All the drinking guidelines and recommendations refer to one or more standard drinks. What is a standard drink?
A. A standard drink, in Australia , refers to an alcoholic drink containing 10gm of ethanol or ethyl alcohol. This definition was adopted by Canberra and the wine industry to help people monitor and control their alcohol consumption. For a 12% v/v alcohol wine, one standard drink is approximately 100ml, where a 750ml bottle of this wine would carry a comment stating, This bottle contains approximately 7.5 standard drinks. For a 17-22% v/v alcohol fortified wine, such as a port or liqueur, one standard drink is approximately 60ml. Many bars, clubs, pubs and restaurants are now serving wine in wine glasses that have approximately 100ml, or one standard drink, marked on the glass. Some establishments still serve wine in larger glasses. One of these glasses may be equivalent to one and half or even two standard drinks.
