Thomas Diehl, Weingut Diehl: From Rocket Intern to Third-Generation Winemaker
About this episode
From the fast-paced startup environment at Rocket Internet back to the vineyards of the Palatinate – Thomas Diehl has taken an unusual career path. As a third-generation winemaker, he took over his parents' family winery in 2019, deliberately trading a potential "Rocket career" for the tradition of winemaking.
The Journey from University to Family Business
After studying at Zeppelin University, Thomas gained valuable experience as an intern at Rocket Internet and the associated consultancy RCKT in Berlin. This period had a lasting impact on him and gave him insights into the startup and consulting world that he would later bring to the traditional family winery.
However, the decision to take over the succession of his parents' winery in 2019 was anything but straightforward. As with many family businesses, fundamental questions arose: How does the transition between generations work? What visions and ideas clash with each other?
Challenges of Business Succession
Taking over a family business brings unique challenges that differ significantly from founding a new company. Thomas Diehl provides honest insights into this complex phase in the podcast:
- –Generational conflicts: Different ideas between parents and successor about the future of the company
- –Established structures: The winery already had existing processes and traditions that couldn't simply be changed overnight
- –Initial difficulties: Not everything ran smoothly after the takeover – a normal part of the transition that required patience and adaptability
Startup Methods in Traditional Winemaking
Particularly fascinating is how Thomas brought his experiences from his time at RCKT in Berlin into the traditional wine business. The startup mentality and consulting methods he learned there could be surprisingly well applied to a centuries-old craft.
Digitalization, modern marketing approaches, and structured methodologies from the consulting world can create valuable added value even in traditional industries like winemaking. Thomas shows that innovation and tradition don't have to be mutually exclusive.
Authentic Founder Story Beyond Silicon Valley
Thomas Diehl's story is an example of how entrepreneurship can take many forms. While many founder stories revolve around tech startups and exponential growth rates, his path shows a different reality: the conscious decision for continuity, family, and regional roots.
His experiences offer valuable lessons for other successors in family businesses, but also for founders considering how to successfully connect different worlds – innovation and tradition.
Weingut Diehl Today
Weingut Diehl today represents the successful combination of tradition and modernity. Thomas has managed to preserve his family's values and craftsmanship while setting new impulses.
His story shows: Sometimes the most promising path doesn't lead forward, but back to one's own roots – though with the knowledge and experience gained along the way.
