Sparkling — Charmat (tank method)
Tank-method sparkling. Faster + cheaper than traditional method. Produces fresh fruit-driven sparkling wine for drink-young consumption. Prosecco is the dominant example.
About Charmat
Charmat method sparkling wine (also called Martinotti method, named after the Italian inventor) is editorially the second sparkling-wine category — producing fresh, fruit-driven sparkling wine for drink-young consumption rather than the brioche-and-biscuit complexity of traditional-method sparkling. The key difference is where secondary fermentation occurs: Charmat method conducts secondary fermentation in a large sealed pressurized stainless steel tank rather than inside individual bottles. The wine is then filtered and bottled under pressure to retain the CO2. The total production process is dramatically faster (months vs years), cheaper, and produces a different flavor profile: minimal yeast-lees autolysis means no brioche complexity; instead the focus is on preserving fresh fruit aromatics from the base grapes. Prosecco DOC and DOCG (using the Glera grape from northeastern Italy’s Veneto region) is the dominant commercial example, accounting for the majority of global sparkling wine consumption by volume. Asti DOCG (sweet, low-alcohol, Moscato-based) is another canonical Charmat example. Charmat method is editorially appropriate for its category — it’s not “inferior” to traditional method, it’s a different wine designed for different consumption occasions.

Editorial notes
Charmat sparkling is editorially appropriate for drink-young, fruit-driven consumption — not a quality compromise compared to traditional method, but a different wine for different occasions. Most Prosecco should be consumed within 1-3 years of vintage release.
