Im doing 10 gallon batches also. Mr. Malty says we are both around 900 billion cells since i typically pitch 2 yeast packs then do double starters each with 2 steps but no stirplate. So im at the pro brewer 1.75 level on mr malty.
But 4 month old yeast would have 0% viability. At 2 months...
So like two 1 gallon starters with 2 steps on a couple stirplates? I should be well over a trillion cells. The long ferment doesnt bother me but off flavors, esters, or extended lagering would.
