Tea Testing

Unbiased scientific analysis of loose tea, sachets, soluble and tea bags.

Tea is an aromatic beverage enjoyed hot or cold for more than 10 centuries. White tea, green tea, black tea, Oolong, Pu-erh, Matcha, and herbals all have distinct expectations for aromatic characteristics and taste attributes.

Quality Control

Scheduled testing to ensure adherence to specifications.

Calibration & Alignment

Verification of results from physical analysis and comparison of results between your sensory analysis and our sensory panel.

For projects that do not require physical analysis we offer options for cupping (CUP) and tasting (TST) only. Cupping (CUP) and tasting (TST) projects can be requested for green coffee, roasted coffee, soluble products, liquid products, and tea.

Physical Only Evaluations (PHYS)

For projects that do not require sensory analysis we offer options single test or multiple test physical evaluations. Physical Only Evaluation (PHYS) projects can be requested for green coffee, roasted coffee, soluble products, liquid products, and tea.

Sample-to-Standard / Degree of Difference (DoD)

Two different samples, a control and a variable, are evaluated side by side. Similarities and differences of various attributes are rated using both a numeric scale and sensory comments.
