Ember & Oak

Bristol · est. 2019 · bottling batch No. 214

Salt, oak, and fourteen months of doing nothing.

Ember & Oak is two people in a railway arch off Kingsland Road. We brine British-grown chillies with nothing but salt, leave them in oak somewhere between eight and fourteen months, and bottle what comes out — unpasteurised, three hundred bottles at a time, numbered by hand.

  • 8–14 months in oak
  • No vinegar added
  • 300 bottles a batch
  • UK delivery £3.95, free over £40

Wild-fermented No vinegar added British-grown chillies Unpasteurised Keep refrigerated

The range

Four ferments, one arch, one barrel room.

Every sauce starts as the same three things: chillies, salt and time. What changes is the chilli, what we add to it, and how long we are prepared to wait.

House Ember

The one we put on everything.

The method

How it works, in four moves.

This is the whole recipe. There is no fifth move, and there is nothing in the bottles that is not on this list.

  1. Salt, not starter

    Chillies, salt, and a 2.5% brine by weight. We do not add a cultured starter or a vinegar kick because the skins already carry everything the ferment needs. The salt decides which microbes get to stay.

  2. Oak, not plastic

    The mash goes into oak in an unheated arch under the railway. Somewhere between eight and fourteen months later the pH has fallen to about 3.4 on its own, and the flavour has gone somewhere we could not have taken it on purpose.

  3. Blend, then stop

    We blend with the brine the chillies fermented in, taste it, and stop. No thickener, no sugar, no vinegar top-up and no pasteurisation — which is why every bottle tells you to keep it in the fridge.

  4. Number, then send

    Three hundred bottles a batch, filled and labelled by hand, each stamped with its batch number and bottling date. When a batch is gone, it is gone until the next one is ready.

If we wanted to make this faster, we would have to make it worse. We have done the maths on that twice a year since 2019 and it has not changed.

Heat

Where each bottle lands.

Measured by HPLC at a lab in Cardiff, on the bottled sauce — not estimated from a chilli chart, and not decided by somebody eating a spoonful on camera.

Figures are the midpoint of each batch's range. Fermentation moves the number around a little from barrel to barrel; the label always carries the range for the batch in your hand.

Every dispatch goes out in a moulded pulp carton with paper tape — no plastic, no polystyrene, no shrink wrap on the caps. Payments are taken the day before dispatch, and you can stop them from the same email.

Stockists

About forty shops, six of them well stocked.

We deliver by van to the south-west and by courier everywhere else. These six carry the full range for most of the year; the other thirty-odd carry whatever survived the last dispatch.

  • Bramble & Rye

    Gloucester Road, Bristol

    Full range, including the Barrel Reaper allocation.

  • Kirkgate Larder

    Kirkgate Market, Leeds

    Full range. Ask at the counter — it is kept behind the till.

    House Ember and Green Riot all year; Quince & Ash from October.

  • Owen Street Grocers

    Owen Street, Manchester

    Full range, plus whatever barrel experiment is current.

  • Harbour Stores

    Chapel Street, Penzance

Run a shop or a kitchen?

We wholesale by the twelve-bottle case, with no minimum order after the first, and we will swap out anything that is not moving. Trade sheet, case prices and shelf-life notes.

What we do not do

Four things we will not sell you.

There is no customer review section on this page, because we would rather tell you the awkward parts ourselves.

  • We do not pasteurise. Every bottle is live. Once it is open it lives in the fridge, and it will keep fermenting gently if you leave it out.
  • We do not bulk it out with vinegar. If a barrel tastes thin, it goes into a smaller run or into a cooking sauce we sell at the arch — it does not get stretched with acid to fill bottles.
  • We do not ship in plastic. Pulp cartons, paper tape, aluminium caps. The only plastic in the parcel is the safety seal on the bottle, and we are still looking for a replacement for that.
  • We do not have a marketing department. There are two of us. One of us is bottling today, and the other one is answering your email.
Barrel Reaper is 100 ml rather than 150 because fourteen months in a first-fill barrel costs roughly twice what the same time in a neutral one costs. We would rather sell you less of it than make it out of a flavour concentrate and call it the same thing.
