Tea is a crop before it is a product, and the crop keeps a schedule you can plan around. The best Darjeeling you will drink this year is picked in spring and at its peak by early summer. Japanese greens fade fast, so the difference between a May order and a September order is the difference between vivid and merely green. Roasted oolongs and aged pu'er, meanwhile, improve as the weather turns cold. Order with no thought for those rhythms and you pay fresh prices for tired leaf. Here is a working calendar: what to buy each month, when new lots land, and how to time the parcel itself.
Every tea has a harvest window. Spring greens from China and Japan are picked over a few weeks, processed within days, and are most aromatic within a few months. First flush Darjeeling is on the bush in late March and April; second flush follows in late May and June. Autumn oolongs come off the mountain in October. Then there is a small group of teas — roasted oolong, ripe pu'er, aged white — that you can buy almost any time, because time is part of the style rather than the enemy of it.
So the useful question is not "what sounds good today?" but "what is in season, and will it still be in season when the box reaches my door?"
That second half is where most drinkers get caught out. A tea can leave the estate at its peak and still land flat, because the weeks between picking and steeping are not neutral. Green tea is a clock that starts the moment the leaf is fired: the amino acids behind its sweetness and the volatile compounds behind that bright, cut-grass top note both fade with air, light and warmth. Buying the same sencha in April and in October is not buying the same tea, even if the label is identical.
New-crop tea reaches buyers in one of two ways. Air freight is quick and expensive; the leaf arrives within days of leaving the factory or estate. Sea freight is slower and cheaper, and a container can spend weeks at sea and more weeks in a warehouse. Black tea, roasted oolong and pu'er shrug that off. Delicate greens, shincha and lightly oxidized oolongs do not. If you are buying a spring green in April, ask how it is shipping. If the answer is "by sea, arriving in June," buy something that travels better.
The difference is easy to taste for yourself. Order 50 g of the same shincha from two sellers in the same week — one air-freighted, one sent by container — and brew them side by side. The air-freighted cup usually shows more sweetness and a longer finish. The sea-freighted leaf is often perfectly pleasant, just quieter, with the aroma sitting closer to the liquid.
Harvest date and packing date. A "best before" stamp tells you almost nothing about how long that tea has been sitting in a tin. Sellers who list the harvest year, or the week a lot was packed, are usually the ones handling stock properly — and the ones worth setting up a recurring order with.
If a seller cannot tell you when the tea was picked, they probably cannot tell you how it has been stored. Both answers matter more than the price.
Very little delicate green tea is coming off any hill in December, which is precisely why winter belongs to the teas that like time. Roasted oolong, shou pu'er, aged white, smoked black teas and the malty high-grown blacks of Assam and Yunnan all drink beautifully now. They are the cups that suit cold rooms, rich food and long evenings, and most of them improve rather than fade in the tin.
Winter is also pre-order season. The first Darjeeling invoices go out to regular buyers in January. Japanese shincha reservations open in February, sometimes earlier. Chinese green tea pre-orders run through late February and March. Putting your name down now means the tea is packed and shipped the week it is finished, rather than waiting for a warehouse to sort itself out.
Darjeeling starts picking in late March, and first flush lots move fast. These are the lightest, most floral teas the region makes — the muscatel of second flush becomes something closer to white flowers and green apple here. Air-freighted first flush appears in specialist shops from mid-April. If you want it, order in the first fortnight; by June the same lot is still good but noticeably calmer.
China's pre-Qingming greens, picked before the early April festival, are the other spring event. Mingqian Longjing and similar teas are prized for their tenderness, and they are usually sold before they are picked. April is also the last comfortable month for finishing last year's Japanese greens — after that, move them into cold storage or drink them up.
May is the best month of the year to buy green tea. Japanese shincha lands, Chinese spring greens are at their peak, and the shipping lag has not yet had time to do damage. Buy in smaller amounts rather than one large box, and keep everything sealed, cool and dark.
Second flush Darjeeling arrives in late May and June and is the rounder, more muscular style — deeper colour, stronger muscatel, better with milk if you take it. If you prefer a black tea that behaves like a black tea, this is your moment.
Summer is when cold-brewed tea earns its keep: two grams per 200 ml, cold water, six to eight hours in the fridge. Japanese greens, lightly oxidized oolongs and even second flush Darjeeling all do well this way.
It is also a good month for value. Older-crop greens get discounted, and if you drink quickly and don't mind a little lost aroma, this is where the bargains sit. Spring green oolongs are still lovely too. Just don't buy delicate greens in August expecting them to keep until Christmas.
Autumn oolongs — particularly Taiwanese high-mountain teas — are picked in October and are often considered the finest of the year, with a rounder body and a nuttier, more buttery finish than the spring picking. New lots start arriving in late October and through November.
September, meanwhile, is a good time to audit your cupboard. Anything delicate left from spring is past its best; anything roasted or aged is entering its best months.
New-harvest black teas from Nepal, Yunnan and Assam arrive, and this is also when much of the year's shou pu'er is pressed. Fresh shou can be a little sharp, so if you have the patience, buy it now and drink it in spring.
November is when many drinkers start building gift orders, and it is a sensible month for a mixed selection: one fresh black, one autumn oolong, and one aged tea for the winter shelf.
A seasonal subscription works only if it follows the harvest instead of the calendar page. A sensible pattern looks like this:
Keep quantities modest. A quarter-kilo of fading green is worse value than 50 g of a fresh one, and you will drink the smaller bag before the clock runs down.
Seasonal buying only pays off if the tea survives the interval. Greens and lightly oxidized oolongs belong in an airtight tin in the fridge — sealed, and brought fully to room temperature before opening, so condensation does not settle on the leaf. Roasted oolongs, blacks and pu'er want the opposite: airtight, dark, dry, room temperature, and well away from spices and coffee.
Aged white and pu'er are the exceptions to almost every rule here. They want air over the long run, and a little humidity, and they will happily sit through several winters. Buy them in autumn, drink them through winter, and let the rest keep improving.
