The Asti Method
What is the major difference in style between Moscato d’Asti DOCG & Asti DOCG?
Asti DOCG is typically higher in alcohol and fully sparkling
MdA DOCG is yupically lower in alcohol, semi-sparkling, and typically has higher residual sugar.
What is the climate in Asti DOCG?
Moderate Continental
Growing regulations for sparkling Asti wines dictate that grapes must be grown on _____________?
Hillsides
Max yields for Asti sparkling wine?
75 hL/ha
What is the typical vine training system used for Asti sparkling wines?
Guyot with vertical shoot positioning
Is mechanical harvesting approved for sparkling Asti production?
Yes, and it is used increasingly so in cheaper, more affordable wines.
Asti Winemaking Phase 1:
Grapes are pressed whole cluster or de-stemmed, and pressed as fast as possible to minimize oxidation. The must is then clarified. Wines are split into to phases: Phase 1: production, clarification, and filtration of the must, followed by chilling and storage. Must can be stored for up to two years. Phase 2: single fermentation of the warmed-up must when required on demand. Fermentation takes place in pressure-resistant temperature-controlled tanks at low temps (61-64F) to preserve primary fruit. MLF is prevented to conserve already lacking acidity.
Asti Winemaking Phase 2:
Phase 2: single fermentation of the warmed-up must when required on demand. Fermentation takes place in pressure-resistant temperature-controlled tanks at low temps (61-64F) to preserve primary fruit. MLF is prevented to conserve already lacking acidity. Asti wines are made into sparkling wine through a single fermentation in pressurized tanks. Sugar, which is converted into CO2 comes from the sugar in the original must, not tirage. Residual sugar comes from stopping the fermentation before dryness, not dosage.
Asti Winemaking Continued:
At the start of fermentation, Co2 produced was a party of the fermentation process is released through a valve in the tank. The fermenting must will be monitored regularly to check on the falling sugar levels. The amount of sugar required to give the desired pressure (Frizzante or Spumante) and leave the desired final level of residual sugar in the wine is calculated and, once this level is reached, the valve in the tank is closed and the co2 from the fermentation is retained. Once the desired residual sugar levels and pressure is obtained, the fermentation is stopped by rapidly chilling the wine and filtering it under pressure to remove the yeast. Wines is released a few weeks after production, and is intended to be consumed young.
Asti DOCG
Final alcohol = 6-8% ABV. Residual sugar levels are typically around 100g/l. Drier styles have recently been permitted and even Brute Nature is being tested for approval.
Asti Metodo Classico?
New style: Minimum 9 months on less (in bottle). Must be Dolce in sweetness (above 50 g/l RS)
