Chocolate Malt Grain Not Exactly Chocolate Beer
So maybe you’re like us and thought that chocolate malt grain might lend your home brew an intensely sweet chocolate taste … something you could enjoy both for the ABV’s and to calm that sweet tooth. Well, that’s not exactly the case, and too much dark roasted malt can really overpower your brew.
On our recent Chocolate Irish Stout, we adapted an existing recipe for traditional Irish Stout to include 1/2 lb of chocolate malt grain, in the hopes of imparting a subtle sweetness to the beer. The original recipe only called for black patent, English 2-row pale, English crystal and roasted barley. We thought we were being very clever and certainly bound for home brew greatness by crafting a perfectly blended chocolate beer. The end product wasn’t exactly what we had hoped for. The ABV was low for a number of reasons and the flavor came out burnt and a bit overpowering. Not silky sweet at all! Rather than sulk with our weak 3.12% ABV stout, we looked into the grains used in the recipe and came up with a few reasons why the final flavor came out burnt.
TOO MUCH ROASTED GRAINS
The gang at Brew-Dudes.com offer an excellent overview of the specialty chocolate malt grain, describing the flavor profile as more nutty and roasted than sweet. This could lend richness to a stout or porter, though I am not sure the effect on a pale ale or lager. Some brewers over at HomeBrewTalk.com have complained about the difficulty in using this grain, though I imagine this is more in part to my novice experience than the grain’s fault (oh, I can’t be mad at you, chocolate malt!). The related grain, Black Patent Malt, is similar but roasted longer and at higher temperatures. This can impart a smokey or even burnt flavor on your beer. I think our mistake here was adding chocolate malt grain to a recipe that already included Black Patent Malt as a dominant flavor driver. I believe this overpowering of dual dark roasted malts took over the beer — rather hijacked the beer — and gave the “burnt” taste in the final faux-Chocolate Irish Stout.
CHOCOLATE BEER ON THE FUTURE DOCKET
So, how do you brew the elusive chocolate beer? That will be an adventure for another time, friends, though I am optimistic after trying a few retail chocolate stouts. A submitted recipe for “Chocolate Ale” was well received over at HomeBrewTalk.com, which might make its way to the summer docket for home brewing. The recipe calls for adding unsweetened cocoa directly into the mash during boil, which could be interesting. If anyone has advice on a chocolate beer, be it stout or ale, please share the good word.

I recently brewed a fairly successful Sweet Chocolate Stout using extract using almost twice the chocolate malt you did and it’s not overly roasty.
Here are my ingredients:
Steep 200g Roasted Barley + 300g Dark Crystal + 400g Chocolate Malt at 65degC for 30 min.
Add 3.6kg light malt extract and boil for 90 mins total.
40g Fuggles @ 60min
10g Hallertauer Aroma @ 15min
20g Cocoa Powder @ 15min
5g Irish Moss @ 10min
20L into the fermenter
Rehydrated Safale S-04
OG 1.053, FG 1.016
Probably the tastiest brew I’ve made to date but I’ve only been brewing for just over half a year so take that as you will!

Thanks for sharing your recipe, Damian. We’ve only been at this 2 years ourselves and by no means experts.
You’ve got Dark Crystal in yours compared with the Black Patent malt in my recipe, not sure if that makes a difference. And I see you added 20g of Cocoa Powder directly into the boil — that’s great — did it just dissolve into the wort? Did that lend a sweetness or noticeable chocolate taste?
Thanks for sharing brewing tips from New Zealand.

I was trying to clone a Young’s Double Chocolate Stout but when I tried them side-by-side the Young’s one was far, far, more chocolatey. I suspect they’re using some kind of chocolate essence. I’ve never brewed with Chocolate Malt or Cocoa before and so don’t know which contributed the chocolate flavour. The Cocoa dissolved in no problem and doesn’t seem to have affected the head retention as I had feared (the lipids or something).
I brewed my first all grain this weekend and so will perhaps try the same recipe again to see what difference all grain makes and then perhaps try it again but with greater quantities of Cocoa (100g??) or Chocolate Malt.

The chocolate stout recipes I found online typically call for 1/2 to 3/4 cup (sorry, we don’t use the metric system) of unsweetened cocoa. I think the sweetened kind is what might contain oil (the lipids you reference) and start causing problems in the wort.
I found a post on the Home Brew Talk forums about some brewers trying to clone a Young’s Double Chocolate (which I’ve actually never tasted but really need to) — http://www.homebrewtalk.com/f12/youngs-double-chocolate-stout-20742/.
Good luck with the all grain adventure. Definitely more of a time commitment. If you need help building your mash, we had success with ours and posted a How-To guide (http://www.drinkhomebrew.com/how-to-guides-4/building-a-lauter-mash-tun-using-a-picnic-cooler/).
Thanks for sharing!

Yes, I found your mash tun guide very useful. My picnic cooler (we call them ‘chilly bins’ here in NZ) doesn’t have a drain hole and so I had to drill it out and I ended making the manifold only two bars and out of copper but basically copied the rest. Very useful, thanks!
I intend to post photos at some stage of my setup but I’m a pretty lazy blogger so don’t hold your breath.
