G'day,
I've read most of the threads on here on the topic, but I just need some final advice.
I plan on splitting 125ml smack packs in 4, so let's say around 30ml. For my theory, I have used a 6 month age (10% viability).
That leaves me with 2.5b viable cells.
Now, reading around I've concluded that it's a safe bet to increase steps by 4xvolume for lagers and I assume this is based on the slurry volume not the cell count (please stop me here if I'm wrong!).
So for the above scenario and a target final population of 450b, would I be on track doing the following:
1. 120ml
2. 480ml
3. 1900ml
4. 4500ml
= 457b cells.
I have a 1L and 5L flask, so my plan would be to accumulate the first 2 steps in the 1L, then pour the lot into the 1900ml starter in the 5L, then once that is ready, chill, decant, and add the final 4.5L, let it ferment to high krausen and then pitch the lot into the awaiting beer.
Any criticisms/suggestions most appreciated!
Cheers,
