DME Calculator
Calculate the amount of Dry Malt Extract needed for your yeast starter based on target gravity and volume.
Calculate DME for yeast starter gravity and volume
Use the DME calculator to estimate how much dry malt extract you need for a yeast starter at a selected starter volume and gravity.
Example starter DME calculation
For a 1 liter starter around 1.037 gravity, enter the starter volume and target gravity to estimate the amount of DME needed for the starter wort.
- Choose a starter gravity appropriate for yeast growth.
- Enter starter volume in liters or gallons.
- Weigh the calculated DME before boiling and chilling the starter wort.
Watch for: Starter wort is usually kept moderate in gravity so yeast can grow without unnecessary stress.
Frequently asked questions
What is DME used for in a starter?
Dry malt extract provides fermentable wort for yeast growth before pitching into the full batch.
What starter gravity should I use?
Many brewers target a moderate starter gravity near 1.035-1.040.
Can I use LME instead?
Yes, but the amount differs. Use the DME to LME calculator when substituting extract types.
How does this connect to pitch rate?
Use the pitch-rate calculator to decide starter size, then use this calculator to prepare the starter wort.
