What each ingredient does

Ground malt
Supplies enzymes and starches that convert into fermentable sugars during the hold.
Hops
Add bitterness and aroma that balance the malt's sweetness.

The step that matters

Holding the mixture between 149°F and 158°F. Malt enzymes work within this temperature range. Too hot and they are destroyed, so the starches never convert; too cool and conversion becomes very slow.
