Quick answer: A spice rating tells you how explicit the sexual content in a book is, usually on a scale of one to five chili peppers. One pepper means no or very mild sexual content (closed door or clean), while five peppers means frequent, graphic scenes. The scale is informal and not standardized, so different readers and authors use it slightly differently.
Quick facts
Common scale: 1 to 5 chili peppers
1 pepper: sweet or clean, no on-page sex
3 peppers: some open-door scenes
5 peppers: very explicit and frequent
No official standard; check the book’s own notes
If you read romance or romantasy, you have probably seen the chili pepper emoji. Spice ratings help readers pick books that match their comfort level. This guide explains the typical scale, related terms and how to find ratings.

What Do Spice Ratings Mean?
The spice rating is a shorthand for heat level. Romance readers developed it to avoid surprises. A book with one pepper is suitable for people who prefer a sweet story, while a five-pepper book has a lot of explicit content. Because it is a community tool, the exact meaning differs, but the general idea is shared.
The Typical Spice Scale
| Rating | Heat level | What to expect |
|---|---|---|
| 1 pepper | Sweet or clean | Kissing, no sex scenes; closed door |
| 2 peppers | Mild | Some sensual content, fade to black |
| 3 peppers | Medium | A few open-door scenes with moderate detail |
| 4 peppers | Hot | Several explicit scenes, strong language |
| 5 peppers | Very hot | Frequent, graphic scenes; possibly kinks |
Some readers also use a zero for no romance or no sex.
Open Door, Closed Door and Fade to Black
Open door means the sex scenes are shown on the page. Closed door means the characters kiss or embrace and then the door closes, leaving what happens to the imagination. Fade to black is a transition at the moment of intimacy. These terms often appear in book descriptions. Many readers pick closed door for a comfortable read at work or with a book club.
Where to Find Spice Ratings
Spice ratings appear in book reviews on Goodreads and The StoryGraph, in BookTok videos and on author websites. Some retailers show content tags. Because ratings are subjective, read several reviews. Authors in romance often list heat level in their blurb or on a content page, which is the most reliable source.
Spice and Content Warnings Are Not the Same
A spice rating is about sexual explicitness. Content warnings cover other topics, such as violence, abuse, death or mental health issues. A low-spice book may still contain heavy themes, and a high-spice one may be light. Check both when choosing a book. For dark topics, see our guide to dark romance.
Tips for Choosing by Heat Level
Decide what level you like and look for tags such as clean romance, sweet romance or steamy. If you share books with a friend or book club, discuss comfort levels first. For teens, consider young adult books, which rarely include explicit scenes, and read reviews. You can search for lists like clean romance to find sweeter picks.
Is the Spice Trend Controversial?
Some people like the system because it respects readers’ preferences. Others feel it reduces books to a single measure. Whatever your view, ratings help readers avoid unwanted surprises. They also show how romance fans have built their own tools to share information.
Examples of Heat Levels in Practice
A sweet romance might feature slow-burn longing and a first kiss at the end. A medium-heat romance could include one or two scenes with some detail, then return to the plot. A high-heat romance may have scenes in many chapters, with strong language and varied situations. Authors sometimes put a note at the start, such as this book contains open-door scenes. These notes let you choose a title that suits your comfort level.
Spice for Book Clubs and Gifts
If you are choosing a romance for a book club or as a gift, ask about preferences. Not everyone is comfortable discussing explicit scenes in a group. Look for low-spice options or books with fade-to-black scenes. When in doubt, choose closed-door romances, which are easy to share. Giving a book with a note about its heat level shows thoughtfulness.
Why Some Readers Avoid Spice Ratings
Not everyone likes the pepper system. Some readers feel it focuses too much on one aspect of a story, or they worry that ratings give away the plot. Others find the scale confusing since one person’s three might be another’s five. If you prefer not to use ratings, you can read author interviews, look for words like closed door or sweet in the description, or ask a friend with similar taste. The goal is simply to choose books that match what you want to read.
Using Heat Levels for Gifts and Clubs
When you buy a romance as a gift, think about the recipient. A sweet or closed door story is a safe choice for someone whose tastes you do not know. For a friend who loves steamy romance, ask which authors they like and choose one with a similar heat. In book clubs, share the heat level in the meeting invitation so that members can decide whether the pick suits them.
