Sweet red wine is a broad category encompassing red wines that retain a significant amount of residual sugar after fermentation, resulting in a noticeable sweetness on the palate. Unlike dry red wines, where most of the grape's sugar is converted into alcohol, sweet reds are intentionally produced to have a sweeter profile.  

Here's a breakdown of common characteristics and styles: 

Key Characteristics:

• Sweetness: This is the defining characteristic. The level of sweetness can range from slightly off-dry to intensely sweet, depending on the specific wine and production methods.  
• Fruity Flavors: Sweet red wines often showcase prominent fruit flavors, typically leaning towards ripe red berries (strawberry, raspberry, cherry), dark berries (blackberry, plum), and sometimes even jammy or candied fruit notes.  
• Lower Tannins: Compared to dry red wines, sweet reds generally have lower tannin levels. Tannins contribute to a dry, sometimes astringent feel, which is less prominent in sweeter styles. This makes them smoother and easier to drink.
• Often Lighter Body: While some sweet red wines can have a medium body, many tend to be lighter-bodied, contributing to their approachability.
• Lower Alcohol Content: Similar to sweet white wines like Moscato, some sweet red wines have a lower alcohol content, making them more sessionable.
• Can be Still or Sparkling: Sweet red wines can be either still (non-sparkling) or sparkling. Sparkling sweet red wines, like Lambrusco Dolce or Brachetto d'Acqui, offer a refreshing effervescence alongside the sweetness and fruit.
