Emmer is a unique hybrid species of wheat.

It was one of the first crops humans domesticated in the Near East. Along with einkorn, it helped shape the history of farming. Today, emmer is often called a relict crop. This means it survives mostly in mountainous regions of Europe and Asia. In Italy, it is recognized as one of three grains called farro. Many people value it for its ability to thrive in poor soil. It also resists fungal diseases like stem rust in wet climates.

Understanding emmer requires looking at its complex biological mechanism.

Emmer is a tetraploid wheat. This means it has four sets of chromosomes. It formed through hybridization between two different wild grasses. These were wild red einkorn and a goatgrass called Aegilops speltoides. This genetic makeup makes it different from simple diploid grasses. The plant produces an elongated spike with long, protruding awns. These awns are the sharp, hair-like spikes extending from the seed head.

The wild version of emmer uses a fascinating mechanical process to plant itself. The awns respond to changes in humidity throughout the day and night. At night, humidity increases and causes the awns to become erect. As they draw together, they push the grain into the soil. During the day, the humidity drops and the awns slacken. Fine silica hairs on the awns act as tiny hooks. These hooks prevent the spikelets from backing out of the dirt. This rhythmic movement resembles the kick of a swimming frog.

There are distinct differences between wild and domesticated types. The wild plant is known as Triticum turgidum subsp. dicoccoides. Its seed head shatters easily, scattering seeds onto the ground. This helps the plant spread in the wild. In contrast, domesticated types like T. t. subsp. dicoccum have intact seed heads. This makes the grain much easier for humans to harvest. Emmer is also a hulled wheat. This means it has strong glumes, or husks, enclosing the grains. To eat the grain, humans must use milling or pounding to remove these tough shells.

The history of emmer stretches back tens of thousands of years. Archaeologists found emmer grains at the Ohalo II site in Israel. These grains were radiocarbon dated to 17,000 BC. This shows hunter-gatherers ate emmer long before formal farming began. The earliest sites of domestication include places like Tell Aswad and Jericho. Definitive evidence for full domestication appears between 10,200 and 9,500 years ago. Scholars suggest the Karaca Dağ mountains in Turkey might be its origin. In 1906, Aaron Aaronsohn discovered wild emmer in Rosh Pinna, which excited the botanical world.

Emmer held a significant place in ancient civilizations. In ancient Egypt, it was a primary wheat for Pharaonic times. It was a main ingredient in bread and beer. Some emmer was even found in the subterranean chambers of the Step Pyramid at Saqqara. In the Near East, it was a prominent crop compared to barley or einkorn. However, cultivation in southern Mesopotamia declined around 3000 BC. This decline is linked to increased salinization of irrigated soils. Barley became more common because it is more tolerant of salt. Emmer was also a significant crop in ancient Israel and was used in religious sacrifices.

Today, emmer remains a culturally important food in many regions. In Armenia, it is used to make emmer pilaf with onions and oil. People also enjoy a porridge called kashovi, which is often cooked with lamb. In Italy, emmer is a major part of the farro tradition. In the Garfagnana area of Tuscany, it is an IGP product. This means its geographic identity is protected by law. It is often called "true" farro because of its high quality. While it is a nutritious grain, it contains gluten. Therefore, it is unsuitable for people with gluten-related disorders.
