A recently brewed Stone Double Bastard is missing some of the Chinook goodness that comes in the bottle.
The 5.5 gallon batch has 5.5 oz. of Chinook (12.7 AA) - 3.5 oz. at 90 minutes, 1.5 at 15, and .5 at flameout (about 180F). It is plenty hoppy but that distinctive Chinook aroma and flavor is absent. OG and FG is 1.104 and 1.024.
With that said, I am considering dry hopping.
How much of the 12.7 AA Chinook will I need to get noticeable flavor and aroma out of the keg?
