"Das is ein Unicum!" said Emperor Joseph II, and the rest is history. The emperor, who was suffering from stomach problems, sought the help of Dr Zwack, who created the drink that has enjoyed unbroken popularity ever since. Now, the founder's descendant, Sándor Zwack, personally guides us through the family's past, a piece of history, at the company's headquarters. You can also ask about The Secret. Sándor is hosting a party of 15, with delicious snacks and even more delicious drinks. After a private cellar visit and museum tour, you will be invited to Peter Zwack's former office, which is an exceptional honour to enter, as the family has kept it closed since his death.
