Also how long does it take for the yeast drop when cold crashing and what temperature to cold crash. Thanks Let it sit and finish fermenting etc. It only gets cold crashed after you harvest some. Temp doesn't matter much, just normal fridge temp is fine. Usually it drops in a day or two. I missed the bit about letting it warm up before pitching, I wouldn't bother, just pitch it cold. Same when pitching the harvested yeast into the next starter. Edited August 9, 2018 by Otto Von Blotto 2 Link to comment Share on other sites More sharing options...

Does it do any harm to let the plate run for the duration? Link to comment Share on other sites More sharing options...
Otto Von Blotto Posted August 9, 2018 Author Share Posted August 9, 2018 (edited) Probably not but it's of no benefit either. It only really needs to be agitated during the growing phase. You can usually tell when it stops growing, the colour of the starter gradually gets lighter and then doesn't change.

I was planning on using all of it and not harvesting any for later use as I don’t really have anything to store it in. Will I be over pitching??

Otto Von Blotto Posted August 9, 2018 Author Share Posted August 9, 2018 Depends how big you made it, but not likely to be an overpitch. If not planning to harvest any then yeah just turn off the plate after a day, give it another day or two to finish fermenting then put it in the fridge. 1 Link to comment Share on other sites More sharing options...
Beer Baron Posted August 9, 2018 Share Posted August 9, 2018 I thought I would give it a practice run. Does it matter if the flask over hangs the plate a bit? I can hear the play working but the bar just stays in one spot. If the bar does manage to get on the plate it just bounces Link to comment Share on other sites More sharing options...
Titan Posted August 9, 2018 Share Posted August 9, 2018 That's normal mine is the same. Make sure the bar is in the middle with stir plate at lowest speed then crank it up gently until you hit the desired rate. Link to comment Share on other sites More sharing options...
Otto Von Blotto Posted August 10, 2018 Author Share Posted August 10, 2018 The flask can hang over a bit, that doesn't matter. You have to get the stir bar on the magnet before starting it but as above best to start slow and gradually increase the speed. Link to comment Share on other sites More sharing options...
Beer Baron Posted August 10, 2018 Share Posted August 10, 2018 I did have it on the plate but even at slow speeds it just flicked it off. I’ll pull the stir plate apart tomorrow and check it out Link to comment Share on other sites More sharing options...
Otto Von Blotto Posted August 10, 2018 Author Share Posted August 10, 2018 Yeah, it shouldn't be throwing the stir bar. Even at high speeds. Stronger magnets? Link to comment Share on other sites More sharing options...
Titan Posted August 10, 2018 Share Posted August 10, 2018 Three things can cause this. Your missing a magnet should be 2 of them. If not 1 then one of the magnet has been fitted wrong way up. should positive up on one and negative up on the other. Stir bar is too small (or too big?), ends of stir bar should be at centre of each magnet. I'm suspecting number 3 Link to comment Share on other sites More sharing options...
joolbag Posted August 10, 2018 Share Posted August 10, 2018 I bought the exact same stirrer and use the stir bar that came with it. My mate got the same took him a couple of goes to get it sorted so it wouldn’t throw the bar. The key is to make sure it is centred, start at zero and slowly wind it up to speed. Doesn’t need to be cranking. For example i put it to approx 1 o’clock on the dial for 20mins to aerate, then dial it down to about 10 o’clock for the remaining 24 hours. Just a small dimple on the surface, no raging whirlpool and bubbles in the flask Link to comment Share on other sites More sharing options...

If you try to add the flask with the stir plate working then it throws the stir bar around the flask. As Joolbag said, sit the flask on and then turn it up.

Beer Baron Posted August 10, 2018 Share Posted August 10, 2018 Yeah I tried dropping it into the centre and you could tell the magnet stuck. I started slowly and then ramped up to around 10 o’clock and then it throws it to the side position. You can see where it is in the picture.

Otto Von Blotto Posted August 10, 2018 Author Share Posted August 10, 2018 From the looks of the picture it's thrown it completely out of the flask and onto the bench 1 Link to comment Share on other sites More sharing options...
Otto Von Blotto Posted August 10, 2018 Author Share Posted August 10, 2018 (edited) What I do with mine is tip the flask so the stir bar is to one side, place that side onto the middle of the stir plate so it grabs the bar, and then position the flask in the centre as best I can. And then turn the stir plate on. Edited August 10, 2018 by Otto Von Blotto Link to comment Share on other sites More sharing options...
Titan Posted August 10, 2018 Share Posted August 10, 2018 Well i hope this uploads but this is what should happen. Note the position of the bar at the back of the flask. Turn plate on at no speed then gently apply some revs. Magnets should pick the bar up and drag to centre. 20180810_173353.mp4 20180810_173353.mp4 1 Link to comment Share on other sites More sharing options...

Titan Posted August 10, 2018 Share Posted August 10, 2018 I also tried the same with a stir bar that is a little shorter and result was the same. 1 Link to comment Share on other sites More sharing options...
Otto Von Blotto Posted August 10, 2018 Author Share Posted August 10, 2018 You need to get it in the centre before the stir plate is turned on. I've tried that method with my stir plate just to see what would happen and it didn't work either. Link to comment Share on other sites More sharing options...
Beer Baron Posted August 15, 2018 Share Posted August 15, 2018 I got my stir plate to work but it doesn’t go really fast which is fine. I am REALLY pressed for time to brew. Do you think a small 1L starter made tomorrow and pitched into a brew on Friday midday will be okay. Thanks Link to comment Share on other sites More sharing options...
Titan Posted August 15, 2018 Share Posted August 15, 2018 Really depends on OG of the brew mate, how long will the starter be going before you pitch? pretty sure that it can ferment out in 36 hours. What was the solution to the stir plate problem? 1 Link to comment Share on other sites More sharing options...
Beer Baron Posted August 15, 2018 Share Posted August 15, 2018 OG will be 1.050. It will be around 36 hours and I figured even if it hasn’t fermented out it will be awake and ready for action. I have no idea what the deal was with the stir plate. I just pulled a few bits off and made it look like I knew what I was doing, then put it back together and it worked!! 1 Link to comment Share on other sites More sharing options...

See how it goes. Link to comment Share on other sites More sharing options...
Otto Von Blotto Posted August 15, 2018 Author Share Posted August 15, 2018 In that case just pitch the whole starter volume into the wort. It's just pitching an active starter which should actually see the fermentation kicks off sooner rather than later. 1 Link to comment Share on other sites More sharing options...
