Tomas Voltz has written/published more than a dozen books, the last ones also as an app and internet presence (which during their 15 years of existence contributed to a major change in the Swiss medical market). Other books (in German): "Dialoge mit Sokrates" and "Mut zur Kritik".

Having moved from Switzerland to Spain in 1998, «one day, driving through the Penedés region and discovering so many amazing wineries I had never heard of, I researched and found out, that international tourists had almost no way to find information about most of these wineries and how to visit them. Especially the smaller and medium sized ones. The same was true for most other areas of wine production in Spain. After further research and an extensive survey among 250 wineries in Catalunya, I started to develop Wine.Pop which lists more than 3.000 wineries globally.

While WinePop itself is currently undergoing a major overhaul, I discovered that there is another important factor missing for a rich experience for wine lovers: An international guide to hundreds of wonderful wine cities all over Europe, big and small, which have a rich cultural heritage. Visiting wineries is not enough, you just have to experience the surrounding culture, the nature, the history, the people, their culinary specialities, their festivities and more. Visiting the villages and cities associated with the wineries can be an amazingly enjoyable experience, yes even an adventure. And so we are now presenting WineCities and invite wine travellers to join our community, share their experiences of their travels, ask others questions, find new friends and enrich each others lives as lovers of wine and its fine culture.»
