Product Details
Just like grandma used to do, stash some of this delicious treat out of view and hoard it for yourself. The intoxicating aromas and flavors of freshly baked oatmeal raisin cookies is surely a fond memory, and now that we are all grown up, why not craft a stout to reminisce? Pleasant, subtle aromas and flavors of raisin, cinnamon and vanilla engage with the velvety body of a traditional oatmeal stout to create an immensely pleasing and highly elaborate sipping experience.


Slightly roasty nose with no hop aroma. Scents of vanilla, cinnamon and raisins are prominent.


Nearly jet black in color with deep garnet and ruby highlights, good clarity. Firm and persistent khaki-tan head forms easily and laces down the glass well.


Clean malt background flavors with a faint nutty and biscuity character are layered with a slightly chocolaty and roasty flavor. Moderate-low hop bitterness. Clean fermentation with subtle fruity esters. Flavors of cinnamon, raisin and vanilla persist in the finish.


Medium body with moderate carbonation. Low alcohol warmth with smooth creaminess and no astringency.

Overall Impression    

A complexly flavored stout with surprising flavors of freshly baked oatmeal raisin cookies.

Brewed this beer 2 times. Winner cookie dinner! I shared this with the work crew. Huge success - Loved it! I will make this again. Thanks for all the tips out there. Very Helpful!

Careful with the rum
I must have added too much dark rum (I used Kraken - mistake), since the taste was not subtle. No real raisin or vanilla taste. I didn't think I added much more than the recipe required, but maybe I did. I put in the rum from soaking the raisins, but I wouldn't in retrospect.

Top 3 ever
Been Brewing now for getting close to 10 years and this one is top notch. I was actually thinking about stopping b/c last 2 brews were too similar and just bland. The one saved me. I had family in town for the begging and they loved it too. One friend said tastes like a cinnamon bagel with a hint of rum in the end. Followed the recipe for the most part but added more ozs of rum and cinnamon. Man, this one rocks and a must dry. Black as night and very smooth.

Grandma's Dirty Little Secrets
I was totally surprised and enthralled when I started brewing this kit to find how unique it was. I have brewed dozens of kits and a few of my own recipes, but this is the first time I have used rum soaked raisins, vanilla beans, and cinnamon. It is still brewing and I am anxiously awaiting the opportunity to taste the finished product.

There are much Better Stouts to try than this one.
I've brewed quite a bit of beer over the years. This is one of the worst ones I ever had. Even clearing in the secondary, there was so much more sediment than usual...mostly the starchy oats. The flavor is very unusual, and to me, unlikable. Best way I can describe it: It's like someone put out a lit cigar in my glass of beer. I would never do this one again.

The only thing I can say is that the stout turned out really light in color more like a dark Amber beer and not black like the pics shown I followed the recipe word for word so not sure why it didn't. Will be bottling soon and hope to have a good product in the end just puzzled on the lightness of the brew

Just ok
I kept waiting for something from this beer. Nothing really special about it. Nothing stands out. Not sure where the cinnamon is. I would not get this again.

High Hopes Dashed
I bought this kit twice because it sounded so good. I admit on the first kit I screwed up and didn't steep the grains correctly so I bought another one. I followed the instructions perfectly, even bought the liquid yeast to ensure a great beer and my hopes were dashed when I tasted it. I never throw out beer and I think I will choke this one down but it is a bit sour for a stout. I have bought many kits from northern brewer and have loved them all but I caution future buyers of this kit. I was disappointed but I will continue to get kits from this great company!

After dozens of successful brews (mostly from Northern Brewer) we finally ran into a dud with this one. Doesn't have the color of the beer pictured and is really blah on taste. We're going to attempt to put more rum/vanilla in it, as you can't taste any subtle flavors at all. Will not be buying this one again.

What is the projected FG of this beer?
A shopper on Oct 21, 2017
BEST ANSWER: I brewed the extract version of this in August 2016. My OG was 1.050 which was lower than expected, but the grains were very tightly packed and I don't believe the water was freely able to circulate through. My FG was 1.012 after two weeks for an abv of 5.0%. Was quite enjoyable.
I have to admit, I'm not much of a rum drinker so I'm completely at a loss as to what kind of "dark rum" I should be picking up for this. Does anyone have any suggestions that won't break my wallet? I imagine that going with a spiced rum would be a bad idea, so I guess I'm looking for a good flavored dark one. Any help or advice would be appreciated, thanks!
M C on Apr 21, 2016
BEST ANSWER: $13.00 for Myers's original dark rum
I see the raisins are dumped into the pot during the last 5 min or so of the boil. Doesn't seem enough time to get full flavor out of them. Are we supposed to move the raisins over to the fermenter bucket or dispose of them after the boil?
Todd S on Apr 17, 2016
BEST ANSWER: As the instructions are written, I don't think it's intended to move them to the fermenter; but if they were contained in a small mesh bag or similar way you could surely toss them into the fermenter if desired, to get more flavor out of them. Be careful handling it, it must remain sterile if it's going into the fermenter. -Mike W, Northern Brewer
Not very knowledgeable on Rums. Do you know if a Gold or Spiced would work as well or better? I went out to two different stores and could only find those two types. I would look harder if you thought the Dark was really the best investment for this six week project.
Todd S on Apr 13, 2016
BEST ANSWER: I would say go with the gold rum and stay away from the spiced. What I believe we are looking for is strong rum flavor as that is what dark rum (aged) gives off. I was able to get Zaya Grand Reserva from my local liquor store but they tend to have almost everything. I tried looking at the grocery store but they didn't have any dark rum. I still have a little over a week left of fermentation so I don't know how the final product will turn out but it smells delicious. To reiterate stir clear of the spiced rum and go with a good quality gold rum if you can't get dark. Hope this helps! Cheers & 17
When do you think this will be back in stock?
A shopper on Dec 8, 2017
BEST ANSWER: At this time, we do not have plans to restock this kit due to issues with vanilla crops. Sorry for any inconvenience! Cheer!
How much cinnamon do you use in the Secondary fermentation with the vanilla beans ?
W H on May 2, 2016
BEST ANSWER: 1 ounce of cinnamon is included in this kit. Cheers!
Is black rum the same as dark rum? And what dark rum do you recommend? I see you said you used 100 proof captain for pilot batch, but captain isn't a dark run but it is spiced rum, so kind of confusing.
James J on Apr 24, 2016

Thank you for you question. I would probably go with something like the Kraken myself.

What is the target OG? And how will the rum effect it?
L A on Apr 11, 2016
BEST ANSWER: A: The OG should be near 1.065; and the rum added to the fermenter late in the secondary will add alcohol, of course, and flavor, but it won't raise the FG, but lower it some, due to the higher alcohol content than the beer has. The rum addition will not affect the overall ABV much, though, in a 5-gallon batch, it just bumps it up slightly. -Mike W, Northern Brewer

From customer Jim Clark:

The instructions indicate that the OG should be 1.065. Mine was observed at 1.057, which I believe is more on target. if you use the formula 6.3 lbs of LME *.0076 + 1 lb DME at .0084 yields an OG of 1 + .056. As for the rum, if it is added to the original fermenter, it will decrease the original gravity as the specific gravity of dark rum is .something like .952, but in such small amounts this should be pretty negligible. Assuming normal fermentation one would expect the final gravity to be lower, so the AVB would be ever so slightly higher???
Had a couple of questions regarding this brew, after soaking the raisins, vanilla and cinnamon into the rum, do we dump the rum into the beer as well or just the items themselves?
B H on Apr 1, 2016
BEST ANSWER: Yes, you would dump the rum into the beer as well.
