Tonic water

Ingredient type · Lengthener

What it does

Tonic lengthens the drink and leaves a bitter-sweet finish of its own. It makes a Negroni-shaped mix colder, lighter, and slower to drink, but it's far from neutral: the quinine and the sweetness rewrite the end of the drink, especially in the long red and white serves. Too much and the original structure washes out.

In the family

Tonic/soda lengthener

The stretch. A lengthener opens the drink out and drops the concentration. Soda keeps it clean and thin; tonic brings sweetness and a quinine bite.

What it opens up

Americano
Campari and vermouth, no gin, lengthened with soda. Lower strength, easy before food.
