The 51st Battalion (Edmonton), CEF, was an infantry battalion of the Canadian Expeditionary Force during the Great War. The 51st Battalion was authorized on 7 November 1914 and embarked for Great Britain on 18 April 1916. It provided reinforcements for the Canadian Corps in the field until 13 November 1916, when it was reorganized as a garrison duty battalion. On 22 June 1917, its personnel were absorbed by the various regimental depots. The battalion was disbanded on 15 September 1920.

Spanish wine includes red, white, and sparkling wines produced throughout the country. Located on the Iberian Peninsula, Spain has over 1.2 million hectares planted in wine grapes, making it the most widely planted wine-producing nation, but the third largest producer of wine in the world, behind Italy and France and ahead of the United States; this is due, in part, to the very low yields and wide spacing of the old vines planted on the dry soils found in some of the Spanish wine regions. The country is second in wine exports and ninth in worldwide consumption, with Spaniards drinking, on average, 21.6 litres (5.7 US gal) per person a year. The country has an abundance of native grape varieties, with over 400 varieties planted throughout Spain, though 88 percent of the country's wine production is from only 20 grapes — including the reds Tempranillo, Bobal, Garnacha, and Monastrell; the whites Albariño, Airén, Verdejo, Palomino, and Macabeo; and the three Cava grapes Parellada, Xarel·lo, and Macabeo.
