Sparkling wines produced using the Charmat Process are characterized by larger bubbles that tend to be less persistent compared to those found in traditionally made sparkling wines, such as those produced using the méthode champenoise. This method involves secondary fermentation occurring in large pressurized tanks, which introduces carbon dioxide into the wine.

As a result, the carbonation is often introduced more rapidly, leading to larger bubbles. While these bubbles can create a lively and refreshing drinking experience, they are typically less enduring than the finer, smaller bubbles produced through the traditional method, where fermentation occurs in individual bottles and encourages a more gradual integration of gas. Therefore, the nature of the bubbles in Charmat-produced sparkling wines aligns with the observation of their larger size and shorter duration in comparison to other sparkling wine production techniques.

The other options mention characteristics such as higher acidity, fuller body, and a long-lasting bubble experience, which do not specifically define the Charmat Process, further cementing the understanding that larger bubbles with less persistence most accurately describe this method.
