the bottle was put outside and declared hefker, available for anyone to take. 

As I got closer, I assumed hefker but thought it strange that someone had old shmitta wine from 6 years ago now that needed to be made hefhker.

When I got close enough to the bottle, I saw that the original owner put a note on the bottle saying it is hefker with the explanation that there is nothing wrong with the wine but the bottle was near chametz.

ok
