Bittersweet vs semisweet chocolate
Legally, nothing — they share a floor in the US standards. In practice, whichever a maker calls the less sweet end of their own range.
Why these get confused
Readers assume bittersweet is a defined step darker than semisweet. It is the same legal category under a different name, and one company's bittersweet may be sweeter than another's semisweet.
Side by side
| Bittersweet | Semisweet | Why it matters | |
|---|---|---|---|
| Legal minimum | 35% chocolate liquor under the US standards. | The same 35%, from the same standard. | There is no legal boundary between them at all. The distinction is a manufacturer's marketing decision. |
| Typical cacao content | Usually 60–85%. | Usually 50–65%. | The convention holds within a maker's range and not across makers. The printed percentage is the only reliable guide. |
| What recipes assume | A darker, less sweet chocolate; common in more serious American baking. | Around 55–60%; the default for cookies and anything involving chips. | A European reader substituting a 70% bar for 'semisweet' removes roughly twelve percentage points of sugar. |
| Outside the US | Used loosely as a synonym for dark chocolate. | Used loosely as a synonym for dark chocolate. | Neither word is a standardised name in the EU, where 'chocolate' is the defined term. |
Choose Bittersweet when
When you want the darker end of a maker's range, or when a recipe specifies it and prints a percentage you can check.
Choose Semisweet when
When following an American recipe that says only 'semisweet', which is assuming around 55–60%.
When the distinction does not matter
Substituting one for the other in most bakes. The difference between them is generally smaller than the difference between either and a 70% European bar.
