Apple: Produces a sweet, fruity taste.Good mild wood
Alder: Not sure, used for fish in cooking so i would assume a very light woody flavor.
Cherry: Similar to apple
sweet and usually very fruity depending on the age of the wood. Tends to be mild
Hickory: Probably the most well known woods. VERY PUNGENT and strong.
Maple: Gives a light and sweet taste
Mesquite: Like hickory but less in your face. Intense smokey flavor but not as harsh.
Oak: Most popular. Subtle smooth rich woody flavor
Pecan: Gives somewhat of a fruity flavor
Some off my head and that i found online.
Apple, maple, or pecan would prob be best to experiment with.
Enjoy!
