Narrative

Type = wine grape. Per Brooks and Olmo (see citation): "Fruit: cluster large, 600-700 gm, conical, well-filled, very symmetrical; berry round; skin dark bluish-green, thick, lenticels few; pulp bright green, soft, gelatinous, not very juicy, high in acidity, for production of white table wine of good acidity, of Chablis type. Vine: vigorous; spreading; heavy foliage; wood matures late in autumn; very productive." Information taken from www.wineloverspage.com/wineguest/wgg.html: "Probably the most successful of the attempts to breed high quality/quantity white-wine grapes for specific use in California."
