What is Merino?

The Merino is one of the most historically relevant and economically influential breeds of sheep, much prized for its wool. The breed was originated and improved in Extremadura, in southwestern Spain, around the 12th century; it was instrumental in the economic development of 15th and 16th century Spain, which held a monopoly on its trade, and since the end of the 18th century it was further refined in New Zealand and Australia, giving rise to the modern Merino.
Today, Merinos are still regarded as having some of the finest and softest wool of any sheep. Poll Merinos have no horns (or very small stubs, known as scurs), and horned Merino rams have long, spiral horns which grow close to the head.
Merino wool is fine and soft. Staples are commonly 65–100 mm (2.6–3.9 in) long. A Saxon Merino produces 3–6 kg (6.6–13.2 lb) of greasy wool a year, while a good quality Peppin Merino ram produces up to 18 kg (40 lb). Merino wool is generally less than 24 micron (µm) in diameter. Basic Merino types include: strong (broad) wool (23–24.5 µm), medium wool (19.6–22.9 µm), fine (18.6–19.5 µm), superfine (15–18.5 µm) and ultra fine (11.5–15 µm). Ultra fine wool is suitable for blending with other fibers such as silk and cashmere.
The term merino is widely used in the textile industries, but it cannot be taken to mean the fabric in question is actually 100% merino wool from a Merino strain bred specifically for its wool. The wool of any Merino sheep, whether reared in Spain or elsewhere, is known as "merino wool". However, not all merino sheep produce wool suitable for clothing, and especially for clothing worn next to the skin. This depends on the particular strain of the breed. Merino sheep bred for meat do not produce a fleece with a fine enough staple for this purpose.
The Napoleonic wars (1793–1813) almost destroyed the Spanish Merino industry. The old cabañas were dispersed or slaughtered. From 1810 onwards, the Merino scene shifted to Germany, the United States and Australia. Saxony lifted the export ban on living Merinos after the Napoleonic wars. Highly decorated Saxon sheep breeder Nake from Rennersdorf had established a private sheep farm in Kleindrebnitz in 1811, but ironically after the success of his sheep export to Australia and Russia, failed with his own undertaking.
Sir Joseph Banks procured two rams and four ewes in 1787 by way of Portugal, and in 1792 purchased 40 Negrettis for King George III to found the royal flock at Kew. In 1808, 2000 Paulas were imported.
The three Merino strains that founded the world's Merino flocks are the Royal Escurial flocks, the Negretti and the Paula. Among Merino bloodlines stemming from Vermont in the USA, three historical studs were highly important: Infantado, Montarcos and Aguires.
The Phoenicians introduced sheep from Asia Minor into North Africa and the foundation flocks of the merino in Spain might have been introduced as late as the 12th century by the Marinids, a tribe of Berbers. although there were reports of the breed in the Iberian peninsula before the arrival of the Marinids; perhaps these came from the Merinos or tax collectors of the Kingdom of León, who charged the tenth in wool, beef jerky and cheese. In the 13th and 14th centuries, Spanish breeders introduced English breeds which they bred with local breeds to develop the merino; this influence was openly documented by Spanish writers at the time.
Spain became noted for its fine wool (spinning count between 60s and 64s) and built up a fine wool monopoly between the 12th and 16th centuries, with wool commerce to Flanders and England being a source of income for Castile in the Late Middle Ages.
Most of the flocks were owned by nobility or the church; the sheep grazed the Spanish southern plains in winter and the northern highlands in summer. The Mesta was an organisation of privileged sheep owners who developed the breed and controlled the migrations along cañadas reales suitable for grazing.
Before the 18th century, the export of Merinos from Spain was a crime punishable by death. In the 18th century, small exportation of Merinos from Spain and local sheep were used as the foundation of Merino flocks in other countries. In 1723, some were exported to Sweden, but the first major consignment of Escurials was sent by Charles III of Spain to his cousin, Prince Xavier the Elector of Saxony, in 1765. Further exportation of Escurials to Saxony occurred in 1774, to Hungary in 1775 and to Prussia in 1786. Later in 1786, Louis XVI of France received 366 sheep selected from 10 different cañadas; these founded the stud at the Royal Farm at Rambouillet. The Rambouillet stud enjoyed some undisclosed genetic development with some English long-wool genes contributing to the size and wool-type of the French sheep. Through one ram in particular named Emperor – imported to Australia in 1860 by the Peppin brothers of Wanganella, New South Wales – the Rambouillet stud had an enormous influence on the development of the Australian Merino.
The King of Spain also gave some Escurials to the Dutch government in 1790; these thrived in the Dutch Cape Colony (South Africa). In 1788, John MacArthur, from the Clan Arthur (or MacArthur Clan) introduced Merinos to Australia from South Africa.
From 1765, the Germans in Saxony crossed the Spanish Merino with the Saxon sheep to develop a dense, fine type of Merino (spinning count between 70s and 80s) adapted to its new environment. From 1778, the Saxon breeding center was operated in the Vorwerk Rennersdorf. It was administered from 1796 by Johann Gottfried Nake, who developed scientific crossing methods to further improve the Saxon Merino. By 1802, the region had four million Saxon Merino sheep, and was becoming the centre for stud Merino breeding, and German wool was considered to be the finest in the world.
In 1802, Colonel David Humphreys, United States Ambassador to Spain, introduced the Vermont strain into North America with an importation of 21 rams and 70 ewes from Portugal and a further importation of 100 Infantado Merinos in 1808. The British embargo on wool and wool clothing exports to the U.S. before the 1812 British/U.S. war led to a "Merino Craze", with William Jarvis of the Diplomatic Corps importing at least 3,500 sheep between 1809 and 1811 through Portugal.
