Freeze! You’re Under Arrest
The Asti method of making Moscato d’Asti sparkling wine is unusual because it only undergoes one alcoholic fermentation: the juice is chilled until needed, arresting the fermentation. When the winemaker wants to produce wine, they warm up the juice and allow fermentation to happen
until the alcohol hits about 7% ABV. From then, fermentation is stopped by re-chilling the wine.
