Vine Charcoal

The thick woody part of some healthy grape vines denuded of leaves and side shoots

cut to length for the size of the container and cooked on the coleman stove like the willow but in a smaller container and not as precisely layered, came out as beautiful charcoal.

I didn't whittle or peel the bark off but let it burn with the rest and it made fine vine charcoal.  The bark just seemed to flake off as ash on the final product.  Not even too messy.
