Episode Description
This week Joanne picks up where Episode 106 left off and dives deep into the grapes, climate, and appellation structure of Alsace. 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 • Blended wines - Edelzwicker, Gentil, and producer-labelled blends • Alsace Grand Cru AOC - the 51 grand cru sites, the rules, and the controversy over boundaries • Vendanges Tardives - late harvest, minimum sugar ripeness, passerillage, and how it compares to German Spatlese and Auslese • Selection de Grains Nobles - the sweetest category, noble rot, and its German equivalent
Winemaking in Alsace
• Why aromatic winemaking means oxygen is the enemy at every step • The use of stainless steel and inert vessels to preserve primary aromatics • Why MLF and extended lees ageing are avoided • The role of large old oak barrels - why they impart no flavour but allow tiny amounts of oxygen to round out the texture • The 2021 sweetness labelling law and why implementation has been uneven
Episode Highlights and Quotes
"If you give me that MW essay question about whether white wine can be as great as red wine, I am going to focus a lot on Alsace."
"Gewurztraminer jumps out of the glass at you in a blind tasting. Your textbook uses the word pungent, which I find hilarious."
"These large old oak barrels, some of them are a hundred plus years old. Any…
