Listening for a Strange Brew
Researchers at the Pacific Northwest National Laboratory (PNNL) have devised a way to quickly measure and track the quality of fermenting liquids, such as beer, without having to draw samples from a batch. Sampling fermenting liquids is necessary to ensure quality, but it can be time-consuming and potentially contaminating. By using ultrasonic backscattering, a method of reading sound signals as they bounce off targets and back to a sensor, the PNNL team's system avoids these drawbacks and gives the brewer greater control over the fermenting process.
