Abstract: A beverage measurement system for a beverage container such as wine bottle includes a series of markings 12 provided on an exterior surface of the wine bottle 14 and precisely positioned to indicate, from the level of beverage remaining in the container, when a measured quantity of the beverage has been dispensed from the container. The measured quantity relates to a particular material content of the beverage in the bottle 14 such as alcohol content, so that a consumer can determine how much alcohol has been consumed. The alcohol content may be represented as the number of “standard drinks”. A drinking vessel is also described.
