Ember & Oak is a four-person kitchen on Roberts Street in Asheville, North Carolina. Every sauce starts the same way: whole chiles packed into a 3.5% fine sea salt brine and left in a ceramic crock for six to seventeen weeks. Nothing is pasteurized, nothing is thickened with xanthan, and nobody tastes a batch until the pH says it is done.
Batch 41 — 612 bottles, bottled 14 September 2026. Batch 42 comes out of the crock the first week of November.
Four recipes, all of them in rotation. The figures below are the ones we write on the crock lid in marker, listed in the order the sauces come out of the fermentation room.
Days in the crock, Batch 41
The one that goes on eggs. Bright and garlicky and barely warm — closer to a ripe tomato that got a sunburn than to anything you would call hot. It is also the bottle we hand to people who tell us they do not like hot sauce.
Carrot and habanero ferment into something that tastes closer to a Caribbean curry than to a hot sauce. Ten weeks in the crock, then lime leaf at the blend. This is the one we cook with — rice, grilled fish, anything cold that needs waking up.
Sweet for about a second and a half, then a long dry burn that arrives at the back of your throat instead of the front of your tongue. Our best seller, and the reason we buy aji amarillo by the case every August.
Reaper and black garlic, seventeen weeks in the crock and then four weeks resting on a toasted oak stave from a sawmill over in Brevard. Smoke and molasses first, Reaper second, and it stays with you. A quarter-teaspoon is a serving, which is what makes it worth twelve dollars a bottle.
Four hundred bottles a year. This is the one that runs out.
We buy chiles at the end of their season, when they are cheapest and sweetest, and pack them in whole. A 3.5% brine of fine sea salt and Asheville tap water — no starter culture, no vinegar, no heat. The crock sits in the back room between 62 and 68°F, and the salt-tolerant bacteria already living on the skins do the rest.
Lacto-fermentation turns the sugar in a chile into lactic acid. That is where the sourness comes from, and it is why a fermented sauce tastes rounder than one built on distilled vinegar — and why ours holds for two years on a shelf without being pasteurized. We pull a batch when the pH lands between 3.2 and 3.6 and the brine has stopped tasting of salt and started tasting of the fruit we were hoping for.
Then it is blended with a little of its own brine and bottled into 5 fl oz glass. A batch runs 300 to 700 bottles. When one is gone it is gone until that chile comes back in season, which is why the shelf is never quite the same two months running.
We are not in the big chains and we are not on the delivery apps. These eight shops order straight from the kitchen, keep us on a real shelf rather than in a warehouse, and will nearly always let you taste before you buy.
Run a shop that would like us on the shelf? Email wholesale@emberandoak.com and we will send a sample case of all four, freight covered.
