Help with a starter for larger batches
Posted: Mon Jun 18, 2018 11:13 am
Hi.
I'm looking for advice on making a started for a 30G ~6.9% beer from a washed and saved yeast that is about 3-4 months old.
I have successfully washed yeast and reused it in a 1.5L starter for a 5G 5% beer before so I kinda sorta know what I'm doing but I'm just a bit worried about under pitching 30 gallons of beer.
Specifically, I'm wondering how many of my washed samples to start with. I have 4. 2 each saved from a 5G batch. I'm thinking I can start from 1 and build from there?
How old is too old for saved yeast?
How do I estimate starting cells? The online calculators seem geared towards liquid yeast packs and let me enter a packaging date. Should I assume one of my washed and saved containers is equal to a package of store bought liquid yeast (of similar age)?
What sort of containers do you guys use? I can start in my usual 2L flask that fits on my stir plate but after that it seems like it will outgrow the container quickly after stepping it up. Can I use a 5G carboy?
