The quality of light can be summed up in three fundamental characteristics -- color, brightness and contrast. The softness or hardness of light is related to the amount of contrast. Soft light produces soft shadows (shadows not well defined) and hard light produces harsh shadows (well defined shadows). Note that the softness and hardness of light has nothing to do with the color or brightness of light.
Depending on the material the subject is made of, soft and hard light may produce relatively the same highlights or very different highlights. As a reminder, soft and hard light will always produce very different shadows.
There are two ways to produce soft light: Either use a relatively small light source and disperse its rays of light in different directions or use a relatively large light source.
In this case, the top of the bottle is made of two fundamentally different materials -- foil and paper. The light source was relatively large. That combination of light and subject material produced a soft highlight on the foil and no highlight on the paper.
So, that brings us back to the fact that the light at the top of the bottle is most definitely very soft.
There are two reasons I'm making such a big deal of making sure you understand the importance of using photographers' definitions and terminology when describing light. The first reason is that doing so will help you immensely in your quest to accurately assess the quality of light in your landscape photography, actually, all styles of photography. Once you've accurately assessed the quality of light, you will be far closer to accurately assessing whether the photograph will appear as you hope.
The second reason is that using terminology inaccurately impedes your progress through the learning curve; though you know what you are trying to communicate with others, informed photographers have no realistic choice but to assume you are using the terminology accurately even though that may not be the case.
Moral of the story: Read and reread pages 13 -23 of Light: Science and Photography and apply the concepts to scenes that you photograph until everything sinks in. I just now read parts of those pages for at least the 10th time just to make sure this post doesn't accidentally mislead you by using terminology inaccurately.
