Title: Cheers!

Cheers!
  • Presented by Jeffrey

2
Categories of Alcoholic Beverages
  • Beer
  • Wine
  • Spirits
  • Hard Liquor

3
Beer
  • Produced through the fermentation of starchy
    material
  • Not distilled after fermentation

4
Ingredients of Beer
  • Water
  • Malt
  • Hops
  • Yeast
  • Clarifying Agent

5
Water
  • Because beer is composed mainly of water, the
    source of the water and its characteristics have
    an important effect on the character of the beer
  • Hard water is more suited to dark styles such as
    stouts or porters
  • Very soft water is more suited for brewing
    light-colored beers, such as pilsners

6
Malt
  • Among malts, barley malt is the most widely used
    owing to its high amylase content, a digestive
    enzyme which facilitates the breakdown of the
    starch into sugars.
  • However, depending on what can be cultivated
    locally, other malted and unmalted grains are
    also commonly used
  • Wheat, rice, oats, and rye, and less frequently,
    maize and sorghum.

7
Malt
  • Malt is formed from grain by
  • soaking it in water, allowing it to start to
    germinate
  • then drying the germinated grain in a kiln

8
Malt
  • Malting the grain produces the enzymes that will
    eventually convert the starches in the grain into
    fermentable sugars

9
Malt
  • Different roasting times and temperatures are
    used to produce different colors of malt from the
    same grain
  • Darker malts will produce darker beers.
  • In most cases, two or more types of malt are
    combined when making modern beers

10
Hops
  • Hops have been used as a bittering agent in beer
  • Used since the seventeenth century

11
Favorable Characteristics of Hops
  • Contribute a bitterness that balances the
    sweetness of the malt,
  • Contribute aromas which range from flowery to
    citrus to herbal,
  • Have an antibiotic effect that favours the
    activity of brewer's yeast over less desirable
    microorganisms and
  • Aid in "head retention", the length of time that
    foamy head created by the beer's carbonation
    agent will last.

12
Yeast
  • Yeast is a fungus that is responsible for
    fermentation
  • A specific yeast is chosen depending on which
    type of beer is being produced
  • Two main strains being
  • ale yeast (Saccharomyces cerevisiae)
  • lager yeast (Saccharomyces uvarum)
  • Yeast will metabolise the sugars extracted from
    the grains, and produce alcohol and carbon
    dioxide as a result.

13
Yeast
  • Wild yeast
  • Most modern fermentations are conducted using
    pure yeast cultures.
  • On average, beers' alcohol content is between 4
    and 6 alcohol by volume
  • can be as low as 2
  • as high as 14 under ordinary circumstances
  • several brewers claim to make beers that are
    upwards of 20.

14
Clarifying agent
  • Some brewers add one or more clarifying agents to
    beer that are not required to be published as
    ingredients.
  • Common examples of these include
  • Isinglass finings, obtained from swimbladders of
    fish
  • kappa carrageenan, derived from seaweed
  • Irish moss, a type of red alga
  • Gelatin.

15
Clarifying agent
  • Since these ingredients may be derived from
    animals, those concerned with the use or
    consumption of animal products should obtain
    specific details of the filtration process from
    the brewer.

16
Brewing process
  • Mashing
  • Sparging
  • Boiling
  • Fermentation
  • Packaging

17
Mashing
  • The malted grains are ground and soaked in warm
    water in order to create a malt extract.
  • The mash is held at constant temperature long
    enough for enzymes to convert starches into
    fermentable sugars.

18
Sparging
  • Water is filtered through the mash to dissolve
    the sugars.
  • The darker, sugar-heavy liquid is called the
    wort.

19
Boiling
  • The wort is boiled along with any remaining
    ingredients (excluding yeast), to remove excess
    water and kill any bacteria.
  • The hops (whole or pelleted) are added, or a hop
    extract is used.

20
Fermentation
  • The yeast is added and the beer is left to
    ferment.
  • After primary fermentation, the beer may be
    allowed a second fermentation, which allows
    further settling of yeast
  • Some brewers may skip the secondary fermentation
    and simply filter off the yeast.

21
Packaging
  • At this point, the beer contains alcohol, but not
    much carbon dioxide.
  • The brewer has a few options to increase carbon
    dioxide levels.

22
Packaging
  • The most common approach by large-scale brewers
    is force carbonation, via the direct addition of
    CO2 gas to the keg or bottle.
  • Smaller-scale or more classicly-minded brewers
    will add extra ("priming") sugar or a small
    amount of newly fermenting wort to the final
    vessel, resulting in a short refermentation known
    as "cask-" or "bottle conditioning".

Raw Beer
25
Wine
  • Wine is an alcoholic beverage resulting from the
    fermentation of grapes or grape juice.
  • The word comes from the Latin vinum - referring
    to both "wine" and the "vine".

26
Wine
  • Wine-like beverages can also be made from other
    fruits or from flowers or grains, even honey.
  • In this sense the word wine is used with a
    qualifier, for example, elderberry wine
  • The word wine by itself always means grape wine.
  • This terminology is often defined by law.

27
Types of Wine
  • Red wine
  • White wine
  • Sparkling wine
  • champagne

28
Spirits (Hard Liquor)
  • A preparation for consumption containing ethyl
    alcohol purified by distillation from a fermented
    substance such as wine, malt, or grain.
  • The term is usually restricted to alcoholic
    beverages.

29
Examples of Spirits
  • Whiskey
  • Brandy
  • Vodka

30
To Be Continued
31
Fermentation
  • Energy-yielding anaerobic metabolic breakdown of
    a nutrient molecule, such as glucose, without net
    oxidation

32
Starch
  • A complex carbohydrate which is insoluble in
    water
  • Starch (in particular cornstarch) is used in
    cooking for thickening sauces

33
Distillation
  • A means of separating liquids through differences
    in their vapor pressures.

34
Hard water
  • Water that has a high mineral content

35
Alcohol by Volume
  • liqueur 15-55
  • liquor (aka spirits) Typically 40 and up,
  • but recently introduced (U.S.) 'light' liquors
    are only 20
  • premium single malt whisky 60
  • neutral grain spirit 95
  • beer 3-6
  • alcopop 4-5
  • cider 5-7
  • barley wine 10
  • wine 12.5
  • port wine 20
  • single malt whisky 40
