Guinness

Guinness is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Guinness rather than just read about it. In short: Guinness ( ) is a stout that originated in the brewery of Arthur Guinness at St. James's Gate, Dublin, Ireland, in the 18th century.

Key takeaways

  • Guinness belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Guinness to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Guinness from memory before moving on to harder problems.

Reference excerpt

Guinness ( ) is a stout that originated in the brewery of Arthur Guinness at St. James's Gate, Dublin, Ireland, in the 18th century. It is now owned by the British multinational alcoholic beverage maker Diageo. It is one of the most successful alcohol brands worldwide, brewed in almost 50 countries, and available in over 120. Sales in 2011 amounted to 850,000,000 litres (190,000,000 imp gal; 220,000,000 U.S. gal). It is the highest-selling beer in both Ireland and the United Kingdom. The Guinness Storehouse is a tourist attraction at St. James's Gate Brewery in Dublin, Ireland. Since opening in 2000, it has received over 20 million visitors. Adopted in 1862 by the incumbent proprietor, Benjamin Lee Guinness, the Guinness harp motif is modelled on the Trinity College harp (which is the national symbol of Ireland), with the right-facing harp registered as a trademark for Guinness in 1876. Guinness's flavour derives from malted barley and roasted unmalted barley. The unmalted barley is a relatively modern addition that became part of the grist in the mid-20th century. For many years, a portion of aged brew was blended with freshly brewed beer to give a sharp lactic acid flavour. Although Guinness's palate still features a characteristic "tang", the company has refused to confirm whether this type of blending still occurs. The draught beer's thick and creamy head comes from mixing the beer with nitrogen and carbon dioxide. Guinness moved its headquarters to London at the beginning of the Anglo-Irish trade war in 1932. In 1997, Guinness plc merged with Grand Metropolitan to form the multinational alcoholic-drinks producer Diageo plc, based in London.

History

Arthur Guinness started brewing ales in 1759 at the St. James's Gate Brewery, Dublin. On 31 December 1759, he signed a 9,000 year lease at £45 per annum for the unused brewery, and it would become one of the largest in the British Empire. Arthur Guinness started selling porter in 1778. The first Guinness beers to use the term "stout" were Single Stout and Double Stout in the 1840s. Throughout the bulk of its history, Guinness produced only three variations of a single beer type: porter or stout (single, double or extra) and foreign stout for export. "Stout" originally referred to a beer's strength, but eventually shifted meaning toward body and colour. Porter was also referred to as "plain", as mentioned in the famous refrain of Flann O'Brien's poem "The Workman's Friend": "A pint of plain is your only man." Already one of the top-three British and Irish brewers, Guinness's sales soared from 350,000 barrels in 1868 to 779,000 barrels in 1876. In October 1886, Guinness became a public company and was averaging sales of 1.138 million barrels a year. This was despite the brewery's refusal to either advertise or offer its beer at a discount. Even though Guinness owned no public houses, the company was valued at £6 million and shares were 20 times oversubscribed, with share prices rising to a 60 per cent premium on the first day of trading. The breweries pioneered several quality control efforts. The brewery hired the statistician William Sealy Gosset in 1899, who achieved lasting fame under the pseudonym "Student" for techniques developed for Guinness, particularly Student's t-distribution and the even more commonly known Student's t-test. By 1900 the brewery was operating unparalleled welfare schemes for its 5,000 employees. By 1907 the welfare schemes were costing the brewery £40,000 a year, which was one-fifth of the total wages bill. The improvements were suggested and supervised by Sir John Lumsden. By 1914, Guinness was producing 2.652 million barrels of beer a year, which was more than double that of its nearest competitor Bass, and was supplying more than 10 per cent of the total UK beer market. When World War I broke out in 1914, employees at Guinness St. James Brewery were encouraged to join the British forces. Over 800 employees served in the war. This was made possible due to a number of measures put in place by Guinness: soldiers' families were paid half wages, and jobs were guaranteed upon their return. Of the 800 employees who fought, 103 did not return. During World War II, the demand for Guinness among the British was one of the main reasons why the UK lifted commerce restrictions imposed in 1941 to force Ireland into supporting the Allied Powers. Before 1939, if a Guinness brewer wished to marry a Catholic, his resignation was requested. According to Thomas Molloy, writing in the Irish Independent, "It had no qualms about selling drink to Catholics but it did everything it could to avoid employing them until the 1960s." Guinness thought they brewed their last porter in 1973. In the 1970s, following declining sales, the decision was taken to make Guinness Extra Stout more "drinkable". The gravity was subsequently reduced, and the brand was relaunched in 1981. Pale malt was used for the first time, and isomerised hop extract began to be used. In 2014, two new porters were introduced: West Indies Porter and Dublin Porter. Guinness acquired The Distillers Company in 1986. This led to a scandal and criminal trial concerning the artificial inflation of the Guinness share price during the takeover bid engineered by the chairman, Ernest Saunders. A subsequent £5.2 million success fee paid to an American lawyer and Guinness director, Tom Ward, was the subject of the case Guinness plc v Saunders, in which the House of Lords declared that the payment had been invalid. In the 1980s, as the IRA's bombing campaign spread to London and the rest of Britain, Guinness considered scrapping the harp as its logo. In 1997 the company merged with Grand Metropolitan to form Diageo. The company was maintained as a separate entity within Diageo and has retained the rights to the product and all associated trademarks of Guinness.

The Guinness brewery in Park Royal London, closed in 2005. The production of all Guinness sold in the UK and Ireland was moved to St. James's Gate Brewery, Dublin.

Worked examples

Example 1 — a first encounter with Guinness

Start with the simplest possible case. Write down what Guinness claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Guinness before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Guinness ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Guinness

In research
Guinness appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Guinness in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Guinness is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1759 establishments in Ireland, Beer brands of Ireland, Diageo beer brands, so understanding it makes those chapters shorter.
In everyday life
Look for Guinness outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
