Welcome to All Sensors “Put the Pressure on Us” blog. This blog brings out pressure sensor aspects in a variety of applications inspired by headlines, consumer and industry requirements, market research, government activities and you. In this blog we’ll discuss pressure and the role it plays in creating great beer.
The Pressure to Make Great Beer
Temperature and time play critical roles in the brewing process. In addition, commercial beer making involves the use of several pressure sensors to monitor different phases of the process. Various stages of brewing, including mash and wort (the liquid extracted from the mashing process), require careful monitoring and a brew kettle may have gauges for operators.
According to one authority, “Most breweries use a steam-fired kettle, which uses steam jackets in the kettle to boil the wort. The steam is delivered under pressure by an external boiler.” Monitoring the pressure requires a pressure sensor. Other steps in the process flow are also candidates for sensing pressure. According to Wikipedia, steps in the brewing process include malting, milling, mashing, lautering, boiling, fermenting, conditioning, filtering, and packaging.
Automated processes provide greater consistency and control of brewing or any food processing and require electronic sensors. Automation is even used for home brewing. One product called the Brewtroller uses a proportional-integral-derivative (PID) controller or on/off switches to control heat outputs, pump and valve outputs. It also employs a variety of sensors, including:
- Six temperature sensors
- Three optional volume sensors (pressure transducers) to measure the hot liquor tank (HLT), mash and kettle volumes
- An optional steam pressure sensor for controlling steam heat
Another new product, Lyon Labs’ BrewNanny uses an automated seal to release the carbon dioxide produced when fermentation takes place and to prevent air from entering the container. The seal has an embedded 32-bit microcontroller, a pressure sensor to monitor C02 and other components to improve the home brewmeister’s product.

The BrewNanny displays brewing parameters in real time on the BrewNanny Dashboard through a web browser or custom apps for Apple and Android products.

As in many industrial and medical applications, pressure plays a critical role in monitoring and control. With my own favorite brew in mind, Prost, Skaal, Cheers, Salute, Kampai or whatever your toast is — enjoy.
