Bual is a type of dessert wine produced primarily in the Madeira region of Portugal. It is made from the Bual grape variety, known for its rich, sweet flavor profile. This wine typically has notes of caramel, nuts, and dried fruits, making it a popular choice for pairing with desserts or enjoying on its own. The production of Bual involves a unique process called estufagem, where the wine is heated to enhance its flavors and stability. Bual wines can range from medium to full-bodied and are often aged for several years, resulting in a complex taste that appeals to many wine enthusiasts.
