Sipster is the e-commerce extension of Zürich-based wine & food events business Uncorked GmbH, founded by Robert & Stephanie Hergenrader. Our simple goal: you leverage our experience to host the best possible event.
We started working for you on holidays...
Just for fun we spend 15 years visiting worldwide wine & food regions on holidays, inspired after meeting at university and attending Wine Appreciation class (for credit!) with Dr. Richard Vine (his real name!). Stephanie’s job transfer brings the family from Chicago to Zürich in 2007.
After 20 years climbing corporate rungs, both billion-dollar
employers make us redundant in the same year.
Don’t worry! They soon posted excellent profits again. Yet late 2012 finds us groundlessly cut adrift, double-unemployed in the world’s most expensive city, 7,000 km from home
Friends and colleagues assume we’ll head home.
Wrong, we fight!
We incorporate our hobby of teaching friends about wine in our living room: Uncorked GmbH is born and… we go pro!
We earn WSET & SWE wine certifications and under the guidance of top-notch caterers begin hosting ever bigger wine & food events.
We fine-tune how to throw easy, fantastic parties...
In Zürich’s international environment, we’re lucky to host thousands of friendly people from all over the world and all walks of life.
...and we package that experience for you!
With more party requests than Uncorked can handle, we invent a way for anyone to throw a fantastic party, big or small.
Code-named Party In A Box, we work 18 months in our “spare time” to develop, test, refine and launch Sipster.
Our management team has one goal:
that you host an easy, memorable event
