Best Tonic Water for Gin and Tonic

Well it’s about time The Gin Geek discusses the best mixers for your Gin!


We may have had one or two sociable drinks by this point.

Picture the scene, it’s one of those lovely (albeit somewhat rare) sunny days in Henley-upon-Thames, England, and am sat relaxing on the grass at the Rewind South 2016 (80’s music festival) with my cousin Samantha.

We were just deciding whether to see the next band or grab a bite to eat, when a young lady approaches us with a tray or drinks, and asks would we like to try the best tonic water for gin and tonic?

A bit of a tall statement I thought, however it would be rude of us not to, so we of course accepted. The young lady in question was promoting Fever Tree tonic water, they had the excellent slogan of ‘If 3/4 of your Gin & Tonic is the tonic, make sure you use the best’. I must say that phrase has really stuck with me, and I have been big fan of Fever Tree products ever since.

Fever Tree Tonic Water

Here is what Fever Tree have to say about Mixers… Wise words indeed!

Charles Rolls & Tim Warrillow joined forces to form Fever-Tree after they discovered that with the majority of suppliers, their tonic waters were preserved with sodium benzonate or such like, plus contained cheap aromatics and artificial sweeteners.

After a lot of research to find the finest ingredient’s and work through a number of recipes, Charles and Tim were finally happy to release their first bottle of Fever-Tree Indian Tonic Water to the now very thankful Gin loving public, myself included.

Fever-Tree Indian Tonic Water

An award winning tonic that blends quality botanical oils with spring water and quinine. This is the standard by which all other tonic waters are judged in my opinion.

Colour & Taste

Clear, well carbonated, clean & crisp with a hint of citrus coming from the orange, and slight bitterness from the quinine. Perfect Indian Tonic Water.


Quinine, Cane Sugar, Spring Water, Bitter Orange.

Best Served

Tanqueray No. Ten Gin with Fever-Tree Indian Tonic Water, ice, and a curl of lime rind.

Aromatic Tonic Water

A blending of the slight bitterness of angostura bark with botanicals such as cardamom, pimento berry and ginger makes for a distinctive tonic water that will enhance the flavours on the Gin itself. A ‘tailor made’ tonic water for Pink Gin lovers.


Quinine, fresh green ginger, cane sugar, spring water, bitter orange, angostura bark, cardamom, pimento berry.

Colour & Taste

Lovely pink hue that is the perfect tonic for any Pink Gin, and nicely carbonated. It’s sweet with subtle hint of orange bitters, citrus tones, and a mild but noticeable snippet of spice at the end. As an alcohol free Gin and Tonic alternative, I drink this on its own with ice and some lemon or lime rind (cut off the flesh).

Fever-Tree Mediterranean Tonic Water

Fever-Tree have really come up with something interesting here, and for that they deserve a pat on the back as I feel its paid off. Using essential oils from the flowers, fruits and herbs from Mediterranean shores with quality quinine.

Mediterranean Tonic water is a great mixer for both Gin and Vodka, and although I am a bit still stuck in my ways and by default will go for Indian Tonic Water for a G&T, this is a close second!


Quinine, Lemon Thyme, Rosemary, Cane Sugar, Spring Water.

Colour & Taste

Clear, well carbonated, clean & crisp with a hint of citrus and herbs, and only a slight bitterness from the quinine. Makes a completely different drink than with Indian Tonic water, well worth a try if you fancy a change, or don’t like the bitterness of Indian Tonic water.

Fever-Tree Elderflower Tonic Water

A light and subtle character, the delicate and sweet flavour of elderflower is perfectly balanced by the soft bitterness of the quinine. Providing a summery twist to the classic gin and tonic, the refreshing floral flavour works equally well as a sophisticated soft drink.


Quinine, Elderflowers, Cane Sugar, Spring Water.

Colour & Taste

Clear, nicely carbonated, smooth & crisp with a hint of floral and citrus, and a slight bitter aftertaste from the quinine.

Best Served

Hendricks Gin with Fever-Tree Elderflower Tonic Water, ice, and a slice of cucumber or mint.

I prefer mint, as cucumber should go in very dainty sandwiches and be eaten whilst wearing a monocle and saying phrases line ‘By Jove Jeeves’ and ‘Tally Ho’.

Fever-Tree Ginger Ale

OK, it’s’s not a tonic water, but its heaven. Made by blending three ginger oils with spring water make for a high quality ‘grown up’ Ginger Ale. Works amazingly with Brockmans Gin, see ‘Best Served’ below. Again, this is another mixer that’s lovely to drink on its own.


Fresh Green Ginger, Nigerian Ginger, Cochin Ginger, Cane Sugar, Spring Water.

Taste Notes

Rich golden colour, great carbonation balance, with citrus aromas and just the right amount of the ginger twang (yes, I said twang).

Best Served

Brockmans Gin with Fever-Tree Ginger Ale, ice, pink grapefruit peel, and a few blueberries. I would love you to try this combination and send me your feedback, it’s certainly one of my favourites.

So that about wraps it up for today’s low down on Fever-Tree mixers, and why Fever-Tree has become in my humble opinion, the best tonic water for Gin & Tonic. It is now one of the most popular suppliers of premium mixers around the world. The bar has now been set very high (about time too!), and I thoroughly recommend Fever-Tree for all your Gin mixer requirements.

I hope you found this review was helpful, and if you have any mixer related comments, or have a different brand you would like to bring to my attention, then please leave a comment below.

  1. I like Elderflower. Overall good list. Here is my views
    As a tonic lover I can go and rate them all
    Schweppes – good when theres no other tonic as it still tastes OK although it is cloying. Sweet and a synthetic cinchona flavoring that is not real quanine
    Canada Dry – The weakest, cheapest brand
    Fever Tree is better by miles and I have tried the following. The Indian is easily available and is good, plenty of cinchona or quinine flavor that is natural. Although its downfall is that it is a bit sweet, although only subtly
    Mediterranean is the best – perfect bitter-sweet balance with the quinine tonic flavor and a little sweetness only. A good one because it means you can kick the lime and lemon out of the G&T with this one as we did. The best one in a gin as its flavour is retained even when mixed with it
    Elderflower – wins with the Mediterranean although it tends to get lost in the gin. I would actually rather drink it straight up or as a more tonicized gin and you will need more. It is not sweet however so using even a reasonable amount won’t add much sugar at all
    Light – this one is least sweet although it is a bit like tonic flavored soda water. Not enough flavor. I have yet to try the other ones

    • Hello John

      Thank you for taking the time to comment, really appreciate your views on tonic as its just as important as the Gin, if not more so dare I say. My goodness, Canada Dry, have not had that in ages. Fever Tree Indian is the defacto for me, although like you, I am very partial to the Elderflower even without the Gin.

      I guess or me it depends where I am, for example I was out with friends & family to see my cousin play in her band last week (she was fab!), and unfortunately all the establishment were serving was either Gordon’s or their House Gin (worryingly just had the word ‘GIN’ on the bottle), plus the only tonic choice was Schweppes. Maybe it was a mind thing but I preferred their house Gin lol, and after 4 of them I don’t think I could tell the difference between .

      As an unrelated side note, try Sharish Blue Magic Gin if you have not already done so. Agree it looks a trifle tacky, however with Fever Tree Indian tonic and ice it was outstanding.

  2. My go to mixer is diet ginger ale, yes – Canada Dry. I’ve cut most sugar from my life. Are there any sugar free mixers you recommend?
