Heavy bread, also known as dense bread, refers to bread with a dense texture and heavy weight. This type of bread is often made with whole wheat flour, rye flour, or a combination of the two, resulting in a more substantial loaf. Other synonyms for heavy bread include hearty bread, substantial bread, and weighty bread. These types of bread are typically more filling and have a greater nutritional value than white bread, making them a popular choice for sandwiches and toast. Dense bread also tends to have a longer shelf life than lighter varieties, making it an excellent choice for people who like to stock up on pantry staples.
