I have 375ml of 2206 slurry from 9/24/14. I want to brew a dunkel 1.056 OG on Wednesday.
Since I’ve waited so late to make the starter my only option is to make it about 12 hours before I brew and pitch the whole starter at high krauesen.
With a one step 2L starter I would need 3 new packs of yeast according to mrmalty.
MrMalty says my slurry is only 10% viable. At the highest concentration of yeast it says I need 1100ml of slurry.
Yeastcalc using the middle of the road concentration of yeast and mid range trub says I need 230ml of ‘washed yeast.’ Yeast calc doesn’t account for the age of the ‘washed yeast?’
So I’m thinking of making a 2.5L starter and pitching the 375ml of slurry to it then pitching the starter at high K.
