Lao Cha Tou: The "Old Tea Head" Nuggets of Shou Pu-erh

Lao Cha Tou (老茶头, "old tea heads") are hard little nuggets of shou pu-erh that form when leaves stick together during the wet-pile fermentation. They make up only about 15% of a pile and are sifted out and sold on their own. In the cup they're sweet, smooth and creamy, with less of the earthiness that puts some people off shou. Brew them like shou, with boiling water, and give them a rinse or two to loosen up.

They look like gravel, or something you'd sweep off a factory floor. That's part of the charm. Few teas look less promising in the bag and taste better in the cup.

Why the nuggets form#

Shou is made by wo dui (渥堆), wet piling. Sun-dried maocha is heaped up, dampened, covered with cloth and turned roughly once a day while microorganisms, including Aspergillus moulds, do their work. A pile needs at least a tonne of leaf to hold its heat, and three to four tonnes is better. The method dates from the early 1970s, developed at the Kunming and Menghai factories.

Inside that warm, damp heap, some leaves glue themselves together into firm lumps. They don't break apart when the pile is turned, so at the end of fermentation they're picked out by hand or sieve. What's left becomes ordinary shou; the lumps become Lao Cha Tou.

Sweeter and creamier than ordinary shou#

Good Lao Cha Tou is round and mellow, with a dark-sugar sweetness and a touch of wood. The texture is the main draw: thick and silky, more like a dark syrup than a tea. Bitterness is low and the earthy, "cellar" side of shou is quieter.

Because the leaf is packed so tightly, it opens slowly. The first steeps can be lighter than you expect, and the tea often hits its stride a few infusions in. Patience pays here more than with most shou.

Where it sits among shou grades#

Shou grade	What it is	In the cup
Gong Ting (宫廷)	Fine leaf and small buds	The liveliest shou, and the easiest to over-brew
Jin Ya / Jin Hao	Lots of buds with golden down	Delicate, sweet, smooth
Blends	Mixed grades, most of the market	Anything from rough to excellent
Lao Cha Tou (老茶头)	Lumps that stuck together in the pile	Sweet, creamy, slow to open

Like most shou, Lao Cha Tou is usually made from everyday leaf rather than famous mountains or old trees. Its appeal comes from the process, not from a prestigious address. You'll find it loose and, less often, pressed into bricks or small cakes.

Brewing the nuggets#

Method	Leaf	Water	Rinse	Time
Gongfu	3–5 g per 100 ml	Boiling	1–2	15–30 s, +5 s each; 5–8 steeps
Mug or teapot	A few nuggets per 300–400 ml	Boiling	1 quick rinse	3–4 min, then re-steep

These are the shou numbers from the gongfu brewing chart. Two adjustments help with the nuggets. Rinse them properly, since a hard lump needs hot water to start opening. Then, when the early steeps seem thin, add time rather than more leaf. A gaiwan works well, and a clay pot suits the thick texture.

No knife is needed. Unlike a pressed cake, loose nuggets simply go into the pot, and they're happy with water straight off the boil. The full routine for shou is in how to brew pu-erh.

Picking good nuggets#

After the rinse, Lao Cha Tou should smell clean, sweet and earthy. A sharp, fishy "pile" smell means the tea is too fresh from fermentation and needs time to air. Musty or sour is a fault, not character.

Look for nuggets of fairly even size and colour, without dust or stems. The spent leaf should unfold into recognisable pieces of leaf rather than mush.

Store them like any shou: in a closed box or tin, away from light and strong smells, with a little air. They're forgiving, and they mellow further with a few years of rest. The longer version is in how to store pu-erh, and the wider picture in the pu-erh guide.

If shou has ever struck you as too earthy, this is the one to try next. It's the same tea with the rough edges rounded off.
