You will basically be performing a double mash, one for the cereal and the other for the rest of the grist. To gelatinize the cereal grains:
First mill your adjuncts, either rice or corn, to a very fine grist (think grits). For rice it's probably better to use a coffee mill than a grain mill. To the milled adjunct you will be adding about 10-20% of the total malted barley in the recipe. The enzymes in this addition will help break down the starches. It's best to use high-enzyme malts such as domestic 6-row or domestic 2-row because the adjuncts will be diluting the total enzyme concentrations of your mash. British ale malts just don't have enough enzymes to produce acceptable American lagers and aren't recommended.
Next, add heated brewing water at a ratio of 2-3 quarts per pound (4-6 liters per kilogram) to reach a mash temperature of about 158° F (70° C) which represents a temperature that will mash both corn and rice, and hold it there for about 15 minutes. If you are using adjuncts other than corn or rice, or want to be more exact, here are the gelatinization temperatures of the usual adjuncts you will want to use (choose your own mash temperature):
Barley 140-150° F (60-65° C)
Wheat 136-147° F (58-64° C)
Rye 135-158° F (57-70° C)
Oats 127-138° F (53-59° C)
Corn (Maize) 143-165°F (62-74° C)
Rice 154-172° F (68-78° C)
Now, bring the mash up to a gentle boil and boil for about 20 minutes or up to 30 minutes (until the mash breaks down and coats the back of your spoon) stirring constantly so the mash doesn't scorch.
Now the question is, how to add the cereal back to the main mash. There are several options here. Normally when doing a double mash, you would start your main mash and be at the protein rest when the cereal is through. Adding the cereal and more hot water should get the main mash up to the saccharification rest temperature. You will have to use the decoction formulas to determine the amount of water to add or just wing it and stop adding water when you reach your target temp. Or, you can do both mashes in the main mash tun. First do your cereal mash. Add cool water to cool the cereal mash to the first temperature rest (if doing a multiple-step infusion mash or decoction) or to ambient temperature, then add the rest of your grist and water to bring the mash up to saccharification rest temperature. Evidently some experimentation or adjustments on the fly will be necessary for the first few cereal mashes you do.
If you don't think the cereal mash is much fun, do what I do, buy flaked grains that are pre-gelatinized and don't require the separate cereal mash.

Need some help here from singapore.
In singapore there is no flake rice or minute rice. Is there any substitute for it?

It was a royal pain in the butt. But saying that I did another brew with potatoes the other day and just boiled the crap out of them and dumped the spuds and water right into my mash. I tried a bottle of it and it was pretty good
Nope just toss them in your mash if they are flaked already. Only time you need a cereal mash is if you are using raw grains. I have found it much easier to use instant rice and instant grits when I make this recipe and it is much cheaper than buying flaked stuff from a LHBS.
But I will say rice hulls are your friend to avoid stuck sparges whenever using adjunct grain. I know some do not use it but getting caught by the wife with your drain tube in your mouth blowing backwards trying to unclog a stuck sparge sucks.
Another one on the list for summer.
You better get on it! Summer beers need to be brewed in spring!![]()

Just so you know there is no reason to use rice that I know of except to raise sugar level for alcohol without changing the beer . The rice adds the sugar and does not mess with mouth feel or taste without thinning it out like corn or table sugar . Use generic minute rice . It is a couple bucks for about 2 pounds I think it is . A whole lot cheaper than minute rice . Do not cook the minute rice . It has already been cooked and only needs to be mashed .

edit
Grits may add in some flavor I would think since they are corn and actually have a bit of flavor unlike rice . Grits are usually alkali treated so they have some flavor from that process . Other than that they are nothing but ground corn
that is my two cents ...your mileage may differ
shadyj said:So I have some East Coast Ale Yeast that I need to use up in the fridge. Would this work for this beer? I see that WL rates it 2/4 for american cream ales but if the consensus it that it will be fine then I'll start brewing away.
Hi. I am going to make this shortly. I will be fermenting in the 62 f range because i will be fermenting it next to a cali common. Would you recommend Nottingham or safeale us 05 or something else besides kolsch...that stuff won't floc.
Bump
Would it hurt here if I evened up the rice and corn? How would this affect the final beer? Too dry? Thanks
