Hi I have never been able to completely work out how to use the Mr Malty Pitching Rate Calculator in terms of my yeast starter techniques. Essentially I only make one size starter so Mr Malty is irrelevant, but I am interested in how my starters compare.
Firstly I make a starter for all my yeast, the only time I do not make a starter is when I pitch directly onto the yeast cake of a just racked beer. Anyway I use Wyeast as my preferred yeast. (have used pro-culture just the once).
My starters are made in a 2.5-3L flagon (can't remember the exact volume). If I am using a new Wyeast pack I will added 1.5-2L of wort (10g/100mL DME-Water) to make the starter. When I pitch the starter I reserve some yeast for the next - as pretty much everyone does. Now I used to reserve the yeast in stubbies but for a while now have been using the small test tubes as in this thread http://www.aussiehomebrewer.com/forum//ind...\&st=0
These test tubes take up a lot less room in the fridge. Once the yeast has settled out in the test tube, only the bottom 1/4 - 1/3 is yeast slurry. Now this is a very small amount of yeast. I will use 1 test tube to make my next starter.
I have never noticed the effects of under pitching in my beers (although it may be be there), but recently altered my yeast starter regime to account for the small initial yeast count. I will build the starter up over three to four phases starting at about 10g/100ml - adding say 30g/600ml, 130g/1300ml total 2L starter ( I used to pitch the test tube directly into a 1.5-2l starter). I try to add the next phase when I think the yeast has gone through each growth stage.
Anyway my question is how do I correctly calculate my yeast count and how could I use Mr Malty to calculate it?
