Ravel, if the foil was tight, it's your wood. No problem with cutting your own, but it takes several months (or more) for it to cure enough to smoke. I'm sure you know to never use "green" wood. I would cut some of those branches, and store them in a garage or somewhere with good airflow around them. Leave them to season, and order some good wood for the interim.
I haven't tried white wine in a brine, but have thought it might be good. Give it a try and let us know what you think!
