Here is the Russian Imperial Stout (RIS) recipe we used. I have been using some version of this recipe for 6 years.
5 gallon batch size
14 lbs American 2 row Pale Malt
1.5 lbs Roasted Barley
1.5 lbs Chocolate Malt
1 lbs Belgian 2 row Pale Malt
1 lbs Biscuit Malt
1 lbs Wheat Malt
1 lbs light Munich Malt
1 lbs Flaked Oats
0.5 lbs CaraMunich 60 L
0.5 lbs Black Patent Malt
0.5 lbs Special B Malt
11.5 HBUs Fuggle pellet hops @ 60 mins
12 HBUs Perle pellet hops @ 60 mins
21 HBUs Magnum pellet hops @ 60 mins
1 oz EKG pellet hops @ 10 mins
0.5 oz Ahtanum plug @ 0 mins
0.65 oz homegrown Cascade whole hops @ 0 min
1 wyeast 1968 pack - This is the london ESB yeast. One of my favorites.
1 tsp Irish moss
carbon filtered tap water
5.2 mash buffer
We have found that there is extra sugar, flavor, and color left, we make a porter with the seconds. This is in style 12. This one is for the benefit, so we will be rebrewing the style later.
2-4 lbs DME as needed to beef up the starting gravity
8.7 HBUs Magnum pellet hops @ 60 mins
1 oz EKG pellet hops @ 10 mins
1 wyeast 1318 pack. I went with the London Ale yeast, since Fermentations only had one 1968. I could have gone and propogated the ESB up, but sometimes I am lazy.
1 tsp Irish moss
carbon filtered tap water
