I usually buy bags of my wood chips, so I honestly couldn't tell you what kind of Maple it was. I think you can use just a bout any kind of wood, it is just the flavors that it imparts. Some people claim hickory or mesquite is to harsh on certain meats, myslef I prefer them. Whenever I've used cherry, it always seems to be sweeter.
careful on start this hobby, you will spend a lot of time trying out different recipes and eating way too much!
