Selective Partnerships
We source only from estates that meet our strict standards. Trusted partners hold certifications such as Rainforest Alliance and Fairtrade and are chosen for their sustainable practices and crop integrity. Fewer than 5% of the world’s tea gardens meet the Newby threshold for quality, ethics and environmental care.
Expertise & auditing
Our sourcing team works directly with growers, assessing quality through samples and documentation. Every partner is subject to a rigorous audit of certifications, farming practices and ethical compliance before any tea is approved.
Our partners' certifications:
Quality & safety
Every tea is tested by Eurofins, a world-renowned laboratory, for over 650 contaminants, including fluoride. This rigorous process ensures every cup is pure, safe and of the highest quality.
Transparency & traceability
Through long-standing partnerships and a global supply network, we maintain traceability from garden to distribution, ensuring every cup reflects integrity at every stage.
We never compromise on taste
Each batch is assessed by our Founder and Master Tea Taster, together with a global team of experts. Only teas with outstanding balance, aroma and flavour are awarded the Newby name.
