A refreshing apéritif with a mouth-salivating bitterness. Makes a Spritz seem bland.

History:

Created in 2017 by Sullivan Doh at the Le Syndicat in Paris, France, who says of his drink, "I was looking for a nice bitter and refreshing drink with a hint of complexity. The gentian of the Suze marries perfectly with the wine and quinine flavour of the Byrrh."

Use a not-overly sugared tonic and well chilled glassware and this is perfect warm weather drinking and a showcase for Suze. Perfectly balanced sweet herbal bitter flavours. Love the supporting role of the Byrrh here, adding a touch of fruit and roundedness.

I used midnight mixers classic dry tonic, which i think is a good quality local alternative to fever tree if you’re in Australia.

Using what I had, this turned out much more moreish than I'd anticipated - Salers, 2:1 blend of Cocchi Americano to Punt e Mes, and Fever Tree Light tonic water. Bold, blush, and bitter up front, drying out in the aftertaste... If this was batched and bottled commercially, I might buy it by the case.

Sounds like reasonable subs. Dubonnet could be another option.

Very nice and refreshing gentian cocktail! I used Bonal in place of Byrrh, and found the base (Suze and Bonal) to be very nice on it's own, but really liked the effect of tonic water - diluting the drink and adding a bit of quinine bitterness.

Thanks, I much appreciate expanding on low alcohol drinks like this one. Schweppes tonic did a good job — the crispness suits it well. One basil top was also an excellent complement. I also agree that it is absolutely possible to play with proportions here — Byrrh and tonic is an excellent combo on its own!

Yes, Byrrh and tonic starting to resemble sloe gin & tonic, with intensely sweet berry/jujube flavours. At least the standard commercial sloe gins.

Nice bitterness but by my taste too sweet for a drink thats supposed to be refreshing.

I used Salers and it is a bit sweetish up front, like a soft drink. But this does mostly vanish in the aftertaste.

Could be the gentian liqueur? I used Suze which is quite bitter, did not find this sweet at all.
