There are a couple hundred varieties of orange, and if you extend it to citrus more generally, there are thousands of varieties. Compare that to the varieties of grapes - there are certainly more strains of grapes in total (5k-10k), but if you restrict yourself to only wine grapes, they are of similar complexity, and the entire grape industry is based on Vitis Vinifera and Vitis Labrusca, whereas Citrus has at least 4 original species. And Citrus reacts just as well as Vitis Vinifera to terroir, as well - Citrus grown in volcanic soil vs limestone soil vs california loam has a distinctly different composition and flavor. You're going to have to face it, wine is special because humans have declared it special, not because it's not similar in complexity to dozens of other agricultural, natural, and fermented products :)
