ISO 3103:2019 Tea — Preparation of Liquor for Use in Sensory Tests

Tea is both a cultural heritage and a global commodity, consistency in taste and quality matters more than ever. Enter ISO 3103:2019, a specialized international standard that sets the groundwork for standardized tea tasting. From ensuring uniform flavour evaluations to promoting industry-wide trust, this standard plays a pivotal role in maintaining tea quality worldwide. At Pacific Certifications, we help tea producers to ensure their alignment with this globally recognized standard through robust auditing and certification services.

What is ISO 3103:2019?

ISO 3103:2019 is an international standard published by the International Organization for Standardization (ISO). It defines a precise method for brewing tea liquor, intended specifically for sensory evaluations, such as taste tests and quality assessments. The goal is to remove subjectivity from the tea tasting process by establishing consistent brewing parameters across different testers, locations, and timeframes.

The standard outlines everything from the weight of dry tea leaves, the volume and temperature of water, to the brewing duration and type of vessel used. Ultimately, ISO 3103 ensures that tea professionals and laboratories can fairly and accurately compare the sensory properties—taste, aroma, and appearance—of different teas.

Why ISO 3103:2019 Matters for the Tea Industry

Tea is more than just a beverage—it’s a global industry valued at over $200 billion. Variability in taste assessments can lead to disputes, misbranding, or diminished consumer trust. That’s why ISO 3103:2019 is vital:

• Sensory Testing: Creates a uniform method to prepare tea for unbiased evaluation.
• Repeatability: Minimizes inconsistencies across tests.
• Consumer Trust: Encourages quality assurance in products labeled as premium.
• Global Trade: Harmonizes testing protocols across countries.
