Professional Tea Tasting & Cupping Process
Tea tasting is an established organoleptic discipline central to commercial tea procurement. Operating from our dedicated tea tasting desk in Siliguri, Byahut Tea Company conducts sensory evaluation across hundreds of candidate auction and garden invoices weekly, benchmarking liquor color, briskness, and leaf bloom for commercial wholesale buyers across India.
The Standard Cupping Parameters
- • Leaf Measure: Exactly 2.80g weighed on digital precision scales.
- • Water Volume: 100ml freshly boiling filtered water.
- • Steeping Time: Exactly 5 minutes (300 seconds) in covered white porcelain pots.
- • Evaluation Vessel: Standard white porcelain tasting bowl with serrated lip for draining.
- • Tasting Protocol: Initial hot sip for volatile aromatics followed by cooled tasting for body and creaming down.
The Eleven Sensory Evaluation Criteria
Standard sensory dimensions examined during professional organoleptic tea evaluation.
| Parameter | Evaluation Stage | Desirable Quality Traits | Commercial Significance |
|---|---|---|---|
| 1. Dry Leaf | Pre-infusion Visual Review | Clean, well-sorted, dark sheen, tippy golden buds, uniform particle cut, absence of fiber | Determines visual packet appeal and packing density consistency |
| 2. Infused Leaf | Post-infusion Spent Leaf | Bright coppery-red color, even particle hue, fresh aromatic nose, clean fermentation | Confirms correct factory fermentation and drying temperatures |
| 3. Liquor | Bowl Appearance | Bright, luminous, sparkling ring around bowl, freedom from turbidity or sediment | Key for consumer visual appeal and clear iced tea clarity |
| 4. Aroma | Warm Leaf & Cup Nose | Fresh, pure, distinctive fragrance (floral, malty, vegetal); zero sour or smoky notes | Detects volatile freshness and guards against storage taints |
| 5. Colour | Optical Depth | Deep copper-red in Assam CTC, bright amber in Dooars, golden champagne in Darjeeling | Provides immediate visual cue of tea origin and brew intensity |
| 6. Strength | Palate Extraction | Rich extract density, heavy tea solids, capacity to hold milk without diluting character | Essential parameter for breakfast chai and milk tea blends |
| 7. Briskness | Palate Sensation | Lively, refreshing bite on tongue margins; live and stimulating astringency | Defines the invigorating morning wakefulness of commercial tea |
| 8. Body | Mouthfeel & Viscosity | Substantial, viscous weight on the palate; full-bodied roundness | Distinguishes premium thick teas from thin, watery candidate lots |
| 9. Flavour | Taste Notes | Origin-characteristic flavor notes (caramelized malt in Assam, Muscatel in Darjeeling) | Determines consumer taste preference and brand flavor identity |
| 10. Aftertaste | Finish | Clean, pleasant, lingering sweetness after swallowing; zero harsh lingering bitterness | Ensures enjoyable drinking experience and repeat consumer purchase |
| 11. Consistency | Benchmark Comparison | Side-by-side sensory alignment against retained reference counter-samples | Guarantees uniform cup profile across repeat consignments throughout the year |
The Five Steps of the Siliguri Cupping Protocol
Standard sequence followed during weekly auction and estate catalogue evaluations.
Dry Leaf Review
Tasters examine the dry leaf on white evaluation trays under consistent natural lighting to evaluate bloom, particle size distribution, and twist.
Weighing & Steeping
2.80g of tea is weighed into porcelain cupping pots, infused with 100ml freshly boiling water, and steeped for exactly 5 minutes with closed lids.
Spent Leaf Aroma
Leaves are drained onto inverted lids. Tasters inspect the bright coppery color and evaluate the aroma for freshness, maltiness, or taints.
Aspiration Slurping
Liquor is slurped vigorously from tasting spoons to aerate the palate, coating olfactory receptors to measure briskness, strength, and flavor notes.
Benchmark Matching
Candidate lots are compared side-by-side with retained client reference samples to verify that color, body, and taste match contractual benchmarks.
Frequently Asked Questions on Professional Tea Tasting
What is the ISO 3103 protocol in tea tasting?
ISO 3103 is an internationally recognized sensory testing method specifying standard porcelain pots, exact water-to-leaf ratios (typically 2.8g of tea per 100ml of freshly boiling water), and a precise 5-minute steeping period. It provides a standardized baseline for comparing commercial tea lots.
Why do tea tasters slurp the liquor vigorously?
Slurping liquor draws tea into the mouth along with a stream of air. This aerates the liquid across the tongue and sprays fine droplets into the retro-nasal cavity, allowing tasters to simultaneously register aroma, briskness, astringency, and subtle taste nuances.
What does 'Creaming Down' mean in tea cupping?
'Creaming down' describes the cloudy, opaque precipitation that develops as a concentrated cup of strong black tea cools down. It reflects a high natural density of theaflavins and caffeine, indicating a rich, brisk, and full-bodied cup.
Can commercial buyers request tasting counter-samples?
Yes. Commercial tea buyers and packagers can submit target cup specifications to our Siliguri desk, and we will prepare and dispatch matching counter-samples with detailed organoleptic tasting notes.
