Fermented Horse Piss

Basics
The beer of choice for the underaged in Rome, Fermented Horse Piss is a "non-alchoholic brew" that is 1 proof (0.5% ABV), and thus can be sold to men and women under the age of 16. It is a staple drink in inns in small towns, and the going rate is generally 3 SP/pint. It is actually made from the fermented urine of horses, with just enough barley added that it passes for beer among the unintiated. Somewhere, someone is laughing, and he is filthy rich.
