Ratio of Gin to Vermouth
Part of learning how to make a martini is learning about standard, dry, extra dry martinis, and wet martinis. An extra dry martini has just a hint of vermouth, and a dry Martini has slightly less vermouth than the standard recipe calls for. A wet martini can have as much as equal parts of gin and vermouth.
A standard ratio would be:
- 2½ ounces of gin
- ½ ounce of vermouth
However, the ratio can change, so it's best to have a discussion with the person ordering the martini to make sure you are meeting their requirements. Some prefer their martini to be straight gin, or gin with merely a spritz of vermouth. Others like equal parts of each, so it's up to the bartender to discover the drinker's preferences.
