Other than the Apple from Cupertino, my favourite apple has to be a Pink Lady. Thankfully, the quest for my preferred apple is made easier by some brilliant branding.
The Pink Lady apple is really a variety of apple called a Cripps Pink, which is a hybrid of a Lady Williams apple and a Golden Delicious apple. According to Wikipedia the Pink Lady is "owned and licensed by the Department of Agriculture and Food, Western Australia (DAFWA), which has Plant Breeders' Rights in multiple countries".
Cultivated by thousands of producers, Pink Lady apples have to meet stringent specifications, before they can carry the Pink Lady brand. Therefore, whenever you go to buy an apple, keep an eye out for the Pink Lady sticker and you can be assured of a delicious apple, that is both tart and crisp.
Although the execution of the logotype is really nice, the real brilliance is in the consistency of the product and branding across the world. It's the Coca-Cola of apples.
Also, if you're a fan of Pink Lady apples, the Jazz Apple is also another excellent apple, of a much more recent splicing.
