Dolci Orange: A Happy Accident with a Chocolate-Coloured Twist
If you grow your own navel orange tree, you probably think you know what a navel is supposed to look like. Most navels have bright orange skin, a little “belly button” at the base and a good balance of sweet and tart flavours. But there’s one Australian navel variety that breaks all the rules: the Dolci orange. This bronzed, extra-sweet navel started life as a random mutation on one branch of an ordinary orange tree. Learn more about this unusual orange that ended up becoming a sought-after variety exported around the world.

How the Dolci Orange Was Discovered
The story of the Dolci orange starts the way a lot of great citrus discoveries do, by someone noticing that one branch of a tree was behaving strangely.
Sometime around 2009–2010, in an Australian navel orange orchard near Leeton, in the Murrumbidgee Valley in New South Wales, an orchard worker spotted a single branch producing fruit that looked completely different from the rest of the tree. Instead of the usual bright orange skin, this branch was covered in oranges with an unusual bronzed, greenish-brown tinge.
This is what’s known as a “bud sport” or limb mutation. It’s a naturally occurring genetic change that happens spontaneously in a small part of a plant, with no cross-breeding or genetic modification involved. It’s actually how quite a few well-known citrus varieties came about. This includes the navel orange itself, which is a mutation from a plantation in Brazil.
As navel oranges are seedless, the only way to reproduce this new variety was to take cuttings from that one mutated branch and graft them onto rootstock. Every Dolci orange tree growing today is a direct descendant of that single, accidental branch.
From Orchard Curiosity to Commercial Variety
Finding an odd-looking orange is one thing. Deciding it’s worth growing commercially is another. Once growers tasted the fruit from that mutated branch, they realised they had something special. This orange was noticeably sweeter and lower in acid than a standard navel orange.
That’s actually where the name comes from. “Dolci” means “sweet” in Italian, chosen to highlight the fruit’s unique sweet flavour.
The variety is protected by Plant Breeder’s Rights (PBR) in Australia, and its propagation is managed under licence. In practical terms, this means growers need permission to propagate and sell Dolci trees or fruit commercially. It’s not a variety you can simply pick up as a tree at your local nursery (more on that below).
Dolci oranges made their way into Australian supermarkets around 2016, and since then they’ve also been exported overseas. In China they’ve become known as “chocolate oranges” thanks to their distinctive brown-tinged skin. They’re also sometimes marketed wrapped in foil just like a chocolate.
What Does a Dolci Orange Look Like?
The biggest giveaway that you’re holding a Dolci orange is the skin. Instead of the bright, glossy orange you’d expect, it has a bronzed, almost chocolate-brown tinge. Dolci oranges are sometimes described as looking like they’ve been dipped in cocoa. It still has the classic little “navel” at the base. In size and shape it’s very similar to a standard Washington navel orange.
Cut one open, though, and the inside looks much more familiar. The flesh and juice are a typical orange colour. It’s really just the skin that makes this variety stand out.
What Does a Dolci Orange Taste Like?
Flavour is where the Dolci really earns its name. Compared to a standard navel, it’s:
- Sweeter, with noticeably lower acidity
- Very juicy, with consistently high juice content
- Similar in texture to a Washington navel, with firm, easy-to-separate segments
- Still full of genuine orange flavour. The lower acid doesn’t mean it lacks flavour.
If you’ve ever found a standard navel orange a little too sharp for your taste, or you’re feeding fussy kids who turn their nose up at ‘sour’ oranges, the Dolci could be ideal.
How to Use Dolci Oranges in the Kitchen
Because it’s so sweet and low in acid, the Dolci orange is perfect in dishes where you don’t want an overpowering citrus tang.
- Eating fresh: its mild sweetness makes it a great snacking orange, especially for kids or anyone who finds regular navels too tart.
- Salads: try it anywhere you’d use orange segments without wanting a sharp bite, like a fennel and orange salad, or an orange and olive salad. Try Dolci in one of our orange salad recipes.
- Baking and desserts: The natural sweetness means you can often ease back on added sugar. It’s a lovely choice for an orange cake, and could easily be swapped for Cara Cara oranges in our orange olive oil cake. Dolci oranges are also a great choice for a citrus fruit salad. Or try Dolci in a citrus curd with a softer edge.
- Fresh juice: Being naturally sweet, fresh-squeezed Dolci juice is perfect as it is without any need for added sweetener.
- Garnishes and citrus displays: The bronzed skin is genuinely striking. Dehydrated Dolci slices or candied peel make a beautiful addition to a citrus board, wreath, or garland if you love using citrus in your home decor as much as I do.
Can You Grow a Dolci Orange Tree at Home?
This is the question I get asked most about unusual varieties like this one. And unfortunately, the answer for Dolci is “probably not, or at least not easily.” Because it’s a licensed, PBR-protected variety, propagation is controlled. So you won’t typically find Dolci trees for sale at a regular nursery the way you would a Eureka lemon or a standard Washington navel.
The good news is you don’t need to grow your own to enjoy Dolci oranges. Keep an eye out for them at your greengrocer, specialty fruit shop or farmers market, especially during navel orange season. And if you do want a similar low-acid, extra-sweet eating experience from a tree you can grow, a standard Washington navel is the closest relative and widely available.
