Brew better beer with a fermometer! Fermentation + thermometer = fermometer. This low profile adhesive strip thermometer provides an accurate temperature reading when applied to your carboy or fermenter. Proper fermentation temperature is important for getting the best performance from your yeast. The ale yeast strains in our beer recipes prefer a temperature between 60 - 75 °F. Too cold & the yeast will go dormant. Too warm and the yeast can create off-flavors. Better tasting homebrew starts with taking control of fermentation temperature. Look for the greenest temperature reading on the adhesive strip thermometer to see whether your beer’s fermenting at an appropriate temp. Unlike many others, our fermometer displays both fahrenheit & celsius. Plus, its small size (.75” x 4”) means less clutter on your fermenter.
