Default Chocolate Oatmeal Stout

Well I cracked open a new brew. Inicially I called it an Ale... not sure if its a Stout.... someone here I'm sure could direct me there. Heres a pic



Ouside of absolutly no head, this is real good (so far only carbonated for 11 days as well). You take a sip and at first you dont taste any chocolate. None whatsover. Then you sit there for a moment, lick your lips and PRESTO! A real nice lingering chocolate taste!

As you know I'm playing with Promash and here is what it spits out for me.

The lack of head might be from the oils in the chocolate. I did a chocolate stout last winter where I boiled 3oz of bittersweet for the full 60 minutes to really isomerize the oils and it seemed to work. I kegged the beer and it had fantastic head despite all the horror stories I had heard about using real chocolate. I should note that you should definitely not use any kind of milk chocolate, only the dark varieties.

Or maybe it just needs more conditioning or there was some soap residue on your glass...

I thought about the soap. Really washed the glass out. It's only been conditioning for 11 days though like you said. Carbonation lasted for roughly 25 minutes. I got a full two cases of this stuff, so it'll have it's time to age. I was shooting for about 4% Alc... got 2.33. The taste of the chocolate is real mellow and lingers a bit. I wonder if it would have even come out with too much more Alc....

What is the difference?... not the chocolate, but what is the difference between the two in a beer recipe?

seems really odd to me that with nearly 6lbs of extract in there, you only get 3% ABV...
out of curiosity, what brand of extract did you use?

Don't know if I'm following the question, but milk chocolate has milk solids in it which are more difficult to isomerize. I imagine it would work if you boil long enough, but it will also result in a sweeter final product. I would stick with the semi- and bittersweet chocolate which only has enough fat added to 'stick' it together. Apparently cocoa powder works well, also, and has no oils at all. I've also heard of people 'dryhopping' with the cocoa nibs which seems to work perhaps better than any other method, but the nibs are fairly expensive.

So If you went with cocoa powder instead, would you use the same 6ozs? Or go with more/less?

I believe I used Multon's DME. I dont think I did the Flacked Oats right though. I just steeped them with the grain and I think some people here said that they needed to be mashed. That could have screwed up some numbers.

Lou, you should also know that this fermentation was VERY FAST. It was very fast with the starter too. So fast that I thought I had a stuck fermentation and repitched the yeast. Nothing happened though.... temp was edging on the low side... around 68 (although I was trying to warm it up a bit to be on the safe side). From secondary to bottling the gravity did not change at all as well and I was VERY lazy with bottling this as you see.

Not sure.
