A: What is the relationship between wort concentration and alcohol concentration? Are they a mean? For this problem many people think that the degree of beer is the alcohol concentration of beer, it is not true. We often say that the degree of beer is the original wort concentration of beer, not alcohol.

Wort Concentration Meaning:

1, Low concentration of beer

Wort concentration of 6 ° - 8 °, alcohol content is the lowest, usually 2%, the most suitable in the summer as a cool drink, the disadvantage is poor stability, shorter storage time.

2, The concentration of beer

Wort concentration of 10 ° - 12 °, alcohol content of about 3.5%, 12 degrees for the general, is the main varieties of beer production in China.

3, High concentration of beer

The wort concentration is 14 ° to 20 ° and the alcohol content is close to 5%. Internationally recognized beer more than 12 degrees for the high-level beer, this beer brewing cycle is long, good stability, and resistant to storage and long-distance transport.

The meaning of alcohol concentration:

1, The degree of beer

The degree of beer and the degree of liquor represented by the meaning is different, the degree of liquor refers to its alcohol content, while the degree of beer refers to the beer production of raw material wort concentration. Beer contains alcohol from maltose conversion, marked with "12 °" of beer, the beer is a sugar content of 12 ° made of wort brewed.

2, The degree of beer alcohol

The alcoholic mass of the beer is calculated as the percentage by volume (M / V%), and the 12 degree marked on the mark refers to the original wort concentration, so the alcohol level should be about 4 °. Under normal circumstances, the majority of beer alcohol content between 2-5%, the common light beer is 3.3-3.8%; color beer is 4-5%; while the German beer alcohol concentration is relatively high, about 5- 9%, and bitter taste heavier. The higher the alcohol content of the beer, the better the quality.

To sum up, wort concentration and alcohol concentration are proportional to the relationship between the two. Such as the original wort less than 10 ° P, the degree of alcohol is generally not super but 5 degrees, are low beer. While the black beer is often up to 15 ° P to 20 ° P, then the degree of alcohol is often more than 5 degrees. Therefore, consumers do not confuse, wrong the original wort concentration as alcohol.
