Overview:  This is my standard oatmeal stout recipe, but this time it will be batch sparged.  I'm planning to submit this for auction at the "Men who Cook" dinner for the school.

Ingredients:
7 lb. Pilsner
1 lb. Munich
1.5 lb. 40L Crystal
1 lb. Flaked Oats
.75 lb. Roasted Barley
.5 lb. Chocolate
.5 lb. Carapils
.25 lb. Flaked Barley

1 oz Northern Brewer @ 60 min
.25 oz Styrian @ 15 min
.5 oz Styrian @ secondary
.5 tsp Irish Moss @ 15 min (stock)
Wyeast 1084 Irish Ale
-----
Plan is to bottle...

Mash:
Total grain bill = 12.5 lb
Mash water @ 1.25 qt/lb = 3.5 gallons (160 deg F.)
Assumed grain absorption @ 0.1 gal/lb. = 1.25 gal.
Water after grain absorption = 2.25 gal
Runnings = 3.25 gal * 2
Additional strike water = ~1 gal (boiling - try to reach 165 deg. F mashout)
Second water addition = 3.25 gal @ 185 deg F.

Procedure:
1. Heat 3.5 gallons to 160 deg F. add to grain in cooler and mash for 60 min.
2. Boil 1 gallons, add to mash, stir and rest 15 minutes
3. Sparge and recirculate slowly until runnings are clear.
4. Open up the flood gates into the brew kettle.
5. When mashtun is empty, stir in additional 3.25 gallons @ 185 deg F. and let set for 10 minutes
6. Repeat steps 3 and 4.
7. Bring to boiling.
8. When boiling, add 1 oz hops.
9. After 45 minutes, add .25 oz hops and Irish Moss, add chiller
10. After 60 minutes, remove from heat and chill rapidly.
11. Whirlpool and let set for 15 minutes.
12. Transfer to primary, pitch yeast, and stir.
13. When fermentation stops (3-5 days), transfer to secondary with hop tea
    13.1. Boil 2 cups of water in 2 separate pans (1 cup in each)
    13.2. Place .5 oz hops in a nylon bag with the top open.
    13.3. Pour contents of bowls over the hops.
14. After 1-2 weeks, transfer to keg.
15. Cool overnight, carbonate to 2.6 gravities.

Notes:
2008-02-29 - Everything went pretty well.  Used the new mashtun constructed from a cooler and some CPVC pipe with brass fittings.  I have a slow leak somewhere in the works that I need to figure out, but if I can find a 2.5" - 3.0" nipple, I think I get rid of that.

The only problem during the boil was my initial hop addition I had a massive boil over.  I added about .3 oz. more hops to try to compensate, but the bitterness might be lower due to less hops getting into the boil.  Hopefully the style will hide some of that.
