Fermometer - Adhesive Thermometer

THIS ITEM IS ON BACKORDER
Item currently out of stock
Description

Liquid crystal thermometer which adheres to the side of a carboy, bucket, or even stainless conical to tell you the fermentation temperature. 44–86°F range (Fahrenheit only, not available in Celsius). This has always been one of our very best selling products.

What we really like about this unit, called The Fermometer, versus generic versions that are slightly cheaper is the more precise scale of 44–86°F. We also appreciate the handy suggested Lager and Ale temperature ranges printed right on it. An example of the more precise scale would be that on this unit it easy to tell 1 degree of difference, say between 72° and 73° degrees. The more generic units can sometimes jump 4 degrees.

Savvy homebrewers know that even 1 degree of temperature difference can have a big affect on the final flavor outcome. You may or may not have control over temperature but it is still helpful to know the exact fermentation temperature and to log it in your records.

great value and works just as well
My old strips finally bit the dust. These are super helpful keeping an eye on fermenting temps here in Central Oregon. I heat with wood and wrap the carboys in a polar fleece zip up. I can unzip, take a peek and see how my brew is doing.

Best Stick On Thermometer Yet
This is much more granular than most stick on thermometers. It works very well with my plastic fermenters.

Must Have
This item allows me to guage temperature in the primary without opening the lid. In conjunction with airlock activity, I can keep a close eye on expected behavior. Recommended!

Good Thermometer
Only drawback is it is hard to separate the backing so it sticks. It should have a perforation
