Good Manufacturing Practice (GMP)
A typical brewery GMP needs to cover the steps required to meet all government regulations, such as food handling and equipment safety practices. The GMP should also include appropriate health and hygiene requirements, and the cleaning and maintenance of the brewery team and brewery equipment and tools (such as the CIP cleaning procedure for each brewery equipment). In addition, GMP should also cover the use and storage of chemicals, product date coding, and appropriate pest control.
Even a small brewery will have multiple team members performing similar procedures. The brewery should let everyone follow the same correct steps to operate the brewery equipment to brew beer. In addition, continuous internal audits are required to ensure the rigor of these procedures. This is a very important thing because it will promote the consistency of the beer.
GMP can come into play even before the brewery is opened, and everyone needs to follow proper design and construction protocols. For example, avoid using porous or fibrous materials (exposed plasterboard, wood, etc.). Breweries need to use fabrics in wash areas where cleanliness and bacteria are considered.
Yeast cell count and viability test
Compressed yeast due to low cell counts or improper storage of yeast can cause undesirable characteristics in beer, such as beer with a green apple or rotten egg flavor. To prevent the yeast from being stressed, every brewery should conduct a yeast cell count and vitality test.
Testing yeast regularly requires the use of widely available laboratory equipment, including microscopes and blood cell counters. You can find complete cell counting programs on the websites of many yeast suppliers and other industry resources. Many brewers consider themselves “yeast farmers” and are committed to maintaining the health of the most important biological factor in fermentation, and the key factor in beer flavor and consistency.
Simple microbial detection
Those breweries that strictly abide by GMP can provide good brewery hygiene and prevent beer deterioration caused by harmful microorganisms. However, the presence of harmful microorganisms can only be determined through proper testing. It is recommended to use an HLP tube (Hsu’s Lactobacillus-Pediococcus) to detect those beer spoilage bacteria in the finished beer. The brewer can use an external laboratory for testing or send samples to a brewery capable of testing for testing.
These are not very expensive or time-consuming practices, especially when considering the potential loss of revenue due to the reputational risks caused by damaged beer or product recalls. If possible, it is best to conduct microbiological testing during the brewing process, which has helped prevent potential problems. For many large breweries, this may be the same as the “wort stability test”, which is a very low-tech technology.
Prevent oxidation
Breweries that always follow standard maintenance and packaging usually avoid oxidizing beer, but there are some specific practices to keep in mind:
- Cleaning and maintenance. Improperly cleaned and maintained pumps, valves, and gaskets can cause air to enter the beer equipment or packaged beer.
- Packed properly. Ensure that the beer can be filled and covered normally to avoid excessive air entering the beer during packaging. However, keeping proper air and yeast in the packaging is conducive to the purity of beer flavor.
- Measure DO and TPO. Many brewers use tools such as the Anton Paar CBoxQC or the Haffman’s Portable Optical CO2/O2/TPO Meter c-DGM to measure DO and total packaged oxygen (TPO) during each run. When the measured values run above target levels, steps such as adjusting fill levels or seamer settings can be taken to avoid oxidized beer.
Beer sensory analysis
Sensory analysis procedures can be simple and fun. The brewery needs to have selected and trained staff (may not be brewers) members to pick out odors and understand the appropriate style characteristics of the brewery. These members are called sensory analysis teams. They will taste the beer in the bright tank the day before the planned packaging. The beer will be packaged only after the beer flavor is qualified.
In addition, the packaging and quality team should also select some of the packaged beer to store for later tasting. This can help the team have a good understanding of the shelf life of each style and provide insights into how flavor characteristics change over time. You can even find that some reliable tasters spend very little time in the production workshop, but they have a higher degree of recognition of certain peculiar smells than the most experienced winemakers.
