Home Brew Fermentation Cooler Bag

[an123]

Just purchased a Home Brew Fermentation Cooler Bag. Has anyone here ever used one of these. I am just getting set up for all grain brewing. Didn't want to spend the money on a refrigerator for it. Maybe in the future I will but wanting to know if what I bought will actually work.

not sure. There is one particular brand that is highly rated, though I forget the name now. Purchase hindsight is always 20/20.

I have two of the Cool Brewing fermentation bags. They work very well at keeping fermentation temps down.

I have never used one, but there are many options out there regarding fermentation temp control. if I didn't have an awesome basement (see "It's a secret!!") hole temp of 50F or a keezer, I would be looking at other options myself. let us know how well it works for you!

Do you add ice bottles to it periodically throughout the fermentation process?

 

[Jeffinn]

Yes, I use frozen 2 liter soda bottles and swap them out every 24 hours as needed.

 

[an123]

How many of those bottles do you put in the bag to. Hold temperature.?

I'm currently using one on a pale ale I brewed up 1.5 weeks ago...works great!

 

[an123]

What temp were you holding? And how many bottles were you keeping in there ?

 

[tlucarelli]

Nevermind. Ignore my post.

What temp were you holding? And how many bottles were you keeping in there ?

I use two 2 liter seltzer bottles...I held 61-63 the entire three weeks changing out bottles every 12 hours!

Cheers!

I'm currently fermenting a Rogue Dead Guy in a Cool-Brewing bag.

It needs to ferment at 60 degrees and ambient temps are in the low to mid 70s in my house

I'm using a water bath and dropping 3 small water bottles twice a day. It's a doing a great job.

I placed the cooler bag in a rope-handled bucket to keep the stress on the bag down and a container in case of a leak. It ended up leaking, but I contacted customer service and got a quick reply. There are sending a replacement and letting me keep the original bag. I'm very pleased with that interaction and the performance of the bag (despite the leak)

I went with the frozen two liters. 4 of them keep the temp around 65 all day

What was your ambient temperature? Outside of the bag.

That just sounds wrong.

70-75 degrees

I just bottled an IPA that I cold crashed in this bag.
The cooler bag and IPA were in a room whose ambient temperature was 52 degrees.
I had six two liter frozen water bottles that I would swap out periodically to keep them good and frozen.
When I racked the beer to a bottling bucket it measured 36.5 degrees and was quite clear.

The bag works great

Yeah I'm happy to know I can ferment, cold crash and lager in it if I want.
