"He loves wine."

Translation: On kocha wino.

[Vasily16]

Is it possible to use kochać about objects and not about people?

[Vengir]

Just as silmeth said, although I personally would rather use "uwielbiać".

[silmeth]

Yes. In a similar manner as in English. If someone loves (kocha) something, it just means that he likes and enjoys it very much.
