North the Eighth (VIII)

How much grain can we get in our mash tun? This is a question that has haunted our brewery from the beginning. How do we find out? Let’s make a Russian Imperial Stout for this year’s North, our winter seasonal. So enjoy this huge stout, once popularized by Russian tzars and their families, while taking refuge from the cold outside. Imagine streams of black and roasted barley cascading down to the brewery floor during the sparge, and the groans of mechanical rakes trying to cut through the grain bed. How much grain can we get in there? The answer, my friend, is in this bottle.
