STARTER NOTES:

Yeast Pitch Rate and Starter Calculator
Pitch your yeast like the pro's do with this easy to use calculator that supports dry yeast, liquid yeast, slurry, and starters. Calculates liquid yeast viability based on manufactured date. You get to choose your desired pitch rate in million cells / milliliter of wort / degree plato. Also calculates how big of a starter to make and how much DME to add to that starter. Up to three step-ups are supported, so you can even start from a yeast slant! Two different growth curves are supported. The first comes from recently published research at Braukaiser, and the second from a study by Chris White.
Part 1: Calculate how many yeast cells are required for your batch given your desired pitch rate and if you have enough yeast.
Yeast Pitch Rate:
Units:
Sugar Scale:
Wort Gravity (OG):
1.082
(1.xxx)
Wort Volume:

(yyyy/mm/dd)
Date yeast pack was made.
Viability: Yeast is 0 days old, the viability is estimated at 100%.


Cells Available:
100 billion cells
Pitch Rate As-Is:
0.11M cells / mL / °P
Target Pitch Rate Cells:
674 billion cells
Difference:
-574 billion cells

Needs starter (see below), or more yeast.

Part 2: Make a starter if required, supports up to 3 step-ups.

DME Required:
10.9 oz, 308.1 g
Growth Rate:
