The white grape variety (also Geilweilerhof 33-13-113) is a new variety between(Silvaner x Riesling) x Müller-Thurgau according to DNA analyses published in 2012. The cross was made in 1930 by the breeder Peter Morio (1887-1960) at the Institute for Grapevine Breeding Geilweilerhof in Siebeldingen-Pfalz. The plant variety protection was granted in 1971. By the way, the variety Bacchus was created with the same parents. Optima was a cross-breeding partner for the new varieties Geilweilerhof GA58-14 and Orion. The very early ripening vine is resistant to downy mildew, but sensitive to frost and susceptible to botrytis. It produces yellow-green, low-acid wines with a Riesling like aroma. The variety occupies 24 hectares in Germany, and the tendency is strongly decreasing. Small stands can also be found in Austria, England and Canada (6 ha). In 2016, a total of 30 hectares of vineyard area were designated (statistics Kym Anderson)
