I'm planning on making a barley wine and I thought some smoked malt would be a fine addition to the massive flavor profile this beer will have. Found a nice thick cardboard box at work along with a cardboard tube from our last roll of giant saran wrap. First I got it sealed up real good. Had some aluminum tape leftover from when I got my AC installed 15 years ago. Sealed up and secured the smokestack. Built a little house for the HAAS to sit in. Lookin good. Needs some air inlets I think. That should help. 3 one inch wide openings. Time for a test smoke. Gotta make sure the smoke will flow and it doesn't catch fire. Went for a couple hours and nothing bad happened. Didn't hardly get warm. Now I need something to hold the grain. Found some wood and screen in the basement. It's about 13" x 14 " inside. Mounted on my racks with some tie wraps. And off to the box it goes. Get my Alder dust lit. The screen holds 1 pound of grain. Maris Otter of course. Alaskan Brewing uses Alder to smoke their grain, incidentally. We'll cover it up and see how it goes. Getting some good smoke. Hard to see in the pic. I'll let you know how it turns out.
