All our flavored BBQ pellets are formulated to provide a mixture of 60% Oak base and 40% of the designated flavor. There two reasons for this. For one; most single species trees are too much taste of one species for the users and second and more importantly are that all wood burns at various heat output levels. Rather than have to adjust the grill for each species the user wants a consistent heat output pellet. We do make 100% species BBQ pellets for those that want to blend their own formulas.
