Understanding Residual Sugar (RS) in Prosecco
The perception of Prosecco's sweetness is not as straightforward as it seems. While the Glera grape naturally has fruity notes of pear, apple, and melon, these aromas can sometimes be mistaken for sugar. The actual sugar content, known as residual sugar (RS), is measured in grams per liter (g/L) and is determined by a process called dosage.
The Charmat Method and Dosage
Unlike Champagne, which undergoes a secondary fermentation in the bottle, Prosecco is primarily produced using the Charmat (or Martinotti) method. This involves a second fermentation in large pressurized steel tanks, which is a quicker and more cost-effective process. After the fermentation is complete, a mixture of wine and sugar, the dosage, is added to the wine before bottling. It is the quantity of this final sugar addition that dictates the Prosecco's sweetness level and, therefore, its classification on the label.
Decoding Prosecco Sweetness Levels
To understand the sugar content, you need to know how to read the label. The official classifications, from driest to sweetest, are as follows:
- Brut Nature (0-3 g/L RS): The absolute driest style, containing very little to no sugar. This is for purists who prefer an unadulterated taste.
- Extra Brut (0-6 g/L RS): Also very dry, but can have a slightly softer edge than Brut Nature.
- Brut (0-12 g/L RS): The most popular and common style, offering a dry and crisp taste. Most people enjoy this as a versatile option.
- Extra Dry (12-17 g/L RS): Despite the misleading name, this Prosecco is sweeter than Brut and has a more noticeable fruity and smooth character.
- Dry (17-32 g/L RS): Contrary to what one might assume, this is a semi-sweet Prosecco, sweeter than Extra Dry. It pairs well with desserts or spicier foods.
- Demi-Sec (32-50 g/L RS): The sweetest style available, although it is less commonly found.
Prosecco Sugar Comparison
To put Prosecco's sugar content into perspective, let's compare it to other popular beverages. A standard 125ml glass of Brut Prosecco typically contains around 1.5 grams of sugar. The following table compares the average sugar content of various drinks per 100ml:
| Drink | Average Sugar Content per 100ml (g) | 
|---|---|
| Prosecco | 1 | 
| Red Wine | 1 | 
| White Wine | 1 | 
| Rose Wine | 6 | 
| Cider | 4 | 
| Gin and Tonic | 7 | 
| Coca-Cola | 9 | 
| Hot Chocolate | 10 | 
As you can see, the drier styles of Prosecco contain significantly less sugar than many other drinks, including some wines. This is why it is often recommended for those monitoring their calorie and sugar intake.
How to Choose a Lower-Sugar Prosecco
If your goal is to minimize your sugar intake, follow these simple guidelines when selecting a bottle of Prosecco:
- Focus on the Label: Look for the terms Brut Nature, Extra Brut, or Brut. These indicate the lowest levels of residual sugar.
- Be Wary of Names: Remember that the terms Extra Dry and Dry are misleading and refer to sweeter styles of Prosecco, not drier ones.
- Check for Brand Information: Some brands specifically market low-sugar or 'skinny' Prosecco options, which are designed to have minimal or no sugar.
- Don't Confuse Fruity with Sweet: Prosecco made from the Glera grape has natural fruity esters that give it a perception of sweetness even when it has very little sugar. Don't be fooled by the apple and pear notes into thinking it's sugary.
Taste vs. Technical Sweetness
The most important takeaway for many Prosecco drinkers is the difference between technical sweetness (the residual sugar) and perceived sweetness. The fruity and floral aromas of Glera grapes mean that even a Brut Prosecco can taste quite pleasant and round, without being technically sweet. This is a distinct advantage over other sparkling wines, where a similar level of dryness might result in a more austere, acidic profile. This is all due to the different production methods and the characteristics of the grapes used.

Conclusion
To answer the question, "Has Prosecco got a lot of sugar in it?" the definitive answer is: it depends on the style. While the common Brut is relatively low in sugar, other classifications like Extra Dry, Dry, and Demi-Sec contain progressively more. By understanding the classifications on the label, you can easily select a bottle that aligns with your preference for dryness and your dietary needs. So, next time you're choosing your favorite fizz, a quick glance at the label will tell you everything you need to know about its sweetness.
