BrewJacket Immersion Pro

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.

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.
