If you don’t have a zester, you can remove the entire peel from the lemon and put it in your pot instead.
The barley flavor in your water will get stronger the longer you leave it to simmer.

Test the flavor of your water, and add more lemon juice if you want.
If you want a slight spiciness to your water, add 1 sprig of fresh oregano along with the peppermint. [11] X Research source
You don’t have to use lemons if you don’t want to.
