Session in a cocktail name typically means that a drink is low proof (or at least lower-proof), and perfect for a long session of day-drinking. The session manhattan is a perfect example, inverting the classic template and adding some dry amontillado sherry and dry vermouth for a light, drinkable tipple that wont send you to bed after one glass. If drinks like this are just your speed, be sure to check out the session cocktails book we found it in, from drew lazor and the editors of punch magazine.
