Clonebrews Samuel Smith Oatmeal Stout - SRM way off (darker in recipe)?

[Gadjobrinus]

Just looking for a confirmation or reality check. They are giving:

MO - 81.2%
Crystal 55 - 5.5%**
Chocolate malt - 5.5% (I'm using Simpson's at 413)
Flaked Oats - 5.5%
Roasted Barley - 2.2%

Using the recipe, I'm only coming up with SRM 30, whereas they're showing 68, obviously much darker. Anyone seeing something I'm not seeing?

**I'm actually using 77 at 2.2% and 135-165 at 3.4% - so my recipe should be even darker than Clonebrews).

What are the actual malts weights (not percentages) and batch size?

Also, what's the Lovibond for your roasted barley?

 

[DBhomebrew]

Are you sure you're looking at SRM vs SRM and not vs EBC?

Yep. Actually just came across this - wonder if others are getting the same issue.

5 gallons:

7.5# pale malt
.5# (toasted) flaked oatmeal
.5# British Chocolate (I'm using Simpson's - 413 L)
.5# 55L crystal
3 oz roasted barley

If I actually go with their 55L v. the darker crystals I would like to use, I'm coming up even lighter, slightly - 28.8 SRM

I think maybe you meant .2# Roasted Barley (to line up with your original percentages)? If so, 30 SRM looks about right.

Sorry, my mistake. Actually 3 oz.

No idea why they're getting 68 SRM. That 30 is too light.

 

[DBhomebrew]

Maybe the mistake is theirs and they've mistakenly said SRM when they really mean EBC? 68EBC = 35SRM

Yeah, I could see that. But even so - that's way too light for the beer, don't you think? On that thread he indicated it came out dark amber, "light porter."

eta: ... or agree on another color chart for purposes of this topic.

35's pretty dark in my book.

 

[day_trippr]

Beersmith3 says my imperial chocolate stout recipe hits 52 SRM (close to 100 EBC).
I'd be unhappy if my stout wasn't "black" - because a black stout is beautiful. Brown stout, not so much...

Cheers!

Hmm. Not in mine actually - agree with day_trippr. Not expecting the same color, but by way of comparison, my current RIS is coming in at 89 SRM (following Ron Pattinson, including the high IBUs - so letting the chips fall as he has them). I'm looking right in day_trippr's range, 100 or even a tad more. Black patent? My crystals are already as I like them for other than dry-stouts, a blend of 77 and 135-165.

While here, I have some Simpson's DRC. Not a clone any longer, but interested in using it. Anyone? Suggestions here?

 

[DBhomebrew]

Maybe it's my screen, but I don't see much difference between 69 & 138 on that (EBC) chart.

I'm seeing the brown in 69, but it isn't that dramatic, agreed. Just looking for a true black.

 

[day_trippr]

There is a subtle difference on my monitor but these things aren't all that portable to begin with...

[edit] fwiw, pasting the source image into a photo editor and picking at the dark colors for their RGB values:

Dunkel EBC 39: 80,54,33
Porter EBC 47: 39,30,29
Stout EBC 57: 23,19,16
Baltic Porter EBC 69: 16,16,16
Export Stout EBC 79: 12,12,12
Imperial Stout EBC 138: 0,0,0

Cheers!

Just looked up a few from Terry Foster's stout book, for some data points. All are in SRM:

Foreign extra, 129, 194, 224, 156
Oatmeals: 118, 94, 81, 86, 88, 79

I don't know which RIS of his you're brewing, but my 1914 Courage comes in at a calculated 71 SRM and is black, black, black.

 

[day_trippr]

You sure those aren't EBC?

SRM * 1.97 -> EBC

 

[Gadjobrinus]

I'm getting 65.5, but yeah, I agree - nicely black. I'd be happy with that.

 

[Gadjobrinus]

You mean the values I posted? Yep, just an example - his "Hurricane in Kingston" - 194 SRM:

 

[day_trippr]

Yeah, that's clearly nonsensical.
If EBC 138 (SRM 70.1 and Lovibond 52.3) registers as RGB 0,0,0 (ie: BLACK) there isn't really anything beyond that...

Cheers!

So strange. Plugging his St. Andrew's Pleasure in, I'm still only getting 40 SRM (he's getting 118, so clearly that's crazy). I have to go back to some old recipes, as none of this makes sense to me.

Edit: My old stout is 48, a robust porter is 44, and a baltic porter is 58. My old RIS is 71. It has 70% mild malt, 10.4% each of brown and DRC, 3.9% roast barley and 5.2% chocolate.
