Ensure the barm tub is clean and dry.
Steep the malt
Combine 1 gallon of heated water with 2 pounds of crushed malt in a pan and cover the pan.

Boil the hops
Boil 3 gallons of water in a large pan.
Add 2 ounces of fresh hops to the boiling water.
Boil for 20 minutes.

Pour the boiling hop water through a sieve into the malt mixture.

What each ingredient does
- Crushed malt
- Supplies sugars and enzymes that feed the yeast and give the barm its sweet, malty flavour.
- Fresh hops
- Adds bitterness and aroma that balance the malt's sweetness.
- Flour
- Adds starch and body, thickening the liquid into a stiff starter that yeast can live in.
