Adam I am sitting here trying to figure out how long I had the wood sitting out. It has been a year since this happened. I got the wood from the jobsite and took it home and cut it into roughly 4 inch lengths then used a hachet to split in to 3 or 4 pieces. I then left them on a table for a week or 2.
And yes I haven't been able to duplicate the flavor since last year. I still have a few pieces of that same tree. I use it fairly often and haven't had the taste of maple as strong as those ribs last year. That is the only thing I can attribut to the difference.
The cherry incident has been several years ago on my old ECB. I used chips at the time. I hadn't found this site yet.
Anyhow the guy that runs the whole tree chipper was on the same job as me. I saw a couple of good size cherry trees in the chip pile and asked him to move the chipper when he chiped them up to make a seperate pile. He did and he gave me a nylon bag that had grass seed in it at one time. I filled it full of chips and took it home. A couple of weeks later I took a ziploc sandwich bag and filled it with chips and water to soak them and threw them on the fire when the ribs went on. I am telling you it tasted like I basted the ribs with the juice of marchino cherrys from the store. It was awesome. I haven't been able to duplicate that since. That is what makes me think it has to do with being green.
All I can say the cherry chips left an amazing unique taste that I really liked. The maple on the other hand was nothing short of awesome. I have read all this about adding honey to BBQ sauce to make it sweeter. I haven't tried that yet. Those ribs with the maple smoke were so good that I have been thinking about getting some real maple syrup and using that instead of the honey in the recipes just trying to get some more of that flavor.
I remember reading in the forums about green wood making a bitter taste but I don't remember anything about creosote. I guess I need to do a search and get on the same page.
Edit/ I have done some searching and I can most definately say there has never been any creasote on any of my ribs. They were as sweet as if I put sugar on them. Both the cherry and maple. The only rub I have ever used before I found this site was old bay seasoning. So I know nothing sweet came from that rub.
