Discover the Most Common Inquiries on the Art of Brewing Beer

There may be several issues during the brewing process, whether they are major or minor, they will have an irreversible impact on your beer. However, both major and minor problems can be fixed to improve the quality of the beer. Here, you can learn how to enhance the quality of your beer through simple preventive measures.

Improper Cleaning

The first step in brewing delicious beer is to clean the equipment. Brewing is a complex process. Keeping the brewery equipment clean is not only important for maintaining orderliness but also for protecting the quality and flavor of the beer.

Important note: Please understand the crucial difference between cleaning and disinfection. Properly cleaning the brewery equipment helps remove dirt, dust, scum, as well as fat, protein, and other viscous substances that may spoil the flavor of the beer. Disinfection alone will not address these issues but it will eliminate unwanted bacteria that cannot be removed through cleaning alone.

Improper Disinfection

Inadequate sanitization of brewery equipment may result in beer with an unusual taste or fermentation issues. These problems are caused by harmful microorganisms present in the brewery equipment. Anything that comes into contact with the beer during the brewing process should be thoroughly disinfected. A professional CIP (Clean In Place) system can help you resolve such problems and set you on the path to craft beer success.

Use of Poor Quality Water

The tap water from your local area may taste great when consumed directly, but it can adversely affect your beer when used in brewing. Unfiltered chlorinated water can give your beer a metallic or plastic taste. The pH value and ion distribution of water vary in different regions, which can alter the final specific gravity, pH value, and flavor of the beer.

Around the world, many beer styles are influenced by the type of water available in their respective areas. For example, Bohemia, the birthplace of Pilsner beer, has soft water with minimal mineral content.

Your local tap water may lack the necessary minerals or pH balance required for the recipe you are using. You can use a water treatment device to adjust the local water quality and ensure the desired flavor in your beer. Additionally, you can fine-tune your recipe to achieve a balanced mineral content in the beer.

Slow or No Fermentation

Homebrewers often encounter the issue of beer not fermenting or fermenting slowly. When you transfer the wort to the fermentation tank with yeast, it may take 6-8 hours to observe signs of fermentation initiation. If there are no signs of fermentation, do not panic as it is normal. However, if there is no response after 72 hours, you should be concerned as it indicates a problem.

Check for signs of fermentation initiation:

(1) Check if the beer has started fermenting. Can you observe foam or a ring of brown scum around the fermenter’s manhole door? If yes, it means the beer is fermenting or has commenced fermentation.

(2) Use a hydrometer to measure the specific gravity of the beer. If the final specific gravity is one-third or one-fourth of the original specific gravity, fermentation has begun. For instance, if a 1.045 beer ferments to 1.015-1.012 or lower.

Reasons for slow or no fermentation:

(1) Insufficient yeast quantity. Insufficient yeast can result in slow fermentation. Simply adding more yeast to the fermenter can solve this issue.

(2) The wort is too hot. Each yeast strain has an appropriate temperature range. When the temperature is too high, yeast can become inactive or even die. The wort needs to be cooled before transferring it to the fermenter.

(3) The wort is too cold. As mentioned earlier, each yeast strain has an optimal temperature range. If the temperature is too low, yeast activity can slow down, leading to a sluggish fermentation.

(4) Although fermentation is progressing well, the fermenter may not be properly sealed, making it difficult to observe the start of fermentation.

(5) The fermenter has not been adequately rinsed after disinfection. Residual disinfectant can also kill the yeast. After disinfection, make sure to thoroughly rinse the inside of the fermenter to remove any disinfectant residue.
