From ChatGPT: Flavored Fortified Wines are a type of inexpensive wine that is fortified with additional alcohol and flavored with various additives such as artificial sweeteners, fruit flavorings, and colorings. They are typically made from low-quality grape wines that are then fortified with distilled spirits such as brandy, and sweetened with sugar or other sweeteners to create a sweeter, more palatable taste.

These types of wines are often referred to as "bum wines" or "forties," due to their popularity among lower-income and college-aged drinkers. Some popular brands of cheap American Flavored Fortified Wines include MD 20/20, Night Train, Thunderbird, and Wild Irish Rose.

One reason for their popularity is their relatively low price point, with bottles typically costing between two and five dollars. They are also often sold in large 40-ounce bottles, making them a popular choice for parties and gatherings.

However, these wines are often associated with negative social connotations, and are frequently consumed by people who are struggling with addiction or other issues. They have a higher alcohol content than most table wines, with some brands containing up to 18% alcohol by volume, which can lead to a greater risk of intoxication and related health issues.

Overall, while cheap American Flavored Fortified Wines can offer a sweet and potent taste experience at a low price point, they are not generally considered to be high-quality wines, and their use is often associated with negative stereotypes and health risks.
