I have 2 successful cheese smokes under my belt. I was doing batch 3 today and ran into a snag. My first 2 smokes were both 3 hours in my PID Big Chief. No electric, just my AMNTS with cherry and apple. Today I did alder but at 3 hours there was almost no color, and a quick taste had almost no smoke flavor. It ended up going about 8 hours. Just seemed kind of weird. Any idea on what might have happened? Smoker temps were 70 to 75. Weather in the 50's for all the smokes.
