Cervisia is a fancy word that grown-ups use to talk about beer. Beer is a drink that some grown-ups like to have on special occasions or when they are hanging out with their friends.
Cervisia actually comes from a really, really old language that not many people speak anymore. It means "beer" in that language. But even if you don't speak that language, you can still enjoy beer!
Beer is made from a few simple ingredients: water, grains, hops, and yeast. Yeast is a tiny little thing that helps turn the other ingredients into beer.
First, the grains are soaked in water to make a thick, soupy mixture called "wort." The hops are then added to this mixture to give the beer its special flavor. The wort and hops are boiled together for a while to help kill any germs that might make people sick.
After the wort has been boiled and cooled down, yeast is added. The yeast is like a little magic fairy that helps turn the sugary wort into bubbly beer.
The brewers then put the mixture into big containers called "fermenters" and let the yeast do its thing for a few weeks. During this time, the yeast eats all the sugar in the mixture and turns it into alcohol and carbon dioxide. This is what makes beer bubbly and gives it its special kick.
Once the fermenting is done, the beer is put into bottles or cans and sent out to stores for people to enjoy.
So in short, cervisia is just a fancy word for beer, which is made from some simple ingredients like grains, hops, water, and yeast. It takes a little bit of time and magic to turn these ingredients into the bubbly, delicious drink that many grown-ups love to enjoy.
