Dry Hop lbs per bbl
Q: Hello!  I'm looking for some reference regarding dry hopping quantities regarding to style. Something that would guide me in lbs/barrel. Thanks

A: The rate of hops used per barrel for dry hopping depends on quite a few variables. Some to consider: 
  •  Hop variety & type of hop product used 
  •  Hop oil content
  •  Condition/age of hops to be used
  •  Method of dry hopping (slurry, recirculation, stirring, static bags, torpedo, etc.)
  •  Contact time
  •  Temperature during dry hopping
  •  Presence of yeast/stage of fermentation

With so many different approaches to dry hopping and process variables, it is not possible to give a 1-size fits all answer per beer style or brewery. Furthermore, what is the desired outcome – to maximize aroma, flavor, or both? 

I recommend starting with 1-pound per bbl. Assuming a good process (get rid of that O2!) a 1-pound per bbl dry hop is sure to give you some good aroma extraction. If your process is efficient, you may be able to achieve good results at a much lower rate (< half a pound per bbl). Note that many brewers have experienced diminishing returns; 2 pounds per bbl will not yield double the aroma.

Here are some great MBAA resources where you can learn more about dry hopping:

Happy hopping!
