zeta

Zeta (uppercase Ζ, lowercase ζ; , classical or zḗta, zíta) is the sixth letter of the Greek alphabet. In the system of Greek numerals, it has a value of 7. It was derived from the Phoenician letter zayin . Letters that arose from zeta include the Roman Z and Cyrillic З.

Zéta is a Hungarian wine grape, a crossing of Furmint and Bouvier. It was introduced to the Tokaj-Hegyalja wine region of Hungary in 1951 and authorized for production in 1990. Previously known as Oremus, its name was changed to Zéta in 1999. Its main asset is a particular aptitude for high sugar concentrations, early ripening and susceptibility for botrytis.
