    General rule is 100g/L. Add your DME then add your water to bring it to the volume you want.

    I suggest you go to http://www.yeastcalc.com You need a certain number of cells derived in 1.040 wort. This will solve the problem for you...

    DME is about 44 ppg, and LME is about 37 ppg so you will need about 120 grams LME for a 1L starter, so 240 grams for a 2L starter. Just add the extract first then fill with water till you have 2L.

    But even if he uses a fresh vial for 5 gallons of 1.120 wort (assumption for 12% beer) he needs ~400 billion cells. A 2L starter with intermittent shaking gives ~250 million cells. He's way under pitching and asking a question that indicates he doesn't understand what he's actually doing...

    Yea. This is another option for figuring out pitching rates: http://www.mrmalty.com/calc/calc.html

    Edit: Also that site is awesome.

    Really? Since the extract adds volume I measure the water first. I'm sure that it's no big deal though.

    The 3 things I like best:

    1: Easy step starters
    2: Fully customizable (including how many cells after brew - label your yeast container :slight_smile:
    3: The starter wort calculator on the lefty hand size.

    Things I don't like:
    1: Won't work on iPhone/iPad

    That is all. :slight_smile:
