Data Loggers in Breweries

As Beer City USA, breweries have taken over GR and the rest is hops, beer, and history. Each brewery has perfected their unique process of craft beer production. To ensure quality and the individualistic taste, which sets each brewery apart, data loggers are used throughout the production process to monitor and record different factors such as CO2, Pressure, Humidity, Temperature, and pH.


Carbon dioxide is given off by yeast during fermentation, it is used during the bottling process, used to give beer carbonation, and to allow extended shelf life. CO2 is a naturally occurring chemical compound; however, in large amounts, it can be toxic. In breweries, the maximum permitted carbon dioxide concentration is 5%  during an 8 hour period. To protect the production of your product as well as the health of your personnel, it’s important to track the amount of CO2 being produced.


Temperature is monitored throughout the entire process, but it is particularly important during the mash, fermentation, and pasteurization processes. During the hot water steeping process, malt enzymes are activated producing sugars. During the fermentation process, sugars are broken down by yeast. Yeast is greatly affected by temperature. Too high of a temperature can cause the yeast to grow in abundance, and too low of temperature could cause the yeast to go dormant. Pasteurization is the process of heat-treating beer to inhibit the growth of microorganisms. One will want to closely monitor the temperature to ensure a consistent taste within their product. Minimal differences in temperature can greatly affect the quality. For this reason, high precision and accuracy are needed in the process. Thermocouple sensors aren’t accurate enough for this application, but data loggers are.


pH is also monitored to maintain a consistent taste. It is often measured during the water treatment, malting, lautering & sparging, boil, fermentation, and yeast washing processes. Many reactions take place during the production of beer, most of which are sensitive to pH. To finer tune the individualistic taste, pH can be a useful tool to adjust and monitor. Using an automated, highly accurate, wireless system to record, monitor, and track your data is very labor and time effective. Data Loggers have alarming capability to inform you of any variance and allow information to be tracked in real time, to allow you to make any necessary changes before a batch is ruined.
