Where do I buy peppers by the case or the barrel?

Bulk peppers come from five kinds of sellers: local farms and produce auctions for fresh peppers in season, wholesale produce distributors for fresh peppers year-round, frozen-vegetable suppliers, pepper mash and puree makers, and dried chile importers and packers. Which one fits depends on whether you need fresh flavor, year-round supply or a consistent base. Commercial hot sauce is commonly built on fermented red pepper mash, which the trade ages in barrels from 2 weeks to 3 years [1]. Whoever you buy from, put a written specification in place and inspect every delivery. This page compares the sources, lists what to put in a specification, and gives an inspection checklist for fresh, frozen, mash and dried peppers.

Five places to buy, compared

The USDA's commercial specification for hot sauce names fermented red peppers, jalapeño peppers, chipotle peppers, habanero peppers and chili pepper paste as pepper ingredients [2]. In other words, a commercial sauce may never touch a fresh pepper at the plant.

Choosing by stage

• Testing recipes at home. Buy fresh at a grocery or farm stand, a few pounds at a time. At this stage you are learning the pepper, and price hardly matters.
• Farmers market seller, a few batches a season. A grower or the auction at peak season, with the surplus frozen or salted into mash. See storing peppers until you make sauce.
• Steady small brand. A distributor or frozen supplier for the base pepper, or a mash supplier, with a written specification. Keep a second approved source in case the first runs short.
• Copacked brand. Your copacker may buy peppers for you. Your specification still governs what goes in.

What to put in a specification

A specification is a one-page agreement on what you are buying. It protects you, it makes inspection objective, and a process authority or copacker may ask for it. Ask the supplier for theirs and adjust it to yours.

For fresh and frozen peppers

1. Variety, by name, and species if it matters (for example habanero, Capsicum chinense).
2. Harvest stage and color: green, breaker, or fully colored. Ripeness changes flavor, color and heat.
3. Form: whole with stems, destemmed, sliced or diced; for frozen, whether pieces are individually frozen.
4. Size or grade, if the supplier grades. Oklahoma State, for instance, notes a minimum size of 2.5 inches in diameter and length for U.S. No. 1 bell peppers [3]; hot types are often sold ungraded.
5. Defects allowed: decay, soft spots, sunscald, insect damage, foreign material.
6. Temperature at shipping and on arrival (see the inspection section).
7. Heat, if it matters to you: a target range in Scoville Heat Units measured by HPLC under ASTA Method 21.3 [4], or agreement to a reference sample. The USDA lets buyers set pungency either way for hot sauce, and notes that vendors' pungency ranges vary greatly [2].
8. Pack and weight: case size, net weight, and how weight is checked.
9. Lot coding and traceability: a lot or harvest code on every case, so you can tie peppers to your batch records.
10. Food safety: the grower's or supplier's food safety practices and any audit they hold.

For mash, paste and puree

Everything above, plus:

• Salt percentage, with a tolerance. Salt in the mash becomes salt in your sauce. How salt works in a ferment is on how much salt to use.
• pH and any added acid (vinegar or citric acid), and whether the product is fermented, acidified, or both.
• Age or fermentation time. Commercial mash is aged anywhere from 2 weeks to 3 years, and its aroma changes over that time [1].
• Preservatives, if any.
• Solids or seed and skin content, if your texture depends on it.
• Storage conditions and shelf life once opened.

Tell your process authority if you change from fresh peppers to mash, or from one mash to another. The salt, acid and pH of the mash are part of your formula. See turning a recipe into a product formula.

For dried chiles and powders

• Moisture content. Dried chiles are typically held at 10 to 15 percent moisture [5].
• Freedom from mold, insects and foreign material.
• Heat and color, if they matter.
• Never accept decorative or lacquered pods for food. Lacquered ristras are not safe to eat [6].

Inspecting a delivery

Inspect every lot as it arrives, before it goes into storage, and write down what you found. A rejected lot is far cheaper than a ruined batch.

Fresh peppers

1. Check the temperature. Fresh peppers keep best around 45°F (7 to 7.5°C); UC Davis gives 3 to 5 weeks at 45°F for bell peppers [7], while a separate storage chapter gives 2 to 3 weeks at 45°F with a good range of 45 to 55°F because some varieties are chilling-sensitive [5]. Oklahoma State gives 50 to 54°F at 90 to 95 percent relative humidity for up to two weeks [3]. The sources agree that peppers are injured below about 45°F [3][5]. Injury shows after a few days at 32°F or a few weeks at 41°F, so a load that looks fine on arrival can fail later [5].
2. Look for chilling injury. Surface pitting, water-soaked patches, decay (especially Alternaria), discolored seed cavities, and softening without water loss are the signs [7][5]. Green peppers are more sensitive than ripe ones [7].
3. Check ripeness and color against your specification. A mix of green and red in a "red" order changes color and flavor.
4. Cut a sample. Open 10 or so pods from different cases and look inside for mold, rot or insect damage.
5. Weigh. Check net weight on a few cases against the invoice.
6. Record the lot code, date, temperature, what you checked and who checked it.

Frozen peppers

• Product should arrive hard frozen, with no signs of thawing and refreezing (large ice crystals, clumped pieces, frost inside the bag).
• Check the pack date and lot code.
• Move it to your freezer at once.

Mash, paste and puree

• Containers sealed, undamaged, and labeled with product, lot and date.
• Check pH and taste for a fresh container; compare with the certificate or specification if the supplier provides one.
• Look for swelling, leaks or off odors. A swollen pail of fermented mash may be active fermentation, but it is a reason to call the supplier before you use it.

Dried chiles

• Look and smell for mold or mustiness; reject lots with visible mold.
• Snap a few pods: properly dry pods are crisp or leathery depending on type, not soft and damp.
• Check for insects and foreign material.
• Store at low humidity: a storage chapter for dried chiles recommends 60 to 70 percent relative humidity, with 6 months possible in nonrefrigerated warehouses and 6 to 9 months at 32 to 39°F with liners [5].

Building a supplier relationship

The best supply arrangements are simple and written: a specification, a price for the season or the quarter, a delivery schedule, and a named person to call when something is off. Ask growers early, before planting, if you want a variety grown to order. Keep a retained sample of each lot you accept, frozen, so you can compare the next one. That sample is also the start of the heat-matching routine on why the same recipe comes out hotter or milder.

From the loading dock to the cooler

Peppers that pass inspection still have to wait for production day, and the choice between refrigerating, freezing, salting into mash and drying changes the sauce. Compare them on storing peppers until you make sauce. If you plan to age a mash yourself rather than buy it, see aging a mash for months or years.
