Sugar

Brown Sugar is a sucrose sugar with a distinctive brown colour from the presence of molasses, it is a partially refined or unrefined sugar containing sugar crystals and residual molasses giving it a distinctive taste and flavour of crystallised molasses or toffee. The taste of dark brown sugar is described as a caramel taste with a deep molasses flavour.
Brown sugar is used in cocktails where a caramel candy or toffee flavour is expected.

Caster Sugar is finely ground granulated sugar. It is not as fine a powdered confectioners' sugar and has a little grit to it. It is somewhere between confectioners' sugar and granulated sugar, and melts in mouth with a mild spicy feel to the tongue

Vanilla Sugar is the regular granulated sugar infused with vanilla flavour, by using vanilla pods and seeds to flavour the sugar. A home made alternative is to use vanilla sticks or pods in a jar of sugar and leave it sealed for 4 weeks to allow the vanilla flavour to infuse. Or to use granulated sugar and vanilla extract and blend in a mixer, although this ends up in powdered sugar.

Water

Water might seem like one ubiquitous ingredient in any alcoholic beverage, and to have no specific purpose other than dilute the alcohol, to prevent irritation and burn, it has more purpose to its presence than it seems.
Water breaks the alcohol molecules and attaches to them and releases the esters that holds the secret to the aroma into the drink and to the nose. Temperature of water is important and although almost all cocktails are served chilled, be sure to understand the role water plays in a drink. Another factor is the quality of water, if you are serious about your cocktail, be sure to use the best neutral tap water or preferably bottled spring water if possible.
