If you have ever wondered why this narrow strip of land on the French-German border produces such distinctive wines, this episode answers that question in full. The Vosges Mountains turn out to be the key to everything. Joanne explains the rain shadow effect in detail, walking through how Atlantic moisture gets dumped on the western slopes while the vineyards on the eastern foothills enjoy some of the driest and sunniest growing conditions in all of France. That combination of continental climate and natural shelter is what makes Alsace capable of producing wines of genuine depth and complexity from aromatic white varieties. Joanne also makes the case, clearly and without hesitation, that the white wines of Alsace belong in the conversation about the greatest wines in the world. If you are a WSET Level 2 or Level 3 student this episode covers material that is directly relevant to your exam, and Joanne breaks it down in a way that makes it genuinely stick. What You'll Learn in This Episode The Rain Shadow Effect and Why It Matters How Atlantic winds carry moisture from the west and drop it on the western side of the Vosges Mountains Why the eastern foothills receive only around 500mm of rainfall annually compared to up to 2,000mm on the western side Why this dry, sunny microclimate is what makes Alsace wines possible at this northern latitude The Grape Varieties of Alsace Riesling - the dominant grape, medium to full body, typically dry, high acidity, citrus and stone fruit with a stony mineral character Gewurztraminer - pungent, aromatic, spicy nose with lychee, rose, and sweet baking spices, full bodied with rich oily texture and high alcohol Pinot Gris - rich, full bodied, high alcohol, pronounced flavour intensity with fresh and dried fruit and a honeyed character Muscat - light to medium bodied, orange blossom, rose, and fresh grape aromas, and why Muscat Ottonel is more widely planted than Muscat Blanc a Petits Grains despite being less aromatic Pinot Blanc - planted on the plains and the key grape for Cremant d'Alsace Pinot Noir - the only red grape, less than 10% of total plantings The Appellation System Alsace AOC as the regional appellation covering the majority of production Why grape varieties are labelled on Alsace wines and the 100% rule that applies <li class="whitespace-normal b
