Our Commitment: Ingredients & Testing Standards

Tea is part of everyday routine for millions of people. It's the quiet moment in the morning, the break during a stressful afternoon, the ritual before bed. Delta North Tea believes that what goes in your cup matters, which is why we're serious about where tea comes from and how it gets to you.

Transparency means knowing the whole story, from soil to cup, and understanding that every decision we make prioritizes quality over shortcuts.

Where Our Tea Begins: Intentional Sourcing

Working directly with growers creates stronger partnerships than simply buying from suppliers does. The farms we partner with share our values about land health, sustainable growing, and producing consistent tea year after year.

From the Nilgiri Mountains

Our black teas and green varieties grow in Southern India's high-altitude gardens. The elevation and soil there naturally create leaves with complex flavors. Family-run farms manage these areas, viewing the land as something to care for long-term rather than something to squeeze for quick profits.

From the Volcanic Soils of Kagoshima

Japanese sencha and matcha grow in Kagoshima's volcanic region, where the soil's minerals concentrate in each leaf. Farmers there use methods that have worked for generations, growing tea alongside nature's seasons instead of fighting against them.

A Direct-Trade Approach

We work directly with growers, cutting out middlemen. This lets us see growing conditions ourselves and make sure farmers receive fair payment for their work. We know exactly where every batch comes from, from the first sprout to the dried leaf ready for your cup.

Our Uncompromising Testing Process

Trust requires evidence. We test our tea through multiple stages rather than relying on a single checkpoint. Each batch goes through careful examination before reaching customers.

Step 01

Verification at the Source

Before tea ships to us, our growing partners run initial tests. These first checks ensure leaves meet our standards, filtering out batches that fall short before they leave the field.

Step 02

Step 2: Our In-House Scrutiny

Before tea ships to us, our growing partners run initial tests. These first checks ensure leaves meet our standards, filtering out batches that fall short before they leave the field.

  • Pesticide Screening:

Gas Chromatography-Mass Spectrometry (GC-MS) checks for over 200 agricultural chemicals. This equipment detects trace amounts of residue that standard testing might overlook.

  • Heavy Metal Testing:

We measure lead, arsenic, cadmium, and mercury individually. These metals accumulate in soil and transfer to plants, so we verify that growing regions maintain acceptable levels.

  • Microbial Safety Checks:

Every batch gets tested for harmful bacteria including E. coli and Salmonella. If either is detected, the entire batch is rejected.

Step 03

Step 3: The Final, Independent Seal of Approval

We send finished product samples to an outside laboratory that operates independently from us. This third-party verification confirms that our internal testing actually worked as intended.

Your Right to Know

We maintain a Certificate of Analysis for every production batch we create. Request the specific test results for your tea anytime, and we'll provide the complete report with all measurements and lab details.

We pour this level of care into our testing so that you can pour your tea with complete peace of mind. Your trust is the most important ingredient we have.
