I have just built myself a tight arse stir plate using a couple of those 'rattlesnake egg' type magnets that I think Ross and several others are using. I have just pitched some yeast from a brew that is fermenting already to see how it goes growing the little buggers, but have some questions that I didn't find an answer to in my rather extensive searching of the interweb over the last few days.
I am using a 500ml pasta jar for this starter, with 250ml of 1.040 wort in it.
Do I need to be concerned about foaming? I was wondering if there is a general consensus as to whether it is necessary if the stirring vessel is over a certain ratio compared to the starter volume.
Secondly, should the stirrer be run constantly or not? My thoughts were that running it constantly might help break down the foam if it forms, but I could be very wrong on this score.
I have a slight whirlpool effect happening, am I correct in thinking that it only needs to be moving to help introduce oxygen and disperse CO2, or do you get some benefit by having the thing looking like a tornado? The magnet is set to stir nice and quietly, which is a big factor with SWMBO, along with not foaming all over the place.
Thanks for any help you can provide,
