How to Cup and Taste Tea for Blend Evaluation

A pouch of tea can look correct on the shelf and still taste nothing like the sample a buyer originally approved. Grammage, leaf source and water can all shift slightly between a first sample and a production run, and the only way to catch that reliably is a tasting method that does not depend on memory or mood. Cupping is that method: a short, structured routine that turns "this tastes about right" into a scored, repeatable comparison. It works whether the sample in front of you is a single-origin herbal infusion, a fruit blend, or a client's own recipe being packed under contract, and it takes no special equipment beyond a kettle, a set of matching cups and a timer.

Why a fixed method matters more than a good palate

Even an experienced taster drifts without a fixed procedure — the second cup of the afternoon is judged against the first, not against a stable reference. Cupping removes that drift by fixing every variable except the tea itself: same water, same dose, same steep time, same cup. Once the method is fixed, differences in the cup can be attributed to the tea, which is exactly what a buyer approving a blend, or comparing this month's production run to last month's, actually needs.

Building a simple cupping station

You do not need a laboratory to cup tea properly, just consistency. Line up identical white or light-coloured cups, one lid or saucer per cup to trap aroma, a single kettle so every sample gets water from the same source, and a timer visible to everyone tasting. If you are comparing a pouch sample against loose leaf, or comparing several suppliers side by side, lay the samples out in the same order every time so nothing gets tasted twice or skipped. Number or code each cup rather than labelling it by supplier name, so the tasting stays blind and the score reflects the tea rather than an assumption about who sent it.

Getting water temperature and steep time right

Temperature and time are the two variables most likely to be judged by guesswork rather than measurement. As a general starting point, black tea, herbal and fruit infusions are typically cupped close to a full boil, while green tea is cupped somewhat cooler to avoid pulling out excess bitterness. Steep time is commonly set around four to five minutes for a standard cupping infusion, timed on a clock rather than by taste, so that every sample in the session is judged under identical conditions.

Reading the dry leaf and the aroma

Before any water touches the leaf, look at particle size and consistency in the pouch or tin — uneven fragments or excessive dust can signal a production issue worth flagging on its own. Smell the dry leaf first, then smell again as soon as the infusion is lifted or the bag removed; the wet-leaf aroma sits much closer to what the finished cup will actually deliver, and it is often the moment a fault first becomes obvious.

Judging liquor colour and clarity

Hold each cup against a plain white surface and note colour depth alongside whether the liquor runs bright and clear or looks hazy. For herbal and fruit blends especially, cloudiness or visible sediment is worth recording, since it can point back to fine particulate that a production run should be screening out. Colour is a supporting signal rather than the final word — a cup can look exactly right and still taste flat.

Tasting and scoring the liquor

Draw a small amount of liquor across the tongue with a short slurp so it aerates and reaches the full range of taste receptors, then score sweetness, bitterness, astringency, body and finish on a simple numeric scale you use consistently. Spit rather than swallow once you are past two or three samples, since accumulated caffeine and sugar both dull the palate faster than most tasters expect. A neutral cracker or a sip of plain water between cups resets the palate and keeps the fourth or fifth sample as fair as the first.

From cupping sheet to approval decision

A cupping session only earns its keep once the scores are written down and compared against a reference — either the previously approved sample or an agreed target profile. That written sheet becomes the record a buyer can point to later if a production batch needs checking against what was originally signed off, which matters whenever a blend is being run under contract for a private label or bagged to a client's own recipe. TeraVella runs sample rounds this way for its contract tea bag production, so an approval decision made at the cupping table still holds once the pouches reach the shelf.
