Beer is an alcoholic beverage made from grains like barley that is flavored with hops. The brewing process has been traced back thousands of years to ancient Babylon and Egypt. Beer styles like ale and lager developed, distinguished by using top-fermenting or bottom-fermenting yeast. The key ingredients of beer - barley, hops, yeast, and water - each contribute important flavors and characteristics to the final product. The production process involves steeping, malting, mashing, boiling, fermenting and conditioning the beer over several weeks. Common beer types include pilsner, lager and ale, which vary in color, body and alcohol content.

2. DefinitionDefinition
• Beer is defined as a fermented,
alcoholic beverage made from barley,
wheat, rice etc. & flavoured with hops.

3. HistoryHistory
• There is evidence that brewing process was
established in Babylon in 6000 B.C.
• Egyptian improved upon the process & Roman
started for the commercial purpose.
• The Normans carried the process to England
when they conquered it
• The term beer covers drink like ale, lager, stout
etc. The addition of hops started in the middle
of 16th century.
• The beer gets it name from Anglo Saxon word
called “BEER” which means barley.

4. Cont…Cont…
• In England the beer drinking house (Pub)
originated. These house were represented
by sign boards of King Head or Red
Rooster .
• Interesting fact is that generally beer
making countries does not produces
quality wine and vice-verse.

5. Ingredient of BeerIngredient of Beer
• Barley
• Hops
• Yeast
• Water
• Sugar

6. BarleyBarley
• Mainly the barley (Botanical name- Hordium
Vulgare) is used but can be produced from
wheat, rice combination of grains.
• The small amount of grain added along with the
barley is termed as “ADJUNCTS”.
• Adjunct can be added up to 35% but higher the
adjunct, lower cost, body and flavour
• German beer are made from 100% barley and
production process is governed by law enacted
in year 1909 called REINHEITSGEBOT MEANS
PURITY COMMAND.

7. BarleyBarley

8. ReasonsReasons
• Cheaply available.
• Not used as staple diet.
• Low in protein content, excess might
cause cloudiness.
• It has protective sheath, which protect
grain from contamination.
• It has two enzymes CYSTASE – convert
the insoluble starch to soluble starch,
DIASTASE- convert the soluble starch to
sugar

9. HopsHops
• These are cone or flower, obtained from
perennial plant called Hop vine, 20 meter in
height, last for around 20 years.
• Botanical name is “HUMULUS LUPULUS”
derived from Roman word Lupus Sallctarius
which means that “ sheep among wolf”.
• Cone or flowers of female species is uses for
beer making because it contain a yellow thick
substance called “LUPULIN” which contain
alpha acid called “HUMULONES” which
contributes to flavour, antiseptic, and
preservative.

10. Cont..Cont..
• Cone is called STROBLLE & petals are
called BRACTS. Cones are light green in
colour having 60-80 % moisture content.
• They are dehydrated in chamber called
OAST HOUSE.
• Best hops are Bavarian hops comes from
Germany and Czecslovakia.
• In India they are produced in H.P.

16. YeastYeast
• Microorganism cause the
fermentation, only seen
when massed together.
• Discovered by Anton Van
Loeuwenhoeck in 1685
• In 1857 Louise Pasteur
explained the function of
yeast in detail.

17. Yeast Powder & CellsYeast Powder & Cells

18. TypesTypes
• Saccharomyces Cerevaciae – Top fermenting yeast
work at 15 –19 0C & settle at top of wort after doing the
fermentation. Hence top-fermenting beer is drunk at 15-
19 0C.
• Saccharomyces Carlsbergeneces – Bottom fermenting,
settle in bottom of wort after fermntation , work at 2-6 0C
hence these beers are taken at 4-5 0C.
• Emil Hansen developed this yeast in 1883 by isolating
the first single cell of yeast in Carlberg brewery of
Denmark

19. WaterWater
• The body of beer consist of 90% of water. The quality
and mineral content affect the character of brew.
• Liquor is term given for water by brewers.
• Water contains six main salts namely bicarbonate,
sodium, chloride, calcium, magnesium and sulphate.
• High level of carbonate will produce acidic mash,
which will reduce the extraction of sugar from malts
• Too much sulphar will give bitterness in brew.
• Magnesium is a essential ingredients for yeast.

20. SugarSugar
• To speed up the fermentation.
• To reduce the bitterness.
• To give colour in the form of caramel.
• To cause secondary fermentation.

21. UsesUses
• Steeping the Grain – to increase the
moisture content up to 40% for
germination. Stored grain has only 10%
of moisture.
• Flavour – Water of place has different
mineral content, which impart distinctive
flavour.
• Provide bulk & body

23. STEEPINGSTEEPING
• The grains are soaked in huge tank of
water (six tonnes of barley and 6800 litres
of water) at 10 0C for 2 to 3 day.
• Some producer change water in between
to provide dry resting period & grain gets
the air also.

24. MALTINGMALTING
• Grains are taken to malt room, which is very
hard, grains are spread to depth of 15 – 30 c.m
to allow grain breath while sprouting.
• Grains are constantly stirred for uniform
breathing & to prevent sprout getting entwined.
• This process goes on for 6 – 15 days at 12 – 21
0C.

25. Malting RoomMalting Room

26. GERMINATIONGERMINATION
• During this process the insoluble starch gets
converted to maltose & dextrin & rootlets, known
as “ malts culms” appears.
• CYSTASE – convert the insoluble starch to
soluble starch,
• DIASTASE- convert the soluble starch to sugar.
• Grain is referred as Green malt.

27. Germinated BarleyGerminated Barley

28. KILNINGKILNING
• In this process the grains are spread on a
perforated, tilted floor with a furnace underneath.
Grains are dried & temp. maintained is 49 0C.
The extant to which grain should heated is
decided by the type of beer produced.
Types of Malts
• Pale malt- for light ale 65 0C
• Crystal malt- for pale ale 85 0C
• Chocolate malt- for dark beer 225 0C

29. Malted BarleyMalted Barley

32. Cont..Cont..
• SIEVING- It is done to remove malts
culms which sold as cattle feed.
• GRINDING- The grains are roughly
broken which are known as GRIST
through roller mill.

33. EXTARCTION OF SUGAREXTARCTION OF SUGAR
INFUSION- Huge tank called “MASH TUN”.
• Grist Added with Water
• The mixture is heated up to 63 0C for 2 hrs.
• The result in the formation of hot sweet liquid
called “ WORT’.
• Wort is filtered through finely slotted plate

34. MashtunMashtun

35. Cont..Cont..
DECOCTION- Tanks are called LATEUR TUN”.
• The grist is heated up to 70C.
• Some amount of wash is taken out & cooled
then added back to tank.
• This is carried out for 4 to 5 times & takes out 4
to 5 hrs.

36. BREW KETTLEBREW KETTLE
• From the under back the wort is pumped into a
vessel called “BREW KETTLE” which is
pressurized.
• In this vessel hops (191-907 gms/100litre,
depending upon the type of beer)& sugar is
added.
• The mixture is boiled for 2 hrs. This will sterilize
mixture.

37. Brew KettleBrew Kettle

38. Removal of HopsRemoval of Hops
• HOP BACK- The wort along with hops is
transferred to vessel called hop back, which is
having slotted plates forming a filter bed. The
content is allowed to stand for 40 min. to allow
hops to make a filter bed.
• HOP EXTRACTOR- This is machine, which
rotates, due to centrifugal force the hops are
thrown to sides of wall of inside tank. Then
hops are taken out.

39. FermentationFermentation
• Fermentation is process which convert the
sugar into alcohol & CO2.
• CO2 is stored in a different tank.
• This process takes 7 – 14 days.
• During the fermentation a thick layer of
yeast is formed which protect the beer.

40. Fermentation TankFermentation Tank

41. Lagering/ MaturationLagering/ Maturation
• Lagering takes place in stainless tank at 0
degree centigrade
• Beer is matured for few weeks to months
• Lagering matures beer & mallow its
flavour.

42. Cont..Cont..
• FINNING- It the process of clarification in
which protein like egg shell, ox blood, gall
bladder of sturgeon fish (Isinglass) is
added.
• Carbonation- Addition of Carbon di oxide
• Bottling/ Canning

43. PASTEURIZATIONPASTEURIZATION
• In this process the beer is heated up to
60-66 C for less than 20 min, which kill the
bacteria, & remaining yeast which may
allow further fermentation.

44. DRAUGHT (DRAFT)/ KEG BEER-DRAUGHT (DRAFT)/ KEG BEER-
• These beers are generally not pasteurized
• Many people thinks that pasteurization
kills authentic taste of beer.
• Stored at 2 to 3c away from the food store
area.
• Carbon di oxide tank should be stored into
different area and constant pressure
should be maintained.

• Canned beer- 1 year
• Draught beer – 48 hrs after being tapped.

49. Few termsFew terms
• DRY HOPING- From the racking back the
beer runs into wooden casks in which
small amount of hops already been
added. which gives beers delicate aroma,
flavour & assist in conditioning.
• PRIMINGS (sugar solution) are added to
take away extra dryness, bitterness &
promote secondary fermentation, which
gives sparkle to beer.
