Organic Peppermint Caffeine Free Tea from Taylors of Harrogate. For centuries mint has been used as an aid to digestion. The natural peppermint leaves have a delightful fresh, clean flavour that make a soothing infusion at any time of the day. We buy organically grown peppermint for purity and flavour. For the perfect cup add freshly boiled water and infuse for 3-4 minutes. Serve just as it is or sweetened with sugar or honey.
