Elevating the Art of Craft Beer through Precision Measurement Techniques

The craft beer industry has witnessed a remarkable rise in popularity, with discerning consumers seeking distinctive flavor profiles and superior quality. Craft breweries must prioritize consistency and excellence throughout the brewing process to satisfy these discerning palates. Integrating advanced measurement solutions for critical parameters such as pH, dissolved oxygen, gaseous oxygen, and turbidity is paramount to attaining optimal outcomes and preserving the intended taste characteristics of craft beers.

The Role of pH in Crafting Exceptional Beers:

The acidity or alkalinity of the brewing environment, quantified by pH, exerts a profound influence on the activity of enzymes, the well-being of yeast, and the ultimate flavor profile of the beer. Precise pH monitoring is indispensable for maintaining batch-to-batch uniformity. Cutting-edge pH meters with features like automatic temperature compensation and calibration functionality empower brewers to track and fine-tune pH levels closely throughout the brewing cycle. By diligently regulating pH within the ideal range, brewers can ward off undesirable flavors, guarantee efficient fermentation, and create beers that exemplify their intended taste attributes.

Dissolved Oxygen: A Critical Factor in Beer Quality:

The dissolved oxygen concentration (DO) in beer is a pivotal consideration, as it can significantly impact flavor stability and longevity. Excessive DO levels can trigger oxidation reactions, imparting stale or cardboard-like off-flavors to the beer. Cutting-edge DO meters employing optical sensing technology deliver precise and dependable measurements, empowering brewers to monitor and regulate vigilantly DO concentrations across the brewing and packaging stages. By minimizing the beer's exposure to DO, craft breweries can safeguard the freshness and integrity of their products.

Mitigating the Impact of Gaseous Oxygen:

Beyond dissolved oxygen, gaseous oxygen in the brewing environment warrants meticulous attention. Gaseous oxygen can infiltrate the beer during transfer processes, bottling, or canning, potentially leading to oxidative deterioration and compromised flavor. Advanced gaseous oxygen analyzers equip brewers to identify and quantify oxygen levels in the headspace of packaged beer. By diligently monitoring and controlling gaseous oxygen, craft breweries can effectively prevent oxidation and preserve the intended flavor characteristics of their beers.

Ensuring Beer Clarity through Turbidity Control:

Its turbidity or clarity greatly influences the visual allure and overall perception of craft beer. High-precision turbidity meters offer reliable and consistent measurements, enabling brewers to closely monitor the clarity of their beers at different junctures in the brewing process. By expertly manipulating turbidity levels, craft breweries can guarantee a consistent visual presentation and cater to consumer expectations, whether the desired outcome is a crystal-clear or intentionally hazy beer.

In conclusion, adopting state-of-the-art measurement solutions for pH, dissolved oxygen, gaseous oxygen, and turbidity is crucial for craft breweries aiming to elevate the quality and consistency of their offerings. Precise and reliable measurements arm brewers with the insights needed to make well-informed decisions, streamline their processes, and consistently deliver exceptional craft beers to their patrons. By strategically investing in cutting-edge measurement technologies, craft breweries can optimize their operations, minimize product inconsistencies, and cement their reputation as producers of top-tier, flavor-forward beers that stand out in the fiercely competitive craft beer landscape.

Preserve CO₂ When Purging Beer Tanks With the Mettler Toledo InTap Portable Dissolved Oxygen Analyzer

A craft brewer uses CO₂ to purge oxygen from the headspace in bright beer tanks to reduce dissolved oxygen levels in final products. They used a time-based method to determine when to determine purge completion, but this is an imprecise method that can overuse expensive CO₂. METTLER TOLEDO provided the InTap portable oxygen analyzer to the craft brewer. InTap measures dissolved oxygen levels down to 2 ppb using a highly precise optical sensor, making it suitable for a wide range of brewery applications ranging from purging to monitoring filling lines.

This video discusses how a craft brewer reduced CO2 use with a convenient, portable oxygen meter.

It addresses critical issues concerning beer production, such as: 

• Complete tank purge determination.
• Why use a portable meter to measure dissolved oxygen? 
• How to Increase Your Product Quality Confidence

Brewers, Make Oxygen More Your Friend, and Less Your Enemy. Check Out the Mettler Toledo InTap™ Portable Optical DO analyzer

InTap™ DO Analyzer 

Brewers have a complicated relationship with oxygen. 

At times oxygen is your friend. It's needed for barley germination. It's needed to synthesize fatty acids and sterols in yeast. And it improves colloidal stability. 

Oxygen is also one of the the brewers worst enemies. It has a significant effect on color. It lowers the  rate of wort separation. It can cause undesirable flavors. And is causes haze and makes finished beer stale.

By the way, we're talking about the dissolved oxygen (DO) in solution here. Not the external oxygen the water, wort, or beer tank headspace.

Fortunately Mettler Toledo provides instrumentation to assist brewers in they management of oxygen. Their InTap™ DO analyzer with optical technology, is both a portable measurement tool and a convenient calibration instrument. It facilitates measurement and calibration procedures in both process and laboratory settings, and reduces the risk of operator error.

The InTap™ portable oDO analyzer is a portable measurement device for dissolved oxygen

measurement and for calibration and data logging of optical dissolved oxygen ISM® sensors

(InPro® 6970i) installed in the process. The InTap™ and the sensors communicate via Bluetooth.

Measurement point tracking in the InTap™ portable dissolved oxygen meter allows operators to easily connect stored measurement data to different locations in production, making it easy to maintain records point-by-point for traceability and documentation purposes.

Reliable optical dissolved oxygen (DO) sensor technology is also available in the InTap™ portable meter for spot check and reference measurements. With Blue- tooth communication, hassle-free calibration of in-line DO sensors is done quickly and easily.

Analytical Measurement Solutions for Optimization of Your Brewing Process

Stages of brewing and areas for process measurement.

The beer market is currently experiencing an intense globalization process, reflected in escalating competitive and cost pressures. In addition to this, there is growing diversification into new, innovative beverages that demand maximum production flexibility. The time to market is becoming ever shorter, and product quality has to be guaranteed at a consistently high level, accompanied by an increase in productivity.

In-line Measurements in the Brew House

Proper process control plays a vital role in determining the flavor, foam stability, and color of the finished beer. The relative measurement sensors are exposed to high temperatures, and solid particles and turbidity constituents, and must be capable of surviving multiple CIP cycles.

Turbidity Sensor

Measurements in the Fermentation and Storage Cellars

At standard fermentation temperatures, propagation of microorganisms is detrimental to the beer. In order to prevent this from occurring, hygienic plant design and use of materials resistant to CIP solutions are important criteria, as they are for in-line sensors.

DO and CO2 Sensors

Measurements in CIP Systems

The economic use of fresh water, as well as the multiple use of cleaning solutions, present a further basis for achieving overall cost reduction in line with the strive for greater efficiency of the brewing process. Here also, in-line systems are of help in monitoring and optimizing the relative sub-processes.

Measurements in Wastewater Treatment Facilities

Fouling of sensors in wastewater leads to uncertainty about the measurement results and can even result in measurement system failure. METTLER TOLEDO provides efficient and practical solutions in the wastewater treatment areas as well.
