I normally use nylon mesh hop bags for my pellet hops when I brew and I'm not sure if I should calculate a lower utilization because of the hop pellets being restricted in a bag? (Usually less than 2 oz. in a 8x10" bag)Boiling my bittering hops for 60 minutes in a 1.058 wort I us 27% as the utilization rate. Should that % be lower when the hops are bagged?

As far as i can tell, the restriction of the hop bags equals the advantage of pellets over whole hops. That means that if you use pellets in hop bags you can use the same calculations you would for whole hops. I limit the amount to no more than 1.5 oz. per bag. |

I use those big paint strainer bags that Home Depot sells. The hops are quite free to roam around in those big bags, it's hard for me to imagine that there is a noticeable IBU loss due to the bag somehow blocking release of bittering. |

I don't use hop bags unless I have a beer that is heavily hopped like an IPA. In my 10 gallon system, I can do about 7 ounces of all pellet hops before I have to worry about my false bottom getting clogged from my sanitation loop.
My process of using a sanitation loop will create a filter bed of hops on my false bottom. I prefer to use whole or plug hops, but many times I use a mix. When I have a decent amount of whole or plugs I don't even worry.
Any of the hops that make it through the filter bed settle out in primary. |

MT, to "enhance" what others have said, if the hops are packed tight into bag, there will be more of a loss than if they are loose. 10% is the norm for lowering AA% in bag.
I personally think there's a bigger difference in what the ACTUAL AA% is compared to what we THINK it is... Especially for stored hops. |

So Hophead,
are you saying I should figure a 10% loss for pellet hops that are NOT tight in the bag?
thanks
