A pub, formally public house (a house “open to the public”, as opposed to a private house), is a drinking establishment fundamental to the culture of Britain, Ireland, Australia, Newfoundland, Canada and New Zealand. In many places, especially in villages, a pub can be the focal point of the community. The writings of Samuel Pepys describe the pub as the heart of England.

Night or nighttime is the period of time between the sunset and the sunrise when the Sun is below the horizon. This occurs after dusk. The opposite of night is day (or “daytime” to distinguish it from “day” as used for a 24-hour period). The start and end points of time of a night vary based on factors such as season, latitude, longitude and timezone.

A drink, or beverage, is a kind of liquid which is specifically prepared for human consumption. There are many groups for drinks. It can be divided into various groups such as plain water, alcohol, non alcoholic drinks, soft drinks (carbonated drinks), fruit or vegetable juices and hot drinks. In addition to fulfilling a basic need, drinks form part of the culture of human society.

A party is a gathering of people who have been invited by a host for the purposes of socializing, conversation, or recreation. A party will typically feature food and beverages, and often music and dancing as well. Some parties are held in honor of a specific person, day, or event, such as a birthday party, a Super Bowl party, or a St. Patrick’s Day party. Parties of this kind are often called “celebrations”. A party is not necessarily a private occasion.

A club is an association of two or more people united by a common interest or goal. A service club, for example, exists for voluntary or charitable activities; there are clubs devoted to hobbies and sports, social activities clubs, political and religious clubs, and so forth.

Nightlife is the collective term for any entertainment that is available and more popular from the late evening into the early hours of the morning. It includes the public houses, nightclubs, discothèques, bars, live music, concerts, cabaret, small theatres, small cinemas, shows, and sometimes restaurants present in a specific area. These venues often require cover charge for admission, and make their money on alcoholic beverages.

A bar is a retail business establishment that serves alcoholic drinks — beer, wine, liquor, and cocktails — for consumption on the premises. Bars provide stools or chairs that are placed at tables or counters for their patrons. Some bars have entertainment on a stage, such as a live band, comedians, go-go dancers, or strippers. Bars which offer entertainment or live music are often referred to as music bars or nightclubs.

Beer is the world’s most widely consumed andprobably the oldest alcoholic beverage; it is the third most popular drink overall, after water and tea. The production of beer is called brewing, which involves the fermentation of starches, mainly derived from cereal grains—most commonly malted barley, although wheat, maize (corn), and rice are widely used. Most beer is flavoured with hops, which add bitterness and act as a natural preservative, though other flavourings such as herbs or fruit may occasionally be included. The fermentation process causes a natural carbonation effect, although this is often removed during processing, and replaced with forced carbonation. Some of humanity’s earliest known writings refer to the production and distribution of beer: the Code of Hammurabi included laws regulating beer and beer parlours, and “The Hymn to Ninkasi”, a prayer to the Mesopotamian goddess of beer, served as both a prayer and as a method of remembering the recipe for beer in a culture with few literate people. Beer is sold in bottles and cans; it may also be available on draught, particularly in pubs and bars. The brewing industry is a global business, consisting of several dominant multinational companies and many thousands of smaller producers ranging from brewpubs to regional breweries. The strength of beer is usually around 4% to 6% alcohol by volume (abv), although it may vary between 0.5% and 20%, with some breweries creating examples of 40% abv and above. Beer forms part of the culture of beer-drinking nations and is associated with social traditions such as beer festivals, as well as a rich pub culture involving activities like pub crawling, and pub games such as bar billiards.

Drinking is the act of ingesting water or other drinks through the mouth. Water is required for many of life’s physiological processes. Both excessive and inadequate water intake are associated with health problems.
