Episode Description

Recording from the chaos of Mardi Gras in New Orleans (sirens, bands, and floats included), Joanne breaks down why Prosecco deserved its own episode. This Italian sparkling wine produces nearly 500 million bottles annually - dwarfing both Champagne and Cava - and uses the tank method to create those fresh, fruity bubbles you know and love.

You'll discover why the grape was renamed from Prosecco to Glera in 2009, how to navigate the confusing sweetness levels where "dry" is actually sweeter than "extra dry", and what makes Conegliano Valdobbiadene so special (besides being impossible to pronounce). Joanne also introduces Col Fondo, the funky natural wine style with sediment at the bottom that Italians apparently use to make risotto.

What You'll Learn in This Episode

Prosecco Production & Tank Method Basics

• Why Prosecco dominates sparkling wine production with 486 million bottles annually
• The tank method (Charmat method) explained: how it differs from traditional method Champagne
• Tank method process: second fermentation in pressurized tanks, not bottles
• Why the tank method is faster, cheaper, and preserves fresh fruit flavors
• Tank method benefits: no lees aging means vibrant green apple, pear, and melon flavors
• Who really invented the tank method: Italian Federico Martinotti vs. Frenchman Eugène Charmat

Understanding Prosecco's Geography & Quality Levels

• The 2009 DOC creation and strategic grape renaming from Prosecco to Glera
• Prosecco DOC covers 34,000 hectares with high yields: 18 tons per hectare vs. Champagne's 10-11
• Conegliano Valdobbiadene DOCG: the premium zone so hard to pronounce it's a sobriety test
• Rive designations: 43 named crus on steep limestone slopes (50-500m elevation)
• Superiore di Asti and other top vineyard areas within the DOCG

Prosecco Grapes & Styles

• Glera: the primary Prosecco grape (formerly called Prosecco)
• Permitted additions: up to 15% Chardonnay, Pinot Bianco, or Pinot Grigio for body and alcohol
• Rosé Prosecco (legal since 2020) with up to 15% Pinot Noir
• Col Fondo "sui lieviti" style: pétillant naturel method with sediment in bottle

The Confusing Prosecco Sweetness Levels

• Brut: the driest Prosecco style
• Extra Dry: 12-17 g/L residual sugar (the most common style - not actually dry!)
• Dry: 17-32 g/L residual sugar (confusingly sweeter than "Extra Dry")
• Why Prosecco sweetness levels can range from dry to medium-sweet
