Stopper Thermowell Review

Customer Ratings:

I use a 6.5 gallon carboy as my primary fermentor. The stopper that this thermowell comes installed in is just a little undersized for the 6.5 gallon carboy. It is almost flush with the rim of the carboy mouth when it's inserted tight enough to ensure a seal. The stopper appears to be made of a dense foam and I noticed if it was wet when inserted into the fermentor it tended to pop back out unless it was really pushed in there hard. I actually pulled the tube out of the stopper and installed it in another cap I had with two holes in it. Maybe I'm being too picky about sealing the carboy but I know I would worry about it if I used it the way it came. The transaction with the seller was good though.

I just started using this in my controlled fermentation chamber & it works very well. It allows my Johnson Controls regulator to slide right in & take an accurate reading from the middle of the wort in my 5.5 gallon carboy. It fits perfectly into the opening. I honestly can't see a problem with this. I imagine if you had a larger carboy it could be a little small but for most batches for most homebrewers this works just fine. No complaints here. It also arrived early!!

I brought this so that I could regulate my fermentation temperature. After the 1st month I went to rack mead into the secondary and the well was full of mead and my temp probe was ruined. The mead was bad and my investment in the whole thing was gone. 5 gallons down the drain.

Great product. Works great just like advertised. Buy this & the blue honeywell electronic digital temperature control A419 blue unit! the thermo-well is the perfect size for this controler.

I used this product only a little before I bought a hood thermowell from a different site. I like the size of the thermowell and how long it is, but I found myself having trouble keeping the stopper part secured in the carboy. StarSan makes it slippery.

It's an ok product and does what it is meant to do, I just prefer my hood thermowell more than this.
