Episode Description

Moscato d'Asti is one of the most misunderstood classic wine styles. This lightly sweet, gently sparkling, low alcohol wine from Piedmont deserves better than its dismissive reputation. When you taste a good example, you understand just how glorious it can be.

This episode covers the Asti method, a production technique that's completely different from both the traditional method and the tank method. You'll learn why Canelli is considered the cradle of Moscato, how the Asti method works (think of it as a one pot wonder), and what makes Muscat Blanc a Petits Grains such an important grape historically. Joanne also covers the difference between Asti and Moscato d'Asti, and why this wine is perfect for brunch or late morning sipping.

What You'll Learn in This Episode

Moscato d'Asti Geography and History

• Moscato d'Asti DOCG location in northwestern Piedmont
• Provinces of Asti, Cuneo, and Alessandria with 9,700 hectares planted
• 7,000 hectares on slopes (better quality grapes)
• 52 communes and 4,000 growers with average vineyard size of 2.45 hectares
• Canelli as the cradle of Moscato, first made in 1865

The Muscat Grape Family

• Moscato is the Italian name for Muscat
• One of Italy's most planted white varieties
• Muscat Blanc a Petits Grains is the specific type used for Asti (minimum 97%)
• One of the first grapes to be recognized, grown in the Mediterranean for centuries
• Known as "the grape of the bees" dating back to Pliny the Elder
• Makes everything from light sweet sparkling to dry wines to fortified styles
• Alcohol range from 6% to 20% depending on style

The Asti Method Explained

• Juice is chilled and stored until needed (keeps wine fresh)
• Fermentation begins in tank with CO2 allowed to escape initially
• Tank is sealed and fermentation continues, trapping CO2
• Wine is chilled when it reaches about 7% alcohol
• Wine is filtered to remove yeast, stopping fermentation
• Residual sugar remains, creating a sweeter style
• Everything happens in one tank (like a one pot wonder)
• No autolysis or lees aging
• Preserves pure Muscat fruit character

Asti vs. Moscato d'Asti

• Asti: More full sparkling, higher atmospheric pressure, slightly higher ABV
• Moscato d'Asti: Lower atmospheric pressure, slightly lower alcohol
• Moscato d'Asti uses superior grapes, so overall quality is better
