Brewers need to constantly manage their storage supplies to ensure they meet the highest fermentation process to achieve customer satisfaction. While brewers conventionally rely on sampling as quality control, these procedures merely provide a snapshot of the product condition and may present inaccurate results.

The methods of analysis outlined by the American Society of Brewing Chemists (ASBC) help brewers avoid contamination. However, it might still fail to accurately represent the microbial or chemical composition of the beer within brewery tanks. Some commonly overlooked contamination risks include opportunistic microbes found on sampling ports and corks.

Real-time Monitoring – A Dynamic Alternative to Sampling

Precision Fermentation’s BrewMonitor® offers the industry’s first comprehensive real-time remote fermentation monitoring system that overcomes the limitations of sampling processes. The revolutionary alternative provides brewers with accessible fermentation data through the unmatched convenience of IoT technology.

Real-Time Brew Monitoring in Action

Precision Fermentation’s systematic approach involves ongoing monitoring of seven key metrics in fermentation data that determine product quality. These factors include dissolved oxygen, PH, gravity, pressure, fluid temperature, ambient temperature, and conductivity. By linking with Precision Fermentation’s BrewMonitor system, brewers can receive a stream of detailed real-time updates of their product quality from the comforts of their registered mobile devices.

Dissolved Oxygen

Dissolved oxygen (DO) is an important component in a product’s quality and shelf life. Brewers need to pay close attention to the DO of their products during the fermentation process to provide customers with the ideal tasting experience.

Precision Fementation’s system accurately measures DO during various brewing stages for comprehensive logging. For instance, brewers may check for DO after dry-hopping to determine the cause of excess DO levels.

PH Levels

PH levels at various stages of brewing can have a significant effect on the final product. Precision Fermentation’s real-time BrewMonitor solution enables brewers to closely monitor pH levels as a part of actionable fermentation data.

Constant pH gauging helps prevent a beverage from going off-flavor. Sampling processes may lack the granular monitoring required to detect the shifts in pH throughout fermentation, where variation in values can influence the quality of the final product.


The gravity of the beer is a critical metric during the fermentation process. Precision Fermentation provides brewers with comprehensive real-time measurements of gravity levels for specific phases in the processes. Gravity monitoring helps brewers get early indications of something in the process gone awry, but can also provide useful longitudinal data that inform the health of fermentations.


Precision Fermentation’s BrewMonitor offers an accurate measurement of pressure levels in beer supplies and reduces ester production and fusel alcohols that result in off-flavor effects. With Precision Fermentation’s direct fermentation data stream, brewers can closely monitor their pressurized fermentation systems to ensure consistent production across their supplies.

Fluid Temperature

Brewers can expect the Precision Fermentation system to consistently monitor fluid temperatures across their brews, helping ensure greater consistency. BrewMonitor helps reduce labor requirements, but brewers drive a lot of value from the early indications of an issue that the system provides.

Ambient Temperature

BrewMonitor not only provides real-time data about the fluid temperature but also keeps tabs on the ambient temperature in your brewing environment. Being able to track the ambient temperature and respond to changes, or simply look back at the impact these changes have had on batches over time, is yet more data that contributes to achieving consistency in your brewing process.

Electric Conductivity

Precision Fermentation’s BrewMonitor gives brewers a precise observation of liquid conductivity, necessary for measuring water purity. The constant measurement of ion levels in brewing enables brewers to assess the acceptable amount of additives according to water purity levels, matching suitable quantities for desired results.

Advantages of the Precision Fermentation Method

BrewMonitor provides brewers granular control over their product quality through real-time monitoring and analysis of the fermentation process. The intuitive use of the platform enhances product quality through process control that pairs compatibly with existing brewing systems.

Access Substantial Data Points

Brewers will receive approximately 1,000 fermentation data points from the BrewMonitor per day per tank monitored, providing an in-depth assessment through an active sampling of their brewing systems.

The accurate database enables brewers to review and improve existing processes for greater product quality and profits. Brewers may also choose to customize fermentation thresholds with built-in alerts according to their products’ desired taste and aroma.

One-stop Reference

The BrewMonitor offers a user-friendly dashboard that allows brewers to view all their data needs from a single page. A mobile-friendly cloud-based design optimizes the BrewMonitor dashboard across all mobile devices for fuss-free reference on the move.

“Backward Compatibility”

BrewMonitor operates as a fully SaaS-based product that brewers can conveniently integrate with existing tank ports and does not require tedious software installations to enable the generation or viewing of data.
