25
Describe the ancestral method
Partly fermented must is bottled The remaining sugar converts to CO2 and alcohol, creating natural effervescence Lees filtered (optional) NO dosage
26
What is Pet Nat?
Petillant Naturel Uses ancestral method, no set regulations Low alcohol, cloudy, dry or off dry, unconventional flavors (cider-like) No added SO2 Not meant for aging
27
Three names for tank method?
Charmat Cuve Close Martinotti
28
Describe the tank method
Ferment 16-18C to retain aromatics/flavors Sugar and yeast added to the pressurized tanks One-month second fermentation Cooled to 2-4C to stop fermentation Aged on lees (optional) Cold stabilization/filtration/sugar adjustment Chilled to -2C to stabilize and reduce effervescence Bottled with a counter-pressure filler
29
What is counter-pressure filling?
Bottle filled with CO2 under pressure Filled with chilled wine to replace CO2 Prevents loss of CO2/entrance of O2
30
Describe the Asti method
Similar to tank method, but single fermentation Natural sugar only CO2 initially allowed to escape CO2 valve closed when desired pressure/sugar are reached Stopped by rapidly chilling and filtering
31
Describe carbonation
Least expensive (and prestigious) Used for petillant (low pressure) only Retains aroma/flavor of base wine
