How often should a draft system be cleaned to prevent off flavors in beer?

1. Every week

2. Every 14 days

3. Once a month

4. Every 6 weeks

The correct answer is: Every 14 days

The recommended frequency for cleaning a draft system is every 14 days. This routine maintenance is vital for ensuring the quality and taste of the beer served. Over time, beer lines can accumulate yeast, bacteria, and other residues that can lead to off flavors and negatively impact the beer's overall quality. Cleaning every two weeks helps to minimize the risk of these contaminants building up, promoting a cleaner and fresher beer experience for consumers. Other suggested frequencies, while still maintaining cleanliness, may not be sufficient to address potential buildup adequately. Cleaning once a month or every 6 weeks, for example, could allow for greater accumulation of undesirable elements, which could eventually compromise the flavor and character of the beer served. Regular cleaning every two weeks strikes a balance between effective maintenance and operational efficiency for most establishments serving draft beer.
