Hey everyone, so I'm trying to calculate a yeast starter.
I own beersmith 2.0 and use brewersfriend.com whenever I'm not able to go on beersmith.
I'm making a 1098 OG wee heavy and am a little concerned with the differences in the cell count of my starter.
Brewers friend I selected:
Pitch rate: Pro Brewer 1.0
Yeast type: Liquid 1 pack
Mfg date: 01/14/14
This tells me I have about 33 billion cells. And I need 486 billion.
After making a 4 L starter on a stir plate it tells me I will have
608 billion cells.
Now, beersmith tells me that my cells without starter are 45.2 B and need to have 465.9 B (a little different than brewersfriend but no big deal)
But when I make a 4 L starter with the same yeast and expiration date it tells me I will have 270.9 B cells.
Now, that's a huge difference for two reasons.
1) it's a big difference from 270 to 608.
2) beersmith tells me I'm under pitching while brewersfriend tells me I'm over pitching.
I don't know who to trust or if maybe there's just something I need to configure on beersmith but can you guys give me some thoughts on this and if I'm good or not?
Info on the starter I DID make: 4 L with about 411g DME
