In a perfect world, beer would taste the same at package release as it does at the end of its shelf life. In reality, beer begins to undergo flavor modifications as soon as it leaves the brewery. Consequently, flavor instability is now one of the brewing industry's most critical quality problems. With the introduction of the new LP Series, Maselli has developed LP20 – Portable and Laboratory O2 Analyzer – the perfect tool for craft breweries that need to perform accurate Dissolved Oxygen analysis both in the processing plant and in the QC Laboratory of their facility.
Why Oxygen?
Brewing high-quality beer requires meticulous attention to detail, and maintaining its quality is paramount. One of the biggest challenges brewers face is preventing oxidation, which can irreversibly damage the final product. That’s why monitoring dissolved oxygen levels throughout the brewing process is so important. By closely monitoring oxygen levels, brewers can catch any issues early and ultimately guarantee customers a top-quality final product.
What happens if you don’t monitor DO levels
Monitoring DO levels is essential to maintaining the integrity and success of the brewing process. Apart from oxidation, non-monitoring of DO levels can lead to reduced product shelf life and cause inconsistency in quality. Economic losses from unsellable, spoiled batches and high oxygen levels can also encourage microbial contamination, further compromising your beer's safety and quality.
Maselli solution
As oxygen needs to be avoided all the way through production, it is important to measure dissolved oxygen content throughout the process. The scheme shows the typical points where O2 may enter the process.Portable solution for immediate check at any stage
At each point where Oxygen can enter the process, Maselli can measure DO levels with LP20 | Portable O2 Analyzer. Using the Maselli LP20-Oxygen, you can measure at-line (directly connecting the instrument to piping or tanks) the dissolved oxygen concentration.
LP20 allows you to have a clear view of the whole process and to take corrective actions where needed, avoiding waste of time, resources, and consequently money.
What do we mean by “Portable & Laboratory”? - With its portability features and its own rechargeable batteries, the LP20 can be taken anywhere and used right from the tanks at your production line to monitor the beer in different steps of the brewing process. With its easy connection to the Maselli Automatic Sampler SL01, the LP20 can be used in the laboratory as well. The sampler can handle any type of container, including cans, bottles, and PET.
How does that work? The equipment determines the DO content based on optical technology (fluorescence quenching) to ensure fast and incredibly accurate analysis.
Not only beer… the LP20 is suitable not only for the beer industry but also for measuring sparkling wine, seltzers, or any other carbonated beverage.
Words to the experts: At Birrificio della Granda in Saluzzo, Italy, stability of flavor and overall beer quality is a top priority. Back in 2020, the brewery purchased an LP20 to increase its control over its process. The experience of Birrificio della Granda with LP20 equipment has proved to be very successful. The brewery can now guarantee its consumers a high-quality product with the right CO2 values and oxygen levels to ensure their beer’s shelf-life and original taste over time.
