This is straight from the Brewpaks guide to malt. I did it and posted some comments on this forum. After some 4-6 weeks it tasted awful, like trying to drink a smoky bacon sandwich without any HP sauce on it.An interesting usage is to blend Rauchmalz with Special B (60/40) to emulate the flavour of the traditional English brown malt, traditionally kilned over open fires.
I tried another bottle during the week- 6 months later- and it's gorgeous. The smoke is just discernible and the whole thing has come together to make a lovely rich brown ale. Well worth doing, but it needs a long maturation on the bottle.
