Analyze Drink
(Divination)

Range:  0
Components:  S
Duration:  Instantaneous
Casting Time:  3
Area of Effect:  One drink
Saving Throw:  None

This spell requires the caster to sip a drink of any sort. The spell will then analyze all the components of the drink and make them known to the caster.
The various liquids which make up the drink are revealed specifically, as well as the proportions in which they are existant. Specific brews, vintages, or brands (if applicable) are known exactly, and any dilution of the drink with water is also revealed.
Since the casting requires actually tasting the drink, it is not really useful in safely identifying poisons (although the caster will instantly know the kind of poison that just hit him!).
