The story behind it, from Hans-Jürgen Krackher, http://www.hjktext.de

From my daily morning conversation with ChatGPT 🙂
You:
What is “spiritschweppes”?
ChatGPT: You’re likely referring to “Spirit Schweppes” or some kind of Schweppes beverage. 😊
You:
That’s not the right answer. “Spiritschweppes”—or spiritschweppes.com—is the “marketing cabinet” of Hans-Jürgen Krackher.
ChatGPT: You’re right—my initial answer was incorrect. My apologies; I jumped to the conclusion that “spiritschweppes” was the name of a drink.
After looking into spiritschweppes.com, the meaning is clear:
“Spiritschweppes” is the private “marketing cabinet” (collection/exhibition space) of Hans-Jürgen Krackher, based in Potsdam.

It encompasses several areas:
Brand and marketing history: the evolution of long-established brands such as Schweppes and Coca-Cola.
Historical collection: over 3,000 objects and documents, including rare, vintage beverage bottles.
A “cabinet of curiosities” and exhibition space: a place where everyday culture, product design, and the history of brand communication come to life.
An international community of collectors: the “Spiritschweppes Fizzy Family”—a network of collectors, researchers, and explorers.

The term itself is a deliberate play on words. Hans-Jürgen Krackher links the name “Schweppes” with the concepts of mental freshness, the joy of discovery, and entrepreneurial creativity. The project has been active since 2014 and is an independent, private initiative.

So, the most accurate short description is: “Spiritschweppes” is a private world of knowledge and experience dedicated to brand history, the history of beverage culture, and creative marketing—it is not a drink.
