Bronze beverage filter from Late Antiquity found in Turkey

A bronze object from late antiquity used to filter beverages has been discovered at the ancient city of Hadrianopolis in northern Turkey’s Black Sea Region. The filter was discovered in the 2024 excavation season in a layer that dates to the 5th century A.D.

The filter is 3.2 inches long, a slim conical shape and is covered with small perforations along its length. It has a suspension loop at the top, indicating it was a valued possession worn on the body for use on the fly, and wear and tear patterns show that it saw a lot of use.

The and draw the liquid through the cone’s perforations. Beverages were often communally shared between several people. Large bowls would be placed in the middle of the group and they would use natural straws like reeds and canes that could be up to three feet long to quench their thirst.

A wide variety of beverages — juice, wine, other fermented drinks — were produced from these ingredients, and they could be pulpy, seedy, sludgy or gritty.
