DIRECTIONS
Fill a pot with about 3 gallons (11 liters) of water. Add a Campden tablet if you are using tap water. Using a sous vide machine, heat the water to about 170°F (77°C). Place all the grains in a hops bag or paint-strainer bag. When the water temperature reaches 170°F (77°C), insert your grain bag and set the machine to 152°F (67°C) for mashing/steeping. Start your timer for 30 minutes.
After 30 minutes, turn on your stove burner and set your sous vide machine for 190°F (88°C). Monitor the temperature, and when it hits 170°F (77°C), remove the grain bag from the kettle and let it drip. Add the DME and stir as your temperature rises to boiling. At boiling, add your 30-minute hops. Boil for 30 minutes following the rest of the hops schedule. After the boil, remove the pot from the stove and chill to approximately 100°F (38°C).
Transfer the wort to your fermentor and add the 2 gallons (7.5 liters) of chilled spring water, which should bring your wort temperature down to about 70°F (21°C). Check your volume and your gravity. Add room temperature spring water to increase your volume or to hit your projected starting gravity. Pitch the yeast and ferment at 68°F (20°C) for 2 to 3 weeks. Package.
