Dried dill weed is the leaf and the tender upper stem of Anethum graveolens, cut green, dried down to a stable moisture and then cut and sifted into a defined particle size. It is not the same product as dill seed, which comes from the same plant at a later growth stage, carries a completely different volatile oil profile and sells into a different application. A specification that says only ‘dill’ will get one of the two, and which one depends on the seller.
Ukraine is a significant origin for the leaf because the crop suits the climate, the field to dryer distance is short, and the drying capacity sits close to the growing area. Short field to dryer time is the single biggest determinant of colour and of retained volatile oil, so proximity is a real quality variable rather than a logistics convenience.
Grades, cuts and calibration
Grading runs on four axes at once, and a buyer who fixes only one of them will be surprised by the other three.
Cut size. The trade names are conventions, not standards. Particle size is the honest way to write it: a specification that names a sieve fraction, for example ‘passing 4.0 mm and retained on 1.0 mm, with a stated maximum fines percentage’, is enforceable. A specification that says ‘tea bag cut’ or ‘standard cut’ is not, because those words mean different fractions in different houses. Fines matter commercially as well as visually: they carry a higher stem and dust share and they segregate in transit.
Colour. A bright green is the visible proxy for gentle drying and short field time. It is normally assessed against a retained reference sample rather than by instrument, though colour measurement in a defined colour space is available and is worth using where two origins are being compared. Olive or yellow-green means heat, delay or long storage in light.
Leaf to stem. Stem is not a defect, it is a yield question. Stem carries less volatile oil, weighs more per unit of flavour and looks coarse in the pack. Buyers who care write a maximum stem percentage; buyers who do not will get whatever the sifting line delivers that week.
Volatile oil. The volatile oil content is what the product is actually bought for, and it is the axis most often left out of the specification. It is reported on a dry basis, so it has to be read together with the moisture figure or the comparison is meaningless.
Seasonality and availability
Dill is cut two or three times in a season that runs from May into September, with the first cut generally giving the best colour and the cleanest leaf. Material is dried within hours of cutting, then held in conditioned bulk and cut, sifted and packed to order, which is why the product is available all year even though the crop is not.
Crop year matters more than month of shipment. A wet season raises the soil load on the leaf, which shows up as acid-insoluble ash rather than as anything visible, and it raises the microbiological starting point. A dry season gives cleaner leaf and better colour but lower yield, which shows up in price. Ask which cut a sample came from and which cut the offered lot comes from; they are not the same material.
What the buyer checks at intake
- Identity and lot: species and plant part on the label, crop year, cut number and the establishment approval number of the processor, checked against the packing list.
- Particle size against the agreed sieve fraction on a representative composite, not on a handful from the top of one bag, with the fines share recorded.
- Colour against the retained reference sample under consistent light, and a note on whether the sample is from the same crop year.
- Moisture and, where the specification carries it, water activity, because a lot that passes on moisture can still sit above the mould growth threshold.
- Extraneous and foreign matter on a weighed sample, separating plant material of other species from mineral matter, because the two have different causes and different remedies.
- Volatile oil on the certificate of analysis, cross-read against moisture, and a sensory check for the characteristic aroma with no hay, musty or scorched note.
- Treatment status stated in writing: untreated, steam treated, or irradiated. This determines the label and cannot be resolved after the goods arrive.
Where it is used
Food service and industrial kitchens are the largest outlet, where dill goes into soups, sauces, dressings, marinades and fish preparations, usually in a medium cut that stays visible in the finished dish. Retail private label takes a finer, more uniform cut in glass or in a laminate sachet, and is the most colour-sensitive channel because the consumer sees the product through the pack.
Seasoning blends for snacks, crisps and coated products take dill in a fine cut or ground, where dispersion and freedom from stem matter more than appearance. Pickling and vegetable preserving take a coarser cut and in some cases the seed rather than the leaf. Frozen and chilled ready meals use dill as a finishing herb, which puts the emphasis back on colour retention after heat.
Standards and routes
Dill is an ambient dry good. It travels in standard curtainside road trailers or dry containers, with no temperature control required, but it is hygroscopic, so the real transport risk is moisture pick-up rather than temperature. The barrier is the pack, not the vehicle: a polyethylene liner inside a carton is the minimum, and a foil laminate is worth the cost where the lot will be stored for months before use.
Road corridors to Poland and the Netherlands carry most of the volume. The documentary chain is the standard third-country set covered in the export documentation guide. Supplier assurance normally runs through BRCGS or IFS Food; the herb-specific detail sits in the herb drying guide.
