How is must stored for production using the Asti method?
At 0˚C until needed
For Asti production, what is the first step after the must is taken from cold storage?
The must is clarified, yeast is added as it is transferred to pressure tanks
For Asti production, CO2 is produced along side primary ferment. What are the 2 variations used to achieve this?
must is warmed to 16-18°C and fermented to about 6% abv before the tank is sealed and pressure is allowed to build up so that the CO2 from the last 1.5% abv OR some CO2 is retained from the very start of the ferment
