Frequently Asked Questions (FAQs)

1. What Gin goes with grapefruit tonic water?

Palmers Gin It's a gin that has grapefruit in its botanical mix, and we found in our review that it was a lovely, clean gin that a grapefruit garnish really enhanced. We even suggested that you could try it with a grapefruit tonic too. Buy Palmers Gin in the UK from Master of Malt.

2. Why does tonic water taste like grapefruit?

In simple terms, classic tonic water is carbonated water infused with quinine. For added taste sometimes sugar or fruit acids are mixed in. The higher the level of quinine in the water, the more bitter it tastes.

3. Is it OK to drink tonic water every day?

Even three glasses daily should be OK as long as you are not sensitive to quinine. Some susceptible people develop a dangerous blood disorder after even small doses of quinine. Symptoms of quinine toxicity include digestive upset, headache, ringing in the ears, visual disturbances, skin rash and arrhythmias.

4. What Gin goes best with pink grapefruit tonic?

Method: Combine a premium gin (like July's Marylebone Gin) with Fentimans in a large glass filled with ice. Mix well, garnish with a large slice of grapefruit - and enjoy!
