As good as it gets..
I brewed this recently and made some modifications (based on a friends thoughts on it). I added .5 oz Cascade hops at each hop interval (so 1.5 oz Total) and then 2 oz extra for dry hopping. I also used the peel of one whole grapefruit and soaked it in the Vodka as well. I dry hopped all in a bag to avoid the mess. 3 weeks in primary and dry hopped one week in primary.. on tap at 4.5 weeks and one of the best brews I have made. I like it better than the original, not as sweet, but damn tasty and a hit around my house. I ordered another kit as soon as I tasted it and its fermenting as we speak..

Great brew but make sure...
This is a great brew, perfectly timed for warmer weather. One thing though - absolutely make sure you contain the pulp. CONTAIN THE PULP!!! This may be the time to invest in some hop blockage or at least use a mesh bag. I didn't and my siphon and bottling gear got all clogged up many many times. Hey NB!...you might want to write that in the directions or product description. That said, this beer totally delivered and I'm ordering it again.

As a big fan of the brewery version of this beer I had to try it. Thought it would be a tall order to get close to the original. 7 days primary, 21 days secondary and did the grapefruit and dry hop additions for the last 9 days. Turned out AWSOME! 6.69% ABV, wonderful grapefruit aroma and flavor, nice and bitter but not too much. Ordering again

Grapefruit = very bitter
First of all I like bitter beers but this brew was just over the top bitter. I've kegged it over 3 months ago and the bitterness has died out significantly but it's still very strong. It's hard to drink a single pint.I've soaked the grapefruit peels in vodka as directed and added both to the fermenter (without draining vodka) so possibly that's part of the problem.I definitely won't brew this beer again.Just a side note that may help you to finish all 5G - I tried adding a little bit of raspberry syrup to the glass to sweeten it up and it helps to kill the bitterness and seems to do the job.

Great spring/summer IPA
I bought this because I was making some w00tstout with Wyeast 1056 and could easily make another starter for an additional brew. Primary for 2 weeks (including 8 days of dry hopping / grapefruit rind additions). I sanitized the grapefruit with a few oz of Bacardi Limon instead of vodka since I like the citrusy flavors it imparts. No secondary; bottled with no problems and it was fully carbed in 7 days. I'm drinking one now 2 weeks after bottling, and the light grapefruit / citrus flavors pair well with the base IPA to create a very crushable beer. I don't really feel like spending $18 on a 6 pack of the "real thing" to see if this beer is a good clone; rather I will simply say this is a great beer kit if you like the idea of a citrus IPA. I will definitely brew it again soon to have it ready for the hottest part of summer.

Excellent summer beer
Got 2 kits of this for $20 each (thanks for the sale!). It made a great beer and I am drinking one right now. If you are looking for an even bigger grapefruit flavor, I would recommend sanitizing the grapefruit rind with grapefruit-infused vodka for several days before adding it all to the beer (start soaking it on brewday). When you add the grapefruit mixture to the beer, throw in the dry hops and let it go 1 week more. I bottled each 5gal batch with a priming solution consisting of 4 oz corn sugar with 2g of rehydrated CBC-1 yeast, and it was fully carbed in 5 days and it tasted great. Thanks NB for the kits, and the awesome deals!

I brewed this back in May for the hot summer days here in Utah. I would HIGHLY recommend either bagging the grapefruit peel or being ready with some sort of cage around your racking cane. This was a hot mess going from secondary into the bottling bucket due to the loss of suction in the last third of the carboy. While i ended up with a ton of sediment in the bottles it had little impact on the flavor which was wonderful. This was my 4th kit and has been very educational as the beer matured. When bottling the hop notes were tremendous and the grapefruit was no where to be found. A month later the hop character and the grapefruit character took on an excellent balance and this was easily better than the commercial grapefruit IPA's available to me. Now after an additional few weeks the hops continue to subside and the grapefruit is taking a dominant role. While still tasty, i miss the hop balance and will likely consume of the remainder of the batch before all hop flavor disappears further. This is a great kit and i will definitely be revisiting it in the future as a part of my spring rotation.

I love strong, hoppy beers and grapefruit, so this one is a winner. Beautiful color and fantastic taste. I used my Fast Fermentor and unfortunately clogged the detachable bottom since there's a lot of hops. I also pulled a bonehead move and just dumped the grapefruit zest in instead of using a bag. I'm about to order my next batch, this will be my go to IPA.

This is the first NB beer kit that I have made (of about 8 or 10) that came out stellar. This is the beer I've been looking for.

The magazine shows the brew as having a pink color. What food colorings do I need to add to get it looking pink?
A shopper on Dec 19, 2016
BEST ANSWER: That's a good question as mine was not pink as well. I would also not advise putting the grapefruit peel in secondary without some type of sac so that it can be removed. Made bottling difficult.
Has anyone tried brewing this recipe kit and omitted the grapefruit peel/vodka in the secondary in an attempt to replicate the regular Sculpin and if so did it turn out decent? As in close to the real Sculpin? Thanks
Sean on Aug 24, 2016
BEST ANSWER: We have not heard directly from anyone who had done it this way, but we figure it would be pretty darn close! The Grapefruit version is quite tasty, and so I'm sure it would be good without the grapefruit addition as well. Give it a try, and let us know how close it is! -Mike W, Northern Brewer
I purchased the Grapefruit Pulpin' Extract Kit and was wondering if there was a good way to filter the beer after secondary fermentation, but before adding priming sugar and bottling? Would filtering be a bad thing? I think it'll be a great recipe, but I did notice there are a lot of hops in this recipe and they don't all seem to settle to the bottom before I siphon out of secondary fermentation and into the priming bucket.
Kellen on May 28, 2016
BEST ANSWER: I have the same kit, will dry hop and add the grapefruit/vodka in a week. I've pretty much decided that I will strain it when going into the bottling bucket. What has worked for me in the past is to buy a paint strainer bag and put over the end of the racking cane secured with small zip ties. All sanitized of course.

Good luck, if you like this brew you should try Kama Citra. One of my favorites.
Just use the peel of the grapefruit, not the actually fruit for the soak? Should it be chopped up or grated or anything?
Matthew P on Mar 25, 2016
BEST ANSWER: You do not need to go and buy a grapefruit. The kit comes with a bag that already has chopped up grapefruit peel. All you need is the 4 oz of Vodka.
Brewing this tomorrow...but my question is for the grapefruit peel. What is the recommended way to do this...soak the peel in vodka for a few days and dump it all into the secondary or just soak it for a few minutes to sanitize and only add the peel and not the vodka?
T C on Feb 27, 2016
BEST ANSWER: Howdy Todd,

You will want to soak the peel in 4oz. vodka for 24-48 hrs to help extract the flavor, and then add both the peel, and the vodka to the fermentor 5-7 days prior to bottling!
Just brewed and have nearly a gallons worth of hops sitting at the bottom in the first hour of fermentation. Should I add another gallon of purified water to compensate for the expected loss? OG reading was at 1080 so it shouldn't get too watered down, right?
A shopper on Feb 11, 2017
BEST ANSWER: There will always be settling, but definitely try to leave as much of that hop sludge in the brew kettle as you can before bringing the rest up to 5 gallons. That will get you closer to what Northern Brewer intended with the recipe.
OG target on my brew sheet was 1.065 so I'm pretty sure you'd be okay to add more water. You are probably correct that adding another gallon to 5 gallons should water it down 20% to 1.064. Personally I leave it just a little over target, but at 1.080 you may be completely changing the taste of the beer. One thing is for sure.. if you leave it as is you'll be ending up with a higher ABV after fermentation!
I just brewed a batch of this over the weekend. When it is time to add the peel and vodka, could I perhaps use grapefruit vodka to enhance the fruity flavors?
Alvin S on Jul 10, 2017
BEST ANSWER: The flavor present in a grapefruit vodka is probably going to be too subtle to be noticeable in the beer. I believe the vodka is primarily to sanitize the grapefruit peel. You are really going to get the grapefruit flavor from the peel. Allow the peel to soak in the vodka while you are waiting on primary to finish. The aroma from the peel will be wonderful. This is a great kit and won't last long.
Finally legged this bad boy after 5 days of dry hopping and grape fruiting. I found that the first 4 beers I've had have a spicy taste to them and I'm getting no grapefruit at All except for a faint scent. Do you think it's the simcoe hops that haven't mellowed yet? It's drinkable but the fact that there's no grapefruit taste has me scratching my head.
Louski on Sep 16, 2016
BEST ANSWER: Mine did not have too much a grapefruit taste either, although it was a very good beer overall. I think the only way to get a real grapefruit taste is to add some kind of flavoring just before bottling/kegging.
When adding the vodka/grapefruit mixture in the dry hopping process, is the vodka also added or is the grapefruit peel removed from the vodka and added to the fermenter?
Steve B on Aug 19, 2016
BEST ANSWER: Yes, the Vodka is also added along with the grapefruit peel. While the grapefruit soaks in the vodka most of the flavor and aroma is extracted out and into the vodka. You will want this flavor and aroma present in your beer. Some may suggest discarding the grapefruit peel and ONLY adding the vodka to your secondary vessel, but one can assume by adding both (vodka and grapefruit peel) the beer will get the MOST of the flavor blended in. Racking (whether it be bottling or kegging) will be difficult with these grapefruit peels. I would suggest when racking filtering out all of those peels with a nylon filter or something of the like. These will clog easily in bottling wands or valves and will become a headache. Or even worse, end up in your bottles or kegs. I once stuck my racking hose in a nylon filtering bag (in my keg) and as soon as keg was full, I slowly pulled nylon bag out... ALL debris and any remaining hop gunk was instantly filtered without harm of oxidation.
When instructed to soak the peel in vodka then add to the fermenter, do you add the entire solution of peel + 4oz vodka or do you discard the vodka and only add the soaked peels?
Steve J on Jun 8, 2016
BEST ANSWER: Yes, you would add the entire mix, peels and vodka, to the fermenter.
Just opened up this kit. It has a 6 lb gold malt and a 3.15 gold malt extract. Is this right?
B A on Apr 30, 2016
BEST ANSWER: Yes that is correct. Cheers !!
I have been looking for a Schofferhofer Grapefruit Hefeweizen Beer kit. My wife loves this beer. Will this kit come close? Can grapefruit juice be added? Any help or recommendations would be very much appreciated.
H U on Apr 1, 2016
BEST ANSWER: This one is not sweet and is more bitter so I think it would be too far off. To make a clone of that beer, take a normally brewed hefeweizen, mix in grapefruit juice and then it must be kegged. The beer should be sulfited and kept cold to preserve that sweetness from fermenting out, and that means it can not be bottle conditioned with ease. It has the grapefruit but the base is an IPA. If you can't keg, consider brewing a hefeweizen and adding some grapefruit peel like in this recipe - though it would not be 'sweet'. I hope this helps. Cheers!
Is secondary fermentation required or can I just leave it in the same container? Don't have a unit to transfer it to and so I was wondering what happens if I leave it in the primary fermenter for the 4 weeks. Thank you.
J E on Mar 25, 2016
BEST ANSWER: I'm not sure that I can best answer the question, because all of my beers are kegged and I typically don't ever move an ale to a secondary per John Palmer's book. With a good yeast starter, I usually leave my beers sit in primary for 3-4 weeks anyhow. At that point, the beer is transferred to the keg and all of my hop additions (and in this case, grapefruit peel) are added directly to the keg.

When I first started brewing beer many years ago and bottled, I used to do a secondary. Over time, based on what I've read and from other's experiences, I quit the practice and would do hop additions directly to the primary after hitting my targeted final gravity, wait the 5-7 days, cold-crash, and bottle. I personally could not tell any difference. Hope this helps!
In a follow up to Todd C. my peel also absorbed all of the vodka. Should I splash a bit more on it right before I add it to secondary to make sure it's sanitized?
KRISTINA S on Mar 24, 2016
BEST ANSWER: I did just that- added about half a ounce of fresh vodka mostly to loosen the pulp some so I could spoon it into the car boy. I guess a second benefit is the sanitation factor. The vodka I used was Absolute Citron. Anyway, this brew was gone in record time once my beer drinking friends found out about it.
This may seem like a ridiculous question - but I see "apricot" mentioned. I checked the ingredients and it doesn't seem to be a component. As any Marine can tell you, apricots are avoided at all costs due to bad luck. I'd love to give this kit a whirl, can anyone verify that there is in fact ZERO apricot ingredients? Thanks in advance.
J E on Feb 24, 2016
BEST ANSWER: No, there's no actual apricot or apricot extract in the kit. Simcoe hops have a flavor that many find similar to apricot, especially if they're used as in dry-hopping, so that's where the flavor description comes from.
I got 6.9% ABV. Is that about right? I don't see anywhere in the directions where it gives a projected ABV. I just want to make sure I am reading my Hydrometer correctly
J A on Feb 17, 2016

That sounds like an appropriate ABV for this kit.
Does this beer really only have an IBU of ~40? Seems low compared to reality.
James C on Jan 2, 2016

Yes, it does seem low. Part of the reason for that is that most IBU calculators consider hops added at flameout or dry-hopped to be 0 IBU's, since (in theory) there is no time for the heat to isomerize the alpha acids. However, some AA's do isomerize when hops are added at flame-out, and the oils of the late addition hops can also lend a "perceived bitterness." Perceived bitterness can also refers to the BU:GU ratio; for instance, if two beers have identical IBU ratings, but one has a significantly higher OG, all that added malt sweetness will actually make the beer taste less bitter.

I hope that helps!


Has anyone else tried substituting the grapefruit for other citrus like pineapple, oranges, blood orange etc?
Marvin G on Jun 23, 2017
BEST ANSWER: I did not substitute the grapefruit peel for anything digfferent but I did soak it in vodka for a few days. It turned out very well.
Instruction state target OG of 1.065. What is the target FG?
A shopper on Mar 15, 2017
BEST ANSWER: My OG was 1.046, and FG was 1.014
Has anyone tried making this a hazy NE style IPA by adding more of the hop bill in the secondary vs in the boil I was thinking 1oz chinook at initial and whirpool then dry hopping 1oz Amarillo, 2oz Cascade and 1oz Simcoe? Kinda curious what people think trying to keep bitter finish down while enhancing the floral aroma and flavors.
A shopper on Jan 27, 2017
BEST ANSWER: That's a great deal of dry hopping, it's definitely going to have a rich scent. It may effect the flavor not having it in the boil, but that's the best part of home brewing is that you can try unique styles and see how it turns out!
I have got to the point where the peel is in the fermenter but due to work I may not be able to get it out for maybe 14 days rather than the 5-7 recommended, is this going to be a problem? Thanks
G E on Aug 3, 2016
BEST ANSWER: You probably will stop extracting fruity/zesty flavors from the peel, and the longer it sits, the more likely it will be to take on some mild pulpy/pithy/vegetal flavors from the peel. This could be quite mild and I find it will not ruin a beer for me, but it can make it "less awesome". So, if that is the cards dealt, you could choose to do nothing and live with the slightly different beer, or find some alternative to be able to separate the beer from the grapefruit peel. If you could have it sit on peel for less time, that might be better than too long.
How long should the peel soak in the vodka for before putting it in the secondary? Thanks
J J on Jul 20, 2016
BEST ANSWER: We recommend 2 days, since this allows ample time to sanitize the peel. Since the vodka will soak up a lot of the flavor, we also recommend adding the vodka as well.
If kegging this what should the psi be set to to force carbonate?
M R on Jul 19, 2016
BEST ANSWER: There are several ways to do this, but the fastest is 35 PSI for 2 days with the keg at 38-41 degrees F.
Is it possible to soak the grapefruit peel with another type of hard alcohol like whisky?
Brennan M on Jun 28, 2016
BEST ANSWER: Yes, you can certainly do that. Any high alcohol spirit will work well for extracting the flavors.
10 days in the primary and 3 weeks in the secondary. Gravity readings are on target. I added the dry hops and fruit peels 6 days ago. Was planning on bottling today, but noticed the airlock is now making one bubble every 10-20 seconds. If I wait beyond the directed 5-7 days on the fruit peels, will it turn bitter or should I go ahead and bottle and run the risk of "bottle bombs"?
Craig T on Jun 25, 2016
BEST ANSWER: If the gravity is unchanged, then there is no fermentation. Sometimes residual CO2 can come out of suspension and come through the airlock. This is most common if the fermentor has been moved or disturbed in any way.
Can fresh grapefruit peel be used instead of the included grapefruit?
M R on Jun 14, 2016

Thanks for your question! Yes, you can use fresh zest instead of the included stuff.

When fermentation started the I thought the temperature was ok when I checked the temp was at 78f. The fermentation exploded the first day and after a couple more days the bubbles stopped is it ok or did I ruin it.
B O on Jun 13, 2016
BEST ANSWER: It's normal for it to go a bit crazy for a short time, and then calm down to near no activity. It is a bit warm to have fermented it, it would have been better kept in the very low 70's, but I'd still finish out the process at this time, the hard work is done already. I'd go by the directed schedule, and finish it out, it may well turn out just fine after all. Cheers! -Mike W, Northern Brewer
In the process of brewing this. Accidently added all the malt once at the beginning of the boil. Has anyone did this and still had good results?
A L on May 24, 2016
BEST ANSWER: This should be fine. The brew may be darker in color, slightly less bitter, and the malt flavor may not be as 'clean'. It's almost all hop flavor so it should still turn out fine! Cheers!
I know this is off topic, but...Where did that glass in the picture come from? I wanna get me one o' them!
P O on May 24, 2016
BEST ANSWER: Not sure where it came from, we have a bunch of glassware of different types for photo use. I wish we had those to sell, they are very cool! -Mike W, Northern Brewer
Can I buy this kit with dry malt extract substituted for the Gold malt syrup? I live overseas and have to haul these on boats through hot climates, and generally tend to think that DME fares better than LME in those types of situation. I'd be curious if these types of substitutions would be possible for other kits as well. Thanks.
Brian E on Apr 11, 2016
BEST ANSWER: We can not substitute the beer kits as ordered. We post the recipes so you can easily buy the ingredients a la carte and get DME instead of the LME. Golden light DME instead of gold in this one, 0.85 pounds of dry for every pound of liquid. Cheers!
