Brown lentils are the workhorse of the lentil trade. They hold their shape better than red lentils, they are cheaper to prepare because they need no dehulling, and they cook without the disintegration that makes red lentils useful for purees and useless for a visible-particle product. Almost every canned lentil, most industrial soups with recognisable lentils in them and the bulk of food-service dry lentil volume is brown.
Ukrainian brown lentil area sits mainly in the central and eastern forest-steppe, with a secondary block in the northern steppe where the crop is grown in rotation ahead of winter wheat. The Ukrainian crop is a comparatively young one in commercial terms, which has two consequences for a buyer. Positively, the processing base that was built for the export trade is modern, so cleaning lines are typically equipped with gravity destoners and full-colour optical sorters rather than screens alone. Negatively, varietal discipline is looser than in Canada or Turkey, so lots can carry more size and colour variation than the equivalent origin elsewhere and the sample matters more than the label.
This record describes what a brown lentil lot actually looks like in specification terms, what an intake laboratory checks and where the cost sits. For the split versus whole decision see the split and whole comparison, and for the colour question see the red and green lentil note.
Grades, cuts and calibration
Brown lentils are graded on three axes at once, and a contract that names only one of them is incomplete.
Calibre. Sieve fractions are the primary commercial split. Large brown lentils command a different buyer set from small brown, because canners want a visible particle that survives retorting while soup blenders often prefer the small fraction for faster hydration. Calibre is declared as the sieve aperture through which the lot is retained, tested using a nested sieve set to size grading practice under ISO 3310 sieve specifications. A calibre claim with no sieve reference is a marketing statement.
Colour. Brown covers a range from pale khaki to a deep reddish brown. Uniformity matters more than the shade itself: a canner can work with any consistent shade and cannot work with a lot that looks like two lots mixed. Pulse colour sorting removes the off-colour tail, and the residual off-colour count is the number that belongs in the specification.
Soundness. Splits, broken cotyledons, shrivelled seed, insect-damaged seed and foreign matter are counted separately against a defined sample mass. Codex Standard CXS 171 for certain pulses provides the framework of defect categories; the numerical tolerances belong in the contract, because commercial practice is generally tighter than the Codex framework requires.
Machine capability sets what is realistically achievable. A line with destoning, gravity separation, indent cylinder and two passes of optical sort can deliver a genuinely clean product; a line with screens and one optical pass cannot, no matter what the contract says. Ask which unit operations the lot passed through rather than asking for a tolerance.
Seasonality and availability
Harvest runs from mid July into August depending on latitude and season. The crop is combined at a moisture level that usually needs a drying pass before it goes into long store, and that drying pass is where quality is won or lost. Dried too aggressively and the seed coat cracks, which shows up later as splits and as a lot that cooks unevenly; dried too little and the lot heats.
Cleaning and grading are done to order rather than at harvest, so shipping runs year round out of store. Practical consequence for a buyer: the September to December window offers the widest choice of lots and the best chance of matching a specific calibre profile, while the May to July window before new crop is when carry-over stock has been picked over and calibre availability narrows. Contracts that specify a tight large-calibre fraction should be placed early in the marketing year.
Old crop is not automatically inferior. A lot that has been stored cool and dry for eight months will outperform a badly handled new-crop lot. What changes with age is cook time: older lentils hydrate more slowly and can need a longer soak or cook, which matters to a canner running a fixed retort schedule. Declare harvest year on the certificate of analysis and treat cook time as a tested parameter rather than an assumption.
What the buyer checks at intake
- Moisture against the contract figure, with the reference method named. A lot shipped wet will heat in the container and arrive with mould and a smell that no downstream cleaning removes.
- Foreign matter, split and broken counts, and stones, each against a defined sample mass and a named method rather than a bare percentage.
- Insect activity, live and dead, plus evidence of the storage regime. This is the single most common rejection cause in the pulse trade.
- Colour uniformity and off-colour count, assessed under a defined light source rather than on a warehouse floor.
- Odour. Dry pulses pick up taint readily, and a musty or chemical smell at intake is a fatal defect regardless of the analytical results.
- Cook time against the contract figure, run on the buyer’s own water. Water hardness changes hydration behaviour materially, so a supplier cook test and a buyer cook test can legitimately differ; agree whose water is the reference.
Where it is used
Canning. The largest single outlet. The canner needs a lentil that reaches full hydration inside the retort schedule without breaking up, and needs consistency lot to lot because the schedule is fixed. Calibre uniformity does more for a canner than any other single parameter.
Soup and ready meals. Industrial soup producers use brown lentils where the recipe calls for visible particles. Here the sensitivity is to stones and foreign matter, because a hard foreign body in a finished retail soup is a recall event rather than a quality complaint.
Food service. Catering and institutional buyers take 25 kg bags and prepare from dry. Their complaint profile is dominated by uneven cook, which usually traces back to mixed calibre rather than to the lentil itself.
Retail packing. Private-label packers take cleaned bulk and pack to their own artwork. The pack is what the consumer inspects, so off-colour and split tolerances are tighter here than for any industrial outlet, and rejection is usually visual rather than analytical.
Milling. Off-calibre and lightly damaged fractions that fail a visual outlet go to pulse flour. This is the reason a cleaning line can run tight visual tolerances without destroying its own economics, and it is discussed in the pulse flour and protein guide.
Standards and routes
Brown lentils move as ambient dry cargo in standard containers. There is no cold chain, which makes the route decision a straight cost and transit-time question rather than a risk question. Central and northern European destinations go by road; volume to Turkey, the Levant and North Africa goes through the Black Sea ports, typically via Istanbul or Mersin.
The documentary set is the standard Ukrainian food export pack plus a phytosanitary certificate. Where wood pallets or dunnage are used they must be treated and marked under ISPM 15. The controls at the Union border follow Regulation (EU) 2017/625; consult the current consolidated text and the importing member state’s arrangements rather than relying on a figure quoted in a trade article.
Contractual framework is normally GAFTA for bulk and container pulse trade. See the GAFTA contract terms record for what the standard forms actually allocate between buyer and seller, and the Codex pulses standard record for the quality framework.
