Spelt (Triticum spelta), also known as dinkel wheat[2] or hulled wheat,[2] is a species of wheat. It is a relict crop, eaten in Central Europe and northern Spain. It is considered a health food since it is high in protein. It is comparable to farro.[3]
Spelt was an important staple food in parts of Europe from the Bronze Age to the Middle Ages.
Spelt is sometimes considered a subspecies of the closely related species common wheat (T. aestivum), in which case its botanical name is considered to be Triticum aestivum subsp. spelta.
Evolution
[edit]Like common wheat, spelt is a hexaploid wheat species, which means it has six sets of chromosomes. It is derived from hybridization between a domesticated tetraploid wheat such as emmer wheat and another wheat species. Spelt may have had either two separate origins in Asia and Europe, or a single origin.[4]
Genetic evidence indicates spelt originated as a naturally occurring hybrid of a domesticated tetraploid wheat and the diploid wild goat-grass Aegilops tauschii. Genetic evidence shows that spelt wheat can also arise as the result of the hybridisation of bread wheat and emmer wheat, although only at some date following the initial Aegilops–tetraploid wheat hybridisation. The much later appearance of spelt in Europe might thus be the result of a later, second, hybridisation between emmer and bread wheat. DNA evidence supports an independent origin for European spelt through this hybridisation.[4][5]
Pm5 is an effector-triggered resistance (ETR) gene for powdery mildew.[6] Pm5 was found by Keller et al., 1999 and they originally misidentified it as a quantitative trait locus (QTL) due to polymorphism in the pathogen for virulence/avirulence.[6]
Terminological confusion with other hulled wheats
[edit]Especially in the context of descriptions of ancient cultures, the English word spelt has sometimes been used to refer to grains that were not hexaploid T. spelta, but other species of hulled wheat such as tetraploid T. dicoccum (emmer wheat) or diploid T. monococcum (einkorn wheat, also known as "little spelt" or "littlespelt", in French "petit épeautre"). This confusion may arise either from mistranslation of words found in other languages that can refer to hulled wheat in general without distinguishing between these species (such as Italian farro) or changing opinions about which actual species of wheat are described in texts written in ancient languages.
The meaning of the Ancient Greek word ζειά ([zeiá]) or ζέα is either uncertain or vague and has been argued to refer to T. dicoccum or T. monococcum[7] rather than T. spelta.[8] Likewise, the Ancient Roman grain denoted by the Latin word far, although often translated as "spelt", was in fact emmer (T. dicoccum).[9]
Similarly, references to the cultivation of spelt wheat in Biblical times (see matzo), in ancient Egypt and Mesopotamia are incorrect and result from confusion with emmer wheat.[10]
History
[edit]Spelt has been cultivated since approximately 5000 BCE. The earliest archaeological evidence of spelt is from the fifth millennium BCE in Transcaucasia, north-east of the Black Sea, though the most abundant and best-documented archaeological evidence of spelt is in Europe.[11] Remains of spelt have been found in some later Neolithic sites (2500–1700 BCE) in Central Europe.[11][12] During the Bronze Age, spelt spread widely in central Europe. In the Iron Age (750–15 BCE), spelt became a principal wheat species in southern Germany and Switzerland, and by 500 BCE, it was in common use in southern Britain.[11] There is evidence that spelt cultivation increased in Iron Age Britain as damp regions of the country with heavy soils tolerated by spelt were being settled.[13]
In the Middle Ages, spelt was cultivated in parts of Switzerland, Tyrol, Germany, northern France and the southern Low Countries.[14] Spelt became a major crop in Europe in the 9th century CE, possibly because it is husked, unlike other grains, and therefore more adaptable to cold climates and is more suitable for storage.[15]
Spelt was introduced to the United States in the 1890s. In the 20th century, spelt was replaced by bread wheat in almost all areas where it was still grown. The organic farming movement revived its popularity somewhat toward the end of the century, as spelt requires less fertilizer.[16] Since the beginning of the 21st century, spelt has become a common wheat substitute for making artisanal loaves of bread, pasta, and flakes.[17] By 2014, the grain was popular in the UK with the crop being grown there as well as in Kazakhstan and Ukraine, with shortages reported.[18]

A 100-gram (3+1⁄2-ounce) reference serving of uncooked spelt provides 1,400 kilojoules (340 kilocalories) of food energy and is a rich source (20% or more of the Daily Value) of protein, dietary fiber, several B vitamins, and numerous dietary minerals (table). Highest nutrient contents include manganese (143% DV), phosphorus (57% DV), and niacin (46% DV). Spelt contains about 70% total carbohydrates, including 11% as dietary fibre, and is low in fat (table).
Spelt contains gluten, and is therefore suitable for baking, but this component makes it unsuitable for people with gluten-related disorders,[21] such as celiac disease,[22] non-celiac gluten sensitivity, and wheat allergy.[21] In comparison to hard red winter wheat, spelt has a more soluble protein matrix characterized by a higher gliadin:glutenin ratio.[23][24]
Products
[edit]In Germany and Austria, spelt loaves and rolls (dinkelbrot) are widely available in bakeries, as is spelt flour in supermarkets. The unripe spelt grains are dried and eaten as grünkern ("green grain").
Dutch jenever makers distill with spelt.[25] Beer brewed from spelt is sometimes seen in Bavaria[26] and Belgium.[27]
