I'm posting here as I haven't received any answer in the yeast subgroup.
How the heck one step ups a yeast starter?? I could find only partial info on how to do it for what I need, to ferment 15 gallons of cider. I'll copy/ paste the other post here. Thanks gents!
"I'd like to start creating my own yeast database and make yeast cultures on plates and slants, so I could save some $ and for the fun of it.
I'd like to make a yeast starter enough for 15 gallons cider starting from a pack/vial of White Labs W775 yeast. On the pack it says that for that amount I'd need three packs.
I was looking at http://www.brewersfriend.com/yeast-p...ter-calculator and my favourite www.brewunited.com/yeast_calculator.php that calculates how many starters I need, in my case (15 gallons), I'd need 4 starters, the last 2 being 2 L starters.
As I have only a 2 L Erlenmeyer flask available, is it possible to build a 1 L starter, cold crash it, DECANT and then use the initial yeast from the flask to create a 2nd 2L starter, a 3rd 2L starter by adding Apple juice and/or DME on top of it and so forth??? Will it reach the required number of yeast cells just using the same flask, or do I need a larger flask or separate jars to wash the yeast?
I'm lost.
When starting with a small yeast colony taken from a plate, how small should be the initial starter? 100 ml, more? I've built my own stir plate.
Thank you
