Keeping the right temperature during the fermentation is essential to the performance of your yeast. Imagine being able to just glance over at your fermenter and instantly know what temp it’s sitting at. With the Fermometer you get just that! It is a liquid crystal thermometer that adheres to the side of a carboy, bucket, or even stainless conical to tell you the fermentation temperature. (Fahrenheit only, not available in Celsius.)
What makes it a favorite among homebrewers is it gives you a more precise scale of 44–86°F, which the cheaper generic brands do not. It also has suggested Lager and Ale temperature ranges printed right on it. An example of the more precise scale would be that on this unit it’s easy to tell 1 degree of difference, say between 72° and 73° degrees. The more generic units can sometimes jump as much as 4° degrees.
Savvy homebrewers know that even 1 degree of temperature difference can have a big affect on the final flavor of their beer. And even if you don't yet have control over temperature, it is still helpful to know the exact fermentation temperature and to log it in your records.

Works, but does not hold up to moisture
I wanted to get something to help monitor the temperature of a 6 gallon carboy, but this thing does not want to stick once it gets wet. It just comes right back off again.

There are no instructions, and nothing else came with it. I'm assuming if the temperature inside the carboy is reached on the strip, it shows a color. But what do the colors mean? Who knows. I'm sure I'm the novice idiot minority here among home-brewers, but you'd think they'd simplify it just a bit for those of us that aren't masters of the art yet.

Response from MoreFlavor
Thank you for your review and we apologize for the confusion with this product. The colors are just there to highlight the temperature range. If three numbers have colors underneath them, then you are in the middle of that range. If just two numbers are different colors then you are just in between those two numbers. Hope this clears up some of the confusion. Cheers!

Decent and accurate
I got this to add to my carboys as the stickers that were on there were too hard to read. These are pretty accurate for what it is. Matched up with a temp probe inside and they are within a couple degrees. The adhesive could be a little stronger, but a hairdryer and rubbing seemed to get the edges to stick better.

very handy device
This is very convenient to have adhered to the side of your fermenter to get a sense of the temperature. It's accurate enough to know if you're in the range you want to be in. Not as accurate as putting a thermometer into liquid, but that would be a real pain and probably not more helpful.
