Note: The Canelli subzone has reportedly been approved for separate DOCG status as of April 2023. This entry will be updated when official confirmation is received.
Note: Prior to 2017, all fully sparkling Asti was required to be dolce, and the maximum alcohol level was 9.5%. From then until 2020, sweetness levels between extra dry and dolce were allowed, with a maximum alcohol level of 8.0%. Changes in 2020 opened the doors for all sweetness levels and removed the maximum alcohol level limit.
