I made 2 butts for the first time Saturday night. I used a mixture of 3 Oak wood chunks,1 Mesquite chunk, 7 small Cherry wood chunks and 3 handful of Apple wood chips. After bbqing for 18 hours, the meat did not have any smoke taste whatsoever. Why is that? It had a nice smoke ring but lacked that flavor. I did notice in the beginning (first 2-3 hours) there was a lot of smoke and afterwards, no smoke coming out at all. I even tried to wrap the wood chunks in foil paper to slow down the smoking. I was worried that I might be oversmoking the meat and did not want a bitter taste so I didn't add more wood. The opposite occurred. Any advice would be appreciated.
