Blackberry vs Raspberry: What's the Difference?
Short answer: Both are aggregate fruits in the genus Rubus. The giveaway is the centre: a raspberry slips off its stem leaving a hollow cup, while a blackberry keeps its white core inside. Raspberries are softer, more delicate, and tart-sweet; blackberries are firmer, larger, and deeper, sweeter-tart when fully ripe.
| 🖤 Blackberry | 💗 Raspberry | |
|---|---|---|
| Taste | Deep, winey sweet-tart with earthy, almost woodsy notes and gentle tannin; fully ripe berries are lush, underripe ones sour and astringent. Bigger isn't sweeter — black and dull-matte is. | Intensely aromatic — floral, winey, sweet-tart — with a delicate, collapsing texture and gentle seed crunch. Black raspberries are deeper and jammier; golden ones milder and honeyed. |

Blackberries and raspberries are both aggregate fruits: each berry is a cluster of tiny juicy drupelets, each with its own seed, fused around a central core. They’re close cousins in the genus Rubus, and the family resemblance is obvious - but there’s one foolproof difference.
When you pick a raspberry, it slides off its stem and leaves the white central plug (the receptacle) behind on the plant, so the berry is hollow like a little cap. A blackberry takes its core with it, so it’s solid all the way through. That’s why raspberries feel fragile and crush easily, while blackberries are firmer and hold up better.
In flavour, raspberries stay bright and tart with a floral note even when ripe, and they’re best eaten quickly or frozen. Blackberries ripen from red to deep purple-black and turn sweeter and richer as they go - a truly ripe one is soft, glossy, and dull-black rather than shiny. Both are interchangeable in jams, crumbles, and on cereal, but raspberries break down faster when cooked.
Frequently asked questions
How can I tell a blackberry from a raspberry?
Look at the middle. When you pick a raspberry it separates from its core and is hollow like a thimble; a blackberry keeps its core and is solid in the centre. Blackberries are also usually larger, glossier, and darker.
Are they the same plant?
They're close relatives - both are brambles in the genus Rubus - but different species. Many hybrids exist between them, such as the loganberry and boysenberry.
Which is sweeter?
It depends on ripeness, but fully ripe blackberries tend to taste sweeter and deeper, while raspberries keep a bright, tart edge even when ripe.
