BrewJacket Immersion Pro

Kept the wine well within desired temps, even during active fermentation. Be sure to buy sleeves if using for winemaking. Hint: Tape the temperature probe to the fermenter before placing into the insulated sack.

Brew day arrives, get everything started, plug in the BrewJacket power supply and... no juice. With the big day already under way, there was no option of returning the unit for replacement, I needed it NOW. A simple commitment to quality control, like plugging in the power supply before it left the factory, would have saved a paying customer a world of grief.

Got this for Christmas December 2020 and by June the AC/DC adapter failed. Prior to that it was amazing, freeing up fridge space and allowing me to brew some excellent warm kveiks and chilly lagers.

I tried yeast at hot summer temps and they worked fine at temps over 85 degree. Less than that my lagers and pilsners weren't that great. With Brew Jacket I can get great results at the correct 50 degree temp. It holds the temp you need and now my pilsners and lagers turn out. Easy set up wonderful results. Wish I purchased sooner.

This works great keeps temperatures with (.2-.3) its a bit of a pain to have to have the custom lids, and taking the lid off for dry hopping for example when this is installed... The big thing is I feel like the price point needs to be more around 100$ because I can buy an inkbird and a heat wrap and use my cold basement for around 60$

Like other reviewers, I don't have the space for another a lot of equipment, and this unit allows me to ferment at precise temps below room temp. It's easy to set up, doesn't take much more space than the fermenter, and you can get different fermenter lids from the manufacturer for a reasonable price. I've bought two so I can lager beers while I ferment another!

This device does exactly what I expected it to do. Unlike others, I didn't buy this to brew lagers, though I think I could if I wanted. I live in Florida with no basement, so I got this to keep my ales in the low to mid 60s range. My house's ambient temperature is around 74 degrees year-round, and this device easily lowered the temperature into the range I required. The variation on the temperature I set was only +/- 0.4 degrees. That's pretty tight control if you ask me. I think the secret is to limit your expectations as to what this can do, and think realistically if it's possible to cool 20 to 25 degrees when the ambient temperature is 85. Maybe it can, but I think this is best used in scenarios where you need +/- 10 to 15 degrees. Also, unlike others, I did my research and actually contacted Adventures in Homebrewing before I bought one. That way, I had a fermenter that worked well with this...only needed to drill a hole for the blow-off tube.

I don't know if this product works. Be sure that you have the adapter for your fermenter, or you've bought a paperweight.

Realistic temp when cooling is 12 to 15 degrees F of room temp when you have active fermentation. So if you want to do lager at lower temp like 50 you have to pre chill your wort to 50. If you do an active starter and let's say you pitch at 55 it won't be able to bring the temp down if your room is at 70/72. I guess it will be good to do ales if you keep your house warm as mine.

I LOVE this product. I don’t have space for a fermentation chamber, and this takes up just a bit more space than my fermentors. I have been able to maintain 72F while my house is in the 80s and it’s awesome. Fan can get a bit noisy, but as long as you keep it in an area where you aren’t trying to sleep, it’s really no problem. More of a gentle hum in the background and you forget it’s there before too long.

This may be a great product, but I may never find out. Even though it says it's compatible with Better Bottle, it isn't, and if you want to use it with a brew bucket you need a special lid - which is out of stock everywhere. Hopefully someday I'll get to try it out.

I am Enjoying using the brewjacket, it is currently warming my all grain Irish red ale.. While it is pricey, it really helps for those who have space issues, or don't have a Fridge. Fan is a little loud, but as my fermenter is in the garage, its out of the way and doesn't bother us. Very impressed with this little unit. I would say if you looking for a cooling / heating system, and do not have space for a fridge, this little unit is all you need. Kit comes with jacket, blow off tube, and two protection sleeves.

Recently purchased a Brewjacket, it's arrival spurred me on to do my first all-grain batch of a Czech pilsner recipe. I lack much brew storage space in my house, much less one for a lager fridge, and what space there is available is warm. The Brewjacket is perfect for my needs. Equipment set up is very easy. Important: read the PDF online manual - temperature calibration is important. Follow instructions to sanitize the probe, the metal bar, and the PET container (in my case, a 6-gallon carboy). The supplied temperature probe was spot on with a freeze/boil water test; the manual does guide one on calibrating the controller head, if necessary. After attaching the unit to my batch in the carboy, I was able to snuggle the carboy with 5 gallons of wort into the jacket without too much difficulty. (Tip: use a carboy strap hauler to insert the carboy into the jacket with a straight, downward motion into the jacket cavity). The controller, when it's running, is a bit loud, so keep it at some distance, close the door, or shove it in the basement. My impression is this item, though expensive, is perfect for my needs. I won't be making a lot of lagers, mostly ales, so this single unit is all I (think I will) need. Glad I bought one! Apparently, the company now makes jackets to fit FastFerment and SS Brew Ferment Chronical 7.
