Motherland Imperial Stout

I brewed up my first Russian Imperial Stout bier this past December, 12-10-09 to be exact. I brewed up about 4.5 gallons including the yeast cake I dumped the bier onto. When it was all said and done the brew yielded about 3.5 gallons of finished bier. I let the bier sit in primary for 8 weeks, no worries about autolysis here! At the 8 week mark I bottled 1/3rd of the batch as 'standard'. I moved the other 2-2.5 gallons to secondary where they sat for 4-5 weeks on whiskey soaked hickory chips. That's not a misprint, I used Hickory! Screw French oak... I'm southern give me the hickory! Maybe I'll run through that process on here sometime, but for now all you need to know is that I hand selected the wood, gave it a quick dip in boiling water, rinsed, toasted, & soaked in whiskey!

That brings me to this past weekend where I bottled the 'wood aged' RIS. Since the bier was extremely clear I decided to re-pitch a little yeast, about 1/4 pack. Also of note is that I bottled half of the 'wood aged' bier and added about 12 oz. of strongly brewed Kona coffee to the remaining 1+ gallon and bottled it. Thus I got 3 different biers out of this one brew which is always exciting!

Here is the recipe with accurate numbers etc.

My mash schedule was along the lines of 146 degrees farenheit for 75 minutes and 155 for 30 minutes with a standard mash-out. The early tasting results are that the bier is substantially malty sweet, fairly strong bitter/dark chocolate tones, mild coffee, hints of caramel & toffee, with black currant & stone fruit perhaps a bit of fig. While it is yet young it is showing substantial promise for my first 'big' bier.

As always I enjoy building labels for my brews, particularly those that have some meaning or significance to me as a brewer. Obviously crafting a bier that I plan on having bottles of around for 2-4 years is an occasion to celebrate. Below is the finalized label for Motherland. Note the boxes in the bottom right hand corner. I will check the appropriate box denoting which version of the bier each bottle is.
