Demon Brew is an alcohol beverage in the Lore. It is named either because it was brewed by Demons or because of their predilection for the drink.
Served in Lorean bars and often found in the hands of demons, the drink has delayed effect of at least half an hour (Twice that of real alcohol). It stays in the system for weeks after drinking. Nine shots were enough to make a Valkyrie "legless".
