We have chosen a 5:1 ratio as our 'preferred' Dry Martini specification in deference to David Embury who writes of this drink in his The Fine Art of Mixing Drinks, "After extensive experimentation I have arrived at the ratio of 5 to 1 as the proportion most pleasing to the average palate. Personally I like a ratio of about 7 to 1 even better, and I know some who prefer a ratio as high as 10 to 1."
The proportion of gin to vermouth is a matter of taste; some say 5 to 1, others that one drop is sufficient. I recommend you ask the drinker how they would like their Martini, in the same manner that you might ask how they have their steak.
The 'Oliver Twist' choice between an olive (stuffed or otherwise) or a lemon zest twist is traditional and these are the two most common garnishes for a Dry Martini. There are, however, a number of variants. A 'Dickens' is a Martini without a twist, a 'Gibson' is a Martini with two onions instead of an olive or a twist and a 'Franklin Martini' is named after Franklin Roosevelt and has two olives.
There is considerable debate on the origin of the Martini and the best way to make this drink. Detailed information can be found on our Dry Martini page.
