What you have there is a type of Brandy rather than a Whisky...
Looks like your label says: "Eau de Vie de Dantzic"
An "Eau de Vie" (aka Eaux-de-vie) is simply a brandy without any fruit in the
liquid - Eau's are traditionally colorless, however the Eau de Vie de Dantzic
[often spelled Dantzick] also contains macerated Lemon Peel, with Mace or
Cinnamon, giving it a unique flavoring & color.
Eau de Vie de Dantzic has been around since at least 1827, and was first
described as a 'gold-leaf infused brandy'; often drank as a cordial or used in
the making of fine jellies.
