No, although these terms are often used interchangeably, they are two different drinks. They have similar ingredients but can hold their own in the flavor category. Wassail is cider based and includes sugar, spices, sometimes cranberries, and is filled with other tangy juice such as lemonade or orange juice. Mulled wine does typically contain wine, spices, and whole oranges that sit in the drink and add their own flavor. These two drinks are similar and have long since been popular choices around the holidays, but it’s helpful to understand the small differences they have.
