Origin Story

Developed at the Institute of Experimental Botany in Prague, Czech Republic, Opal was first introduced in 1999. Its creation was the result of a deliberate cross between two celebrated cultivars, blending the best traits of 'Golden Delicious' and 'Topaz'. Today, Opal is grown commercially across Europe and North America, with licensed growers ensuring its consistent quality and availability.

Classification

Opal belongs to the botanical family Rosaceae, within the genus Malus and species Malus domestica. As a named cultivar, it is recognized internationally under the ICNCP standards and is listed in major plant variety databases. Its classification aligns with global authorities such as the USDA National Plant Germplasm System and the Royal Horticultural Society.

Appearance or Form

Opal apples are medium to large in size, distinguished by their luminous golden-yellow skin, which often features a subtle orange blush. The flesh is pale yellow, crisp, and juicy, offering a visually appealing and aromatic experience. Its inviting color and texture make it stand out both on the tree and in the fruit bowl.

Behavior or Usage

Primarily enjoyed as a dessert apple, Opal is favored for fresh eating thanks to its sweet, tangy flavor and crunchy bite. Its natural resistance to browning makes it ideal for salads, snack platters, and food service, where visual appeal is essential. While suitable for some culinary uses due to its firmness, Opal is not commonly used in cider production.
