Grades, freshness
& sourcing

How to buy well and keep tea well. Grades mislead, freshness depends entirely on type, and storage quietly makes or ruins what you’ve bought.

Buying and keeping tea

Click through the sourcing and storage essentials:

The one rule that ties it together

Match your buying and storage to where the tea sits on the dial. Low-oxidation teas (green, light oolong, white) are about freshness — buy recent harvests, store airtight and cool, drink within a year. High-processing teas (pu-erh, aged white) are about patience — they improve with age and want airflow and stable humidity. The framework you built in the first half tells you exactly how to treat what you buy.

A note on the market

Prices, hype & staying grounded

A quick honesty note

Tea has its own hype and scarcity economics — aged pu-erh cakes and competition-grade oolongs can reach extraordinary prices, and the aged-pu-erh market in particular has speculation, fakes, and dubious storage claims. As with the whiskey course: a trained palate is the antidote. Buy from sellers who state origin and harvest, taste before you commit when you can, and let the cup — not the story or the price — be the judge. Specific prices and "grades" shift, so verify current specifics rather than trusting a number.

Consolidation
& final

One leaf, one dial, one cup you now control. From the plant to the processing to the brewing in your own hands — the whole arc, and where to take it next.

The whole arc, in one cup

Pick up any tea and you can now read its whole life. It began as one plant (Session 1); its type was set by how far it was oxidized (5) and when it was fixed (6); rolling and roasting shaped the rest (7); it landed somewhere on the dial — green, white, oolong, black, or the special case of pu-erh (8–13); its origin colored it (17–18); and finally you finished it at the kettle, where temperature, time, and ratio (15) decided whether the leaf’s potential reached the cup. That last step being yours is what makes tea unique among everything in this series.

Where to go next

Three good next steps

First, go deep on one type — pick oolong or pu-erh and taste widely within it; depth teaches more than breadth from here. Second, learn gongfu hands-on — a simple gaiwan transforms how much a good tea will show you. Third, keep a tasting log with brewing parameters noted, so you can reproduce the cups that worked. The palate and the framework are yours now; the rest is mileage.
