1. Look for tea in the blend
Green, black, white and oolong tea come from Camellia sinensis. NCCIH notes that tea contains caffeine, while herbal infusions are made from other plants. A hypothetical blend of “mint with green tea” therefore needs a different check from a product whose ingredients list contains only mint.
Read the entire list, not just the largest lettering. Mark tea names and unfamiliar ingredients for clarification. FDA also lists yerba mate and guarana as caffeine-containing ingredients. Do not assume that adding flowers or fruit makes the other ingredients irrelevant; keep the exact product variety and manufacturer in your notes.
2. Distinguish decaf from caffeine free
Decaf describes a product from which most caffeine has been removed; it does not automatically mean that none remains. FDA distinguishes these products from drinks that naturally contain no caffeine. When translating a foreign label, keep the original wording beside your note so this distinction is not lost.
When comparing two packets, record the ingredients and the manufacturer’s statement separately. Do not write “0 mg” if the packet gives no such value. A missing number is missing information, not a confirmed zero. If the specific amount matters to your choice, ask the manufacturer about that exact product variety.
3. Read the number with its unit
If the manufacturer provides a caffeine amount, check what it refers to: dry product, 100 ml of drink or a prepared serving. Do not compare these figures without a common basis. Copy the serving size and preparation method to which the statement applies. A number without that context explains very little.
FDA notes that the actual amount can vary with growing conditions, processing and preparation. Do not calculate an exact amount from color, bitterness or a general table for another tea. A home record describes the packaging and your preparation; it is not a substitute for laboratory measurement.
4. Make a short product record
Five fields are enough: name and variety; complete ingredients; caffeine statement; amount with its unit, if available; source and date of the information. Photos of both sides of the packet help distinguish similar blends later. When changing products, check the details again instead of copying the previous record.
When shopping, compare the same fields for two products. Where information is missing, leave a blank and write down a question for the manufacturer. The Napar atlas helps organize plant names, while the label-reading guide covers other packaging details. A plant’s inclusion in the atlas does not certify that a blend is caffeine free.
Frequently asked questions
Is the word “herbal” enough to identify a caffeine-free blend?
No. Check the complete ingredients and statements for that particular product, especially if the blend also contains tea or other caffeine sources.
Can I enter zero when the manufacturer gives no amount?
No. Record the amount as not provided. Missing information and a confirmed zero are different things.
