What do you mean by harvesting from your starter? Most of the time we pitch our entire starters in.
Are you referring to growing up yeast purely for the purpose of building up your "inventory" and not necessarily brewing right away?
I do it all the time, mostly bottle harvesting though. If I get an interesting beer, and suddenly decide to harvest the yeast but have no use for it now,I do exactly that.
Did it awhile ago with some maudite yeast.
You can obviously build up a huger starter than you need, and jar or slant the rest.

I gotta tell ya, just between us girls, that Revvy is HOT. Very tall, gorgeous grey hair and a terrific smile. He's very good looking in person, with a charismatic personality... he drives like a ****ing maniac! - YooperBrew
