Rye whisky: Rye whiskey can refer to two different, but related, types of whiskey: American rye whiskey, which is similar to bourbon whiskey, but must be distilled from at least 51 percent rye grain, or Canadian whisky, which is often referred to as (and often labelled as) rye whisky for historical reasons, although it may or may not actually include any rye grain in its production process.
Simple syrup: Simple syrup (aka sugar syrup, or bar syrup) is a basic sugar-and-water syrup used by bartenders as a sweetener to make cocktails. Simple syrup is made by stirring granulated sugar into hot water in a saucepan until the sugar is dissolved and then cooling the solution. The ratio of sugar to water is 1:1 by volume for normal simple syrup, but can get up to 2:1 for rich simple syrup. For pure sucrose the saturation limit is about 5:1 (500 grams (18 oz) sucrose to 100 millilitres (3.5 imp fl oz; 3.4 US fl oz) water).
