Ok - So I'm still very much a novice 2 years into this. I've been tasked with coming up with a spiced oatmeal stout for a friend's wedding. (I'm also brewing up a scottish, but I'm pretty confident and experienced with the recipe I'll be using for that). I have no idea how to use an app like beersmith. My method is largely like deathbrewer's method for doing all-grain. I use two 5 gallon pots with about 2.5-3 gallons in each, and basically mash the grain twice using the large nylon net-bag that stretches over the lip of the pot and a mash paddle - once in each pot to get good use out the grain). I'm assuming roughly 75% efficiency?

I've looked at a lot of different oatmeal and american stout recipes, and I've cobbled this together. I brew to taste, not to style, so this is a bit of a frankenbeer, I'm going to try to go big and complex on this one. I'd love it if someone could plug my numbers in and tell me where I should be hitting with my OG and FG, etc. I'm completely guessing. I've decided to name it Krydder (spice) oatmeal stout.

0.50 lb Barley, Flaked (for head retention)

I wanted something a little more aromatic than Fuggles/Golding, with a little more bittering to counter the sweet/big body. Leave the hops in primary.

Finally found a calculator. Looks like my hops/IBUs are low, and I'll need a beefier yeast. WLP002 can only get these grains to about 8%, but their WLP775 will take it to 9.6%. Although, that's a cider yeast. Seems their WLP004 Irish Ale yeast will take it closer to 10%. Hrm. Hrrrrrrm.
