this IP is be slightly on the Northern Brewer Dead Ringer recipe.  it contains lots of Centennial hops, plus a fair amount of Cascade to finish things up.

 

what makes this beer unique is the addition of rhubarb juice in the boil process.

Special Procedures

I cut 32 oz of fresh rhubarb into small  pieces, and froze them the night before brew day.

I thought about putting these in the mash, but instead,  I thought them crushed him and squeeze this much juice is I could out of the rhubarb.  I was only able to get about 12 ounces of juice, so I put the remainder in a fine mesh bag, and hung it in the boil kettle for the last 15 minutes. I added the juice at the same time.

I plan to collect another 12 to 16 ounces of rhubarb juice, and add it to the secondary (6 to 8 ounces in each).
