I use the grainfather counterflow chiller that was included with grainfather. Pretty good over the past 2 years. I love counterflow chillers because you can pretty much transfer your boiling wort to the fermenter and it cools along the way. Cheers and love your shop.

I just got an Exchillerator for my brewzilla. Would have gone with the kegland one if I knew it was out there. It cools down very quick. I'm in the San Francisco, CA area. I love the content you guys push out. Thank you!

I've heard very good things about the Exchillerator, that thing should last you a life time. Cheers

I think cleaning time should be added in the comparison. This can really add up with a counterflow chiller if you want to be thorough.

I usually recirculate pbw and water through the Brewzilla for 30min or so after each brew so I would just put the counterflow chiller inline and clean it it at the same time.

Super video. Just what I was looking for since I was wondering if I should go for a counterflow chiller. I currently use the standard one that comes with the brewzilla. Thank you for the super practical and useful content!

Ya the counter flow really helps getting down to pitching temps once you get around 30C (85f). Cheers

I made I own counter flow using 2 3/8” tubes in a 1 1/4 plastic tube. I can cool down to 50 degrees if I want to. With that it is gravity, fed right into my Fermentation container by controlling the water temperature and the flow of the beer reaching 68° ready to pitch right away.

I use an immersion chiller, but only about half of the coils are submerged. I have a small Anvil setup and would like to get a faster chiller. Currently it takes around twenty five minutes to cool 2.5 gallons of wort to 68.

I'm using the chiller that comes with the BZ gen4. Last time I used a low-medium stream of water from the hose, in order to waste a little less water. The pump is on 100% but even when using a full stream the performance isn't great. The manual also "kind of" suggests trying the Ice Bath method: pumping the wort through the chiller on an ice bucket. Haven't tried it yet but it SEEMS like it can be faster / waste less water. Of course you need ice but that's mostly planning. I'm not really sure about how much wort will be left inside the chiller tho. Anyway, will try this on my next brew.

I use the counter flow chiller that came with my Grainfather and am very happy with it. However, something that is never spoken about is the difference for the wort in terms of cold break. The immersion chiller cools the wort in the kettle to pitching temperature, so presumably encourages cold break to form and hopefully stay in the kettle. However counterflow chillers take the wort from say 80C to 20C in-line and deliver it into the fermenter. As a result plenty of cold break ends up in the fermenter. Discuss.

I always transfer pretty much everything into the fermenter regardless. Would be interesting to do a side by side brew with %100 trub into fermenter vs as little as possible. I know that people have tried this and found that beer with more cold break trub produced a more clear and better tasting beer than one with as little trub as possible. From what I've read you want at least some trub in there for yeast health since the trub is packed full of nutrients.

I’m in south Florida, our ground water is 80F. It takes more than 30 to chill a batch with a immersion chiller here. I might buy a second one and use some ice as a pre chill. But then again I can have most of my equipment cleaned in that 30 minutes. And I usually stick with warmer fermenting yeast during the heat scorching summers here since I don’t have temp control (yet).

@@Nefariousrouge I used a cheap pond pump and an esky (cooler) of iced water pumped through the immersion chiller recirculating (I did use the first 30 litres of boiling water for cleaning as I knew it would melt all the ice in a seperate bucket). Stirred the wart the opposite direction of the chiller. And we had it down to pitching temp in less than 15 minutes. And only really used maybe 80 litres of water and 3 bags of ice.

Counter flow wins for me, and its already ordered. Every time I put the immersion cooler in the boil my temp drops way down and I have to wait for boil to start again. counter flow wins because its not hooked up until boil is over. No removing hop spider until cooled. No fing around.

Awesome, let us know how you like it!

The only problem I have with the included immersion cooler is the diameter. My hop spider won't fit in it. Will a hop spider (mammoth brand) fit inside either of immersion types or would counterflow be better when using a hop spider? Just measured our cold water up here. 35.5f or 2c.

I just checked and the mammoth hop spider fits in the brewzilla immersion chiller. Counterflow is faster but is a bit more of a pain to setup.

​@@graintoglass when thermal expansion is added in it doesn't fit. Tried it last night in boiling water. It can be forced in, but I don't like splashing boiling wort. It sucks to get splashed. So I will be buying a new immersion cooler. The good part is this chiller fits my kegland 8l pet kegs perfectly. One small fountain pump and a cooler full of ice and water, one of my mini 360 regulators and a faucet or picnic tap and I have a portable system that doesn't need the cleaning after use that a jockey box does.

Hi, the way Kegland made the included chiller it sits higher up in the Brewzilla. If you are able to safely bend the arms up you could get it lower which would give you more contact area. Alternatively if you buy a different chiller they are usually design so that the chiller pipe goes straight up and then curves at the end which allows the chiller to sit at the very bottom of the Brewzilla. Cheers

Thanks Paul! Would copper(*) have made a difference (i know this was geared for Brewzillas)? And what’s the build dimensions for that handy workbench we always see next to the wall? *edit: typo on copper…not cooper

Hello, with coopers you don't have to boil anything so you wouldn't need a chiller. I'll have to measure the brew bench but I think it's around 6 feet wide and 2 feet deep on top and 4 feet deep on the bottom.

How you can filter counter flow? All unfiltered cold break trud comes to it. So more trud in beer which is meh. Cleaning it is also probably problematic. I'm newbie, pretty geek guy so learning everything but this one somewhat makes me think about it. Obviously one can put some pressure filter before the intake but that would clog up pretty quickly I guess.
