Odd Tilt fermentation chart - anyone seen this before?

[beernutz]

I am running a Tilt for the first time on an India Pale Lager. Last night I was receiving updates to the google sheet when they stopped for 2 hours 45 minutes. When I started receiving updates again 8 hours ago the SG jumped up about 5 points and has stayed there, bouncing between 17 and 18. It looks odd so I was wondering if this had happened to others.

CO2 bubbles stuck to the Tilt can give high SG readings. In my experience, the bubbles eventually dissipate, and the SG readings go back to where they should be. The bubbles are usually around during the earlier stages of fermentation, which you still appear to be in.

Brew on

Thanks, that makes sense so I'll avoid my natural inclination to "do something" and wait it out.

I brewed on Friday and had an OG of 1.048 but I didn't get logging to the Google sheet working until 28 hours later so some activity isn't shown. Early this morning SG hit a low reading of 1.011 before this odd jump back up to 1.017/1.018.

Mine jumps around when I cold crash, but usually not before. I don't see a big temp change during your "jump"

I just emailed the manufacture for the same reasons. I wrote: I made a brew last week and used the Tilt for the first time. I am getting random fermentation numbers where it starts at 1043-1.044 then rapidly lowers to 1.004. Then within a day or so increases to1.007. Now I see where it has dropped to .993 and went back up to 1.006 and is now 1.003. It also shows an apparent attenuation of 115.73%

This can't be normal and there is no mentioned of this in your FAQ. Do I have a bad unit?

Could it be that the tilt got stuck against the side, went vertical enough to turn off, and then slipped off whatever it was stuck against and started reporting again?

@Hopsimus , I think you are correct that maybe it got stuck on something (cooling coil, side) which caused the up / down gravity numbers. Do not believe it ever turned off.

This was the first time using it. It will be interesting to see how it works in a few weeks.

Thanks for responding!
