3Introduction What is beer?
- An alcoholic beverage made by brewing and
fermentation from cereals, usually malted barley,
and flavored with hops and the like for a
slightly bitter taste. - Source dictionary.com
- Global revenue of 294.5 billion in 2006
- Thats 133 billion Litres worth
- Beer is found all over the world
- Some of you may have even had beer!

5Beer in the ancient world
6Beer in the ancient world
- Beer dates back to around 6th century BCE
- Most likely the result of spontaneous
fermentation of breads - Beer was an important beverage in ancient Egypt
and Mesopotamia and was used in religious
ceremonies and as gifts to the pharaoh - 30,000 gallons a year was offered to the gods
- Even the dead were buried with beer!
- A medical document written around 1600 BCE lists
700 prescriptions, around 100 of which contain
beer - The Greeks felt beer was an integral part of a
healthy diet - They spread the art of brewing to the Romans, who
spread it to Britannia
7Beer in the medieval world
8Beer in the medieval world
- Monks built the first breweries, and were
pioneers of the hotel offering shelter, food,
and drink to traveling pilgrims - Beer was generally brewed by women
- They were cooks, and beer was considered
food-drink - Beer was preferred over water, since it was often
more sanitary - Beer also provided much needed calories to the
generally low-calorie diets of the day - Though popular, beer was disdained by science
because Ancient Greek physicians had no
experience with beer - The use of hops in beer was written about in 822,
but perfected in Germany in the 13th century - Until then it was difficult to establish the
right proportion of ingredients - Hops allowed the beer to be exported
9Beer in early modern Europe
10Beer in early modern Europe
- By the 15th century, almost half of the cargo
taken across the North sea and Baltic sea were
barrels of beer - Beer making changed from a family activity to an
artisan activity - Ale and beer became synonymous in the 16th
century - William Shakespears father was an Ale Connor
- Sat on ale in leather breeches to test for sugar
- In the 16th century, The Dean of St Pauls
invented the beer bottle - Also in the 16th century, Benjamin Franklin
recorded the daily consumption in a London
printing house to be five pints per employee - Lager is discovered after beer stored in cool
caverns
11Beer in the Industrial Revolution
12Beer in the Industrial Revolution
- The advent of the steam engine allowed for the
industrialization of beer - Prior to the late 1700s, malt was dried with
fires made from wood charcoal, straw, or coke - They were not able to shield the malt from smoke,
giving the malt a smoky flavour - Wood smoked malt was supposedly horrible
- Using a hydrometer, brewers could calculate the
yield from different malts - Pale malts gave the highest output, and coloured
malts were added in small amounts to achieve the
correct colour - The use of a drum roaster allowed for the
creation of very dark, roasted malts, giving rise
to stouts
13After the Industrial Revolution
- Bootleggers watered down their beer to increase
profits during prohibition. This practice changed
the American palette, which prefers milder beers
to this day - In Europe, live beer (real ales) have become
popular - Unfiltered, unpasteurized brews containing live
yeast - Develop flavour and character over the course of
several decades as opposed to several weeks or
months
14Ingredients
- Water
- Or H2O
- Starch
- The most important ingredient for providing
character to a beer - Most common source is malted grain
- Grain is soaked to expedite germination, then
dried and roasted in a kiln - Hops
- From the flower of the hop vine
- Provide bitterness to balance the sweetness of
the malt - Add floral, citrus, and herbal aromas and
flavours - Antibiotic properties favour brewers yeast over
less desirable microorganisms - Preservative!
- Yeast
- Responsible for fermentation (metabolizing sugars
from the malt) - Can influence the flavour of the beer
- Clarifying Agent
- Used to precipitate any leftover proteins after
brewing - Spices and fruits
- Love
15Brewing
- Mashing
- The temperature of a water/starch mixture
(usually malted barley) is raised to activate
enzymes which break down the starch into
fermentable sugars - Sparging
- The mash is rinsed through a porous barrier
called a lauter-tun that allows the fermentable
liquid to pass, but not the grain. - This liquid is called the wort
- Boiling
- The wort is then boiled to steralize it, and
remove the water so that only the sugars and
other components remain. - Hops are added at this stage
- The longer the hops boil, the more bitterness
they add, but the less flavour they add - Fermentation
- The boiled wort is cooled and put into a
fermentation vessel along with yeast. The mixture
is allowed to ferment anywhere from a week to a
month. Yeast and sediment settle, and the
resultant clear liquid is the beer. - Packaging
- Beer is put into the vessel in which it will be
served. - It can be carbonated artificially
- It can also be carbonated naturally by adding
small amounts of fresh wort, sugar, and/or yeast
16Tasting
- Aroma
- Can come from the malt, strength of the hops,
alcohol, esters, or other ingredients - Flavour
- From the type and amount of malt used, flavour of
the yeast, and the bitterness of the hops - Appearance
- Colour, clarity, nature of the head
- Mouthfeel
- The feel of beer in the mouth, both from the
thickness of the beer and from carbonation.
Carbonation can cause the beer to seem creamy or
prickly - Strength
- Original gravity the amount of fermentable
material (density of the wort) - Final gravity the density of the beer after
fermentation - In dry beer, more sugar is converted to alcohol
during fermentation, non-dry beer is thus sweeter - Alcohol by volume
17Pop quiz!
- What is the difference between beer, ale, and
mead?
18Pop quiz!
- Mead is made from honey, water, and yeast
- Honeymoon is derived from the month long supply
of mead given to a newlywed couple in order to
help conceive a child - Beer and ale are the same thing
- Originally ale meant beer with no hops
19Types of Beer
- Ales
- Use top-fermenting yeast which is unable to
metabolize certain sugars. This results in a
fruitier, sweeter beer. Top fermenting yeast
rises to the top of the vessel during
fermentation. - Fermented at higher temperatures than lager beer
(1523C ) - Ale yeasts at these temperatures produce
significant amounts of esters resulting in a
flowery, fruity aroma - Pale ale
- Brewed using a pale barley malt. Hop levels can
vary. - Dark ale
- Brewed using dark roasted barley malts. Also
called stout. - Irish red ale
- The red colour comes from the use of roasted
barley. Has a malty, caramel flavour. - Cream ale
- Brewed to be light in colour, hop and malt
flavour is subdued. - Brown ale
- Brewed with a darker barley malt, lightly hopped
and fairly mildly flavoured with a slightly nutty
taste.
20Types of Beer
- Lager
- The most commonly consumed style
- Fermentation occurs at around 7-12C using a
bottom fermenting yeast - Fermentation phase
- Then cooled at 0-4C
- Lagering phase
- The lager clears and mellows
- Inhibits the production of esters, resulting in a
crisper (less fruity) tasting beer - Has more fizz than ale
- Premium Lager? No such thing.
21Types of beer
- Lambic
- Brewed using wild, not cultivated yeasts. This is
the style of beer people brewed until the middle
ages. - This process is called spontaneous fermentation.
Most cereals can undergo spontaneous fermentation
by being exposed to the air.
22Midterm 1 Match the glass types to their picture
- Pilsner glass
- Pint glass
- Beer Stein
- Wheat beer glass
- Yard glass
23Midterm 1 Match the glass types to their picture
- Pilsner glass
- For pilsner and light beers
- Pint glass
- Anything goes!
- Beer stein
- The lid keeps the beer in the glass while you
sing a hearty tune - Wheat beer glass
- The shape allows for greater production of foam,
and exposure to air when tilted back - Yard glass
- 1 yard long, 3 pint volume. Used in drinking
games (drink the whole thing without pausing for
breath!)
24Nutrition
- The good
- Beer has no fat! Oil would ruin the head and
mouthfeel. Some believe that overeating and a
sedentary lifestyle cause the infamous beer
belly and not the product itself. (bar food
anyone?) - Moderate consumption of beer results in a
decreased risk of cardiac disease, stoke, and
cognitive decline - Brewers yeast is a rich source of nutrients
including magnesium, selenium, potassium,
phosphorus, biotin and B-vitamins - The bad
- Heavy consumption of alcohol can lead to liver
disease, pancreatitis, and gout - The ugly
- Ugly people can look good when youve had too
many beers
