What Flavor Is Fanta?

Fanta was not orange to begin with. Coca-Cola dates it to 1940 in Germany, when the war cut its German business off from Coca-Cola syrup. Max Keith, who ran Coca-Cola GmbH, had his chemist make a drink from what was available: whey left over from cheesemaking and apple pulp from cider pressing.¹ The name is usually traced to the German word Fantasie, imagination. The wartime drink did not outlast the war by long.

Orange Fanta came in 1955. A Naples bottler had pushed Coca-Cola to back an Italian orange drink, and accounts differ on how much of the formula was worked out in Italy and how much in Atlanta.

Which Fanta do you mean?

Orange is the flagship, but the brand is a family. The US site lists orange, strawberry, grape, peach, pineapple, piña colada and berry.² The UK site lists orange, lemon, Fruit Twist, and pineapple and grapefruit. Coca-Cola's Swiss site adds chinotto, passion fruit and an elderflower-lemon Fanta from Romania, and says the list goes on.

Even the orange is not one drink. Compare the labels:

Why it tastes like orange

Orange oil is mostly limonene, often 90% or more. Limonene on its own smells only faintly of peel. The orange you recognize comes from small amounts of aldehydes, mainly octanal and decanal, with citral and linalool.

Juice adds something else: esters such as ethyl butyrate, which read as fresh and juicy. A soda with no juice tastes of peel and candy more than of squeezed fruit. That is the classic orange soda character, and it is what the US version delivers.

It is also sharp. One US study measured Fanta Orange at pH 2.82, more acidic than Sprite at 3.24.⁴ The acid keeps a very sweet orange from tasting flat.

Building an orange soda

Plan the cloud. Orange soda is opaque, so the oil goes in as an emulsion. The US label lists modified food starch, which coats the oil droplets, and glycerol ester of rosin, which weights them so they do not float to the top.

Watch oxidation. Limonene oxidizes to carvone and limonene oxides. They taste stale, with a turpentine or minty edge. The UK and Mexican labels list ascorbic acid as an antioxidant.

Choose the color for the market. In the UK and EU, sunset yellow and allura red (Yellow 6 and Red 40) carry a mandatory warning about children's activity and attention. Carotenoid colors from carrot or paprika are the usual natural route, and a cloudy drink hides any haze.

Call it orange soda. Fanta is a Coca-Cola trademark. A flavor house will list a copy as an "orange soda type". For a caffeinated take on the same profile, see Sunkist.
