Back on track - I saw this product up close and personal at a competition and it is both a great idea and well made!

Haven't yet figured how to keep the lid weight off the airlock when using a glass carboy. In a bucket I just stick something taller than the airlock on top to prop up the lid.

I can usually easily achieve 7-8 degrees below ambient temp. With a little care and effort I can achieve 10-11 degrees below.

I've learned to predict temp swings and add/remove frozen water bottles as need. My last beer I managed to keep a constant temperature of 67 degrees F for a solid 14 days. One time it went down to 66, and up to 68, but for no longer than an hour or two.
Try a pvc pipe around the neck of the carboy.

Thanks for the clarification guys. I guess I didn't quite understand how that worked.

It's nice to read all the great reviews about this product. I am definitely thinking about getting one myself.

I love it for fermenting lagers. Just fermented a smoky Octoberfest beer. Reached FG in 10 days, and the hydrometer sample tasted so good I almost don't want to wait to the fall to drink it, but I will be patient and lager it in my kegerator.

Honestly, you could probably fit three 3 gallon carboys in one cooler. Might not be a need to make them smaller.

Hi,

Thanks for the request.

We are working on a 3 gallon size with our supplier. Once we get a firm date to be available we will be sure to let you know!

Ordered one of these over the weekend; it should be delivered today.

I'll be brewing this weekend, and had a question. Should I start cooling as soon as I pitch the yeast, or wait until fermentation has started? This will be my first attempt at controlling fermentation temperature, and I'm nervous about cooling too much, at the wrong time, or inadvertently causing temperature fluctuation. Thanks for any thoughts.

I would start cooling before you even pitch the yeast. Most of the off flavors produced by yeast at the higher temps are at the start of fermentation (the growth phase). So you really want it at or slightly below your desired fermentation temp before pitching and then hold the fermentation temp you desire. I typically pitch about 5F below my desired fermentation temp.

I cool the wort to pitching temp before transferring to fermenter and before putting the fermenter in the bag. The cool brewing bag does best at keeping the wort cool. It is not as good at cooling the wort from a higher temp. It can be used to cool the wort but it is much slower than a wort chiller or ice bath.
