I’ve never done keg hops, but I’ve gotten hop burn from poorly “filtered”/kegged NEIPA’s. It usually dies down for me after a week or so in the keg, and can be mitigated by sort of rustling the keg and immediately pouring what gets rustled up by the dip tube. This will usually clear out 90+% of the hop matter that can lead to excessive spiciness/hop burn/astringency.


This is it exactly. It’s a spiciness. And I did have issues with filtering, lots of hop material going in the keg that shouldn’t have. Even from the boil into the fermenter.

I should have those issues addressed for next time so we will see, but I think you nailed it.

Figured I would show y'all some data points from my currently fermenting NEIPA using the Tilt Hydrometer and Thermometer.

This graph starts 36 hours in and continues until around 5:30 this morning. You can see a couple of spikes on the SG probably due to the fermentation turbulence or possibly krausen. So far, it is working just as I intended: a tool to let me know when fermentation is finished and a confirmation that my temperature controller working properly. Will try and give you guys an update after the dry hop tonight.

That is one of the coolest gadgets for homebrewing. Have you compared it for accuracy against a hydrometer?

Mine should be here today.

This is exactly why I wanted it. Hopefully I can get a signal through the conical.

It was within .002 with corrected refractometer calculation at pitch. I was trying to avoid taking samples, but I may for posterity.

I have SS brew buckets, I am getting readings through the fermenter, through the chest freezer and through 2 layers of sheetrock about 15 ft. away. YMMV

Thanks. Hopefully my mileage wont vary too much. That's exactly what I'm hoping for. The difference is that I don't know if the conical is grounded or not. Worst case I figure I can crack open the tri-clover at the top of the conical to get a signal.

Zap, you can name it anything on the app.

For instance: 'Barry's pet gerbil' or 'Manilow's D.O.'

Good activity overnight. I should be coming close to the end of fermentation tonight so I may ramp up and see if I can squeeze a bit more out of it. I hate seeing the fluctuation of temperature on the chart but it is not too bad. Normally if I brew a single 5 gallon batch, I will put a keg or my other fermenter full of sanitized water beside it to take up the chest freezer dead space and control temp swings. I was planning on brewing another batch so I did not fill the dead space this time. One point I found interesting on the graph this morning was the dive just after dry hop. There was still some activity in the blow off tube this morning so there is still a little turbulence/krausen influence on the data points after dry hop. It does seem to be leveling out this morning.

ETA Mountain Tiger, when I got home from work I had a full hour where the Tilt was out of range of the spot from which I was logging data. I moved it about a foot closer and it corrected. My mileage varied

I can get a signal with the conical lid on if I'm standing within a few feet of it. I didn't have the clamp on so hopefully that doesn't affect things.

Have you ever had a problem with bubbles affecting the reading? I put a few gallons of water in last night, dropped the Tilt in and it was reading 1.001-1.002. This morning I checked it and it was 1.022. So I opened it up and there were a lot of bubbles on the outside of the device. I knocked those off and it went back to reading 1.001.

I have definitely had interference during fermentation but I was never worried about the accuracy of the readings, just when they begin to level off.

Admittedly, I did not test it in water for a long period of time. I had the initial reading of 1.001 for a good 15 minutes and that was enough for me.

Thanks. It worried me a little because there are definitely going to be a lot of bubbles during fermentation. Yours seems to be working just fine so I'm not that concerned. We'll see I guess.

Here's what I'm thinking of doing. I have an ancient Android tablet that I don't really use anymore. If it will run their software, I'll just leave it on top of the conical gathering data. If the Tilt app won't run on it, then I'll just use a Raspberry Pi.

Right now I am using an iPad but I am going to dig up an old iPhone for any future brews. Compact and uses less power. Not sure how the range will be vs. the iPad so I may have to prop it on top of the chest freezer instead of in the living area of my home. A big drawback unless you have a raspberry pi is that in order to log data points using the app, the app must be opened in the foreground and the device must be plugged in.

so is the data tracked on the device or in the tilt so you dont have to have your phone hooked up the whole time?

answerd my question. That sucks.

I wonder if it can be tracked via CraftbeerPi ETA: looks like it can!.

I keep talking myself out of any Pi's.

Alright one more graph. Turns out I had left the app in the background while at work yesterday but the SG was steady at 1.024 when I left and 1.024 when I returned so nothing major there. I did ramp up to 68 and it is pretty cool to see the last bit of fermentation occurring on the right side of the graph. Wondering if I should move to 70. It is WLP008 so I think it can handle the rise.

why? im planning a basic electrical panel build controlled by a pi. idk how long it is gonna take but im gonna try.

At least from a 2 tap keezer standpoint, the cost of the flowmeters, etc. for the raspberry pint build is a little much and would really only be cool when entertaining (or knowing when wife snags a taste).

As for fermentation controls, it is definitely something I have been researching. IIRC, Weskarl's died at an inopportune time and he went back to an inkbird. That makes me nervous.
