Large yeast starter for a group brew of ale (yielding 35G of wort)

[clark123456]

What is the best way to provide enough yeast for a 35G batch of ale (1.056 OG)? I've looked at Mr. Malty and Jamil's calculator suggests I need around 1400 billion cells. The calculator also suggests to use 6 vials/packs into roughly 7 liters of starter. I have a stir plate that is capable of doing 5G starters. Should I:

• Step up one vial/pack multiple times?
• Pitch 6 vials into the 5G starter directly?
• Do something else? If so, what?

Do you have enough time to brew a 5G batch of small (low OG) beer? That's what I'd do and use the yeast cake. Something low gravity, low hopped would be best.

I think 2 vials into a 5 gallon stirred starter will work well. Roughly 11 million cells per ml.

Oh yes, there's plenty of time to do whatever is necessary. The brew isn't until May 5th.

Thanks for the input.
