  • BeerBeer
  • DefinitionDefinition • Beer is defined as a fermented, alcoholic beverage made from barley, wheat, rice etc. & flavoured with hops.
  • 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.
  • 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.
  • Ingredient of BeerIngredient of Beer • Barley • Hops • Yeast • Water • Sugar
  • 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.
  • BarleyBarley
  • 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
  • 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.
  • 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.

  • Reasons- Uses of hopsReasons- Uses of hops • Flavour • Preservative • Antiseptic • Aroma • Clarifying agent
  • Brand names of HopsBrand names of Hops • Brewer gold • Northern brewers • Fuggles • Bavarian hops • Saaz • Secret • Perle • Progress • Tradition • Cascade
  • 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.
  • Yeast Powder & CellsYeast Powder & Cells
  • 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
  • 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.
  • SugarSugar • To speed up the fermentation. • To reduce the bitterness. • To give colour in the form of caramel. • To cause secondary fermentation.
  • 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
  • Production ProcessProduction Process • STEEPING • MALTING • GERMINATION • KILNING • SIEVING • GRINDING • EXTRACTION OF SUGAR INFUSION DECOCTION • BREW KETTLE HOP BACK HOP EXTRACTION • FERMENTATION PARA FLOW • LAGERING • FINING • CARBONATION • BOTTLING • PASTEURIZATION
  • 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.
  • 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.
  • Malting RoomMalting Room
  • 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.
  • Germinated BarleyGerminated Barley
  • 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
  • Malted BarleyMalted Barley
  • 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.
  • 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
  • MashtunMashtun
  • 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.
  • 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.
  • Brew KettleBrew Kettle
  • 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.
  • 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.
  • Fermentation TankFermentation Tank
  • 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.
  • 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
  • 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.
  • 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.
  • Draught Beer ContainersDraught Beer Containers Container Gallons • Pin 4.5 • Firkin 9 • Keg 10 • Kilderkin 18 • Barrel 36 • Hogs head 54 Note- 1 gallons = 4.554 litre.
  • Keg / Draught BeerKeg / Draught Beer
  • StorageStorage • Lager beer should be stored in dark place at 4-5c & bottle should be kept in horizontal position. • Ale beer is stored at 10-12c
  • Life SpanLife Span • Bottle beer – 6 months • Canned beer- 1 year • Draught beer – 48 hrs after being tapped.
  • 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.
  • TYPE OF BEERTYPE OF BEER • Bottom Fermenting • Top Fermenting
  • Bottom Fermenting BeerBottom Fermenting Beer LAGER- The generic name for any bottom fermenting beer. • Lager came from German word “ LAGERN” (to store) & applied to bottom fermenting beer. • Lager was traditionally stored in cellars or caves for completion of fermentation. • They are bright gold to yellow in colour with a light to medium body & are well carbonated
  • PILSNERPILSNER • The golden colour lager from Czech republic, hops emphasis on palate, aged in wooden casks & alcoholic strength is 5%v/v. • Brands name- EB Special, Jever, Pilsner Urquell.

  • Dopple BockDopple Bock • Dopple bock is separate classification. The German dopple bock has minimum of 7.5% v/v alcoholic strength. • The strongest will go up to 13.2% v/v made by Eisbeck method & there name generally finished with ator like salvator, kulminator, maximator etc.
  • KulminatorKulminator • STRONG BEER- The strongest beer in world in KULMINNATOR (13.2% v/v from Germany). • Eis means ice indicating that beer is frozen during production resulting in freezing of water content of beer. • Frozen water is removed thus increasing beer alcoholic strength.
  • Light BeerLight Beer Low calorie beer from USA & Britain with 4%v/v. • Brands name- Miller,
  • Steam BeerSteam Beer • A highly carbonated beer, deep brown coloured with aromatic flavour of cloves, prange peel, peach & tangy bitter taste with dry finish. • The name steam originated from final “KRAUSENING” stage of fermentation in which partially fermented wort is added to speed up the fermentation which produce extra froth, termed as steam. • It has it origin in San Francisco & California during gold rush.
  • Top FermentingTop Fermenting • ALE- Originally produced in Britain with 4% v/v. Its has darker colour than lager beer with more hops, aroma with less of carbonation. Ale is usually bitter to taste with slight tanginess. In Britain it is referred as “Bitter”. • Brands name -Natural, Founder, Greenmantle.
  • Cream AleCream Ale • A sweetish, smooth golden ale from US. Beer which made by blending of little ale with larger amount of lager beer.

Beers made by this process have been successfully produced only in the valley of river Sienne, west of Brussels. • Brands name- Chapeau, Belle- Vue
  • IPA- India Pale AleIPA- India Pale Ale • This is strong heavily hopped beer brewed in Britain. The recipe was designed to with stand long sea voyages to distant part of British Empire like India
  • SakeSake • Sake is an ancient fermented beverage known to have been made since about the third century A.D in china. But it was not until about 600 years ago that sake, as we know it today was produced. • In ancient times, the making and serving was entrusted to brewer called “Toji” who incidentally has to be virgin. • Sake is produced in Japan, part of Chine other Asian countries & Hawaii, California. In Chine the similar rice beer is called “Samshu” & Korea “Suk”
  • ProductionProduction • Rice polished to perfection, for in making sake • Soaked in cold distilled water for 12- 18 hrs to moisture, steamed for 45 minute in “KOSHIKI” (Rice containing tub). • Cooled then spread in room called “KOJI” where mold “Aspergillus Oryzae”. • Fermaentation for 15 to 20days with “Saccharomyces Cerevisiae”. • Matured in stainless steel casks for 90-100 days then it pasteurized & bottled
  • ServiceService • The sake is traditionally served warm at 100- 110 fhrenheit. • At this temp. the heady bouquet (12-17% alcohol ) of sake is released. • To serve sake in Japanese traditionally, it is decant in ceramic pitcher called “TOKUURRI” then poured in small ceramic cup called “ SAKAZUKI”(one ounce)
