Chota Peg

A standard Pitcher/Tankard was marked by wooden nails called pegs or pins in 17th/18th century Great Britain and a "peg" usually marked an individual quantity of drink.

This measure was later adopted to make individual whiskey/brandy containers during the Raj that measured about 2 ounces (about 60 ML). A Chota Peg was half the size, about an ounce or 30 ML
