Black and green tea contain caffeine because both come from the tea plant. Rooibos contains no caffeine by nature, while a herbal blend depends on its complete recipe.

How much caffeine is in a cup of tea?

Health Canada lists an average of 30–50 mg for 237 mL of brewed black or green tea. It groups the two together; this reference does not establish that black tea always contains more caffeine than green tea.

Moodvera has not supplied laboratory caffeine measurements for these products. The reference range should not be presented as the measured amount in a serving of Jasmine Flow or Blue Fog.

What changes caffeine in the cup?

Plant variety, leaf quantity, water temperature, steeping time and cup size all affect the final amount. General ranges are not laboratory results for an individual Moodvera product.

  • Moon Calm: rooibos and herbs; caffeine-free.

Does a shorter steep remove caffeine?

A shorter steep may extract less caffeine, but it does not turn green or black tea into a caffeine-free drink. Choose a naturally caffeine-free recipe when that distinction matters.
