Sweet Rivalry: The Great Chocolate Debate

This weekend was the Crosstown Classic here in Chicago, sparking conversations about whether you're a Chicago Cubs fan or a Chicago White Sox fan. It's a classic city rivalry that always gets people talking.

A similar debate exists in the world of sweets: Milk Chocolate vs. Dark Chocolate. Just like Chicago baseball, everyone has a favorite—and they're not afraid to defend it.

Before I share my thoughts on milk vs. dark chocolate, let’s talk about the percentages you see listed on chocolate packaging. Let’s also clear up the difference between cocoa and cacao. These two terms can be confusing, depending on where you are and who’s using them. For example: is it called hot cocoa or hot chocolate (or is it cacao)?!?

Although cocoa and cacao technically have different meanings, when it comes to the percentage listed on chocolate bars, the terms are often used interchangeably.

So, what do these percentages actually mean—and how do they affect the taste?

In the simplest terms, the percentage refers to the amount of the chocolate that comes from

the cacao bean. This includes components like cacao mass (also called cocoa liquor or cacao liquor—not alcoholic), cacao nibs, and cacao butter.

Example: If a chocolate bar says 70% cacao dark chocolate, it means that 70% of the bar is made up of cacao—typically a combination of cacao mass (or liquor) and cacao butter. The remaining 30% consists of other ingredients that contribute to sweetness and flavor, such as sugar, vanilla extract, and other flavorings.

In general, the higher the cacao (or cocoa) percentage, the more intense—and often more bitter—the chocolate flavor.

Milk Chocolate vs. Dark Chocolate

When it comes to chocolate, milk and dark are the two most popular types—and each has its own loyal fans. The main difference between them comes down to the ingredients and, of course, the flavor.

Milk chocolate contains a lower percentage of cacao (usually around 10–50%) and includes added milk solids or milk powder, which gives it a creamy texture and sweeter taste. The added dairy softens the intensity of the cacao, making milk chocolate smooth, mellow, and easy to enjoy—even for those who don’t usually love strong chocolate flavors.

Dark chocolate, on the other hand, has a higher percentage of cacao—often 60% and above—and usually doesn't contain any milk solids (though some brands may include traces). The higher cacao content means less room for sugar, resulting in a richer, more robust chocolate flavor. It’s often described as bold, intense, or even slightly bitter, especially as the cacao percentage rises.

So which is better?

It really comes down to personal preference. If you prefer sweeter, creamier chocolate, milk chocolate is probably your go-to. If you enjoy a deeper, more complex flavor—and a bit less sugar—dark chocolate might be your favorite.

Just like the Crosstown Classic in Chicago baseball, the debate between milk chocolate and dark chocolate is timeless and full of passion. Everyone has their favorite—and just like loyal fans, chocolate lovers aren't afraid to stand by their choice. Whether you lean sweet and creamy or bold and bitter, there’s room for both on the chocolate roster.
