Yeast, probably Nottingham, the recipe recommends Wyest 1084.
I use a HERMS system and will be batch sparging
Good suggestions Dartgod:
To everyone waiting on me I'll try and get ther recipes up today that I said i would convert to Partial mash and extract w/ grains.
yup, just waiting and thirsty 
, i think i might do a partial mash for the first time with this one
Here is the final recipe, based on the last posting from BrewLuva. I have provided the recipe as an all-grain recipe. Below the recipe you will see the required mods to do this as a partial mash, or an extract with steeping grains (there is no extract only option).
BKB Community Stout
13-C Oatmeal Stout (BJCP style cat.)
Size: 5.5 gal
Efficiency: 70%
Original Gravity: 1.055 (1.048 - 1.065)
Terminal Gravity: 1.014 (1.010 - 1.018)
Color: 32.9 (22.0 - 40.0)
Alcohol: 5.43% (4.2% - 5.9%)
Bitterness: 33.83 (25.0 - 40.0)
Ingredients:
7 lbs English 2-row Pale
2 lbs Oats Flaked (0.75lbs can be toasted at 325F to your liking. I shoot for a medium tan color)
0.5 lbs Barley Flaked
1 lbs Crystal 60L (middle of the road crystal, 40L would be good too)
0.5 lbs 2-Row Carapils® Malt
0.75 lbs Chocolate Malt
0.75 lbs Roasted Barley
0.5 lbs American Black Patent
1.25 oz East Kent Goldings (5.0%) - added during boil, boiled 60 min
1 oz East Kent Goldings (5.0%) - added during boil, boiled 20 min
1 vial White Labs WLP004 Irish Stout
MASH TEMP 155F
NOTE for mashing: You may want to incorportate a 0.5lb to 1lb of rice hulls into this mash to prevent a stuck sparge. This helps increase the filtering potential of the grain bed.
Partial Mash option: (assumes a 60% mash efficiency)
In place of the 7lbs base malt, mash in with 2 lbs of english malt and 2 lbs of flaked oats at 155F. Hold for 60minutes to convert base malt and Oats.
Place all other crushed grains and flaked barely in grain bags and steep in brew pot at 140F for 30 minutes or until good color is acheived.
Add 3.5lbs of light LME or 3LBS light DME to brewpot after steep. Collect and add the sparge from the partial mash to brew pot. Bring to boil and proceed as normal.
Extract with grains: (assumes a 40% steeping efficiency)
Replace the 2 lbs of flaked Oats with 0.5lbs of oats. Place oats, flaked barley and the remainf crushed grains in grain bags. Steep in brewpot water for 30 minutes at 140F or until good color. In place of 7lbs of base malt use 6.5 lbs of light LME or 5.5 lbs of light DME. Remove bags, add extract, bring to boil and proceed as normal.
Notes and substitutions:
Yeast: If Irish yeast isn't to your liking this recipe would also work well with any of the british/english strains. I know of one brewer that makes Oatmeal Stout using American Ale yeast (WLP001). Regardless of choice, make a good starter, or pitch 2X the yeast listed. Aerate that wort really well.
Oats: Just for clarification, I use Quaker Old Fashioned Oats, not quick oats.
Hops: I listed the recipe with EKG, but you can go with any combo you like, just watch that bittereness level, so you'll need to recalculate it if you use a hop with a different alpha level.
I like it, I like it a lot. Do we have a factor that we want to tweak? Or are we all going to do the same? Not to add confusion but maybe have groups volunteer to have a choc stout, vanilla stout, coffee stout, chambord stout, cream stout? if we do a swap we can control so others can try variations?
Eureka I found East Kent Goldings! I couldn't find them anywhere but Midwest supplies has 'em.
Score!
I'm not a Stout man.....but I'm going to brew this up....sounds good Brewchez....I'll enter it in some competitions next year after it's sat for 6 months.......I'll keg 2.5 gallons and bottle the rest......
Alright, its time to get brewing!
