About the process
Brewing beer is not as difficult as everyone thinks. Yes, you may need some knowledge in chemistry, but it may be enough just to read and read some books about the process of brewing and just practice. And not to forget about creativity. When the brewer is creative, the beer will be good. You can find so much information nowadays about beers and how they are made, the only thing that you need is just time for it and some interest.
But with all this information, I realized that not everyone who drinks beer knows how beer is made. Yes, we all know about Reinheitsgebot or the German Beer Purity Law which says loud and clear that beer is made of water, hops and barley. They forgot about the yeast, but no worries, they did not consider it an ingredient in 1516.
