Juicy Banger: how to brew a Grapefruit IPA recipe

If you’ve been following the Craft Beer Channel for a few years, you might be aware that we once came up with a grapefruit IPA recipe and brewed the beer with Camden Town Brewery and a bunch of other beer nerds. It was a lovely day, but the shoot was a bit haphazard even by our standards. Suffice to say, if we had known it was going to get 45,000 views, Jonny wouldn’t have pretended to be a female fashion vlogger for the majority of it…

After nearly two years of thumbs down, abusive messages and comments like “WTF is this guy doing? Where’s the bloody recipe?!” here we are finally with a perfected recipe of the Juicy Banger we brewed that day. When we made it, the term “juicy” was in its infancy. The hazy ultra-fruity, soft bitterness IPAs were being brewed by then, but only the NE of America had really tasted them. For us back then, it referred to beers that were fruity rather than dank and/or resiny – beers like Pressure Drop Pale Fire, Ballast Point Sculpin and Beavertown Gamma Ray that had pronounce pith and juice notes to the hop character. When we teamed up with Camden Town we wanted to take that pith a little further by adding grapefruit peel.

Since then the juice has been very much set loose around the hoose, so when we sat down to plan a new recipe we thought we’d stay in keeping with the original premise to offer a counterpoint. That said, there were some inherent flaws in the original beer which we have ironed out. We wanted it cleaner, less astringent and even more pith-forward. After some rebrews and redrafts, what we have is a crisp, seriously grapefruity beer with a lightning quick finish. Even on our simple set up it came out really well – singing with juice but being deceptively easy drinking and dry. So here it is – our true Juicy Banger. Old fashioned, but still on point.

  1. Hi Guys! That sounds fantastic! Going to brew this sometime before summer hits 🙂
    What yeast did you use? I guess something neutral (US-05, Nottingham) would do the job?

    • Good lord, can’t believe we forgot that! I’ll amend above but it was WLP001 – so a clean west coaster.

  2. Yes i thought so 😀
    Did you do anything to your water? I might add 150g of acidulated malt to get the residual hardness down…

    • Yeah we did, but we didn’t mention it here as everyone’s water will differ. harder water for hoppy beer is a good idea though…to a point. You’ll want a Burton kinda feel to it

  3. I’m trying to scale to a traditional US 5 gallon recipe. Is the 30L the boil volume, or what ends up in the bottles?

    • Apologies, I’ve amended above. We used 29.2 litres of water – 18l mash, 11.2l sparge. Boil volume around 18l, 16l into fermenter.

  4. I’ve got a couple of other brews planned so trying to maximise my hops, how do you think Citra would do in place of Amarillo?

  5. I think your Citra for Amarillo swap would work out in the sense that they aren’t far off from one another typically. Some Citra Hops I find to be more Herbal vs. the Amarillo Hops I find to be more Floral depending upon origin.

  6. Great recipe, will try it later this week!
    One question though, you mention in the beginning a brewhouse of 30l, so I read this as 30 of final product IPA.
    When I add up the mash volume and sparge volume in the recipe, you only have 22.2l of liquid, so you will end up with way less (boil-off and sparge remaining in the spent grains).

    Am I reading the reciping wrongly?
