems. Still, I think it a good idea myself, and especially if you are making a dose bottle for someone other than yourself. As for the alcohol, again I would include it, especially if you are making the dose bottle for someone else, or if the bottle might be exposed to heat or light. Now, if you really hate the taste of Brandy, you can also add drops of essence to juice or coffee to mask the taste. What it so often comes down to though on the latter is personal preference.
