5 basic components of an effective brewery
Today's beer industry is more competitive than many individuals imagine. Increasing competition, ever-changing consumer demands, and streamlined employees are driving many craft breweries to continuously innovate. Craft breweries need to bring delicious craft beer to the marketplace and provide consistent, high-quality beer products. Craft breweries can implement quality control plans that cover all basic knowledge through training, targeted investment, and time-tested technology. A brewery that consistently produces high-quality beer has 5 basic elements.
1. Good Manufacturing Practice (GMP)
GMP is a mix of best practices in risk management, training, traceability, and facility maintenance. Although the particular requirements of GMP will be different from brewery to brewery, these practices are the foundation for producing high-quality beer and making a safe and clean working space.
A typical brewery GMP must cover the steps required to generally meet all government regulations, such as for example food handling and equipment safety practices. The GMP also needs to include appropriate health and hygiene requirements, and the cleaning and maintenance of the brewery team and brewery equipment and tools (such whilst the CIP cleaning process of each brewery equipment). Additionally, GMP also needs to cover the employment and storage of chemicals, product date coding, and appropriate pest control.
Even a tiny brewery could have multiple team members performing similar procedures. The brewery should let everyone follow exactly the same correct steps to operate the brewery equipment to brew beer. Additionally, continuous internal audits are expected to guarantee the rigor of these procedures. This is a very important thing because it'll promote the consistency of the beer.
GMP will come into play even ahead of 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 utilize fabrics in wash areas where cleanliness and bacteria are considered.
2. Yeast cell count and viability test
Yeast is generally the sole living organism in beer and must be used and monitored carefully. When the quantity of yeast is insufficient, the fermentation process might be slowed up as well as unable to complete the fermentation. Additionally, it may also cause diacetyl to appear in the finished beer, leaving a peculiar smell just like butterscotch or buttered popcorn. Too fast fermentation will waste plenty of precious yeast and cause other problems.
Compressed yeast as a result of low cell counts or improper storage of yeast could cause undesirable characteristics in beer, such as for example beer with a natural apple or rotten egg flavor. To stop the yeast from being stressed, every brewery should conduct a yeast cell count and vitality test.
Testing yeast regularly requires the usage of widely available laboratory equipment, including microscopes and blood cell counters. You will find complete cell counting programs on the internet sites of several yeast suppliers and other industry resources. Many brewers consider themselves "yeast farmers" and are committed to maintaining the healthiness of the main biological factor in fermentation, and the main element factor in beer flavor and consistency.
3. Simple microbial detection
Brewer's yeast is an important biological component, but other microorganisms are often undesirable because they could have an immeasurable effect on the last beer. Bacteria (such as Lactobacillus and Pediococcus) and wild yeast (such as Brettanomyces) can very quickly contaminate the brewing environment. These equipment found on people, raw materials, air, or improperly cleaned equipment could cause beer deterioration, peculiar smell, unnecessary turbidity, and excessive carbonation. Oftentimes, these effects are only discovered after the merchandise is packaged, distributed, or sold to customers, which will be not conducive to the reputation of the brewery.
Those breweries that strictly adhere to GMP can provide good brewery hygiene and prevent beer deterioration caused by harmful microorganisms. However, the current presence of harmful microorganisms can only be determined through proper testing. It is recommended to utilize an HLP tube (Hsu's Lactobacillus-Pediococcus) to detect those beer spoilage bacteria in the finished beer. The brewer may use an external laboratory for testing or send samples to a brewery effective at testing for testing.
They are not very expensive or time-consuming practices, especially when contemplating the potential lack of revenue because of the reputational risks caused by damaged beer or product recalls. If at all possible, it is best to conduct microbiological testing throughout the brewing process, that has helped prevent potential problems. For a lot of large breweries, this can be exactly like the "wort stability test", which is a very low-tech technology.
4. Prevent oxidation
People need oxygen for life, but beer does not. Oxidized beer will produce a report or cardboard taste and will mask the aroma and flavor expected by the brewer. A couple of parts per billion (ppb) of dissolved oxygen (DO) in the finished beer will shorten the shelf life of the beer to only a few weeks. Measuring DO is vital, and it must be measured after filling the bright tank. Because the longer you wait before measuring, the lower the resin will be. The oxidation of beer can occur in lots of ways, but the most typical ones are improper cleaning of the bright tank, use of oxygen-enriched water, improper equipment operation and maintenance, or improper packaging.
Breweries that always follow standard maintenance and packaging usually avoid oxidizing beer, but there are some specific practices to bear in mind:
Cleaning and maintenance. Improperly cleaned and maintained pumps, valves, and gaskets could cause air to enter the beer equipment or packaged beer.
Packed properly. Make certain that the beer may be filled and covered normally to prevent 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 like 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. Once the measured values run above target levels, steps such as for example adjusting fill levels or seamer settings can be studied to prevent oxidized beer.
The brewery needs to utilize equipment that measures DO to gauge the upstream and downstream of potential oxygen entry points, which brings huge benefits to troubleshooting. Seals, pumps, and other tools help breweries detect potential risks in beer and take measures to eradicate them.
5. Beer sensory analysis
In a whole brewery, beer won't be packaged without tasting. This is because a strict sensory analysis plan is going to be developed in a whole brewery. This is the main beer quality check. Does the beer taste good? Do you wish to drink it again? Are your web visitors content with the beer flavor?
Sensory analysis procedures may be simple and fun. The brewery needs to have selected and trained staff (may not be brewers) members to choose odors and understand the right style characteristics of the brewery. These members are called sensory analysis teams. They will taste the beer in the bright tank your day ahead of the planned packaging. The beer is going to be packaged only following the beer flavor is qualified.
Additionally, the packaging and quality team also needs to select a few of the packaged beer to store for later tasting. This assists the team have a great comprehension of the shelf life of every style and provide insights into how flavor characteristics change over time. You can even find that some reliable tasters spend almost no amount of time in the production workshop, but they've a higher amount of recognition of certain peculiar smells compared to most experienced winemakers.
Using targeted, data-driven quality assurance methods, breweries can save plenty of time and money and will avoid potential future batch problems. Leadership team members must strictly adhere to each of the 5 basic elements and make improvements to the basic elements. We believe that your brewery may be successful!
