For the uninitiated, bitters are made from botanicals, like aromatic herbs, roots, fruit and bark. These ingredients are steeped into a flavorless alcohol base to create a powerful flavoring. While bitters usually do contain alcohol, you can use a few drops of the same in a non-alcoholic cocktail, which by the end of it will still be considered a non-alcoholic drink, for instance lemon lime & bitters. However, for those who are particular about not using alcohol in their drinks, there are a range of non-alcoholic bitters that one can use.
