Big Tea

Big Tea is a function-first tea brand built on the belief that tea should do more than taste good, it should be felt. Every blend has a clear purpose, using precisely dosed ingredients that are given the space to properly infuse and deliver their full potential. The result is a range of functional tea blends that support stress management, calm focus and better sleep.

Each plant-based tea bag contains over three grams of large-cut botanicals and whole tea leaves, never dust or filler, allowing flavour and function to unfold naturally in every cup.
Sourcing matters just as much as formulation. Big Tea works directly with single-origin growers, from Colombia’s only tea garden in the Andes to smallholder cooperatives in the Nepali Himalayas, ensuring farmers are paid fairly and supply chains remain transparent.

With clean formulas, biodegradable bags and a focus on real-world benefits, Big Tea makes functional tea accessible, effective and deeply satisfying, supporting everyday balance through better brews.

Big Tea is a function-first tea brand that believes tea should do more than taste good, it should be felt. Each blend is made with precisely dosed, whole-leaf tea and large-cut botanicals designed to support everyday needs like stress management, calm focus, and better sleep. No dust, no filler—just clean, purposeful blends that deliver real benefits in every cup.

Because ingredients need space to work. Big Tea’s oversized, plant-based tea bags hold over 3 grams of whole leaves or large-cut botanicals, nearly double the industry standard. This allows the ingredients to properly unfurl and infuse, unlocking deeper flavour and more effective functional benefits. It brings the quality of loose-leaf tea to the convenience of a tea bag.

Big Tea works directly with single-origin growers and smallholder cooperatives, from Colombia’s only tea garden to farms in the Nepali Himalayas. This ensures fair pay, transparent supply chains, and consistent quality. Their tea bags are fully biodegradable and packaging is recyclable—because better tea should support both people and the planet.
