A jug is a type of container for liquid that is cool. It has an opening, often narrow, from which to pour or drink, and nearly always has some kind of handle. One could imagine a jug being made from nearly any watertight material, but most jugs throughout history have been made from clay, glass, or plastic. Some Native American and other tribes created liquid holding vessels by making woven baskets lined with an asphaltum sealer.

In American English usage, a jug is a large container with a narrow mouth and handle for liquids.

In British English, and generally in English speaking countries outside North America, usage, a jug is any container with a handle and a mouth or spout for liquid.

Beer jug

In certain countries, especially New Zealand and Australia, a 'Jug' refers to a jug (usually plastic) containing exactly 2 pints (just over a litre) of beer. It is usually served along with one or more small glasses from which the beer is normally consumed, although in some student bars it is more common for the beer to be drunk directly from the jug, which is usually served without the accompanying glass. (In the U.S., this is called a pitcher, while in New Zealand and Australia a pitcher usually refers a much larger measure of beer).

Toby Jug

A Toby Jug (not Toby Mug) - also sometimes known as a Fillpot (or Phillpot) - is a pottery jug in the form of a seated person. Typically the figure is a heavily-set, jovial man holding a mug of beer in one hand and a pipe of tobacco in the other and wearing 18th century attire: a long coat and a tricorn hat. The tricorn hat forms a pouring spout, often with a removable lid, and a handle is attached at the rear. Jugs depicting just the head and shoulders of a figure are also referred to as Toby Jugs, although these should strictly be called "Character Jugs".

The original Toby Jug, with a brown salt glaze, was developed and popularised by Staffordshire potters in the 1760s. It is thought to be a development of similar Delft jugs that were produced in the Netherlands. Similar designs were produced by other potteries, first in Staffordshire, then around England, and eventually in other countries.

There are competing theories for the origin of the name "Toby Jug".It was named after the character of Sir Toby Belch in Shakespeare's play, Twelfth Night. He was an intoxicated, jovial man. It was named after a notorious 18th century Yorkshire drinker, Henry Elwes, who was known as "Toby Fillpot" (or Phillpot). It was inspired by an old English drinking song, "The Brown Jug", which paid tribute to Toby Fillpot; the popular verses were first

published in 1761.Toby Jugs are collectible. Indianapolis Colts quarterback Peyton Manning is the most high-profile collector of Toby Jugs, with his collection said to be the largest in North America.

The American Toby Jug Museum is located on Chicago Avenue in Evanston, Illinois.

Puzzle jug

A puzzle jug is a puzzle in the form of a jug. The challenge of the puzzle — to drink the contents without spillage — is often written on the jug. This is certainly impossible to do in the conventional way because the neck of the jug is perforated. Examples of such inscriptions include: Fill me up with licker sweet for it is good when fun us do meet; Gentlemen now try your Skill I'll hold your Sixpence if you Will That you dony drink unless you spill.; Here Gentlemen come try your skill, I'll hold a wager if you will, That you don't drink this liquor all, Without you spill and let some fall.

The earliest example in England is the Exeter puzzle jug — a fine example of medieval pottery in Britain. The Exeter puzzle jug dates from about 1300AD and was originally made in Saintonge, Western France.

Puzzle jugs were popular in homes and taverns. Puzzle jugs were most popular during the 18th and 19th centuries. The quality of pieces varied from quite basic to very fine.

The solution to the puzzle is that the jug has a hidden tube. What looks like the spout is, in fact, one end of a tube which usually runs around the rim of the jug and then down the handle to open inside the jug near the bottom. To obtain the contents, one has to suck on the tube. To make the puzzle more interesting, it was common to provide a number of additional holes on the tube that must be closed off before the contents can be sucked up.

The puzzle jug is a descendant of earlier drinking puzzles, the fuddling cup and the pot crown; the solution to the conundrum being different in each case.
