Mash Colour

[danestead]

Hi All,

I'm a long time lurker and have been using the recipe database for a few years but don't really get on the forum here.

I've just noticed in Promash that when I add a recipe at lets say 70% efficiency, and then adjust it up to the 82% which I usually get, the beer colour or EBC decreases.

Anyone care to explain the theory behind that?

Cheers,
Dane.

You are in effect diluting the colour when you get higher efficiency. Dark grains dont add to sugar levels like base malts do. So the proportions change as you get more sugars exctracted from the light base malts. To keep the same EBC with greater mash eff you should end up with a high %alc beer

Ok great, thanks for the response. That makes sense.

Does it?

If you keep the volume the same, but extract 12% more sugaz, you're getting 12% more base malt sugaz from a 5 EBC grain...

...it'll be darker. Or at the very least the same.

By your logic, if I dip the grain in for only 12 minutes and get 23% efficiency ... my beer will be super dark.
