I'm planning to make a stout and so I bought some roast barley at the weekend.
I will probably have some left over -- could I safely use a small amount roast barley in a "dark lager" recipe, just for coloring mainly.
You probably could as long as it wasn't a lot. I did a black lager using chocolat and black patent grains. I just used roasted barley in an amber and it didn't darken it much but I think it adds a little bite.
It is better to remain silent and be thought a fool, then to speak and remove all doubt.
