Old Rasputin Imperial Stout clone
Folks, has anyone tried the clone recipe from "The Best of BYO" ?
It claims that North Coast releases this to the public within a month. But... I've read that this can be quite harsh when it's young and that it should sit a least six months before consumed; any thoughts ? :mug:
I've done the recipe and it was fine after a month (yeast hadn't yet cleaned up all the acetaldehyde from being bottle conditioned though). It did improve over the next month or two.
Unfortunately, my batch did not last more than two months, so I have no idea what it would have been like at six months.
ok cool; I'll give it a shot after a month
Old Rasputin Imperial Stout Clone Questions
I'm going to be brewing the below recipe (all-grain) next week and I had a few questions.
1) Has anyone brewed this recipe? When I input the recipe into BTP, the SRM comes out low and below the recommended range for this style. I've had Old Rasputin before and I'm pretty sure that the color is pretty close to black. If BTP is correct, and the color is light, what would be the outcome if I doubled the chocolate malt? I know it would darken the color, but how much would it change the overall taste?
2) I'm going to use a H20:Grain ratio of 1 for this recipe. With a big beer like this, any recommendations on my expected mach efficiency?
Thanks in advance,
Old Rasputin Imperial Stout (clone)
5 gallons, extract with grains
OG = 1.090 FG = 1.022 IBUs = 85-95 ABV =9%
9.9 lbs. Coopers Light malt extract syrup
1.0 lb. Hugh Baird Carastan malt
0.5 lb. Hugh Baird Brown malt
0.5 lb. chocolate malt
1.0 lb. crystal malt (120° L)
0.25 lb. roasted black barley
22.7 AAU Cluster hops (bittering)
(3.25 oz. of 7% alpha acid)
9.0 AAU Northern Brewer hops
(aroma hops) (1 oz. of 9% alpha acid)
8.8 AAU Centennial hops (aroma)
(1 oz. of 8.8% alpha acid)
1 tsp Irish moss
White Labs WLPOO1 (California Ale)yeast or Wyeast 1056 (American Ale) yeast
0.75 cup of corn sugar for priming
Step by Step
Steep the crushed malts in three gallons of water at 150° F for 30 minutes. Remove the grains from the wort, add malt syrup and bring to a boil. Add the Cluster (bittering) hops and Irish moss and boil for 60 minutes. Add the aroma hops (Northern Brewer and Centennial) for the last two minutes of the boil. When you are done boiling, strain out the hops and add the wort to two gallons cool water in a sanitary fermenter. Top the fermenter off with cool water to 5.5 gallons. Cool the wort to 80° F, aerate the beer and pitch your yeast. Allow the beer to cool over the next few hours tó~ 68-70° F, and ferment for 10 to 14 days. Bottle your beer, age for two to three weeks and enjoy! (Yes, that's right, this beer so well- balanced that North Coast releases it to the public in less than a month.)
Replace the light syrup with 14 lbs. of pale malt. Mash all your grains at 152° for 45 minutes. Collect enough wort to boil for 90 minutes and have a 5.5 gallon yield. Decrease the amount of bittering hops to 2.75 oz. of Cluster to account for the increased hop extraction efficiency in a full boil. The rest of the directions are the same.
My friend BobG brews a nice Rasputin Clone. Here is the link to his recipe. I have had it from him as young as 1 day in the keg. It was a bit yeasty that day, but not at all harsh.

I am brewing the recipe from the magazine now. I did make a couple minor alterations. I opted to sub for the carastan malt. My lhbs doesn't carry it. I also adjusted the hop schedule a tiny bit to have the ibu come out correctly and converted the malts to LME and opted for nearly a full boil.

Thought I'd add some tasting notes here.
Its been a solid 2 months months in the bottle. I have to say this brew was great as soon as it was carbed, however its bordering on godlike 2 months later. Its very balanced with some malt and sweetness and its a high IBU brew. The above recipe worked great.
Oh well, it's already in the tank and bubbling at a steady rate... just wondering what the difference in the times might mean for the finished beer.
The OG was around 1.080 - 1.085.
I have it in secondary now, it's been in there 17 days with the temp at 68-70 degrees. I was planning to keep it in there at least 60 days since many brewers have recommended this for better results.
It's my second all-grain beer and first stout.
The OG sounds decent. Record that, and if you're all grain batches are consistently low (low efficiency) you can just add more basemalt to your recipes to make up for it, or change your process. Keep in mind that big grain bills like this tend to hurt efficiency, hence the longer boil.
I usually primary "big" beers 3-4 weeks. Your mileage may vary.
