Semi-Sparkling Wine
Wine with low CO₂ pressure (1–2.5 bar); frizzante style.
Semi-sparkling wine occupies the middle ground between still and fully sparkling styles, carrying a gentle, persistent prickle rather than the assertive mousse of Champagne or spumante. Under EU rules, the category is defined precisely as wine with between 1 and 2.5 atmospheres of CO2 pressure in the bottle, measured at 20 degrees Celsius. The same style travels under several regional names you will see on labels: frizzante in Italy, petillant in France, and Perlwein or spritzig in Germany.
How the Pressure Defines the Category
The boundary is regulatory, not just stylistic. EU law sets semi-sparkling wine at 1 to 2.5 atmospheres, while wines above 3 atmospheres fall into the fully sparkling category. For context, Champagne and other traditional sparkling wines are typically bottled at 5 to 6 atmospheres, roughly 73 to 88 psi, so a frizzante carries something like a quarter to half of that pressure.
The pressure itself is a function of secondary fermentation. The more sugar the winemaker adds for that second ferment, the more CO2 the yeast produces, and the higher the final pressure in the bottle. Dialing that dosage down is what keeps a wine in the semi-sparkling band rather than pushing it into spumante territory.
Germany draws the line especially clearly in its wine law. Perlwein is the semi-sparkling category, kept separate from Sekt, which is fully sparkling and made by traditional or Charmat methods, and from Schaumwein, a lower-grade sparkling wine often produced by direct CO2 injection.
Classic Styles to Know
Italy is the spiritual home of the category, and frizzante shows up in several iconic wines. Lambrusco from Emilia is the red benchmark, lively and food-friendly. Moscato d'Asti is the sweet, aromatic counterpoint, and the Valdobbiadene area produces frizzante-style Prosecco alongside its better-known spumante version.
Moscato d'Asti is a useful example of what the format makes possible. It is a frizzante version of Asti, bottled with notable residual sugar and an unusually low alcohol level of around 5.5 percent ABV, the kind of wine that pairs naturally with fruit and pastry rather than a full meal.
Prosecco illustrates how the same appellation can straddle both styles. Under the same DOC and DOCG framework, producers can release a spumante for fully sparkling expressions and a frizzante for the gentler, lower-pressure version, giving drinkers a clear stylistic choice within one denomination.
