What each ingredient does

Ground coffee
Provides the concentrated coffee flavor and aroma that defines the syrup.
Water
Extracts coffee solids and carries flavor, then reduces to concentrate the syrup.

The step that matters

Boil the mixture until it reduces to 1 pint. Reducing the liquid concentrates the coffee extract and sugar-free flavor. Stopping too early leaves it weak and watery, while over-reducing can make it thick and bitter. Reduction by boiling is what turns a dilute brew into a concentrated syrup.
