Color calculation

[Piruz]

Hi! Im trying to clone Hardywood Gingerbread Stout, and while I have been using Brewersfriend calculator and adding ingredients in EBC color (because Europe), I add only 100g (3.5 oz) of Roasted Barley (1600 EBC) and 100g Chocolate malt (3.5 oz, 1180 EBC), for 9 liter (2.5 gallon) batch with 3.4 kg (7.5 lb) of lighter malts, I get over 40 SRM wort?

How everyone gets 40-50 SRM wort with 1 pound of roasted and chocolate malt (0.9kg together) in 5 gallon batches (19 liters) when if I half the amounts to my recipe, calculator says color is above 60 SRM?

Sorry for my bad english, here's the recipe (in kg and %...) :

Pale Ale 5 EBC 3 kg 78.9%
Crystal 178 EBC 0.2 kg 5.3%
Flaked oats 2 EBC 0.2 kg 5.3%
Chocolate 1180 EBC 0.1 kg 2.6%
Roasted 1600 EBC 0.1 kg 2.6%
Honey 0.2 kg 5.3%

Any suggestions am I calculating something wrong here..?

Target SRM is 40.

In my experience the SRM estimate should always be taken with a grain of salt whatever calculator you're using, especially at the upper end of the spectrum. I'm not even sure you can adjust the EBC or L levels of the ingredients in Brewer's friend, can you? You just have to pick from their standard list? So right there it could be a little off. At any rate, once it gets above about 30 SRM I think it's pretty hard to tell a difference, and with a stout I'd be more worried if it was coming out too light. You do look pretty low on the dark roasted grains, I'd worry more about correct percentages and ignore the SRM.

You can adjust colors. Or add new ingredient and input color, potential extract, and name and type of ingredient. I did that, and used EBC specs. Im on same impression that my grain bill is low on dark malts, but not sure how much is too much? Im not a fan of bitter/burnt taste, so want that to be little and more about coffee and chocolate nodes.

I'd say most stouts are in the 8-12% range for dark roasted malts, so IMO you're definitely low at about 5%. You might try making up some of it with lighter roasted malts like pale chocolate or coffee malt if you're worried about too much roast.

Bru'n Water has a good color calculator. You can manually enter the color as EBC or SRM for each of the grains used.
