This is a fairly complex theme, good for a fairly big and complex e-commerce site.
It has the Visual Composer Plugin, but it's not working properly (elements appearing in some session, disappearing in others…?).
A lot of graphic is not made with Visual Composer, but through coding or widgets. Changing background color and titles style need the code to be manually changed, just to make one example.
All wine presentation pages/tab design are not changeable via Visual Composer, but only working on code.
The overall impression is that this theme was made by coders for coders and then they just added Visual Composer Plugin to attract no-code-designers.
It was not designer around Visual Designer possibilities/tools. Maybe it was impossibile, I don't know…
It is definitely NOT a theme for beginners or "Photoshop-Illustrator-Indesign people": to customize a page you will need hours and you will still need a WordPress developer to finish the job.
If you just need a few pages site with the usual minimum pages (about, contacts, products and the like) this is not the theme for you: it would be like buying the power and complexity of an aircraft carrier to deliver a bread bag.
If you need to create a rich, complex site and you know how to code, then this theme is a good choice, I think.
