Understanding the Brewing Process and Residual Sugars
To understand why a can of VB has no sugar, it is helpful to look at how beer is made. The main ingredients in most beer are water, a grain such as barley, yeast, and hops. During the brewing process, the malted grains are heated in water, releasing complex carbohydrates and sugars into a sweet liquid called 'wort'.
Next, the yeast is added to the wort in a process known as fermentation. The yeast's primary function is to consume the fermentable sugars, converting them into alcohol and carbon dioxide. For many standard lagers and ales, this fermentation is very efficient, leaving behind a small amount of residual sugars and unfermentable carbohydrates that contribute to the beer's body and flavor. In the case of a standard VB, fermentation is so complete that the final product contains no measurable sugar.
VB vs. VB Low Carb
With the introduction of VB Low Carb, it's important to differentiate between the nutritional profiles of the two. While both are very low in sugar, there are distinct differences in their overall carbohydrate counts. The standard VB has a slightly higher carbohydrate content due to the presence of unfermentable carbohydrates that add to its body and mouthfeel. The low-carb version is brewed specifically to minimize these non-sugar carbohydrates as well, resulting in a product with fewer overall carbs.
The Role of Adjuncts
As noted on its Wikipedia page, VB has historically used cane sugar as an adjunct to 'thin out the body of the beer'. This does not mean the final product contains sugar. The cane sugar added during the brewing phase is a fermentable sugar, which the yeast will fully consume during fermentation, just like the maltose from the grain. This use of an adjunct sugar is different from adding sweeteners after fermentation, which would result in a sweeter, higher-sugar beer.
Comparison of Sugar and Carbohydrate Content
For those comparing VB with other beverages, here's a look at the sugar and carbohydrate content in a 375ml serving. Note that standard sodas and other sugary drinks have significantly higher sugar counts.
| Beverage | Serving Size | Total Sugar | Total Carbohydrates |
|---|---|---|---|
| VB (Victoria Bitter) | 375ml | 0g | 11.6g |
| VB Low Carb | 375ml | 1g (approx) | 7g |
| Regular Cola | 375ml | ~40g | ~40g |
| Orange Juice | 375ml | ~35g | ~35g |
| Standard Lager (UK) | 375ml (approx) | <1g | ~7g |
This table illustrates the stark difference between a beer like VB and other common beverages. The key distinction is the source of calories and carbohydrates—in VB, it's mostly alcohol and unfermentable carbohydrates, while in soft drinks, it is primarily sugar.
Why are low-alcohol beers sometimes higher in sugar?
It is an interesting paradox that some low-alcohol or alcohol-free beers can contain more sugar than a standard brew like VB. This is because the fermentation process is either stopped early or deliberately manipulated to produce less alcohol. When fermentation is halted, not all the fermentable sugars are converted to alcohol, leaving a higher residual sugar content in the final beer. For this reason, those watching their sugar intake should always check the nutritional information on low-alcohol or non-alcoholic beers, as they may be surprisingly high in sugar.
The Health Context of Drinking VB
While VB contains no sugar, it is not a calorie-free drink. The calories in beer come mainly from the alcohol and the leftover carbohydrates. For example, a 375ml can of VB contains around 151 calories (634 kJ). It is important to remember that excessive alcohol consumption has negative health consequences and the calorie content, even without sugar, can contribute to weight gain if not consumed in moderation. As with any alcoholic beverage, balance and moderation are key to a healthy lifestyle.
Conclusion: VB is a Zero-Sugar Beer
In summary, a standard can of VB beer contains 0 grams of sugar. The brewing process uses yeast to consume all the fermentable sugars, converting them into alcohol and carbon dioxide. While it is sugar-free, it still contains calories from alcohol and carbohydrates. For those seeking even fewer carbs, the recently launched VB Low Carb version is a suitable alternative. When choosing a beer based on its sugar content, it's the fermentation process that determines the final amount, making a standard lager like VB naturally low in sugar.
