Optima (grape variety)

from Wikipedia, the free encyclopedia

The white wine variety Optima is a new breed between ( Silvaner x Riesling ) x Müller-Thurgau . The information provided by the breeder about the parents of the cross has been confirmed by DNA analysis in the meantime. The name of the variety is derived from Latin (Optima means the best ). The crossing was made by Peter Morio under further processing by Bernard Husfeld the Institute for Grapevine Breeding Geilweilerhof in Siebeldingen / Pfalz in 1930. The variety was awarded in 1970 the plant variety , and in 1971, entry on the list of varieties . It currently occupies (2007 survey) almost 75 hectares of vineyards, the largest share of which is in the Mosel-Saar-Ruwer and Rheinhessen cultivation areas . The forested area has decreased dramatically in recent years. In 1994 there were still 349 hectares of Optima planted. Small stocks can also be found in Austria , Brazil , Canada , Switzerland , Hungary and South Africa .

The yellow-green, elegant wine has a fragrant bouquet similar to Riesling. A late harvest quality is usually achieved even in weak years. Disadvantages are their susceptibility to gray mold rot ( Botrytis cinerea ) and the overall low yield. Optima is a variety of the noble grapevine ( Vitis vinifera ). It has hermaphroditic flowers and is therefore self-fruiting. In viticulture , the economic disadvantage of not having to grow male plants that produce yield is avoided.
