Time needed: 3 hours and 15 minutes.

  1. Strike Water

    Add 6.5 gallons of Reverse Osmosis Water to your kettle. If you have a TDS meter, make sure your RO system is functioning properly and is reading 0.0 TDS. Raise your strike water to 122 ºF.

  2. Add Replicator to Strike Water

    Once your kettle has reached 122ºF, take your Asheville Replicator, shake it well, pour it in to your kettle, and stir until completely combined. Your water will likely become cloudy. This is normal!

  3. Mash In

    Gradually add in the Flaked Rice, American Pale 2 Row and Pilsner Malt. Stir continuously to avoid dough balls.

  4. Protein Rest

    Allow the temperature to rise back to 122ºF. Hold at this temperature for 15 minutes.

  5. Saccharification Rest

    Raise the temperature to 145ºF and hold for 120 minutes. If you have the ability to recirculate, do this now. If not, just stir the kettle every 15 minutes or so.

  6. Mash Out

    Turn on the heat, and allow the temperature to rise to 168ºF. Once you’ve reached this temperature, your mash is complete.

  7. Boil (60 min total)

    Bring your wort to a boil and add 0.50 oz of Crystal hops. Allow to boil for 55 minutes.

  8. Boil Continued (60 min total)

    When there is only 5 minutes left in the boil, add the remaining 0.50 oz of Crystal hops and the WLN1000.

  9. Chill and Ferment

    Chill your wort as quickly as possible. Once it has reached 48-55ºF, separate the wort, then pitch both packs of WLP940 Mexican Lager Yeast. Since your’re not pitching at Ale temperatures, it is critical to double the pitch rate to achieve the healthiest fermentation possible. If you desire a Gluten Reduced beer, add the WLE4000 Clarity Ferm when you’re pitching the yeast.
