DIY Tonic Water: Here’s How To Craft Your Own Perfect Mixer

tonic water diy

Tonic water may have had a modest reputation as an anti-malaria medicine. Today, tonic waters are in huge demand as mixers, with some brands producing speciality tonics that cost more than the liquor to choose to mix them with. As with many components of alcoholic beverages, making homemade, customisable tonic water has caught traction among people. 

Why Use Homemade Tonic Water?

Making tonic water at home gives you more control over its flavour. You can decide which ingredients go in it and match it with your favourite gin's flavour profile. You could also try additional aromatics such as lavender or orange peel. You can also experiment with unusual ingredients. Mixing the tonic syrup with sparkling water as needed lets you preserve the tonic syrup for a longer time.


-The tonic syrup needs to be delicious yet subtle, so it enhances and does not overpower the liquor's flavour.
-It needs to be cold extracted as cooked citrus zest tastes well cooked.
-Its flavour profile needs to be barely sweet and pleasantly bitter.

- Use cut cinchona bark rather than the powder as it is easier to filter and provides a bold flavour
