Fermometer™

Adhesive backing for attaching to outside of plastic or glass containers for accurate inside reading.

Newly redesigned, the Fermometer™ has a higher overall range (now 44-86) and added suggested range bars for red & white wines and Belgian Ales.

Strip measures 1" wide by 8" long.

Once you stick this to your bucket or carboy, don't try to remove it. You'll mostly destroy it, mostly.
