Default Help with Upscaling an Cascade IPA Recipe

I have the book True Brews by Emma Christensen. This book has 1 gallon recipes. I recently made her 1 gallon IPA recipe. The recipe is as follows:

2 lbs American 2-Row
.5 lb Maris Otter
.5 lb Crystal 20

.87 oz Cascade 60 minutes
.3 oz Cascade 20 minutes
.3 oz Cascade 1 minute

When you put this recipe into Brewer's Friend the IBU's come out around 120. I brewed it anyway and it turned out great. I'm planning to upscale the recipe for a 5 gallon batch and it seems like a ridiculous amount of hops. If you scale everything by 5 the hops come out to something like this:

4 oz Cascade 60 Min
1.5 oz Cascade 20 Min
1.5 oz Cascade 1 Min

IBU's would be 127

My 1 gallon batch tasted great but I'm just wondering if I really need that much hops. Are they being utilized effectively? Am I just wasting money on hops?

Yes, recipes scale just like that.

Most breweries bitter with higher AA hops, so that would be a sub you could make to cut the cost. Honestly though, most of my IPA's have 8oz+ of hops (including dry hop) for a 5 gallon batch.

Thanks for the reply. I think I'll roll with it and give it a try.

Sounds about right. My suggestion would be to look at the IBU contribution of each hop addition and scale hops to match it. When scaling a recipe up the grist is typically scaled 1:1 but hop utilization is on a curve, so 1oz:1gal would scale to something like 4oz:5gal. Make sense?

Good luck
