28cm x 62cm Arthur Guinness started brewing ales in 1759 at the St James Gate Brewery,Dublin.On 31st December 1759 he signed a 9,000 year lease at £45 per annum for the unused brewery.Ten years later, on 19 May 1769, Guinness first exported his ale: he shipped six-and-a-half barrels to Great Britain before he started selling the dark beer porter in 1778. The first Guinness beers to use the term 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 single stout, 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 1,138,000 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 twenty 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 2,652,000 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. In the 1930s, Guinness became the seventh largest company in the world. 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 isomerized 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 trialconcerning 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. The company merged with Grand Metropolitan in 1997 to form Diageo. Due to controversy over the merger, 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. Guinness has also been referred to as “that black stuff”. Guinness had a fleet of ships, barges and yachts. The Irish Sunday Independent newspaper reported on 17 June 2007 that Diageo intended to close the historic St James’s Gate plant in Dublin and move to a greenfield site on the outskirts of the city.This news caused some controversy when it was announced.The following day, the Irish Daily Mail ran a follow-up story with a double page spread complete with images and a history of the plant since 1759. Initially, Diageo said that talk of a move was pure speculation but in the face of mounting speculation in the wake of the Sunday Independent article, the company confirmed that it is undertaking a “significant review of its operations”. This review was largely due to the efforts of the company’s ongoing drive to reduce the environmental impact of brewing at the St James’s Gate plant. On 23 November 2007, an article appeared in the Evening Herald, a Dublin newspaper, stating that the Dublin City Council, in the best interests of the city of Dublin, had put forward a motion to prevent planning permission ever being granted for development of the site, thus making it very difficult for Diageo to sell off the site for residential development. On 9 May 2008, Diageo announced that the St James’s Gate brewery will remain open and undergo renovations, but that breweries in Kilkenny and Dundalk will be closed by 2013 when a new larger brewery is opened near Dublin. The result will be a loss of roughly 250 jobs across the entire Diageo/Guinness workforce in Ireland.Two days later, the Sunday Independent again reported that Diageo chiefs had met with Tánaiste Mary Coughlan, the deputy leader of the Government of Ireland, about moving operations to Ireland from the UK to benefit from its lower corporation tax rates. Several UK firms have made the move in order to pay Ireland’s 12.5 per cent rate rather than the UK’s 28 per cent rate. Diageo released a statement to the London stock exchange denying the report.Despite the merger that created Diageo plc in 1997, Guinness has retained its right to the Guinness brand and associated trademarks and thus continues to trade under the traditional Guinness name despite trading under the corporation name Diageo for a brief period in 1997. In November 2015 it was announced that Guinness are planning to make their beer suitable for consumption by vegetarians and vegans by the end of 2016 through the introduction of a new filtration process at their existing Guinness Brewery that avoids the need to use isinglass from fish bladders to filter out yeast particles.This went into effect in 2017, per the company’s FAQ webpage where they state: “Our new filtration process has removed the use of isinglass as a means of filtration and vegans can now enjoy a pint of Guinness. All Guinness Draught in keg format is brewed without using isinglass. Full distribution of bottle and can formats will be in place by the end of 2017, so until then, our advice to vegans is to consume the product from the keg format only for now. Guinness stout is made from water, barley, roast malt extract, hops, and brewer’s yeast. A portion of the barley is roasted to give Guinness its dark colour and characteristic taste. It is pasteurisedand filtered. Until the late 1950s Guinness was still racked into wooden casks. In the late 1950s and early 1960s, Guinness ceased brewing cask-conditioned beers and developed a keg brewing system with aluminium kegs replacing the wooden casks; these were nicknamed “iron lungs”.Until 2016 the production of Guinness, as with many beers, involved the use of isinglass made from fish. Isinglass was used as a fining agent for settling out suspended matter in the vat. The isinglass was retained in the floor of the vat but it was possible that minute quantities might be carried over into the beer. Diageo announced in February 2018 that the use of isinglass in draught Guinness was to be discontinued and an alternative clarification agent would be used instead. This has made draught Guinness acceptable to vegans and vegetarians. Arguably its biggest change to date, in 1959 Guinness began using nitrogen, which changed the fundamental texture and flavour of the Guinness of the past as nitrogen bubbles are much smaller than CO₂, giving a “creamier” and “smoother” consistency over a sharper and traditional CO₂ taste. This step was taken after Michael Ash – a mathematician turned brewer – discovered the mechanism to make this possible. Nitrogen is less soluble than carbon dioxide, which allows the beer to be put under high pressure without making it fizzy. High pressure of the dissolved gas is required to enable very small bubbles to be formed by forcing the draught beer through fine holes in a plate in the tap, which causes the characteristic “surge” (the widget in cans and bottles achieves the same effect). This “widget” is a small plastic ball containing the nitrogen. The perceived smoothness of draught Guinness is due to its low level of carbon dioxide and the creaminess of the head caused by the very fine bubbles that arise from the use of nitrogen and the dispensing method described above. “Foreign Extra Stout” contains more carbon dioxide, causing a more acidic taste. Contemporary Guinness Draught and Extra Stout are weaker than they were in the 19th century, when they had an original gravity of over 1.070. Foreign Extra Stout and Special Export Stout, with abv of 7.5% and 9% respectively, are perhaps closest to the original in character.Although Guinness may appear to be black, it is officially a very dark shade of ruby. The most recent change in alcohol content from the Import Stout to the Extra Stout was due to a change in distribution through North American market. Consumer complaints have influenced recent distribution and bottle changes. Studies claim that Guinness can be beneficial to the heart. Researchers found that “‘antioxidantcompounds’ in the Guinness, similar to those found in certain fruits and vegetables, are responsible for the health benefits because they slow down the deposit of harmful cholesterol on the artery walls.”Guinness ran an advertising campaign in the 1920s which stemmed from market research – when people told the company that they felt good after their pint, the slogan, created by Dorothy L. Sayers–”Guinness is Good for You”. Advertising for alcoholic drinks that implies improved physical performance or enhanced personal qualities is now prohibited in Ireland.Diageo, the company that now manufactures Guinness, says: “We never make any medical claims for our drinks.”
