Product Details
Are you wondering if the BeerBug will work with your current setup?

The BeerBug works with any vessel to which you can add a traditional airlock and works great with all Big Mouth Bubbler® products. CO2 and krausen are rerouted through an airlock or blow-off adapter. Using the BeerBug means never opening your brew during fermentation again.

Connecting to your BeerBug is easy!

The BeerBug connects wirelessly to the cloud. Connect the BeerBug to WiFi just like your phone or tablet. As your brew ferments, periodically your BeerBug will send your data over WiFi. This allows you to view your data, in real time, anytime, anywhere.

We recommend pairing with the BeerBug Temperature Probe (not included) for the most accurate data.

Response from Northern Brewer
Hi John,

Thanks for the review. Beerbug informs us that they are working on the issue and they hope to have it resolved soon. Though, we do not know exactly when that will be.

Wait Until BeerBug's Service Improves
It really pains me to say this. I think this is a neat idea - but it needs major work to become a rock-solid option. For now, just take your hydrometer and temperature readings manually, and put your hard-earned $$$ into something else of brewing benefit.Vendor is plagued with infrastructure and service issues - and in the current permutation, you are fully dependent on them for things to work - there is no "local" option - it's all done in the cloud. Cloud services are great, but not when they are delivered at the detriment of product utility and warranty. In the grand scheme of things, they are in their infancy from a company and delivery point of view. If things drastically improve, I'll be sure to update my feedback. Vendor touts upcoming mobile app improvements, and I'm hopeful that their service issues will get straight. Until then it really hasn't proven to be worth the money.

Is 'thebeerbug.com' website dead?
I bought my Beerbug about a year or two ago. I've used it during all of my batches and it worked great. Until now. In early October, I brewed a batch and put my BeerBug on it, but it couldn't connect. I soon later learned that nothing was working at the server's website. Northern doesn't know what's going on either, but they acknowledged to me that the Beerbug server was not working. If I reviewed this thing shortly after I bought it, I would have given it 5 stars. Now, based on how long it's been offline (and the almost certainty that I now have an expensive paperweight), I'll give it a 2 star rating, teetering on a 1-star. I hope they get their server problems resolved, but I'm susicious that they don't care. They already have $200 of my money.

Response from Northern Brewer
We have been in talks with beer bug and they are hopeful that the issues will be quickly resolved. Some updates did not work as flawlessly as planned, but once they updated, the server should have improved functionality and reliability. They told us a week from this posting and it should be running and they are quite sorry for the issues and their delayed responses. Our customer service department is of course happy to help as well.

Would be nice if it worked
I see why it's on sale, it hasn't worked since I got it, I can't even register my account because the site is always down and won't even except my info. To proceed with registration, the support even sucks when you try to resolve it. If I were NB I would take it off the shelves.

Nice Concept, Lacks necessary reliable website for proper operation
I have yet to register my device after having this in my possession for almost a week now. Every time I attempt to go to the website to register it, the site is down. As I understand it, the website is necessary to be active for proper results. I would avoid this device unless the developers can maintain a reliable site. Note, I have tried to look around the site for 2 weeks with the same results. I was prompted to purchase with the $99 sale price but will be requesting a return. It's not worth the hours of constant trouble shooting I can see involved with the product and support to "make my life easier".It's very curious how come there have been no updates to the "fixes" on the website log since March of 2016 with all of the apparent complaints. Send back to R&D.

Why does Northern Brewer Keep selling these things if the website supporting them doesn't work
The Website/Database that runs these Beer Bugs has been out of whack for a while now. The units work fine when they can actually get data to/from the stupid web service that seems to suck right now. THE question is why is Northern Brewer allowing people to still purchase something that currently is unusable?

Could be good, but the website needed to use it is always down
I've owned my BeerBug for about 3 months. I was able to get through 1 brew with it before the website started having troubles which has rendered the device useless.Setting up the device requires using your phone to 'flash' your wifi settings using a custom app that flashes your phone's screen. I had some problems with this, but eventually found that if I turn up my phone's screen brightness and did the setup in a dark room, then it would work. There is a wifi status LED that blinks error codes at you if something is wrong, but there is no documentation to tell you what all of the different patterns mean. The included card only shows a few of the error code patterns.I used the Beer Bug for 1 fermentation. I found that the absolute SG readings weren't very accurate even after calibrating it. However, being able to see the relative changes in SG over time without taking samples is helpful. You can watch the curve of the SG graph and when it flattens out, you know you fermentation is slowing down. The built-in temperature sensor is not helpful since it's measuring ambient temp, not beer temp. The add on probe is a must if you want to see useful temperature readings.A few weeks ago, I went to use the BeerBug again and found that their website is down. I've been checking back and it will occasionally work, but it's down more often than it's up. You can see for yourself by going to https://www.thebeerbug.com/community/ and trying to get the live stats on any of the current brews. You'll usually get either no live data or a website error message. Without a functional website, the device is completely useless. I do find it irresponsible of Northern Brewer and parasitx to continue to sell these devices that don't have a working interface any more. They need to get their website issues fixed before they add more users to it.

Works great!
No problems with connection or anything else. Very easy to use and results are very accurate. It’s a great tool for tracking your brew.

Next level brewing
Stop guessing! I have used the BeerBug to brew a cider and an ale and they are by far the two best brews I have ever produced. The real advantage is that the bug was sending live info about temp and gravity to my phone so when I wanted to stop my cider before it got too dry, I just set an alert. I also never realized that the space I was storing my fermenter wasn't as temp stable as I thought. The BeerBug tracks it all and stores it for later reference. If you're serious about home brewing, this thing is a must.

No Support
Since I made this purchase, the web page has been down and the app will not connect. Seriously $149 is a large price for a paperweight. If the webpage does not come up soon or if the app does not work shortly (it has been 2 months) I am going to try and return this.

Will this fit a 2.5 gallon fermentation bucket?
L I on Jun 17, 2016
BEST ANSWER: Depending on the on the bucket, it may not quite fit in the grommet but you could remove the grommet or drill a separate hole in the lid. According to the manufacturer: "Holes that fit grommet sizes can easily be drilled into the lid without threatening the integrity of the brew lid. Please note it is slightly more difficult to steady the BeerBug when using a half inch grommet hole in the bucket lid."
Where does one get the blow off adapter shown in the photo? Is it included? Even the BeerBug website makes no mention of it.
T B on Jan 11, 2016
BEST ANSWER: There are two adapters included, one a right elbow for a vertical trap bubbler, the other a straight adapter with babed connector for blowoff tube.

FWIW I'm still testing my new units (3) - run eight days with still > 45% of initial battery charge, no data loss. Seems to work as (well as) described

Are you able to use this with a blow off tube? I brew a lot of stouts that tend to have high fermentation activity. I would think that this would be a problem, and was wondering if I would be able to use this or if they are looking to make this possible.
James J on Feb 3, 2016
BEST ANSWER: The BeerBug has an adapter on it that allows for a blowoff hose to be attached instead of a air lock.
Can you use multiples of these in the app to monitor each batch separately?
J O on Dec 27, 2015
BEST ANSWER: Yes. You can have multiple bugs running at once. You need a strong Wifi signal. I returned mine because it would not sync with my Wifi. Not compatible with Tp-link range extender.
Is there a special bung or stopper required to accommodate both the BeerBug and air lock or tube? If so, is it included?
Iamharrythehat on Dec 1, 2015
BEST ANSWER: The beer bug is designed to be used in standard openings so any bung stopper or grommeted hole with work with the beer bug! I hope this helps! Cheers! James J.
Would this work for one gallon batches?
Tony C on Nov 26, 2015
BEST ANSWER: I think so, the weight is approx 5 inches long and suspended in the wort with fishing line. So as long as there is 8 inches clearance between bottom of air lock and bottom of fermenter you should be ok. Another issue might be is the diameter of weight is 1.25 inches wide. So if your using a gallon wine jug might not fit through neck of bottle.hope this help.
What powers the unit? If batteries, what type?
Jason M on Nov 14, 2015
BEST ANSWER: It charges through a micro USB port. There is an included cable, but you will need to provide a power source. I'm using an old cell phone charger wall unit. There are no batteries required.
Will this work with a conical fermenter? I generally brew 12.5 gallon batches and have a lot of head space, maybe 2.5 gallons worth. I would say that's roughly 12 inches of empty space between the top of my conical and the wort. Cheers.
Matthew S on Nov 28, 2015
BEST ANSWER: As long as the fermentor has an opening similar to a standard carboy and the level of the wort is high enough to submerge the probe then it will work fine.
Will this work with wine making?
Jeff G on Oct 27, 2015
BEST ANSWER: The BeerBug works for wine making

it reads a gravity range of .900 to 1.300
Do I also need to buy the $39.99 temperature probe, or is that included?
N S on Oct 19, 2015
BEST ANSWER: The beer bug will sense the ambient air temperature. If you get the add on probe it can read the actual temperature of the liquid which improves its accuracy.
Does this need direct contact with the wort?
S T on Oct 18, 2015

but the sensor unit itself does not contact the wort. The included "torpedo" is suspended from the sensor unit and immersed in the wort.
The explanation about this device is nonsense! How does it measure the specific gravity of the wort if there is no sensor in the wort?
P B on Oct 17, 2015
BEST ANSWER: This device measures the gravity buy suspending a "torpedo" in the liquid from the sensor unit that is outside on the fermenting vessel.
How much clearance above the fermenter will you need for this, also with an airlock?
Joe D on Oct 17, 2015
BEST ANSWER: The device itself is 4" tall

and about 3.5" of it stick out above your fermentor. The height with an airlock attached is 7.75" - 8"
Would you please list all data points delivered?
L E on Oct 16, 2015
BEST ANSWER: The BeerBug takes readings every 20 minutes and uploads them to the cloud. You can also put it into "High Activity" mode by pressing the button. Then it will constantly be uploading data for 5 minutes before switching back to its default cycle. The data is then viewable on the BeerBug app in your profile. It will begin monitoring from the time you start a new brew until you tell it the brew is "finished" in the app.
My brewing setup consists of a glass fermenter, airlock, and a heating element wrapped around the fermenter. The heating element is controlled by a thermowell which passes through the stopper. Using you device would require one more port on the stopper. Is this possible?
A L on Oct 16, 2015
BEST ANSWER: The beer bug is inserted wherever your airlock would be inserted..then you put the airlock on the beer bug. So if you have a port that uses the airlock

just use that same hole.
