OCW 3rd:
"Eger
much-disputed town in north east hungary whose wines have been exported with success since the 13th century, although various Turkish incursions interrupted this trade. Eger's most famous siege was during the Ottoman occupation of the 16th century when, according to legend, the defenders of Eger were so dramatically fortified by a red liquid which stained their beards and armour that the Turks retreated, believing their opponents to have drunk Bikavér, or bull's blood.
"The town gives its name to a wine region on the foothills of the volcanic Bükk mountains where rainfall is low and spring tends to come late. As well as producing Egri Bikavér, currently being revived and rehabilitated, the region produces white wines, notably from leányka grapes."
