A carpenter can produce 4 barrels in a day's work using 1 bushel of wood and 1 iron ore at his workshop.
One can be sold or bought between 7 and 22,95 ecus.
Each barrel subtracts 2 points of load from one's personal inventory capacity.
The barrel is part of a finished product in use by winemakers, cidermakers and distillers so that they can stock and sell their production of wine, hard cider, whisky and whiskey.
It is therefore not recommended to buy if your character is not a winemaker, cidermaker, distiller, traveling merchant, mayor or trade minister.
