What is your approach to degas beer for a Gravity reading?

[The Brew Mentor]

View attachment 17421 Ultimately my degassing gave me comfort that I'm close to enough to terminal gravity for government work. Target for this batch was 1.038 for OG, and 1.012 for FG. Actual OG was 1.035 and FG was 1.014. Instead of ABV slightly above 3%, it’s slightly below. Attenuation was super low at 60% vs. expected of 75%, perhaps explained by an initial temperature spike or …? Cold crashing now.

I’m calling this English Mild - “Quite. Quite. Indubitably Mild.” Best uttered while lighting/puffing a pipe.

And I was thinking just a typical high flocking English yeast. They can drop like a rock early on and if not roused, sometimes don't finish. Another characteristic from that would be diacetal and acceptable in low amounts in the English styles.
Cheers

Yeah in regards to low attenuation I wouldnt expect a temp rise to cause it unless it went beyond the yeasts high temp range like 30c
Maybe more of a vitality thing maybe alot of old yeast cells at pitch or low nutrient or Oxygen wort content.

Good points. Yeast was a recent purchase, but I don’t add nutrient and just shake the keg/fermenter for oxygenation. Might need to revisit that.

It may also be a one off.
Keep an eye on it and address it if it keeps on happening.

Putting the beer into an ultrasonic cleaner works great for degassing. Still takes a while but at least it's automatic.

I just measured gravity on batch that has fermented under pressure, 1028, wait what?
Found this thread through a search on the GOOGS.
Poured back and forth between two glasses a number of times, gave the hydrometer a good spin and voila, 1014 as expected!
Then, wait for it, I giggled, out loud!
Or is that jiggled, whatever

Depends on your anatomy, perhaps?

Am I the only one that just pulls the sample the when I get home and checks it in the morning? put a breathable cover on it and the co2 will escape overnight.

I have to admit to hardly ever doing an FG sample.
But when I do, I take a reading with refractometer and another reading the next day.

I think so I've never had the patience to do this smart move man.

Whatever the Tilt says is close enough.

Since the sample is getting discarded, what if one microwaved it to heat it up below 80 c and let cool to take the reading?

Takes time, particularly cool-down. Evaporation could be significant. Plus, I generally taste it too. It should work though, with some accommodations (cover the hot sample, put it in the fridge, for example)

Shake and wait is my method. After several minutes the bubbles are gone.

 

[StarvinMarvin]

Thank for the advice, I tasted first, only heated for 55 seconds, no vapor or steam, used a kitchen whisk to finish degassing and by time I finished shoveling snow it was cool enough. next sample will try the shake/whisk wait method.

Snow! WTF!
I'm hoping not to see any more of that this spring!

1 Degree Celsius sy 930 pm and light rain
Going take a sample tomorrow anticipating 90% fermented gravity about 1.021

So wait a tick... Let's just say my beer was carbed to about 4 psi at 35F (which appears to be almost 2 volumes?) and I spun the hydrometer but did not de-gas the beer at all. Did I get an accurate reading?

it very much depends. the bubbles tend to stick to the glass/plastic and "float" it.

I generally take 350ml samples. I used to put my hand over the graduated cylinder and shake the living shit out of it, let it sit, then shake again.

I have heard folks talk about for pouring it between containers up to 30 times to degas it in lab settings.

I use a milk frother to stir it. I pull the samples and stir them as i am walking over to my sink area, let them rest till they clear up and warm up then stir them again for a min. and take my sample. i often pour the sample in the tube and walk away for a min or two.

Agree. That quote is 4 years old, and the answer was No, I did not get an accurate reading. Now I shake and wait.

lol ya i saw that after i responded...i could report the post? can we report it as a zombie thread?

I don’t mess with zombies.
