Is my maple syrup still good?
Your syrup is perfectly safe. People will argue about whether it's necessary to store maple syrup in the refrigerator in general. Regardless of your feelings about that, it's a fact that many people don't refrigerate it at all, ever, with no discernible ill effect. Certainly, 7 hours or even 7 days at room temperature will do you no harm at all. Maple syrup has a fairly low concentration of water, so few organisms are able to grow in or on it. And those that do grow very slowly.

Enjoy your syrup.
