I stopped at LHBS last night and picked up 2 oz of Centennial 9 IBU. One of the employees inquired on my project. After explaining my dilemma, he walked me over to where the additives were and handed me a syringe of "hop shot". He instructed me to use 2.4 ml in 5 gallons of boiling wort for 1 hour to get the results I wanted. A bit skeptical about this, I purchased the product along with the hops.
It's hard to get IBU's from boiling hops in plain water so I would advise against that.
Once home, we bled one of the 5 gallon corny kegs of co2 and removed 1/2 gallon of the sweet beer. We then slowly brought this (along with 3 quarts of fresh water for evaporation) to a boil and put the 2.4 ml as suggested in the wort for 1 hour. When this was complete, we cooled down the wort and strained. We then put it back in the keg we drew this from and SLOWLY mixed this back and forth and re-charged with CO2 enough for a taste.
It was a cloudy beer but our desired results were achieved!
The beer is now balanced enough to make it palatable to drink, thanks for all the suggestions this was a lesson I won't soon forget!
