We are working on heating right now as the technology is capable of it, but there are many engineering issues we need to work through to ensure it works properly. That said, all of our units are upgradable. When we are ready with heating, it will be as simple as unscrewing the top panel and...

Not on traditional glass carboys, but if you wanted to use a Big Mouth Bubbler from Northern Brewer, the hole in the top can be altered to accommodate Immersion.

Energy consumption is 90w while cooling

We are handling co2 release through a bulkhead connector mounts into the neck of the Better Bottle. You can either drill a 1/2” hole into the neck or pick up a pre-drilled better bottle from us to mount the bulkhead connector. We are also including blowoff tubing and a one way co2 release valve...

Very close - be on the lookout for big news from us by next week.

Quick update: we've announced a $299 model that uses hard anodized heat transfer rods instead of stainless steel. We've been experimenting with hard anodized rods for a while now and they hold up very well over a lot of ferments (so far +/- 30 over 2 years). They require a bit more care than...

It is peltier-driven, and as such you are correct that the chips do not produce as many BTU/hrs per watt as a compressor system. The system does however consume 90 W, and it does indeed get your fermenting beer to 35F below ambient. Here is how: 1. We're cooling just the beer, not the air...

I wanted to float an idea by the community that we've been discussing internally. We are very interested in splitting the system up and allowing people to purchase individual components, allowing it to become more of an open-source system. For example if you already had a temperature...

The current plan is to retail them for $399, as the raw materials alone far exceed $150. One very important thing to note is The LagerJacket uses 90w of electricity. If you were to run it 24/7 for a year, it would cost you $24 in electricity. If you did the same with a second hand chest...

We haven't built heating into the system, but it is something that the tech is capable of. For the first version we are concentrating on cooling without complicating our electronics, but in future versions, this is something we are very interested in including.

Our Kickstarter just went live a few minutes ago! http://www.kickstarter.com/projects/433436998/the-lagerjacket

We've been around since 2011, but mainly doing development and testing. The project started off as a way to brew lagers in a small hot apartment in Atlanta, GA, but grew into something far more substantial over the next two years. I've brewed around 30 batches of beer with it, and beer quality...

So the jacket is still alive, but development is taking a bit longer than expected (especially when you enroll in grad school half way through the process). We have a working prototype developed and have brewed close to 15 batches with it and I'm very happy to report that it works as advertised...

Thanks for all the great feedback everyone. The current design incorporates a thermowell so the temp is regulated from the center and not at the wall where the cooling is. So far as larger sizes, it's possible but will require further testing as power requirements will increase greatly with...

We'll have different jacket sizes available, so buckets won't be an issue.

Yes, the picture is an artist rendition of the final design. We'll update the site as we progress.

That is correct, we have working prototypes, but before we make the move to manufacture we need to know if it makes sense to even go that far. In which case the feedback here, unless we can get it down to 32F, it won't be as valuable to this community.

The adjustable ranges would be a maximum of a 15 degree delta on the lower powered jacket, and 30 degrees on the higher powered jacket. So for example in the summer here in Atlanta we get temps of 90-100 outside, with indoor temps ranging from 75 - 80. The lower powered ale jacket would be able...

Hey everyone, Aaron with Lager Jacket here, sorry for the confusion on the price, we're using google web optimizer to test the reaction to different price points. The jacket is still in its testing phases and we're seeing which price and feature set are most popular. We essentially have two...
