This large unique bottle is probably the oldest known bottle of mead (honey wine). 

It was part of the Fukier cellar collection and can be found on old price lists (miody) as the oldest of all offered meads. The price of 180 Zloti is comparable to a Tokaji bottle of vintage 1811. Fukier expert Gabriel Kurczewski explains: 

"During the interwar period, the Fukier winery was also famous for its meads. The 1929 price list listed the following vintages: 1892, 1885, 1879, and the oldest ones, belonging to the Hetman's Cellar collection: 1825, 1792, 176496. According to Henryk Maria Fukier, the oldest meads were collected by Florian Fukier, but the purchase book does not confirm this. Teofil bought honey several times only in the 1880s. His supplier was a well-known Krakow honey producer, J. Wójcikiewicz. Perhaps Fukier began to buy honey in larger quantities only after the popular historical legend of the wine bar had taken shape, arousing guests' interest in this old Polish drink."

Drinkability is unknown the bottle is unopened. Bottle and content have not been chemically analyzed. Some sources claim that old mead can be harmful others state that honey itself can practically be kept forever.
