How to compare caffeine on yerba mate labels

Some yerba mate packages state a caffeine amount. Some say only that the drink contains caffeine. Others list yerba mate as an ingredient without printing a milligram figure.

Those labels provide different amounts of information. They do not describe “high,” “low,” and “zero.” An unstated number is unknown, not zero—and it should stay blank in a comparison.

This guide first transcribes three current manufacturer pages, then gives you a blank worksheet for doing the same with two packages. It is designed around exact products, not a category average or a number borrowed from another drink.

Three packaged mate labels, transcribed side by side

The table below records only what the linked manufacturer page supported when checked on August 12, 2026. It does not rank the drinks, turn a package figure into a homemade-mate estimate, or carry one flavor's number over to another flavor.

This is a transcription comparison, not a controlled comparison of caffeine from yerba mate alone. The ingredient lists matter because all three products list a discrete caffeine ingredient or a caffeine-designated extract in addition to brewed mate. The printed total therefore should not be presented as if it came only from the brewed leaves.

The two 160 mg statements also should not be treated as identical records. Yachak attaches its number to 16 fl oz. CLEAN Cause attaches its number to a can, while the accessible page text did not expose the can's net volume. Keeping the original denominator avoids turning a neat-looking table into a false apples-to-apples claim.

First, separate presence from amount

FDA consumer guidance says that caffeine added to a packaged food as a stand-alone ingredient must appear in the ingredient list. When caffeine occurs naturally within an ingredient, the caffeine-containing ingredient may be listed instead. FDA also notes that many packaged foods and beverages voluntarily state how much caffeine they contain.

That creates three common label situations:

Presence wording and quantity wording answer different questions. Copy both exactly enough that you can tell which one the package actually provides.

The two-package worksheet

Use the package, its official product page, or a direct manufacturer response. Record the date because labels and formulas can change.

If the amount is not stated, write `not stated on label`. Do not fill the cell with a typical tea range, a search-result snippet, the number from another flavor, or a guess based on taste.

Match every number to its denominator

The FDA explains that Nutrition Facts information is usually based on one serving, while a package may contain more than one serving. Some packages also show information for the whole container. Serving size reflects customary consumption; it is not a recommendation for every person. FDA label guidance also says to check that serving sizes are the same before comparing label values.

Before comparing two printed caffeine amounts, make sure each number has all four parts:

1. the amount

2. the unit

3. the labeled serving size

4. the number of servings in the container

For example, a per-serving statement and a per-container statement are not aligned just because both use milligrams. The packaged examples above show the smaller version of that problem: `per 16 fl oz` and `per can` are not the same record when the can volume is unavailable. Copy the original basis first. Only calculate a whole-container total when the package provides enough information and the multiplication is unambiguous.

If the portions are not aligned, pause the ranking. The worksheet is still useful: it has shown exactly why the two numbers do not yet make a fair comparison.

Four gaps that should remain gaps

Do not estimate a missing caffeine value from:

• where yerba mate appears in the ingredient list
• the percentage of mate, unless a tested product value is also provided
• color, bitterness, leaf amount, or drink strength
• package size, cube count, or another product in the same category

Those details can describe the product or preparation. They cannot replace a product-specific caffeine measurement.

The same rule applies to homemade mate cubes. Brew method, leaf, water, cube size, and dilution all belong in the preparation record, but they do not create a tested milligram value. Until a finished formula is measured, a Yerba Melt per-cube number is unavailable.

When a label does not state the amount

An incomplete comparison does not need a forced winner. You can still compare what is visible:

• serving and container clarity
• ingredient wording
• preparation directions
• whether a numerical caffeine amount is stated
• whether that amount has a clear portion

If a product-specific number matters to you, FDA guidance suggests contacting the manufacturer. Record the response, the exact product, and the date rather than transferring the answer to a different flavor or package.

For a broader walkthrough of label fields, read how to read a yerba mate label. To compare packaged drinks without mixing serving sizes, use the yerba mate vs energy drinks label guide. And if you are wondering how a frozen format changes the serving question, start with what is frozen yerba mate?.

The useful future Yerba Melt label will tie a tested caffeine amount to a defined cube count and prepared serving. Until then, leaving the number blank is more informative than borrowing one that does not belong to the product.
