Fits the top of the Big Mouth Bubbler perfectly, and really has helped to have more control over the primary fermentation. Before I bought this, my Cider would come out to 4.2-4.5 ABV, now I can get 6.5-6.8 by using this with the Temp controller and probe.
This product is a must! It is an excellent product that I highly recommend to all DIY winemakers!
I really like the idea of having a thermometer in my beer as it ferments, but this sadly isnt a solution. I cannot for the life of me get a good seal on this. It either leaks from the sides of the Bung or from where the thermowell attaches. I have tried Candlewax to hopefully seal it up some, but that didnt seem to help much. The Bung itself is a harder rubber like plastic (Like TPE if you ever 3d Printed) and like others have said, the hole for the bubbler is TINY. I had to jam my PLAATO in there, and i cannot get an accurate reading from that at all.
At a loss. I really like the idea, but i think it needs some work.
Works great with my plastic fermenter and carboy. Has to get an S bubbler to fit with the Thermowell. But it works great.
Stopper does not fit standard carboy. Would not recommend this product.
We've tested this thermowell and found it to be compatible with our 3, 5, 6, and 6.5 gallon glass carboys. There is a lot out there in terms of carboys, especially with older ones that have been around for decades, and some of those may have different opening sizes. Please contact us directly if the fit is poor on one of our carboys, and we'll be certain to help get things straightened out. We can do a return, otherwise.
