Ostensibly penned by a bard noted for his enjoyment of alcoholic beverages, here is a fine collection of carefully-developed drinks to have on hand whenever the party drops into a tavern.
Each drink has not only a name but Talloow's own tasting notes, a detailed description of the drink and how it's made and even notes of its origin. Some have magical or medicinal properties as well. There is a section on likely costs and how drink may be supplied which is straightforward to relate to the game system that you are using.
How about a refreshing glass of Bumblebutton's Berry Barrel Beer - a halfling brew infused with the flavour of summer berries, or if you prefer white wine try some Gelf's Golden-White. (Gelf makes several other drinks as well, if white wine is not to your taste.) There's Raldenshyre, a red wine, or Red Scoundrel - possibly the best known vodka. There are some racial favourites from both elf and dwarf suppliers and plenty more besides.
The aim of these is just to provide some flavour during a tavern visit, but it would not be too hard to write a plot around them!
