Cold Brew Ingredients: What's Actually in Your Can

"Cold brew" describes how coffee is brewed, not what else goes in the can or bottle. Some black cold brews list only coffee and water. Others add natural flavor, chicory root fiber, phosphates or nitrogen. This guide shows a few labels as each brand publishes them and explains what the common ingredient terms mean.

What the Ingredient Terms Mean

Natural flavor

"Natural flavor" is a defined term in US food labeling rules. Under 21 CFR 101.22, it covers essential oils, extracts, distillates and similar products derived from plant or animal sources "whose significant function in food is flavoring rather than nutritional." The same rule lets a label declare these simply as "natural flavor" or "artificial flavor," so the ingredient list won't tell you which specific compounds were used.

Added Sugars

The Nutrition Facts label shows Total Sugars and, separately, Added Sugars. The FDA explains that Added Sugars include sugars added during processing, and sets the Daily Value for added sugars at 50 grams per day on a 2,000 calorie diet.

Other ingredients

Chicory root fiber, phosphate salts and nitrogen each appear on at least one label above. The ingredient list names them but doesn't say why each was added. If that matters to you, the brand's customer service is the place to ask.

Caffeine

The FDA says caffeine must be listed as an ingredient when it's added, but stating the amount is voluntary (FDA). In black coffee, caffeine comes from the coffee itself, so it doesn't appear as a separate line. FDA says up to 400mg a day is an amount not generally associated with negative effects for most healthy adults.

What to Look For on a Cold Brew Label

  • Read the ingredient list. It tells you more than the front of the package.
  • Count the ingredients. And know what each one is.
  • Check the Added Sugars line. Grams per serving, and servings per container.
  • Look for a caffeine figure. It's voluntary, so not every label has one.
  • Check the serving size. A large bottle may hold several servings.
