Soda water: Carbonated water (also known as soda water, sparkling water, fizzy water, club soda, water with gas or (especially in the U.S.) as seltzer or seltzer water) is water containing dissolved carbon dioxide gas, either artificially injected under pressure or occurring due to natural geological processes. Carbonation causes small bubbles to form, giving the water an effervescent quality. Common forms include sparkling natural mineral water, club soda, and commercially-produced sparkling water.
Anise liqueur: Anisette, or Anis, is an anise-flavored liqueur that is consumed in most Mediterranean countries. It is colorless, and because it contains sugar, is sweeter than dry anise flavoured spirits (e.g. absinthe). The most traditional style of anisette is that produced by means of distilling aniseed, and is differentiated from those produced by simple maceration by the inclusion of the word distilled on the label. And while Pastis is a similar-tasting liqueur that is prepared in similar fashion and sometimes confused with anisette, it employs a combination of both aniseed and licorice root extracts. Sambuca is essentially an anisette of Italian origin that requires a high minimum (350g/l) sugar content. The liqueur is often mixed with water or poured over ice cubes because of its strong flavour.
