What are pyramid tea bags?

A pyramid tea bag is exactly what the name suggests: a tetrahedron, stitched or sealed from a fine mesh instead of paper, holding roughly two to three grams of leaf. It went on sale in the UK in the late 1990s and is now the format most cafés reach for when they want tea that stands up next to the coffee they are serving.

The shape is not decoration. A flat paper bag is a sealed envelope pressed almost shut, and the leaf inside sits in a compacted layer. Water has to work its way through that layer rather than move around it. A pyramid gives the leaf a three-dimensional chamber to move in, so hot water circulates on all sides and the extraction happens evenly.

How they are made

Pyramids are formed on a machine that folds a continuous tube of mesh, doses the leaf, then seals the tube at right angles to the previous seal. Turning each seal ninety degrees is what produces the four-sided shape. The mesh itself is woven finely enough to hold tea dust back but open enough to let colour and flavour out quickly, which is why a pyramid looks slow for the first ten seconds and then catches up.

Most pyramids carry no tag and no staple. The bag is sealed by heat or ultrasound, so there is no metal to pick out and nothing to separate before composting.

What goes inside

The bigger difference is the grade of tea, not the geometry. Standard paper bags are filled with fanning's and dust, the small particles left after larger leaf is graded out. They brew fast and strong, and they brew flat. Because a pyramid has room inside it, it can be filled with larger broken leaf and whole leaf, and with visible botanicals: peppermint leaf, whole rosebuds, chunks of ginger and lemongrass.

That is what a customer notices across the counter. Larger leaf gives up its flavour more gradually and more completely, so the cup has body without the astringency that comes from over-extracted dust. It also holds up to a splash of milk without collapsing into tannin.

The mesh question

Early pyramids were made from nylon or PET, and plenty still are. That is the fair criticism of the format: a bag that looks like silk is often plastic, it will not break down in a food waste bin, and it is heated to just under boiling in a cup someone is about to drink from.

The mesh worth buying is made from plant starch instead. Novus pyramids use a plastic-free mesh spun from non-GM cornstarch, sealed without staples or glue, and certified industrially compostable. Bag, leaf and carton all go in the food waste. It is also worth checking the outer packaging, since a compostable bag inside a plastic-laminated envelope has not solved much.

If you serve tea in a venue with a food waste stream, this is the detail to ask your supplier about first. It is the one claim on the box that changes what happens to the bag after the cup is cleared.

What we stock

We supply Novus across Hertfordshire, Essex, Cambridgeshire and London. It is a British family tea business, Rainforest Alliance certified, and the pyramid range covers a full tea list without needing a second supplier.

Is it worth the difference?

A pyramid costs more per cup than a paper bag, and for a self-serve kitchen tin that may not matter to anyone. Where it earns its keep is anywhere the cup is being sold or served to a guest. Tea is usually the highest-margin item on a café menu and the one most often treated as an afterthought. A visible whole-leaf pyramid in a pot supports the price on the board, and it stops the person who does not drink coffee from feeling like they drew the short straw.

If you are unsure which teas will sell in your venue, start with six lines: a strong English breakfast blend, a decaf, Earl Grey, green, mint and camomile. That covers almost every order, and you can build out from there once you see what moves.
