01  The clock

Since 1540 the palace clock has shown the time of high water at London Bridge. The court read it to catch the barge.

Ours are smaller. Twenty-eight seconds on a shot. Three minutes forty on a filter. Ninety-three degrees in the kettle.

High Water is a coffee counter in a brick store on the Barge Walk, between the palace wall and the river. Twenty-two seats, one grinder per coffee, a kitchen that bakes twice a day. We open at half past seven and lock the door at five, and in between the clocks are the only thing we are strict about.

The coffee is bought on sample, roasted in Kingston and rested before it is served. The water is the Thames, via the mains and a filter, which the clock in Clock Court would appreciate.

02  Green to cup

Six steps, each with a number attached.

01
Roasted beans spilling from a brass scoop onto slate.

Green

Lots of twenty to sixty bags, bought on sample from three importers we have worked with for years. Every lot is cupped blind against last year's before we commit, and we pass on more than we buy.

Freshly roasted beans being raked in the cooling tray of a drum roaster.

Roast

Small batches on a 12 kg drum in Kingston, a mile downriver. Eight to nine minutes to first crack, dropped a shade lighter than most London roasters so the origin is still there in the cup.

Then nothing. Seven days before it goes on espresso, three before filter. The gas has to leave.

Rest

The bag carries a roast date, not a best-before. We think the window is day seven to day twenty-one and we will tell you where the coffee you are drinking sits in it.

04
A gooseneck kettle pouring over a V60 on a scale.

Grind and water

Ground to order, single dosed, weighed to a tenth of a gram. The mains at Hampton Court runs hard, so we filter to about 80 parts per million and remineralise for espresso. The old clock cared when the water was high; we care what is in it.

A green-glazed stoneware cup of espresso with cardamom pods on the saucer.

Extract

Espresso at one to two in twenty-six to thirty seconds at 93 °C. Filter at one to sixteen, four pours, three minutes forty. The cardamom espresso is a double pulled over three cracked pods, no sugar, and it is the one people cross the bridge for.

We taste it before you do. Every batch, every morning, and a second time after lunch.

Cup

If a shot drifts outside the window we pull it again and the first one goes down the sink, not into a latte. That is the whole quality system, and it fits on a card by the grinder.

Grind

Whole bean unless you ask. We grind for espresso, filter or cafetière, and we would rather you let us know your brewer.

Subscriptions

Not yet. Every bag we post is roasted that week and we are not big enough to promise that monthly.
