What factors determine the taste of craft beer?
Good quality beer must have a pure, refreshing and mellow taste. If the beer tastes abnormal, consumer satisfaction will inevitably decrease. Therefore, it is necessary to understand the factors that affect the beer taste during the brewing process, and take measures to strictly control it to prevent the beer from producing odor.
1.The impact of brewery equipment on beer
If a worker wants to do his job well, he must first sharpen his tools. Having a set of beer brewing equipment with scientific and reasonable design and complete functions can not only reduce the saccharification brewing time, improve processing efficiency, save labor costs, but also ensure the taste stability of the finished beer.
In addition to brewing equipment that has a certain impact on finished beer, brewing raw materials, brewing recipes and brewing technology will all have an impact on beer.
2.The influence of malt on beer taste
Malt is the main raw material for brewing beer, and its quality directly affects the taste of beer. If the process conditions are not well controlled during the malting process, it will directly bring bad taste such as musty, sour, and bitter taste to the beer. Excessive malt dissolution will darken the beer color and thin taste; High steep-out moistures; Too low baking temperature, beer will appear fishy; Malt can not be eradicated Net, the beer taste will appear bitter.
The quality of malt has a greater impact on the flavor of beer, so try to choose a large malt processing factory with guaranteed quality.
3.The influence of brewing water on beer taste
The quality of beer brewing water directly affects the quality and taste of beer. Too much carbonate content or alkalescence can easily extract the bitterness of the bark. Even if the amount of bitter hops is reduced, the bitterness is difficult to eliminate. When the PH value of the brewing water is greater than 7, and the PH value of the produced wort is greater than 5.6, the brewed beer has a heavy bitterness and a rough taste. If the content of iron salt in the water is too high, the beer will have an iron smell; When using tap water, pay attention to the chloride ion content, too much will make the beer taste salty and have a bleach taste.
4.The influence of hops on beer taste
Hops give beer a special fragrance and bitterness. If hops are aged for too long, they will be oxidized, causing the beer to produce a rough and pungent bitterness. Be sure to keep it cold and sealed. In addition, adding too much hops and boiling for too long will cause unpleasant bitterness in the beer.
5.The influence of yeast on beer taste
Beer with pure taste should not have a yeasty taste, but if the fermentation and storage temperature is high, the fermentation is not vigorous, the amount of yeast added is large, and the yeast is aging, it can cause the yeast cells to autolyze and make the finished beer have a yeasty taste to varying degrees. Therefore, the dead yeast and protein condensate at the bottom should be discharged in time when the tank is full for 24 hours. After the diacetyl reduction reaches the process requirements, the temperature should be cooled in time.
6.The influence of brewing technology on beer taste
The control of saccharification temperature and time affects the ratio of sugar to dextrin in the wort. The content of dextrin is too low and the beer lacks mellowness. The husks of the malt are crushed too finely, the wort is cooked too long, the spent grains washed too much, the wort has low boiling strength, long boiling time, and high solidified nitrogen content, which will all cause the beer's bitter taste to be incorrect. The pH value of wort has a great relationship with the bitterness of the wort. The higher the pH value, the greater the bitterness and roughness. And the lower PH value,although the utilization rate of bitterness is lower,the bitterness is soft and palatable.
7.The influence of carbon dioxide on the taste of beer
Carbon dioxide imparts a thrill taste of beer, which is beneficial to prevent oxidation of the beer, lower the pH of beer, prevent contamination by bacteria, and make the beer taste softer and refreshing. Lack of CO2 can cause impure and boring taste. The amount of CO2 dissolved in beer is related to pressure and storage temperature. The higher the tank pressure and the lower the temperature, the more CO2 is dissolved, and vice versa.
8. The influence of process hygiene on beer taste
Because wort is a nutrient-rich medium, various microorganisms are easy to multiply and grow.If the hygiene control of each link is not good,it is easy to be infected with microorganisms, and different microorganisms produce different tastes. The brewing process must follow the established standard operating procedures and strictly control the details of the process to ensure the stability of the beer, so that the craft beer that consumers can drink every time can achieve fresh, pure, refreshing and rich taste.
9.Different recipes make different flavors of beer
Beer raw materials are composed of malt, yeast, hops and water. Different varieties of raw materials and matching ratios produce a variety of beer flavors.
To sum up, good beer = good beer brewing equipment + good raw materials + good formula + good process.DEGONG can provide the best brewing equipment.If you have interest,welcome to contact me freely.
