EWildcat7 Posted June 17, 2019 Author Share Posted June 17, 2019 the difference in gravity readings over the last 2 days has taught me a valuable lesson about using the hydrometer to know when fermentation is complete! since I am in a minor time crunch (I am going out of town) and need to get the beer bottled before a week from tonight, I will be taking gravity readings every day until I see it is stable. Hopefully it is done by Thursday, I can cold crash until Sunday and then bottle 2 Link to comment Share on other sites More sharing options...
Otto Von Blotto Posted June 17, 2019 Share Posted June 17, 2019 If you warm it up a bit it might finish off quicker. 1 Link to comment Share on other sites More sharing options...

Otto Von Blotto Posted June 17, 2019 Share Posted June 17, 2019 Cool. What was the second SG reading? Also, what are the ingredients and batch volume? Could probably estimate the FG based off that info Link to comment Share on other sites More sharing options...

I am going to take another reading tonight (Tuesday) I followed the Bilby Chocolate Porter recipe, so the ingredients were: - 1.3 Kg Mr. Beer Winter Dark Ale - Mr. Beer unhopped malt extract - smooth - 100 g midnight wheat grains - 1 tbsp cocoa powder - lallemand nottingham yeast Link to comment Share on other sites More sharing options...

Otto Von Blotto Posted June 17, 2019 Share Posted June 17, 2019 I wouldn't expect it would go much under 1.013, and very surprised if it went under 1.010. 1 Link to comment Share on other sites More sharing options...

How long are you out of town for? If it isn't ready in time you may be able to just cold crash it until you get back. The other option would be to bottle it without a cold crash.

I am gone for 3 weeks, but I don't leave until Tuesday morning, so I still have a few days. I figure that I will take a reading tomorrow (Wed) and, if it is the same as tonight, start the cold crash on Thu morning and bottle on Sunday. This plan gives me an extra day just in case the reading is different tomorrow. Link to comment Share on other sites More sharing options...
Otto Von Blotto Posted June 18, 2019 Share Posted June 18, 2019 Ok yeah 3 weeks is probably a bit long to leave it sitting even if it is chilled down. I'm sure it'll be ready in time though, doesn't sound like it has far to go. Link to comment Share on other sites More sharing options...
Lab Cat Posted June 19, 2019 Share Posted June 19, 2019 If you are short on time and want to be sure it's done, skip the crash, just bottle it. Link to comment Share on other sites More sharing options...

EWildcat7 Posted June 19, 2019 Author Share Posted June 19, 2019 (edited) 1.011 this evening - same as yesterday, so I will give it another 12 hours and start the cold crash tomorrow morning However, I saw something very interesting...when I took the gravity reading tonight (1.011), I got distracted and didn't take the hydrometer out of the tube. When I looked at it after a while, it had risen to 1.200! I took it out and re-inserted it and it read 1.011 again. Any ideas?

Is it a glass cylinder and glass hydrometer... or a plastic tube and hydro? Is everything completely on the level and you took the same reading in exactly the same place with exactly the same temp? How long did you wait for the hydro to settle when you took the first reading... bubbles? These things are pretty finicky I think...

I waited for the bubbles to subside before inserting the hydrometer. It seemed like the hydrometer rose over time Link to comment Share on other sites More sharing options...
Pezzza Posted June 19, 2019 Share Posted June 19, 2019 Velly intellesting! To say the least. My plazzi hydro was a bit troublesome... and had quite a lean on the plazzi cylinder which made measurement more challenging. As a scientist I would suggest that you need to take 5 replicates and observe the Specific Gravity Measurements in the cylinder for each rep in 30 second intervals over a half an hour period per sample, and then utilize MATLAB to provide some statistical analysis to determine the standard deviation and........… only joking..... Dunno… suspect that the 1.011 on initial, then on post-rise... might be where things are at... I would go with that. And the festive rise up to 1.020 might be a collective adherence of bubbles to the hydro bulb? Or an Alien was momentarily tele-transported in an inadvertent tear in the time-space continuum mesh into the Hydro Bulb which caused a negative-gravity vortex effective enough to allow the bulb to float 9 points free? 2 Link to comment Share on other sites More sharing options...

I feel pretty confident in the 1.011. It matches last night, so I am considering this done and will start the cold crash in the morning Link to comment Share on other sites More sharing options...

And what Volume - 12L? Plugging into Iain's Spready... says 1.011 is a little high... but not far off... Have you used this? Wildcat.xls Link to comment Share on other sites More sharing options...
Otto Von Blotto Posted June 19, 2019 Share Posted June 19, 2019 Probably just bubbles pushing it up. They take a while to completely stop unless the gas is forced out. The SG can't rise unless more sugar is added. 1 Link to comment Share on other sites More sharing options...

I'd probably go with RStudio for a statistical analysis. MATLAB would be good for a nice real-time 3D plot of density, bubble formation, and temperature which could then be integrated to find the B3R factor (Bearded Burbler Brew Readiness factor). 1 Link to comment Share on other sites More sharing options...
Navigator Posted June 19, 2019 Share Posted June 19, 2019 (edited) I dont have a temperature controlled fridge of any sorts, I have two milk crates in a room that my 2 Fv's sit on and my wort seems to sit around 21 c, So do you guys n gulls think I'm better off sticking to ales and ipa's ..?
