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.

Seemed like a good idea. I have a probe in the fermentation chamber (chest freezer), but thought it would be a good Guage of actual wort temo

Easy to apply to my plastic carbouy. I have a couple of these fermometers on other fermenters and I trust the readings.

Adhesive thermometer
I like these that sit horizontally to the surface of the beer. I think it is more accurate. It gives the average by placing it halfway down from the top. JMHO

I would send a pic but I just (5 minutes ago) finished a second bottling session and I am pooped. Maybe next time.

Good for carboys
Nothing fancy here, just stick it on and go. At least now I know what the carboy temps are. It's amazing to see the temp difference between an active carboy versus one settling. I thought there would be a difference, but six degrees? Wow! The two carboys are six inches apart in a big plastic tub.
