Help with single starter for double batch brewday.

[Rolly]

I'm going to do a double brewsession next week. 5 gallons of 1.085 barleywine and 5 gallons of 1.062 oatmeal brown ale.

I have 3 vials of wlp007 english dry ale. I also have 1 2000mL flask and a stirplate. I'm confused as to how I should pitch the correct amounts in each carboy. Should I make one starter with all three vials, and pour 2/3 of it into the barleywine and 1/3 into the brown ale? Or make the first starter a for the barleywine a few days earlier with two vials, crash and decant to another container then make the starter for the brown?

I just wanna make sure I pitch the correct amounts in each carboy, and mrmalty is confusing me right now.

Next time save the money and make a starter from one vial. Yeast is my biggest cost at 7 bucks a vial.

Anyway, I'd make one 2000ml starter from one vial (plenty of cell count for that). I'd boil 2000ml of water with 1 to 1.5 cup of DME for 10 minutes (shooting for a 1.040 OG starter). It will boil down to about 1800ml. Make the starter about 36 hours prior to brewing. I'd pitch a little over half (maybe 2/3s) into the Barleywine and the rest into the Brown Ale. WLP007 is a beast and should take off very quickly. My 1000ml starter looks like cottage cheese in beer. My starter finished in less than 24 hours.

Or you could use one vial to make a 2000ml starter for the Barleywine and pitch the other two vials into the brown. Either way you will have plenty of cell count for both batches.
