Hops: Partial boil vs full boil

From messing with beer smith ive realized the boil volume has a big impact on predicted IBUs, Higher gravity wort lower hop utilization blah blah… I thought maybe NB extract kits would have more hops since the extract instruction say 2.5 gallon boil but after being curious enough to check i realized the hop amount are the same

It takes me an hour to get 3 gallons to boil not sure i could do much more. I know the predicted IBUs will be different but would the difference in taste be noticeable compared to the like all grain kit? For example Innkeeper extract with partial boil to Innkeeper with full boil. Could i scale up the hops? Would i only want to scale up the bittering hops?

ive been listening to basic brewing about Ibus but havent found anything about this, i think it’d be an interesting test…

With a full boil you will get higher utilization, so you would actually want to scale down. One nice thing is that you have beersmith to help with this.

Extract kits are designed with the partial boil in mind. Not sure as I haven’t brewed an extract in years but I’m not sure the IBU difference is that different.

Im doing extract with partial boils. Youre thinking of it in reverse of me. i’d think full boil would be the ideal for a kit. The hops are exactly the same when its offered in both extract/all gain kit thats what i was surprized about

There are a lot of advantages to full boils and I would recommend this if possible.

The kits are designed for partial boils. Since they put the same amount of hops in I’m assuming (like I said, haven’t brewed extract in awhile) the difference isn’t that noticeable. I could be wrong about the amount of difference though. Point is, nobody is going to be able to tell the difference between 20 IBU and 25 IBU beers.

When you put your recipes in beersmith with the parameters set for a partial boil, are the IBU’s within or close to style guidelines?

Well i have a recipe in beer smith at 2.5 gallon boail its 32.9 IBUs and at 5 gallon boil its 46. Im not sure if i’d even be able to tell the difference. At the end of the day just want to brew the best beer i can with what i have to work with
