Ale is a potion which gives the player the Tipsydebuff, increasing melee damage, but lowering the player's defense, for 2 minutes. It can be crafted at a Keg or purchased from the Tavernkeep for 1 each.

Ale sells for 20 and only requires Mugs, which in turn only require 1 Glass, which is crafted from only 2 Sand each. Each unit of 2 Sand is therefore worth 20 if used to craft Ale. Crafting Ale can ultimately be the most profitable means of selling off Sand without incorporating other ingredients.
Since Tipsy is a debuff, it will be removed by the Nurse. Repeatedly consuming Ale and healing at the Nurse can be a fast way to gain the The Frequent Flyer achievement.
