Teabacco does in fact contain caffeine due to the black tea leaves we use naturally containing caffeine as part of the leaf. Aside from the amount of caffeine found in our black tea leaves, which is similar in level to your regular loose-leaf black tea you can buy from the supermarket, we do not add any extra caffeine to our recipe. Also to note, since Teabacco uses natural black tea leaves, you will also find several chemicals that naturally occur in the black tea leaf itself, such as polyphenols, flavanols, catechins, tannic acid, theaflavins, proteins & amino acids, carbohydrates, pectins, and fiber.
