Farro is a food product consisting of the grains of certain wheat species in whole form. The exact definition is debated. It is sold dried and is prepared by cooking in water until soft, but still crunchy . It may be eaten plain, though it is often used as an ingredient in dishes such as salads and...

. On threshing, a hulled wheat spike breaks up into spikelets. These require milling or pounding to release the grains from the glumes.

Wild emmer wheat spikelets effectively self-cultivate by propelling themselves mechanically into soils with their awns. During a period of increased humidity during the night, the awns of the spikelet become erect and draw together, and in the process push the grain into the soil. During the daytime the humidity drops and the awns slacken back again; however, fine silica hairs on the awns act as hooks in the soil and prevent the spikelets from reversing back out again. During the course of alternating stages of daytime and nighttime humidity, the awns' pumping movements, which resemble a swimming frog kick

Cultivation

Today emmer is primarily a relict crop in mountainous areas. Its value lies in its ability to give good yields on poor soils, and its resistance to fungal diseases such as stem rust

 that are prevalent in wet areas. Emmer is grown in Armenia, Morocco, Spain (Asturias), the Carpathian mountains on the border of the Czech and Slovak republics, Albania, Turkey, Switzerland and Italy. It is also grown in the U.S. as a specialty product. A traditional food plant in Ethiopia, this relatively little-known grain has potential to improve nutrition, boost food security, foster rural development and support sustainable landcare.

In Italy, uniquely, emmer cultivation is well established and even expanding. In the mountainous Garfagnana area of Tuscany emmer (known as farro) is grown by farmers as an IGP (Indicazione Geografica Protetta

) product, with its geographic identity protected by law. Production is certified by a co-operative body, the Consorzio Produttori Farro della Garfagnana. IGP-certified farro is widely available in health food shops across Europe, and even in some British supermarkets. The demand for Italian farro has led to competition from non-certified farro, grown in lowland areas and often consisting of a different wheat species, spelt (Triticum spelta).

Food uses

Emmer's main use is as a human food, though it is also used for animal feed. Ethnographic evidence from Turkey and other emmer-growing areas suggests that emmer makes good bread (judged by the taste and texture standards of traditional bread), and this is supported by evidence of its widespread consumption as bread in ancient Egypt. Emmer bread is available in Switzerland. In Italy, whole emmer grains can be easily found in most supermarkets and groceries, emmer bread (pane di farro) can be found in bakeries in some areas, and emmer has traditionally been consumed in Tuscany as whole grain in soup.
