What character does a beer typically exhibit when it has high residual sugars?

When a beer has high residual sugars, it typically exhibits a character of richness. This is because residual sugars contribute to the beer’s overall mouthfeel and sweetness, resulting in a fuller, more robust flavor profile. The presence of these sugars balances bitterness from hops and other flavor aspects, creating a more complex beer experience. A rich character often enhances the perception of body and can elevate flavors such as caramel, toffee, and other malt-driven notes.

The other options do not accurately represent the impact of high residual sugars in beer. Dryness usually correlates with a lack of sugars and a more attenuated fermentation, whereas sourness is associated with specific yeast or bacteria that produce acids, rather than sugars. Lightness typically refers to a lower body and less intense flavor, which would be contrary to the sensations provided by high residual sugars. Therefore, richness is the key character associated with beers that have high residual sugar content.
