This product is an example of architectural visualization. The scene contains all of the models required to create a still image of a high end kitchen installation. It uses mostly procedural textures to shade its geometry. Procedural textures are ideal for doing things like the granite worktops. It is a great example of how to get started creating things like glass. You could borrow the shader setup for the glass bottles and apply them to your own projects.
There are many shaders and models in this scene file that could be extracted and imported into your own projects.
