Why do you cap a beer tap?

Answered by Matthew Yawn

As a seasoned sommelier and brewer, I can attest to the importance of capping draft faucets when they are not in use. This simple yet effective practice serves multiple purposes that contribute to maintaining the quality and cleanliness of the beer being served.

1. Prevention of Fruit Flies: One of the primary reasons for capping beer taps is to keep pesky fruit flies away from your bar area. These tiny insects are attracted to the sweet aroma of beer and can quickly become a nuisance for both customers and staff. By covering the faucet with a cap, you create a barrier that prevents fruit flies from accessing the beer, reducing the risk of contamination and ensuring a pleasant drinking experience for patrons.

2. Avoidance of Sediment and Build-up: Another crucial benefit of using a cap on draft beer faucets is the prevention of sediment and yeast accumulation inside the spout. When beer is poured, it can sometimes leave behind small traces of sediment or yeast, which can settle in the faucet over time. This build-up can affect the taste and quality of subsequent pours, leading to an undesirable drinking experience for customers. By placing a cap with a built-in brush in the spout, you effectively eliminate the possibility of sediment and yeast accumulating, maintaining the integrity of the beer being served.

3. Hygiene and Cleanliness: Capping beer taps also contributes to the overall hygiene and cleanliness of the bar area. By covering the faucet when not in use, you protect it from dust, dirt, and other contaminants that can compromise the quality and taste of the beer. Additionally, using a cap with a brush not only prevents build-up but also helps to remove any residual particles that may have settled in the spout. This practice ensures that each pour is clean and free from any unwanted impurities, providing a positive drinking experience for customers.

4. Cost Efficiency: Capping beer taps can also have financial benefits for bar owners or operators. By preventing fruit flies and sediment build-up, you reduce the chances of beer spoilage or wastage. When beer is contaminated or compromised, it may need to be discarded, resulting in monetary losses. Additionally, regular cleaning and maintenance of faucets can be time-consuming and costly. By utilizing caps with built-in brushes, you minimize the need for frequent deep cleaning, saving both time and money.

Capping draft beer faucets when not in use is a simple yet effective practice that offers numerous benefits. By preventing fruit flies, sediment build-up, and contamination, you maintain the quality, taste, and cleanliness of the beer being served. This practice not only enhances the overall drinking experience for customers but also contributes to cost efficiency and hygiene in the bar environment.
