Hello fellow brewers! I've been reading these forums for a while now and this is my first post.
I've been brewing my own beer for about a year now and I'm in the process of transitioning from kit brewing to an all grain process. I've always been a DIY sort of person because for one, it's cheaper and secondly, the satisfaction you get from something you built yourself always make the final result so much better.
Anyway, to the point. I've been roasting my own coffee for years and built my own drum for roasting coffee about 5-6 years ago. When I realized what a great product it was I decided to see if I could sell a few. Long story short...It was a huge hit! I'm not sure if any of you have heard of it but it was called a Buzzroaster. Well, I got an email from a few homebrewers that were interested in using it for grain roasting. Being a homebrewer this was the ultimate "DUH" moment! Of course! Why hadn't I thought of that earlier!
The current design would not work due to the size of the holes in the drum, the grain would fall right through. So I built a prototype with smaller holes and tried to roast a batch of 2 row malt in an attempt to create a deep amber malt. My first attempt was a little over roasted, more of a brown malt but was still usable. One thing I noticed was it was very evenly roasted and roasted much quicker than I thought it would. I used Barleypopmaker's roasting blog as a guide and had to adjust the time and monitor the temps a little more closely. The second attempt was spot on and came out perfectly.
The ultimate DUH moment turned out to be the ultimate EUREKA moment! If there is sufficient interest in a roaster like this I may start selling these.
