Infusers & strainers

Hold leaf inside the water while it steeps and take it out again cleanly, which is what makes a steep time enforceable rather than aspirational.

Leaf needs two things that a small metal ball cannot give it: room to unfurl to its full size, and water circulating through the whole bed rather than around the outside of a compacted lump. It is the same argument as a coffee basket — free volume around the bed and open area in the mesh decide whether extraction is even. The second, and more operationally important, function is removal. Tea does not stop extracting when the timer sounds; it stops when the leaf leaves the water. An infuser the barista can lift out in one movement makes the steep time a real control. A pot with no removable basket, a bag left in the cup, or leaf loose in the water makes the steep time a suggestion, and the drink continues to change all the way to the table. Mesh fineness is the third variable and it follows the leaf grade: whole leaf needs open mesh so water can move, broken and CTC grades need finer mesh or they end up in the cup.

  • Choose from the LEAF first, then from the service format. Whole-leaf grades need volume and open mesh or they will not open; broken and CTC grades need fine mesh or they will pass into the cup. Buying one infuser for a menu that carries both is how a bar ends up serving cloudy green tea and weak black tea from the same equipment.
  • Insist on removability, and treat anything that cannot be lifted out in one movement as a fault. This is the point of the whole item. A steep time you cannot end is not a specification, and no amount of timer discipline fixes a pot the leaf cannot leave.
  • Count the wash-up before you count the unit price. An infuser per cup is a labour and a sink-space decision multiplied by every tea you sell, and it is routinely left out of the comparison because it does not appear on the invoice. On a high-volume bar this is often the argument that decides between a basket and a filter bag.
  • For pot service, solve what happens at the table. The basket comes out at the guest's table, and if there is nowhere to put it, it goes back in the pot and the last cup of a three-cup pot is the worst one. An inverting lid or a small saucer is a trivial cost that protects the whole drink.
  • Standardise on as few infuser types as the menu allows. Every extra type is another wash-up size, another storage slot and another chance for the wrong one to be picked in a rush — the same argument that keeps a bar to one basket size on the espresso side.
  • Buy stainless over plastic where the mesh will meet near-boiling water many times a day, and check that the mesh is fixed rather than glued. A mesh that lifts from its frame traps leaf in the seam, and that seam cannot be cleaned properly once it does.
  • Size the infuser to the vessel it will actually be used in, not to the biggest one you own. An infuser that does not reach the water in a tall pot brews the top third of the pot and nothing else, and the fault reads as a weak tea rather than as an equipment mismatch.
  • Decide cloth versus paper on which discipline your team already keeps. Cloth socks are cheaper and greener and require washing without detergent, full drying and scheduled replacement — a routine that fails quietly. Paper costs per serving and never fails quietly. Neither answer is wrong; choosing the one that matches the team you have is the decision.

Immediately at the tea station, with the leaf, the dosing spoon or scale, the timer and a drip receptacle in the same reach. The whole sequence — dose, pour, start the timer, lift out — should be one arc without a step taken, because every step taken is a second added to a steep that was specified to the minute.

  • Buying ball infusers because they are cheap and familiar, then concluding that loose leaf is not worth it.
  • Serving a pot with a basket the guest has nowhere to put down.
  • Running one mesh grade across a menu that carries both whole leaf and CTC.
  • Leaving the infuser in the cup and calling the timer a control.
  • Choosing an infuser that does not reach the water line in the tallest pot on the menu.
  • Costing infusers by unit price with no line for wash-up labour or sink space.
  • Washing cloth filters with detergent, or storing any infuser damp and stacked.
  • Negligible on the counter and material in the wash-up and the drying rack. Plan the storage and the drying, not the counter space — wet infusers stacked in a tub are how a tea station starts smelling.
  • Enough room beside the brewing vessel to set a hot, dripping infuser down on something that is meant to receive it.
  • Deep basket infuser
  • A wide, deep mesh basket that sits in the cup or pot and holds the leaf in a loose bed.
  • The best general answer for loose leaf: enough volume for the leaf to open, enough mesh area for water to move, and one movement to remove. It costs more per unit and it is one more item through the wash-up for every drink — a real labour line on a bar selling tea by the cup.
  • Ball or spring-clamp infuser
  • A small perforated sphere or clamp that encloses a compressed pinch of leaf.
  • Cheap, familiar, and the reason a lot of loose-leaf tea tastes worse than the bag it replaced. The leaf cannot expand and the water cannot circulate, so the outside over-extracts while the inside stays dry. Acceptable only for fine, broken grades that need no room, and even then it is a compromise.
  • Integrated removable pot basket
  • A full-width basket built into a service teapot, lifted out at the end of the steep.
  • The right architecture for pot service: maximum bed volume, and removal is part of the service ritual rather than an extra task. Its weakness is what happens after the guest gets the pot — if the basket is lifted at the table and there is nowhere to put it, it goes back in, and the last cup is bitter. Specify a lid that inverts to hold the basket, or send a saucer with it.
  • Cloth sock or paper filter bag
  • A disposable paper pouch, or a reusable cloth sock, filled with the dose and steeped.
  • Paper removes the wash-up entirely and gives a clean cup, at a per-serving cost and a waste line, and it holds back some aroma. Cloth is cheaper per serving and must be washed without detergent, dried fully and replaced on a cycle, or it holds the last tea and stains the next. Cloth is a discipline commitment; paper is a cost commitment. Choose the one your operation actually keeps.
  • Pour-through mesh strainer
  • A handheld strainer held over the cup while tea is decanted from a pot brewed with loose leaf.
  • The traditional answer and still the best one for a concentrate pot or any pot brewed without a basket, because the leaf never limits the brew. It moves the control to decanting: the tea must leave the pot on time, and whatever stays behind keeps extracting. It also puts one more hot, dripping object in the operator's hand mid-service.
  • Loose-leaf tea tastes weaker than the bagged tea it replaced, at the same dose.
  • The leaf is packed into an infuser too small to let it expand, so most of the bed never meets moving water.
  • Drink quality and money — you are paying for whole-leaf tea and extracting a fraction of it, then often increasing the dose to compensate.
  • The first cup from a pot is right and the last is bitter.
  • The leaf never left the water — no removable basket, or the basket was lifted at the table and put straight back because there was nowhere to set it.
  • Drink quality on the part of the drink the guest lingers over, and it reads as bad tea rather than as a missing saucer.
  • Sediment or fine particles in the cup on the broken and CTC grades.
  • Mesh chosen for whole leaf being used for a finer grade.
  • Presentation and mouthfeel, and a complaint that is easy to dismiss as normal until a guest sends it back.
  • A cloth sock or a reused infuser carries the previous tea into the next one.
  • Washed with detergent, dried incompletely, or reused across tea types without a rotation.
  • Drink quality on the more delicate tea of the pair — the green always loses to the residue of the black — and it is a hygiene issue as soon as anything is stored damp.
