Morton William Coutts, OBE (7 February 1904 25 June 2004) [1] was a New Zealand inventor who revolutionised the science of brewing beer. He is best known for the continuous fermentation method.

Beer alcoholic drink

Beer is one of the oldest and most widely consumed alcoholic drinks in the world, and the third most popular drink overall after water and tea. Beer is brewed from cereal grains—most commonly from malted barley, though wheat, maize (corn), and rice are also used. During the brewing process, fermentation of the starch sugars in the wort produces ethanol and carbonation in the resulting beer. Most modern beer is brewed with hops, which add bitterness and other flavours and act as a natural preservative and stabilizing agent. Other flavouring agents such as gruit, herbs, or fruits may be included or used instead of hops. In commercial brewing, the natural carbonation effect is often removed during processing and replaced with forced carbonation.

History

Coutts' German grandfather, Frederick Joseph Kühtze, began brewing beer in Otago, New Zealand in the late 19th century. In 1900 he moved to Palmerston North and set up the family brewery. The brewery was inherited by William Joseph Kühtze, who changed the family name to Coutts during World War I to sound more British. When William Kühtze became seriously ill as a result of the Spanish Flu in 1918, Morton Coutts took over the brewery at age 15 with the aid of his mentor, Conor W. Cary.

Germans are a Germanic ethnic group native to Central Europe, who share a common German ancestry, culture and history. German is the shared mother tongue of a substantial majority of ethnic Germans.

Frederick Joseph Kühtze was a New Zealand brewer. He was born in Cologne, Germany on 8 April 1833.

Otago Region of New Zealand in South Island

Otago is a region of New Zealand in the south of the South Island administered by the Otago Regional Council. It has an area of approximately 32,000 square kilometres (12,000 sq mi), making it the country's third largest local government region. Its population was 229,200 in June 2018.

Continuous fermentation method

In the 1930s, Coutts investigated the nature of yeast which is the most important ingredient in any brewing. Coutts speculated:

Yeast informal group of fungi

Yeasts are eukaryotic single-celled microorganisms classified as members of the fungus kingdom. The first yeast originated hundreds of millions of years ago, and 1,500 species are currently identified. They are estimated to constitute 1% of all described fungal species. Yeasts are unicellular organisms which evolved from multicellular ancestors, with some species having the ability to develop multicellular characteristics by forming strings of connected budding cells known as pseudohyphae or false hyphae. Yeast sizes vary greatly, depending on species and environment, typically measuring 3–4 µm in diameter, although some yeasts can grow to 40 µm in size. Most yeasts reproduce asexually by mitosis, and many do so by the asymmetric division process known as budding.

...that yeast could be properly controlled if you looked on it as a human being with a brain. It has so many enzyme mechanisms to call upon to react to whatever is necessary for its survival. Instead of looking on the final product I always took notice of the yeast as an organism that produced whatever you ended up with.

This led him to create the wort stabilisation process, which resulted in a clearer and consistent wort. He then separated the fermentation into stages. In the first stage the yeast grew and in the second the fermentation began. The yeast was thus encouraged to either grow or produce alcohol. As a result, Coutts created a continuous flow between the two fermentation processes.

Wort is the liquid extracted from the mashing process during the brewing of beer or whisky. Wort contains the sugars, the most important being maltose and maltotriose, that will be fermented by the brewing yeast to produce alcohol. Wort also contains crucial amino acids to provide nitrogen to the yeast as well as more complex proteins contributing to beer head retention and flavour.

Alcohol any organic compound in which the hydroxyl functional group (–OH) is bound to a saturated carbon atom

In chemistry, an alcohol is any organic compound in which the hydroxyl functional group (–OH) is bound to a carbon. The term alcohol originally referred to the primary alcohol ethanol, which is used as a drug and is the main alcohol present in alcoholic beverages. An important class of alcohols, of which methanol and ethanol are the simplest members, includes all compounds for which the general formula is CnH2n+1OH. It is these simple monoalcohols that are the subject of this article.

Other work

Apart from his several patents for the brewing of beer, Coutts was also the first person in New Zealand to broadcast television signals, [1] and the first to send a shortwave radio message to Britain. [1]

Television Telecommunication medium for transmitting and receiving moving images

Television (TV), sometimes shortened to tele or telly, is a telecommunication medium used for transmitting moving images in monochrome, or in color, and in two or three dimensions and sound. The term can refer to a television set, a television program, or the medium of television transmission. Television is a mass medium for advertising, entertainment and news.

Shortwave radio radio frequencies in the range of 1.6-30 megahertz (ITU region 1) or 1.7-30 megahertz (ITU region 2)

Shortwave radio is radio transmission using shortwave radio frequencies. There is no official definition of the band, but the range always includes all of the high frequency band (HF), and generally extends from 1.7–30 MHz (176.3–10.0 m); from the high end of the medium frequency band (MF) just above the mediumwave AM broadcast band, to the end of the HF band.

Note: Obituary is incorrect with regards to the shortwave message to Britain. The first NZ to Britain radio contact was on 18 October 1924 between Frank D. Bell, Z4AA and Cecil W. Goyder, G2SZ and this was the first ever trans-world two-way radio contact. [2]

Brewing production of beer

Brewing is the production of beer by steeping a starch source in water and fermenting the resulting sweet liquid with yeast. It may be done in a brewery by a commercial brewer, at home by a homebrewer, or by a variety of traditional methods such as communally by the indigenous peoples in Brazil when making cauim. Brewing has taken place since around the 6th millennium BC, and archaeological evidence suggests that emerging civilizations including ancient Egypt and Mesopotamia brewed beer. Since the nineteenth century the brewing industry has been part of most western economies.

Homebrewing

Homebrewing is the brewing of beer, mead, and ciders on a small scale for personal, non-commercial purposes. Supplies, such as kits and fermentation tanks, can be purchased locally at specialty stores or online. Alcohol has been brewed on the domestic level since its advent, thousands of years prior to its commercial production, although its legality has varied according to local regulation. In the United States, a permit is required to distill spirits such as moonshine.

Little Creatures is an Australian brewing company based in Fremantle, Western Australia, originally established in 2000 by the original brewers of the Matilda Bay Brewing Company. The name "Little Creatures" is inspired by a song lyric from the Talking Heads Little Creatures album and refers to the live yeast cells that turn the sugars in malt wort into ethanol.

Steam beer is a highly effervescent beer made by fermenting lager yeasts at warmer ale yeast fermentation temperatures. It has two distinct but related meanings:

Adjuncts

Adjuncts are unmalted grains or grain products used in brewing beer which supplement the main mash ingredient. This is often done with the intention of cutting costs, but sometimes also to create an additional feature, such as better foam retention, flavours or nutritional value or additives. Both solid and liquid adjuncts are commonly used.

Allagash Brewing Company

Allagash Brewing Company is a brewery in Portland, Maine.

DB Breweries company

DB Breweries is a New Zealand-based brewing company, owned by Heineken Asia Pacific. Founded in 1930 by Sir Henry Kelliher and W Joseph Coutts, the partners purchased Levers and Co. and the Waitemata Brewery Co. in Otahuhu. Asia Pacific Breweries acquired DB Breweries in 2004, which in turn was bought-out by Heineken International in 2012. The company mainly produces pale lager, whilst its Tui brand is one of the better-known beers in New Zealand, partly due to strong advertising.

Beer is the most popular alcoholic drink in New Zealand, accounting for 63% of available alcohol for sale. At around 64.7 litres per person per annum, New Zealand is ranked 27th in global beer consumption per capita. The vast majority of beer produced in New Zealand is a type of lager, either pale or amber in colour, and typically 4% – 5% alcohol by volume.

Beer style differentiates and categorizes different types of beer

Beer style is a term used to differentiate and categorise beers by factors such as colour, flavour, strength, ingredients, production method, recipe, history, or origin.

Sour mash

Sour mash is a process used in the distilling industry that uses material from an older batch of mash to start the fermentation of a new batch, analogous to the making of sourdough bread with a starter. The term can also be used as the name of the type of mash used in that process, and a Bourbon made using this process can be referred to as a sour mash Bourbon. Despite a common misconception, sour mash does not refer to the flavor of the Bourbon.

History of beer describes the historical development of the brewing

Beer is one of the oldest drinks humans have produced, dating back to at least the 5th millennium BC in Iran, and was recorded in the written history of ancient Egypt and Mesopotamia and spread throughout the world.

The following lists events that happened during 1904 in New Zealand.

Brewery business that makes and sells beer

A brewery or brewing company is a business that makes and sells beer. The place at which beer is commercially made is either called a brewery or a beerhouse, where distinct sets of brewing equipment are called plant. The commercial brewing of beer has taken place since at least 2500 BC; in ancient Mesopotamia, brewers derived social sanction and divine protection from the goddess Ninkasi. Brewing was initially a cottage industry, with production taking place at home; by the ninth century monasteries and farms would produce beer on a larger scale, selling the excess; and by the eleventh and twelfth centuries larger, dedicated breweries with eight to ten workers were being built.

In brewing, attenuation is the percentage that measures the conversion of sugars into alcohol and carbon dioxide by the fermentation process; a more attenuated beer will generally be drier and more alcoholic than a less attenuated beer made from the same wort. The percentage is calculated by comparing weight or specific gravity of the extract before and after fermentation.

Alcohol in New Zealand

Alcohol has been consumed in New Zealand since the arrival of European settlers. The most popular alcoholic beverages are beer and wine. New Zealand has no minimum consumption age for alcohol, however the minimum purchase age is 18.

Beer is produced through steeping a sugar source in water and then fermenting with yeast. Brewing has taken place since around the 6th millennium BC, and archeological evidence suggests that this technique was used in ancient Egypt. Descriptions of various beer recipes can be found in Sumerian writings, some of the oldest known writing of any sort. Brewing is done in a brewery by a brewer, and the brewing industry is part of most western economies.

When drinking beer, there are many factors to be considered. Principal among them are bitterness, the variety of flavours present in the beverage, along with their intensity, alcohol content, and colour. Standards for those characteristics allow a more objective and uniform determination to be made on the overall qualities of any beer.

Tower brewery

A tower brewery is a distinct form of brewery, identified by its external buildings being arranged in the form of a vertical tower.
