‘Kommerzienrat’ Weiss published advertisements like this one from 1902 boasting KESSLER Cabinet not only being made strictly according to the French method, but also as an ‘absolute alternative’ to the French Champagne. Statements like these were banned 17 years later, when in 1919 the Treaty of Versailles decreed that henceforth the term Champagne would be reserved exclusively for products from the Champagne region. Since then, sparkling wines from other countries or regions are known as Crêmant, Spumante, Cava or, in Germany, as Sekt.
