If you don’t know even part of the name of the wine you’re looking for, don’t expect me to enthusiastically assist you in your quest. “It has a white label, and I think it starts with an M” tells me absolutely nothing. Would you expect success in any other market?? “I drove a car once and I want to buy that car but I don’t know what it was. It was black, it had four tires and I think I steered it with a wheel.” Or “I had a box of cereal six months ago in Florida and I can’t remember the name of it. It came in a box and was made from corn.”
Come on. Please, have a clue.
