During my travels in The Witcher 3: Hearts of Stone expansion pack, I came into possession this little item called the 'Bottomless Carafe'.
It's description reads: "Provides an endless supply of hard alcohol. This spirit is distilled from scorpion tails."
This sounds quite useful, as I've spent quite a tidy sum of crowns on various alcohols for alchemy, and I was hoping that this item would allow me an unlimited amount of some ingredients, but alas - when I tried to made things using various alcohols as ingredients, they all seemed to be taken up still. Have Geralt and I been duped? If we have not, how do we go about using this trinket?
