🍸 Ultimate Gin & Tonic FAQ – Everything You Need to Know
1. What exactly is a Gin & Tonic?
A Gin & Tonic (often abbreviated G&T) is a long drink consisting of gin, tonic water, and ice, traditionally garnished with lime or lemon. It’s refreshing, slightly bitter, aromatic, and has become a global classic.
2. Who invented the Gin & Tonic?
The drink originated in British India in the 19th century. British officers were given quinine tonic to fight malaria. Because tonic was extremely bitter, they mixed it with gin (already a favorite among British troops) to make it more palatable. That combination became the Gin & Tonic we know today.
3. Why is quinine important in tonic water?
-
Quinine, extracted from the bark of the cinchona tree, gives tonic its distinct bitterness.
-
Historically, it was used as an antimalarial medicine.
-
Today, the quinine levels in tonic water are much lower—enough for taste but not for medical treatment.
4. What are the main types of gin used in G&Ts?
-
London Dry Gin – Crisp, juniper-forward, no added sugars. (e.g., Beefeater, Tanqueray)
-
Plymouth Gin – Earthy, softer, geographically protected.
-
Old Tom Gin – Sweeter, smoother, historic style.
-
Navy Strength – 57% ABV or higher, bold flavor.
-
Contemporary/New Western – Citrus, floral, or herb-driven (e.g., Hendrick’s with cucumber/rose).
-
Genever – Dutch precursor of gin, maltier and heavier.
5. Which tonic waters are best for a Gin & Tonic?
-
Classic tonics: Schweppes, Canada Dry.
-
Premium tonics: Fever-Tree, Fentimans, Q Tonic.
