Limpa bread (Swedish: vörtbröd) is a sweet Scandinavian rye bread, associated with Swedish cuisine. It is a yeast-leavened, butter-enriched spice loaf, sweetened with brown sugar and molasses. Its distinct taste and look is in a large part due to the addition of wort to the dough, making it similar to a malt loaf. Typically baked during the Christmas season, the festive loaves are flavored with spices like anise, caraway or fennel seeds, and often orange rinds, raisins or sultanas, and dark beer, in addition to the wort. It is a typical dish for a traditional Christmas Eve smörgåsbord or julbord. Limpa bread pairs well with jams and jellies, or cream cheese. In Sweden this kind of bread is known as vörtbröd or vörtlimpa, whereas limpa refers to a loaf of bread of any kind.
The first step for making the bread is to bring molasses, brown sugar, caraway seeds, wort and water to a gentle boil, then to add shortening or butter and citrus rind. Once this mixture has cooled to a lukewarm temperature it is combined with activated yeast and rye flour. The dough rises and more flour is added to knead the dough in preparation for a second rise, then the tops are brushed with melted butter and the loaves are baked. Some recipes add the molasses mixture to the dry ingredients after the rye flour has been scalded with hot water.
Historically, this bread was leavened with fermented brewer's wort, hence its Swedish name vörtlimpa or vörtbröd ("wort loaf" or "wort bread"). Modern recipes do sometimes still use stout beer as an ingredient.
The recipes vary, some replacing caraway with cardamom, or leaving out the orange peel; in the United States its most common form is an aromatic orange and spice loaf.
Molasses adds color to the brown bread, made with a blend of rye and other flours. Other flours blended in with the rye, depending on the recipe, can include cornmeal, whole wheat flour or all purpose flour. To add the orange flavor orange oil or orange zest can be used.  Although not strictly traditional in the origin area of northern Sweden, some variations on the basic recipe may add raisins or prunes. This is however traditional in southern Sweden where wort bread was adopted later.
