Imperial Stout...perfect time to try it.
 

Imperial Stout

10 gal

OG 1.118 / FG 1.030 / IBU 70 / SRM 50 / ABV 11.4%

30 lbs Pale Malt
7 bls Flaked Oats
3 lbs Roasted Barley
1 lb Chocolate
.5 lb Crystal 60
.25 lb Crystal 90

5lbs Brown Sugar

4 oz Magnum (45 min)
2 oz Centennial (10 min)
Irish Moss

US-05 yeast

Mash 146 for 90 min, boil 90 min, Ferment for 4 weeks in primary around 65* - 70*

Any advice on drying this out more than 1.030 without raising the percentage of sugar? I mean, if I went to 15% I could get lower, but I feel like that is cheating...am I wrong here

Swap out some Pale Malt with corn sugar in the boil, maybe?

Yeah more sugar aught to do it, or if you want to get risky use some beano :P

I'm kinda new at this, but 7 lbs of flaked oats seems like overkill for a 10 gallon batch. I just did an imperial stout and used under 1.5 lbs for a 5 gallon batch. Again, I'm kinda new at this, but 7 lbs of flaked oats seems like a lot.

I am trying to keep it around 15%-20%. The last time I made a 10 gallon stout it came out to that ratio and was delicious

Using regular table sugar vs. brown will probably dry it out even further.
