This beer is a straightforward Russian Imperial Stout, which I gave a long three hour boil. Because of that I got a reasonably good mash efficency given that I only did two batch sparges. I have bottled a couple of liters, but will put the rest of it in a keg with two Madagascar Bourbon vanilla beans infused with MacAllan 10 yo cask strength single malt whisky.
Added 1ts CaCO3 (calcium carbonate) and 1ts to boil.
The batch was brewed 2009-02-03.
