I got a message today from someone who was interested in my recipe for beer with breakfast cereal. Here it is:
For a 1 gallon batch (If you want to ramp up the size, you could do this as a partialmash, and just use extract for the balance of the fermentables. Just be sure to increase the amount of cereal. and hops, too)
2 lb 2-row barley malt
8 oz crystal malt (120L)
8 oz chocolate malt
4 cups breakfast cereal (your choice)
1 oz Willamette hops
1 pkt ale yeast
In a food processor, grind the cereal to powder. Then, in 1/2 gal of water, boil for about 10 minutes. Add to your mash vessel.
Mash the grains and cereal for 90 minutes at about 154 degrees, F. Remove the grain, and sparge, if desired.
Add 1/2 oz of the hops, and boil for 1 hour. Remove from heat, and cool in an ice water bath to 100 degrees.
Add the other 1/2 oz hops to your fermenter, and pour in your wort. top off to 1 gallon, and ferment for 2 weeks.
Bottle or keg, prime, and age for about 2 weeks.
As far as what cereal to use, it really is completely up to you. I would recommend, however, that you try to pick flavors that might work well with beer, like cinnamon, honey, or molasses. I would definitely stay away from stuff like Trix or Froot Loops.
If you try this, I'd really love to find out if it worked for you, and if you liked the result.
