Gin

Distilled gin is made by distilling white grain spirit which have been flavored with juniper berries. The most common style of gin, typically used for mixed drinks, is London dry gin. London dry gin is made by taking a neutral grain spirit (usually produced in a column still) and re distilling after the botanicals are added.
Gin is added to tonic water to make it more palatable.

Getting the ratio of tonic to gin right is a fine balance.
The ratio of gin to tonic is one part gin to three parts tonic at its weakest. Or one part gin to two parts gin for a normal weight.
