I agree in both cases. A wooden chair has is made of wood. The wood is still wood. Wine is not made of grapes but from grapes. The grapes no longer exist.

I would also say, "These shoes were made from rubber tires" just like native Taiwanese. Those shoes are not rubber tires. Thus, they are not made of rubber tires, but they were made from rubber tires.
