Question with Starter.

[BrewMeister Jeff]

I am buying a propagator pack for my brew on Sunday.

I am brewing 11 gallons - Do I need to buy 1 or 2 packages? I plan on making a starter but only have 1000ml beakers.

What's your OG? Do you have a stir plate?

Btw, a propagator with a 2L starter will equal an activator pack (100 billion cells)

Have you got any 1 gallon jugs? A prop pack will need a fair bit of buildup to do 11 gallons.

[BrewMeister Jeff]

OG will be 1.051 - Yes I have a stir plate.

So I could forgo the starters and just by the activators?

[davebl]

You need 393 Billion cells.... SO:

1 Activator into a 3.75L starter (or 2 x 2L starter... 1L starters just don't have enough food to really build cell counts) with a stir plate

OR 2 activators into a single 1.5L starter

and these counts are for the "brewery standard" .5 billion cells x ml of wort x degree plato.
