Yuzu tea is not a brewed leaf tea at all. It is a caffeine-free citron drink made by stirring a spoonful of sweet, marmalade-like yuzu preserve into hot water, giving a bright, tart-sweet, floral and honeyed cup that people reach for in the cold season across East Asia. Known in Korean as yuja-cha, it leans on the fragrant yuzu (yuja) citron rather than the tea plant, so the word "tea" here means a warming infusion, not a Camellia leaf.
If you have ever seen a jar of golden, jam-like citrus peel in an Asian grocery and wondered what to do with it, this is the answer: a spoon of that preserve plus hot water is the whole drink. Below is what it is, why it carries two names, how it tastes, and how to make it at home.
What yuzu tea actually is
At its heart, yuzu tea is a citrus preserve rather than a steeped leaf. Thin-sliced yuzu citron — peel, pith and all — is layered with honey or sugar and left to macerate until it turns into a loose, syrupy marmalade. Scoop a little into a mug, top it with hot water, and the syrup dissolves as the citron's perfume lifts off the surface. Because there is no leaf from the tea plant involved, it sits in the wide world of caffeine-free fruit infusions. If you want the botanical bracket, it is technically a tisane — the catch-all term for any brew that is not made from the tea plant — and a member of the broader herbal tea family. The Korean syllable "cha" simply means tea or infusion, so "yuja-cha" translates loosely as "citron tea."
Yuzu vs yuja: one citron, two names
This is the part worth pinning down, because the labels can be confusing. "Yuzu" and "yuja" are two names for the same fragrant East Asian citron. "Yuzu" is the Japanese reading; "yuja" is the Korean one. The fruit looks like a knobbly, uneven lemon, is intensely aromatic, and is prized far more for its zest and juice than for eating raw. When that citron is preserved in honey or sugar and stirred into hot water, Korean speakers call the drink yuja-cha, and it is the classic Korean honey-citron tea — a jar of it lives in a great many refrigerators through the winter. In English you will see the same product sold as "yuzu tea," "yuja tea," "yuja cha" or simply "citron tea," and they all point to the same golden spoonful. For where this drink sits alongside barley, corn and other brews, see our guide to Korean tea.
What yuzu tea tastes like
The flavor is the reason people keep a jar going. Yuzu tea is aromatic and sharp-sweet at once: the honey or sugar rounds it out, while the citron peel gives a fragrant, almost floral bitterness and a lemon-meets-mandarin brightness that ordinary lemon cannot quite match. A good cup smells of orchard and perfume before you even taste it. Because the peel goes into the jar, you get little strands of softened rind in the drink, and those are meant to be eaten — they carry much of the aroma. Sweetness varies with the brand and with how heavy-handed you are with the spoon, so it is easy to dial a cup up or down to taste.
How to make yuzu tea at home
Making it could not be much simpler, which is a large part of its charm. The standard approach is:
- Spoon roughly one to two teaspoons of yuja or yuzu marmalade into a cup or mug.
- Top it with hot — not furiously boiling — water, around 80 to 90C, so the honey notes are not scorched.
- Stir well until the syrup melts into the water and the peel loosens.
- Sip, and eat the softened citron strands as you go.
From there it is endlessly adaptable. Over ice with a splash of cold water it becomes a bright, cordial-like iced drink for warm afternoons. A spoonful stirred into an actual brewed cup — black or green — turns it into a fragrant citrus tea instead. Some people add a little extra honey, a slice of fresh lemon or a thumb of ginger for a sharper edge; if that appeals, our take on a honey, citrus and mint tea covers similar warm-and-bright territory.
Making the citron preserve yourself
Most people buy the preserve ready-made in a jar, and there is nothing wrong with that — it keeps for a long time in the refrigerator. If you would rather make it, the idea is straightforward and forgiving. Wash and dry the citron well, slice it very thinly with the peel on and the seeds removed, and layer the slices with roughly their own weight in sugar or honey in a clean jar. Let it rest, refrigerated, for a day or several so the sugar draws out the juice and the whole thing turns syrupy. Exact ratios and resting times vary from recipe to recipe, so treat this as a sketch rather than a strict formula — you are simply coaxing a marmalade out of citron and sweetener.
When yuzu tea is enjoyed
Yuzu tea is, above all, a cold-weather comfort drink. It comes into its own in autumn and winter, when a hot, fragrant, faintly tart cup feels especially good, and it is a common thing to offer a guest who has just come in from the cold. Many people describe it as soothing and reach for it when they want something warm and citrusy rather than caffeinated. The iced version keeps it in rotation through the warmer months as well. None of this is medicine — it is simply a pleasant, aromatic drink — so enjoy it as the seasonal treat it is.
Is yuzu tea caffeine-free?
Yes. Because yuzu tea is made from citron preserve and hot water, with no leaves from the tea plant, it is naturally caffeine-free. That makes it an easy choice in the evening or for anyone cutting back on caffeine, in the same bracket as most fruit and herbal infusions. If you do stir the preserve into a cup of brewed black or green tea, that base tea brings its own caffeine along with it, so the caffeine-free label only holds for the plain hot-water version.

For all the two-name confusion, yuzu tea is one of the simplest good things you can keep in a kitchen: a jar of golden citron, a kettle and a spoon. Whether you call it yuja-cha, citron tea or yuzu tea, it turns a few seconds of stirring into a fragrant, sunny cup — proof that some of the most comforting drinks in the world never meet a tea leaf at all.
