April 1100: Schloss Johannisberg, Germany, was established during this time. In 1720, when the whole estate was planted with a Riesling type of grapes, Schloss Johannisberg made history by becoming the world’s first closed Riesling vineyard. In addition, the estate claims they were the first to manufacture Spatlese in 1775, and Eiswein in 1858.
April 1863: The phylloxera epidemic occurred in France after migrating from North America on leaf cuttings in the 1850s. The issue quickly becomes widespread across the continent. The phylloxera pest, a microscopic yellow louse carried to Europe via American native vines by botanists working in the Victorian era, was responsible for destroying Europe’s vineyards.

April 1993: The process of DNA profiling for wine was innovated. Winemakers have previously either used commercial yeast to ferment grapes or hoped that native yeast would suffice. However, what happened next was unknown. Today, analysis of DNA allows winemakers to examine yeast strains in real time during the fermentation process, allowing them to better understand when fermentation is going well or poorly. Winemakers can use testing for spoilage yeast and bacteria to make better judgments during ageing and bottling.
April 1994: In this month, the Concours Mondial de Bruxelles was introduced. Since its start in 1994, the Concours Mondial de Bruxelles has been an annual international wine competition.
