Heartwine

A rare and prized drink, heartwine comes from only a single source: the Cilenei brothers of Curst. These elven wizards have unlocked the means by which the kudzu-like razorvine that swarms over the Lower Planes and Sigil can be fermented into a slightly sour and heady wine. This beverage is well-treasured by gourmands, usually running upwards of 100 gold for a single bottle thanks to its relative scarcity. The secret for making this drink is known only to the Cileneis, and they don't seem especially eager to give up the secret any time soon. Most suspect, however, that magic is involved somewhere in the process.
