- 1 packet (2 1/4 teaspoons) of ale yeast (e.g., Safale US-05, Wyeast 1098)
- Water (enough to reach a pre-boil volume of about 6.5 gallons)
Step-by-Step Brewing Process
- Mash the grains at 152°F (66°C) for 60 minutes to extract the desired sugars and flavors.

- Boil for 60 minutes, adding hops at the following times: bittering hops at the beginning of the boil, and flavor/aroma hops in the last 15 minutes.
- Cool the wort to fermentation temperature (around 68°F or 20°C) using a wort chiller or ice bath.
