Why are fortified wines typically served in small glasses?

Fortified wines are typically served in small glasses primarily because they have a high alcohol content. These wines, which include varieties like Port, Sherry, and Madeira, are produced by adding distilled spirits to the wine, which increases the overall alcohol level. This elevated strength means that a smaller portion is sufficient to enjoy the complex flavors and aromas without overwhelming the palate or leading to overconsumption.

Serving fortified wines in smaller glasses not only acknowledges their higher alcohol content but also encourages a more deliberate tasting experience, allowing drinkers to savor the nuanced flavors that fortified wines have to offer. This practice contrasts with standard wines, which are generally lower in alcohol and can be enjoyed in larger servings.

While other choices may touch on aspects related to consumption and flavor, they do not accurately represent the primary rationale for serving fortified wines in small glasses. The focus on alcohol content directly addresses the need for moderation in serving size, making it the most relevant answer.
