Rich, just one thought to share...i had also thought about using some vines for ambiance close to the winery...but i did not do it because you have to spray them to make things look tip top because THAT is where EVERYONE is going to see things up close.....if you have to spray it means two POSSIBLE things...one is you will have to deal w the REI......the second issue is drift not only onto you patio area but into the winery itself
