You know white sugar and brown sugar — but what about black sugar?
It sounds like a darker, trendier version of brown sugar, but is that really the case?
Quick answer:
No, black sugar and brown sugar aren’t the same.
Black sugar is less processed, keeping all of its natural molasses, while brown sugar is usually refined white sugar with molasses added back in. That’s why black sugar has a deeper flavor and slightly more minerals.
In this post, we’ll break down what sets them apart, how each one is made, and whether one is actually better for you.
What Exactly Is Black Sugar?
Black sugar isn’t something you’ll usually find in a regular supermarket — it’s much more of a specialty item. It’s especially popular in Japan, where it’s known as kokuto and has been made in Okinawa since the 17th century.
Like white and brown sugar, black sugar comes from sugarcane — but it’s far less processed.
Here’s how it’s made:
- Fresh sugarcane is crushed to extract the juice (this is done mechanically with machines).
- The juice is slowly boiled for hours, during which impurities are removed naturally as part of the cooking process.
- Once it’s thick and concentrated, the dark syrup is poured into trays and left to cool and harden naturally into blocks.
Unlike regular brown sugar, nothing is removed during this process — all of the natural molasses stays in the sugar. This gives black sugar its deep flavor, darker color, and slightly higher mineral content compared to more processed sugars.
Thanks to Okinawa’s rich soil and climate, the black sugar produced there is considered exceptionally high quality — different from versions made elsewhere.
Black Sugar vs Brown Sugar: What’s the Difference?
Although black sugar and brown sugar both start from sugarcane, how they’re processed makes all the difference.
Here’s a quick breakdown:
| Black Sugar | Brown Sugar | |
|---|---|---|
| Processing | Boiled down once; impurities removed naturally; no refining | Boiled sugarcane juice, then refined into white sugar and molasses added back |
| Molasses Content | All natural molasses remains | Molasses is controlled and added back artificially |
| Flavor | Rich, deep, slightly bitter | Sweet, mild molasses flavor |
| Texture | Dense and hard (block or granules) | Soft and moist |
| Nutrient Content | Slightly higher in minerals like calcium, potassium, iron | Lower in natural minerals due to refining |
Key differences:
- Black sugar keeps all of its original molasses, giving it a richer flavor and more minerals.
- Brown sugar, especially the commercial kind, is white sugar with molasses added back, giving it a lighter taste and softer texture.
Are Black Sugar and Brown Sugar Ever the Same?
In most cases, black sugar and brown sugar are not the same — mainly because brown sugar is usually refined white sugar with molasses added back.
However, there are exceptions.
In some parts of the world, like Taiwan, traditional brown sugar is made without removing the natural molasses during production.
When brown sugar is made this way — directly from boiled sugarcane juice without heavy refining — it’s essentially the same as black sugar.
Bottom line:
- Factory-made brown sugar = not the same as black sugar.
- Traditional brown sugar (like in Taiwan) = almost identical to black sugar.
Is Black Sugar Healthier Than Brown Sugar?
Slightly, but only in small ways.
Black sugar keeps all of its natural molasses, which means it has a bit more minerals like calcium, potassium, and iron compared to regular brown sugar.
However, the difference isn’t huge — and both are still high in sugar and should be eaten in moderation.
Bottom line:
Black sugar is a little less processed and slightly more nutritious, but it’s still a treat, not a health food.
Final Thoughts
While black sugar and brown sugar share some similarities, they’re not exactly the same.
Black sugar is less processed, richer in flavor, and holds onto a little more of its natural nutrients — but at the end of the day, both are still forms of sugar. Whether you prefer the deep, bold taste of black sugar or the lighter sweetness of brown sugar, the key is to enjoy them in moderation.
