The process for performing the cereal mash phase is as follows:

Mill or grind your cereal adjuncts down into a fine grist – ideally smaller than your milled barley grains. Add about 20% of your total malted barley grains (i.e. Pale or Pilsner malt) to the cereal adjuncts. This malted barley will provide the enzymes needed to aid in converting and breaking down the sugars, as many cereal adjuncts don’t have sufficient enzymes by themselves.
Next add hot water at the rate of 2-3 quarts/lb (4-6 l/kg) to produce a fairly thin mash. This is a simple infusion, but you want to target the gelatinizing temperature ranges listed above depending on your adjunct. So if you are working with raw oats, for example, you need to be in the 127-138 F (53-59 C) range. Hold the gelatinization temperature ranfe for 20 minutes.
Slowly raise the temperature of the cereal mash up to a gentle boil and hold it for 20-30 minutes. As you do this the mash will go from a grainy mixture to a pretty sloppy gelatin mess that should coat the back of your spoon. When you reach the liquid goo phase, the cereal mash is good to go!
Finally add the gooey mixture into your main mash. If you are working directly with the hot liquid, you can often use a decoction calculator to figure out how high your starting mash temperature needs to be when adding the boiling cereal mash to hit your desired sugar conversion range – which is usually between 148-156 F (64-66 C). The other option is to use cold water to bring your cereal mash down to the target temperature before adding it to the main mash. After that you continue your conversion phase and sparge as you would with any regular all grain mash.



Mill the grains (including the flaked grains, but excluding the rice hulls). Mix the rice hulls into the grain post milling and dough-in targeting a mash of around 1.5 quarts of water to one pound of grain (a liquor-to-grist ratio of about 3:1 by weight) and a temperature of 122 °F (50 °C). Hold the mash at 122 °F (50 °C) for 15 minutes then raise the temperature over the next 15 minutes to 154 °F (68 °C). Hold until conversion is complete, about 60 to 90 minutes. Raise the temperature to mash out at 168 °F (76 °C). Sparge slowly with 170 °F (77 °C) water, collecting wort until the pre-boil kettle volume is around 6.5 gallons (25 L) and the gravity is 1.039 (9.7 °P).

The total wort boil time is 90 minutes, which helps reduce the SMM present in the lightly-kilned Pilsner malt and results in less DMS in the beer. Add the bittering hops with 60 minutes remaining and the spices with five minutes left in the boil. Do not bother with Irish moss or other kettle finings. Chill the wort rapidly to 68 °F (20 °C), let the break material settle, rack to the fermenter and aerate thoroughly.

Pitch ten grams of properly rehydrated dry yeast or use two liquid yeast packages. Alternatively make a 2 qt. (2 L) starter using one package of liquid yeast. Begin fermentation at 68 °F (20 °C) slowly raising temperature to 72 °F (22 °C) by the last one-third of fermentation. When finished, carbonate the beer to approximately 2.5 to 3 volumes of CO2.
