  1. Brewing in Scotland: A brief history of beer and its production Dallas Iain; Kelly Will

  2. Ingredients • Water • Malted Grains • Hops • Yeast

  3. Grains are allowed to germinate before being dried Used for enzyme production Malted Barley: Malted Grains

  4. Female flower cones of Humulus Lupulus plant Flavouring and stability agent Cultivated since 736 a.d Hops

  5. The yeast species Saccharomyces cereviciaehas been used in fermenting alcoholic beverages for thousands of years Converting sugars to alcohol Yeast

  6. Beer Production is split into 7 Sections: Mashing Lautering Boiling Fermenting Conditioning Filtering Packaging The Process

  7. Water + Malted Grains Enzymes change Starch to sugars such as Maltose Different Temperature levels activate different enzymes Starch (C6H12O6)n => Maltose (C12H22O11) The process : Mashing

  8. Separation of extracts won during mashing from spent grain to create “ Wort” Mashout Recirculation Sparging Equipment used : Lauter Tun Mash Filter The Process: Lautering

  9. Ensures Sterility Hops added at this stage Vapours of the boil affect flavours, e.g Dimethyl Sulphide Dimethyl Sulphide: (CH3)2S The Process: Boiling

  10. Yeast added to the compound Sugars produced during mashing converted to Alcohol and Carbon Dioxide Maltose(C12H22O11) => Ethanol (CH3CH2OH)+ Carbon Dioxide (CO2) The Process: Fermenting

  11. Yeast begins settling at the bottom of the tank Beer is cooled to O degrees Celsius Phenolic compounds become insoluble in the beer Sulphur also reduced by extended cooling The Process: Conditioning

  12. Stabilises the beers flavour by removing particulates Divided into Rough, Fine and Sterile The Process: Filtering

  13. Bottle or cask? Bottle Fermentation Cask Conditioning The Process: Packaging
