Knowing beer production

  1. 1. Knowing beer production England is a beer brewing country. Is the second beer producer of the world with 45 millions of beer hectoliters per year and the sixth world beer consumer. But one thing is loving and drinking beer and other knowing how it is made. Alex Brandon-Davies, brewer from The Leeds Brewery Company, where traditional beer is still produced, explains the whole process.
  2. 2. The blend is transferred to the third tank; the heat exchanger, where it will be cooled first thing to be known is the ingredients, in the case of Leeds Brewery they use: 95 % of tap water, British malted barley, hops and Yorkshire to or lager yeast.

  3. 3. A non-alcoholic and non-bitter liquid is obtained from this first step. The mash goes to the kettle. Here is boiled with the hops. ‘This is the most important and interesting part of the process because the flavour and bitterness of the beer are determined at this point’ says the 28-year-old brewer.

The cooling before fermentation is the key to make possible the yeast growing, because it can’t grow in high temperatures. On the way to the fermentation room the wort is oxygenated.

  6. 6. ‘We check beer’s density everyday with an hydrometer. By measuring it we find out how alcoholic and how strong it is’ says the Leeds brewer. The yeast eats the sugars in the wort producing alcohol which is less dense than water. That is the goal, reducing density to achieve a thin fermented wort.
  7. 7. ‘The yeast is removed from the tank and put in the fridge for the next brew. It is reusable, we could say that it can be used infinite times’ explains Alex. The wort is conducted to a tank, covered with a cooling jacket, which will stop the fermentation and cool down the beer to 12º.
  8. 8. ‘After fermentation, the beer is moved to the conditioning tank where it will mature during 48 hours. A second fermentation will take place in the racking casks’ says the brewer. During cask filling isinglass (swim bladder of sturgeon) is added to help the sedimentation of yeast in the cask.
  9. 9. ‘To improve the beer’s clarity we add finings. This way the remaining yeast and any solid left in the beer will be removed and we will obtain the final product: clear, traditional and quality Leeds’ beer’: explains the 28-year-old brewer, who has been producing beer for more than 5 years.
