Questions and Answers

This carboy thermowell is used in conjunction with the Digital Thermostat to more accurately regulate internal temperature during fermentation. It is exceptionally useful during the start of fermentation when the lag between ambient temperature in the refrigerator and actual temperature in the carboy can vary greatly. Now you can keep your beer or wine within one degree of the set point on your digital controller. Designed to fit either the 5, 6 or 6.5 gallon carboys, or any other similarly sized opening hole, the unit comes with an 15" stainless steel thermowell with a 1/4"ID and a #6 stopper. It can be used in any container with a stopper opening where you need to accurately monitor and control liquid temperature. You can use this with your refrigerator for exact cooling temps, or use it with one of our heating products to control how warm your fermenter gets.

Note: Not compatible with the analog temperature controller or Better Bottles.

Stopper

Works great. It is a little small. Goes in to being even with the top of the carboy but still seals.

Great Idea, Poor Implementation

As other reviewers have said the bung is made out of a silicone material and is super slippery when wet and is slightly undersized for the carboy I got as part of my kit. I tried all of the methods outlined in the reviews and in the questions section and could not get it to sit to my liking. Despite all this, the actual thermowell is well made and the entire kit is less than most places sell just the thermowell for. I decided to take the thermowell out of the bung and am going use a grommet in the plastic fermenter lid instead.

Very useful, but a little finicky

Several reviews say the diameter is too small. I found it fits perfectly when you insert an airlock, as long as you make sure the stopper and the neck of the carboy are dry. If either is wet, the stopper will slide out. Well worth the trouble to get accurate temperature during fermentation.

Reviewed by: Steven from United States on 2/8/2019

Perfect

Other than stopper wanted to keep sliding out, a little duct tape handled that. It worked great.

Useless as is

The stopper is way too small. This is essentially useless as is with any standard 3/5/6 gallon glass carboy.

Reviewed by: William Selent from on 1/2/2018

Works as expected

I am giving 5 stars because after three batches maintaining perfect temperature using the thermowell and temperature probe was exactly what I expected. As far as the stopper that comes with the thermowell, I just removed it and drilled an additional hole in a larger stopper and inserted the well. Too easy!

Slightly small but works

The stopper is smaller than I'd like but I'm not worried about it going through the hole in the Big Mouth Bubbler lid. Other than that, great item so far.

Works Great!

I used this for a thermoelectric cooler I built. It is large enough to fit the standard temperature probe on the STC-1000 controller.

Reviewed by: Chad from on 6/13/2016

Great product

I installed an stc1000 probe and retrofitted it to my fermentation bucket. Is also easy to bend if needed.

Excellent Product, Great Price

These guys have the best prices and the best service. They exceed my expectations every time!

Stopper Thermowell

Works Great! Inserted the probe into the thermowell once the wort temperature was close to my fermenting chamber temperature and allowed the compressor to be controlled by the wort temperature.

Reviewed by: Jereme from on 6/18/2015

Buyer beware

The stopper is too small. When wet it slips right through the carboy hole. After this happened to me I had to leave it in the beer during fermentation. The silicone-like stopper released some solvent or something into the beer and it smells bad. Had to dump the batch.

Reviewed by: Dave from on 6/9/2015

stopper is very slippery

the stopper is not made from the same silicone as other stoppers. It's very smooth and difficult with a glass carboy. It almost slipped into the carboy and conversely slipped out far enough to not keep a seal during fermentation.

Reviewed by: Michael from on 5/23/2015

It broke

The rubber stopper part split down the side (closest to where you insert the airlock) on the second use/beer I made. Not happy with that. Otherwise, it works like it says it should.

Reviewed by: Tyler from on 1/25/2014

Much Better Control

The combination of the carboy heater wrap, thermostat control and thermowell stopper allows me to ferment at a constant temperature. I have much better control over the fermentation process and I think that makes a better beer. I''m quite happy. Cheers!

Q: What is the length of the thermowell's extension below the stopper, i.e. when the end of the ruler is placed flush with the bottom of the stopper?

Asked by: Roger Placer - 12/25/2020

A: the length of the stainless tube end to end is 15" so the overall length of the full stopper and tube is 15" in total

Q: does the stopper still have a blow off tube hole? I'd like to tie in an Inkstop and blow off tube in the same bung on a 5 gallon glass carboy.

Asked by: rock morey - 2/1/2019

A: The stopper will have a 2nd opening into the carboy for off-gassing in addition to the thermowell opening

Q: Hello AIHB, I am looking for Stopper thermowell that is only 10 inches long. a Thermowell to be used in a 1 gallon jug. Do you carry any SHORTER thermowells? thanks

Asked by: steve - 10/9/2018

A: At this time the longer stopper thermowell would be the only one we source. We will keep an eye out for a vendor with shorter designs to possibly add in the future!

Q: Is there a way to use this with a standard 7.9 gallon plastic fermenting bucket?

Asked by: Brian - 8/27/2016

A: Yes, You would just need to make the proper modification to the lid of the bucket to accommodate either the thermowell tube it self or the bung the thermowell is attached to.

Q: Is the thermowell flared out at the top? I'd like to use this as a thermowell in my corny keg and was wondering if it would seat on top of the standard dip tube port.

Asked by: Sean Malloy - 8/17/2016

A: The Thermowell is flared out on top, though it is too small for the keg port. The tube is also crimped on the bottom end and cannot fit through the port either. I do have a secondary fermenting lid available that will fit the Thermowell. Here is the link to the product.

Q: I just received my thermowell and am worried because it continues to pop out and will not seat. the stc-1000 probe fits perfectly but the bung is loose. is this a problem? any solutions?

Asked by: Stan Kendall - 7/29/2014

A: As long as the stopper is seated on top of your carboy then everything is good. A tip on getting it to stay in the bung hole would be to get the glass and the bung as dry as you can before inserting the bung, sometimes if the bung and the carboy are very wet it will have the tendency to pop out.

Answer provided by: Old Ale Jay (9/20/2013)

Q: I'm reading reviews where this item doesn't fit the 6.5 gal carboys too well. Also, I saw a review that said it doen't work with the Johnson Digital (blue) controller. Any thoughts on that? Couldn't I just sanitize the the probe and wire on my controller and let the tip dangle in my brew?

Asked by: Brian - 9/20/2013

A: If you put the airlock in the stopper first then place it in the carboy it fits no problem. We have found that #7 stoppers with the thermowell and airlock bulge out too much to fit in a carboy. The old models of Johnson controllers did not fit. Recently they have changed the probe and it will fit this thermowell.
