Making Beer and Wine

Making Beer and WineMade by fermentationSugars from beerusually come frombarleyYeast converts sugar into EthanolSugar --> Ethanol + Carbon dioxideSugars from wine comefrom grape juiceEthanol is a depressant, itsslows down signals in thenerves and brainYeast are killed by theEthanol they produce asEthanol is poisonousDamage to the liver1) The Barley germinates for a few days. In this time,the starch grains are broken down into sugar by theenzymes. The grain is dried on a kiln (malting)2) Matled grain is mashed andwater is added providing asugary solution. A sieve is thenused to remove bits3)Hops are added to give a bitter flavour1) grapes are mashed and water addedAfter the initial steps above, Beerand Wine making is the same...Yeast is added and incubated, Yeast stopsmicroorganisms and ferments the sugar intoalcohol (yeast respires anaerobically)Beer and Wine is drawn off through a tapSometimeschemicals(clarifyingagents) removeparticles makingit clearerBeer is then pasteurisedto kill any yeast left andstop fermentation. (Wineisn't pasteurised, anyyeast left carry onfermenting the sugar) Thismakes wine taste better.Beer also takes betterwithout pasteurisationhowever it will spoil.Beer is cracked and wine bottled!*Rising concentration ofethanol in fermentationmixture kills the yeast, dueto anaerobic respiration,yeast dying slows downfermentation*Double click this nodeto edit the textClick and drag this buttonto create a new node
