Tetley is committed to sustainability and has worked with the Rainforest Alliance for many years towards our goal of buying all our tea from Rainforest Alliance Certified™ farms. Our Redbush blends have been sourced exclusively from certified producers for five years. However, due to a continued period of very poor rainfall in the Cedarburg mountains in South Africa (the only place in the world where Redbush is grown), we have been unable to buy enough Rainforest Alliance Certified™ Redbush to cover our demand. For a short production period between the 1/4/17 to 15/5/17 we will be unable to guarantee that our Redbush products contain Rainforest Alliance Certified™ Redbush. We would like to apologise for this situation and expect to be back to normal from the middle of May 2017.
