Glamour lists the sour apple martini as a low-calorie cocktail when made with sour mix, vodka and apple liqueur.
The classic martini is made with gin and vermouth with a green olive or lemon peel, according to The Huffington Post. The martini's origins are lost to history, but its popularity has largely been attributed to Prohibition and the relative ease of manufacturing gin. The martini experienced a resurgence in popularity during the 1990s and has been made famous by iconic figures such as James Bond.
Martinis have several variations, including various flavorings, according to The Huffington Post. Dry martinis are made with little to no vermouth, while wet martinis increase the standard five to one ratio of gin to vermouth. Dirty martinis are made with olive brine or juice, and martinis with a twist substitute lemon peels for olives. Martinis are traditionally served stirred so as not to bruise the gin, but partially due to James Bond, martinis shaken with ice are the more popular option.
