I realize this thread is very old, but have just gone through the process of smoking grains, and have some questions.
I am brewing an Imperial Stout, and the original plan was to smoke all of the base malt for about 30 min. I made up some SS mesh baskets, and used a friends Little Chief smoker with apple and cherry wood. I wet the grains with a spray bottle, and turned the grain every 10 min, at the 30 min mark, the grain had no noticeable smoke aroma, so I continued to wet it and smoke it for another hour and a half. The grain is now really smoky, and I am considering using it for 50% of my base malt. If I chew up a grain, it absolutely tastes like smoke. This is going to be a big assertive beer, and I don’t want the smoke to be lost, but I also don’t want a total smoke bomb.
Those of you who have smoked your own grain, how noticeable was the smoke aroma / flavor in the raw grain, how much of it did you go with in the beer, and how noticeable was it in the finished product?
I realize that predicting the results are impossible, but I just want a few “data points” to base my decision on.
