A Bota Bag full of wine from the Snobeedle Orchard outside of Waterdeep Proper.  This is the finest wine in the region and extremely expensive. Only a fool would turn down even a taste of such a tasty and potent beverage.

Upon tasting this Damn Fine Wine a character is compelled, if not desperate, to have another taste, and may offer information for another sip. You have advantage on your next charisma based skill check against the character who has tried the Damn Fine Wine. 

The Bota Bag can carry about 10 glasses of the Damn Fine Wine.
