The Tea Towel: The Square of Cloth That Keeps a Tea Table Honest

Autumn rain in Shanghai falls sideways, the kind that gets under the awnings of the old town and soaks your shoes from the ankle up. I ducked into a teahouse off Fangbang Road to wait it out, and the woman who owned the place did not look at me. She was folding a piece of dark blue cloth. A third over, then another third, until the square had become a neat brick the size of a pack of cards, and she set it beside the kettle with the folded edge facing outward. Then she wiped the bottom of the cup she had just filled, put it in front of me, and said, "Now you can drink it." The tea was a shou mei, decent, nothing to write home about. What I remember from that afternoon is the cloth. 茶巾, chájīn, the tea towel. Not a rag. She must have folded it back into that brick a dozen times while I sat there, and not once did she leave it crumpled on the table.

It is the cheapest object in the gongfu kit and the only one whose entire job is manners. Every other tool on the table makes tea taste better. The towel is there so the table stays dry and nobody has to think about it.

What the towel actually does

Three jobs, in order of how often you do them. First, the bottom of the cup. A gaiwan pours with a certain amount of slop, and the base of a filled tasting cup always carries a drop or two. Hand that cup to a guest unwiped and the tea ends up on their fingers, then on the table, then on the tray, and the small ritual of passing tea turns into a small mess. Wipe the base, every pour. Second, the table itself. Water around the gaiwan, drips from the fairness pitcher, a leaf that jumped. Third, the spout of the pot, which weeps while it sits and leaves a ring on the wood.

The material matters more than people expect. You want cotton, linen, or a blend of the two, in a dark plain weave, roughly twenty-five to thirty centimeters square. What you do not want is terry cloth, the looped towel from your bathroom. Those loops shed. Run one over a wet porcelain rim and you will find lint floating in the next infusion, and lint is not a flavour. Terry also holds water in its pile and stays damp for hours, which is how a towel starts to smell like the bottom of a teapot. Linen dries fast, which is the real reason it shows up in tea houses: you use the same cloth forty times in an afternoon and it has to be dry again in ten minutes. You can feel the difference before you use it. A good tea towel is a little stiff when it comes off the shelf, almost papery, and goes soft the instant water touches it. If it feels limp and plush dry, it will push water around the table instead of taking it up.

Dark colour is not decoration either. Tea stains. A white towel looks beautiful for about a week, then it looks like a map of everything you have spilled, and no wash gets the tannin back out. Indigo, charcoal, brown: these hide the work. In the nicer tea rooms the towel is hand-dyed and matched to the tray, which is a pleasure of its own. The function comes first.

Two cloths, one line from 780 AD

None of this is a modern affectation. Lu Yu, in the Classic of Tea, devotes one entry of his catalogue of twenty-four tea vessels to the cloth:

巾，以絁布为之，长二尺，作二枚，互用之，以洁诸器。

The cloth is made of coarse silk, two chi long. Make two of them and use them alternately, to clean the vessels.

Two chi in Tang measure is roughly sixty centimeters, twice the size of a modern tea towel, because Lu Yu's cloth wiped bowls, sieves and the tea grinder, not a cup the size of a walnut. The instruction that survived is the interesting one: 作二枚，互用之. Make two, alternate them. One wet to lift the residue, one dry to finish. Every competent tea table I have sat at still does this, whether the person has read Lu Yu or not.

The rule that surprises visitors is about what the towel is not for. It does not touch your hands or your face. It belongs to the table and the vessels. Wipe your palms on it in a serious tea room and you will get a pause, then a polite change of subject, and somebody will quietly hand you a paper napkin. The towel is a shared object; your hands are yours.

The Japanese borrowed the word and changed the object. In chanoyu, a 茶巾 (chakin) is a small bleached linen cloth used to wipe the tea bowl before and after whisking, and it never goes near the table. Same two characters, different job, different etiquette. Worth knowing before you tell a Japanese host that you keep one for spills.

The rules that keep it from turning

One: buy two, keep them plain. Plain cotton or linen, dark, no print, no terry, no microfibre. Two of them, because one is always drying. This is one of the few pieces of tea kit where spending more buys you almost nothing; a good kitchen supply shop sells the right cloth for the price of a coffee. What you are paying for is the weave, not the label.

Two: fold it, do not ball it up. Fold in thirds, twice. Wet corner for cup bases and spills, dry corner for polishing the rim and drying the tray. Re-fold when the wet side gets too wet, and put it back in the same place on the table. A towel with a home is a towel you can find with your hand while you are looking at the guest.

Three: hot wash, no softener, dry flat. Fabric softener coats the fibres with a film that kills absorbency, so a softened towel smears water across the tray. Boil a new one once to strip the factory sizing, then wash hot with nothing fancy and hang it flat. Rinse it at the end of every session. A towel left damp overnight grows a smell that washing never entirely removes, and then you are drinking yesterday out of a clean cup.

Amazon is not much help on this one. Search for a tea towel and you get bar mops by the dozen and printed kitchen sets with lemons on them. Buy the plain square locally and spend the money on the surface it protects. A hardwood gongfu tray with a water box under the slats is what makes the towel's job possible, and if you want the version with a drainage lip, this seventeen-inch wooden tea tray is the one I would start with. Set the folded cloth at your right hand, fill the kettle, and the table starts to behave like a table.
