Right now there are crates in the back of a truck driving from a pepper field to our door, and the whole rest of the year depends on what happens in the next few hours.
That sounds dramatic. It isn't. We ferment a full year of product during one harvest window, which means every crate that comes through the door in August and September either becomes sauce or it doesn't, and there is no second attempt in February. Peppers do not wait for a convenient schedule. They ripen when they ripen, they get picked, and from that moment they are on a clock.
The clock is tighter at the front end than most people picture, and looser at the back.
How long can a picked pepper wait before it goes into brine?
Our ideal is 48 hours from picked to submerged. The rule we hold to is stricter at the start and more flexible after: peppers have to reach the walk-in cooler the same day they come off the plant. Once they are cold, how long they hold depends on the pepper.
Jalapeños are forgiving. Thick walls, sturdy skin, and they will sit in the cooler and stay firm well past the point where other varieties have started to give. Fresnos and habaneros are a different conversation. Thinner walls, and they soften sooner, which means a habanero load and a jalapeño load that arrive on the same afternoon are not on the same schedule at all. We plan the week around that.
The same-day part is the piece that doesn't flex. A pepper left at ambient temperature for a day has started down a road you cannot walk back. A pepper in a cooler within hours has been paused. Everything after that is a question of how well you use the pause.
We work to get every batch processed as fast as we can regardless, because the shortest version of that timeline is always the best one. But we would rather set up a clean ferment on day four than rush a sloppy one on day one.
This applies to everything we make. The peppers headed for a 21-day lacto brine and the peppers headed for an eight-month koji build run the same clock. Different ferments, same standard at the door.
What goes wrong when a pepper sits
Two things, and only one of them is about flavor.
The first is softening. Cell walls lose structure as the fruit keeps respiring and losing moisture. A firm pepper slices clean and holds its shape in brine. A soft one goes mushy, releases unevenly, and gives you a ferment with a texture we would not put our name on.
The second is the one that drives the clock: the risk of mold and cross contamination climbs. A walk-in during harvest is a busy place. Crates come in, crates go out, and every day a batch sits in that traffic is another day of exposure to whatever else is in the room. Surface microbes are not a problem in themselves. Fermentation is a controlled competition, and we want Lactobacillus to win it. What we don't want is to hand a head start to something else before the brine ever gets involved.
That is the honest version of "fresh." Structure and microbial load, both degrading on a schedule you can measure. It has very little to do with a pepper picked at dawn.
If you have read about reading a ferment for kahm yeast and mold, this is the upstream half of the same subject. Most of what goes wrong in a crock was decided before the crock was filled.
Why we drive out and pick the peppers up ourselves
We could have the peppers delivered. We don't, and the reason has nothing to do with logistics.
Driving out to the farm is the only time all week we are standing in the field with the people who grew what we are about to ferment. We get crop conditions straight from the source. We hear what the weather did to the block on the north side. We find out what we could be doing differently to make their work easier, which is a conversation that never happens over a delivery manifest.
Our growers are within a short drive of our kitchen, here in the Red River Valley, and they have asked us not to name them, which we respect completely. What we will say is that they are very good at this.
Sorting on arrival costs us somewhere between five and twenty percent of a load, and where a given load lands in that range says more about the pepper than about the farm. The sturdy varieties come in near the bottom of it. The thin-walled ones come in higher no matter who grew them or how carefully they were handled, because that is what those peppers are. A single flat number across every variety would be a tidier thing to publish. It would also be wrong.
We also don't tell them when to pick. They are the experts on ripeness in their own rows, and we trust that judgment the way we would want them to trust ours on a pH curve. More on what the ground itself contributes in why where a pepper grows ends up in the bottle.
What ferment day looks like
The peppers get washed and stemmed the day we set up the ferment, not before. Washing and then holding wet produce invites exactly the problems we spent the cooler run avoiding.
Then, in order:
- Sort. Anything soft or damaged comes out. See the next section for how that call gets made.
- Wash and stem.
- Slice. We slice the chilis before they go in. Not whole, not a mash. Slicing opens enough surface area for the brine to penetrate and for the pH to drop evenly through the batch, without pulverizing the fruit into a slurry that ferments in a completely different way.
- Brine and weight. Sliced chilis go into a salt brine and get held under with heavy food-safe glazed ceramic plates. Everything stays submerged. Anything that floats is a problem waiting to happen.
- Into the room. Our fermentation space is temperature controlled and runs at 72 to 74°F. Warmer would ferment faster. Warmer is also much harder to control, and it costs you complexity and risks off flavors. We would rather wait and get the ferment we designed.
From there the lacto batches run a minimum of 21 days, cold processed the whole way through, and finish at or below pH 3.5. The #KojiHachi peppers go a different direction, onto an eight-month minimum koji build where Aspergillus oryzae enzymes spend months converting the pepper into free glutamates. Those builds start inside this same window, on peppers from this same season. A #KojiHachi ferment set up in September will not be a bottle until the following summer at the earliest, and the reserve batches run two to four years. Same crates at the door. Wildly different destinations.
The rule that settles every close call
There is a line from the movie Ronin that we have borrowed as an operating standard: if there is ever any doubt, there is no doubt.
Applied to produce, it means that if we are standing over a crate arguing about whether something is still good, the argument is already over. It doesn't go in. There is no version of that debate where the answer is "probably fine." Probably fine is how you lose a batch, and losing a batch during harvest means losing product you cannot make again until next year.
It sounds expensive. It is much cheaper than the alternative.
Why the entire year gets made in one season
Harvest normally opens in mid July and runs until the first hard frost, usually sometime in October. That is the window. Everything we bottle and ship over the following twelve months has to be set up inside it.
Which means harvest is not a season for us so much as a sprint. Eighty hour weeks, back to back, for as long as the peppers keep coming. Pick up, sort, wash, stem, slice, brine, weight, label, log, repeat, and then do it again tomorrow because another field came ready overnight.
We are two people. There is no shift we can hand this to.
That is what "small batch" costs, and it is why we say you can't cheat time. The 21 days and the eight months get all the attention, and they should. The part that gets less of it is that the raw material for all of it has to be captured inside about ten or twelve weeks, once a year, or it simply doesn't exist.
This year the window is shorter
Drought pushed our harvest start later than normal. The forecast is now raising the possibility of an early frost.
Late start, potentially early finish. That is a compressed window on both ends, and it is the kind of year where the discipline matters more, not less. When there is less time, the temptation is to relax the standard at the door and let a marginal crate through because you need the volume. That is precisely when you can't.
We will make what the season gives us. If a batch runs short this year, it runs short. What won't happen is a bottle going out that we hurried.
What this means if you ferment at home
Home fermentation advice tends to start at the jar. The hours before the jar decide more than they get credit for.
Three habits from a commercial harvest that transfer straight to a kitchen counter:
- Get your peppers cold the day you get them. A farmers market haul on Saturday morning goes in the fridge Saturday morning, not Sunday night. That single habit buys you most of the shelf life you're going to get.
- Wash on ferment day, not before. Wet produce in storage is a worse problem than dusty produce in storage.
- Sort ruthlessly, then sort again. One soft pepper does not ruin a jar by magic. It does raise the microbial load in a system where you are trying to give one organism an advantage. When in doubt, leave it out.
Frequently asked questions
How fresh are the peppers in Off the Deck hot sauce?
Every pepper reaches our walk-in cooler the same day it is picked, and our target is 48 hours from field to brine. How long a cold-held load stays usable after that depends on the variety: jalapeños hold considerably longer than thinner-walled peppers like Fresnos and habaneros. We process every load as quickly as harvest volume allows.
Do you ferment year round?
No. We set up an entire year of production during the harvest window, which normally runs from mid July until the first hard frost. The ferments themselves then run on their own timelines, from 21 days for the lacto line to eight months and beyond for #KojiHachi.
Are the peppers whole, sliced, or a mash?
Sliced. Slicing gives the brine enough surface area to penetrate and drop the pH evenly across the batch, without breaking the fruit down into a mash.
Where are the peppers grown?
On a farm within about thirty miles of our kitchen, here in the Red River Valley. Our growers have asked to stay unnamed and we honor that.
Does a shorter harvest mean less sauce?
Possibly. A compressed season means fewer batches, and we would rather run short on a sauce than lower the standard on what goes into it.
Somewhere in the next few weeks, the last crate of the year is going to come through our door and we won't know it's the last one until the frost tells us. Everything you'll taste from us for the next twelve months is being decided right now, in a cooler, in a sprint, in a season running shorter than we'd like.
If you want to taste what came out of it, the lacto-fermented line is where a harvest shows up fastest. The #KojiHachi bottles on the shelf today came out of a harvest you'd have to go back a few years to find.
You can't cheat time. We never tried.
