Etymology: "Before the Rain"

The word Ujeon (우전) literally means "before the rain". It refers to the Gogu (곡우) period of the Korean solar calendar, the "rain of grains", which falls around April 20th. The Gogu rains warm the soil, accelerate leaf growth, and mark the end of the most precious harvest window.

Everything picked before these rains is Ujeon. Everything picked after belongs to the subsequent grades: Sejak, Joongjak, Daejakcha. The boundary is strict. A few days' difference separates the rarest grade from the others. It is this temporal rigor that makes Ujeon not just a tea, but a moment captured in a leaf.

A Goldsmith's Harvest

The Ujeon harvest cannot be mechanized. Each bud is picked by hand, one by one. The artisan picks only the very first shoot: a tiny, still-closed bud and its first two leaves, so small they fit on a thumbnail.

It takes between 4,000 and 5,000 of these shoots to produce just one kilogram of dry tea. An experienced picker harvests approximately 1.5 kg per hour of work. The harvest window lasts an average of ten days, sometimes less if spring is fickle. Some years, a late cold snap or premature rains shorten this period even further.

This rarity combined with the intensity of the work explains the value of grand cru Ujeon. This is not manufactured luxury: it is the natural rarity of something that can only be produced once a year, for a few days, by hand.

Why Winter Forges Ujeon

The aromatic superiority of Ujeon over later harvests is explained by a precise biological mechanism. Throughout winter, the tea plant slows its growth but continues to synthesize L-theanine, the amino acid responsible for umami sweetness, without converting it into catechins (bitter). When spring returns, the buds therefore contain an exceptional concentration of L-theanine accumulated over five months.

In parallel, the cold pushes the roots to explore deep into the soil to draw the minerals necessary for survival. This winter root exploration enriches the mineral profile of spring tea. And the natural sugars, produced as antifreeze by the plant during winter, are concentrated in the first buds. The result: an intense natural sweetness, almost creamy, without added sugar.

Tasting Notes

How to Prepare Ujeon

Ujeon is the tea that least tolerates water that is too hot. Its exceptional concentration of L-theanine is the first victim of excessive temperature.

Water: 60 to 68°C maximum. This is an absolute requirement. Above 70°C, umami compounds begin to degrade and a slight bitterness may appear.

Quantity: 2 to 3g per 100ml. Less than for an ordinary tea: the leaves are highly concentrated.

Duration: 45 to 60 seconds for the first infusion. Slightly increase the temperature (5°C) and duration (30 seconds) with each subsequent steeping.

Vessel: a white porcelain or glass bowl to admire the pale, translucent liquor. Preheat the bowl with hot water before pouring the tea into it.

Steepings: 4 to 6 successive infusions. Each steeping reveals new nuances: pure umami on the first, nutty notes on the second, slight minerality on the subsequent ones. Do not discard the leaves after the first cup.

Gifting Ujeon

In Korea, Ujeon is the most prestigious tea gift there is. To offer it is to communicate: "you deserve the rarest." For important occasions, such as promotions, retirements, or major birthdays, Ujeon expresses better than words the esteem and consideration you have for the other person.
