I have a vineyard and this winter I tried using prunings from my grapevines to smoke. Works nice, a lighter smoke flavor I would compare to apple wood. Orchards and vineyards prune the vines and trees each year and I imagine they would give you all you want. I will have a pickup load or more of grape prunings I'll be happy to give away. I'm in Western Wi., contact me if you want some or all.
