德国啤酒工艺介绍PPT
1. Introduction
Beer is one of the most popular alcoholic beverages in the world. Among them, German beer is well-known for its high quality and unique flavor. German beer has a long history and the brewing process is strictly regulated by the German beer purity law called Reinheitsgebot. The law is a set of regulations that restricts brewers to use only four ingredients when making beer. This law ensures the quality of German beer and makes it different from other beers around the world.
2. German beer brewing process
The German beer brewing process involves four main steps: milling, mashing, boiling, and fermentation. These steps are carefully followed to produce high-quality beer.
2.1 Milling
Milling is the first step in the German beer brewing process. The malted barley is crushed into smaller particles, also known as grist. The grist is then mixed with hot water in a process called mashing. The mixture is stirred and heated to different temperatures to activate the enzymes in the malt and extract the sugars.
2.2 Boiling
After mashing, the mixture is boiled in large kettles for several hours. This step serves to sterilize the mixture, dissolve the hops, and extract the flavors and aromas from the hops. Hops are added in different stages during the boiling process to ensure a balanced taste and aroma.
2.3 Fermentation
After boiling, the mixture, also called wort, is cooled and transferred to a fermentation tank. Yeast is added, which converts the sugars in the wort into alcohol and carbon dioxide. This process is called fermentation and takes several days or weeks. After fermentation is completed, the beer is transferred to a storage tank and kept at a low temperature for several weeks to mature.
3. Types of German beer
There are many different types of German beer, which are classified according to their brewing process, ingredients, and region. The most common types of German beer are:
