How to display products without selling them (or using the typical ecommerce modules)?
The easiest way to achieve this without using "commerce" modules are taxonomy and vocabularies, using the Entity Reference Module.

A  simple workflow to achieve this would be:

1).Create the corresponding Vocabulary with the desired term structure from admin/structure/taxonomy/add, for example:


Wine

Red



Brand #1  etc.




2). Create The Content Type with the desired Fields

3). In the content type, add an "Entity Reference" Field, assigning it to the vocabulary

4). Create your products (Add content)

5). Create Views to customize the display of each page depending on the term level (using filters)
