Two different berries are traded in Europe under the same English word. The cultivated large cranberry, Vaccinium macrocarpon, is a North American species grown on engineered peat beds and flood harvested. The wild bog cranberry, Vaccinium oxycoccos, is a native European species that grows on undrained sphagnum peatland and is picked by hand or with a comb rake. Ukraine supplies both, but its distinctive product is the second one, gathered across the Polissia wetlands of Volyn, Rivne, Zhytomyr and northern Kyiv oblast.
The two are not interchangeable in a specification. Wild bog cranberry is markedly smaller, noticeably more acid, and deeper in colour for the same weight of fruit. Buyers formulating on colour or on acidity will get a different result from the same inclusion rate, which is why the species name belongs in the contract rather than the word cranberry on its own.
Grades, cuts and calibration
Species and origin type. State whether the contract is for wild oxycoccos, cultivated macrocarpon, or a declared blend. This is the first line of the specification and the one most often left out.
Firmness. Cranberry is one of the few fruits still graded partly by bounce. A sound berry has enough internal gas to rebound off an inclined baffle; a soft or frost-damaged one does not. Bounce separation is crude but it removes the defect class that matters most, and it runs ahead of optical sorting rather than instead of it.
Colour. Graded by surface colour on the colour sorter and increasingly confirmed by anthocyanin assay where the buyer is using the fruit as a colour carrier. Wild crop runs deeper and less uniform than cultivated; a tight colour band on wild fruit costs yield and should be priced as a sorting decision, not assumed.
Size. Reported as a berry count per 100 grams rather than a diameter, because the fruit is not spherical. Size grading matters for retail packs and for visible inclusion in bakery; it is close to irrelevant for juice and puree.
Defects. Stalk, leaf and moss are the characteristic wild-crop carry-over. A defect table should name them separately from soft and split fruit, because they are removed by different equipment and a single combined percentage hides which one is failing.
Seasonality and availability
Wild harvest opens in the second half of September and runs to the first hard frost. A second, smaller gathering takes place in early spring on fruit that over-wintered under snow; that fruit is sweeter, softer and lower in acid, and it should be contracted as a separate article rather than blended into an autumn specification without disclosure.
Harvest timing on wild crop is weather bound and the gathering workforce is seasonal and dispersed, so volume in any given year is genuinely uncertain until the crop is in. Cultivated beds are far more predictable but represent the smaller share of Ukrainian output.
The practical consequence for a buyer is that cranberry behaves like a wild crop commercially even when the harvest year looks normal. Volume for a full processing season should be committed before or during harvest. Spot purchase in June works only for whatever is left in store.
What the buyer checks at intake
- Species declaration and gathering area, cross-checked against the collector documentation. On wild crop this is the traceability record, and it is thinner than an orchard record by nature.
- Radiological certificate where the fruit originates from the Polissia collection zones. This is a standing requirement on Ukrainian wild forest and bog produce and it should be treated as a routine document, not an exception.
- Firmness and soft-berry percentage on a thawed sample against the defect table.
- Extraneous vegetable matter by weight, counted separately for stalk, leaf and moss.
- Colour, either instrumentally or against retained standards, plus soluble solids and titratable acidity as a pair. Cranberry is bought for acid as much as for colour and one figure without the other is not informative.
- Certificate of analysis covering residues, heavy metals and the agreed microbiological panel.
Where it is used
Beverage is the largest outlet. Cranberry goes into juice concentrate for single-strength reconstitution and into blends where it supplies acidity and a red that survives pasteurisation better than most fruit reds. The compositional conventions that govern how that juice may be described are commercial rather than statutory in part, and are set out in the concentrate sourcing guide.
Sweetened dried cranberry is the second major channel. The fruit is infused with a sugar syrup to counter the acidity and then dried, which is a different industrial process from the sulphited drying used on stone fruit and produces a different labelling position. Frozen whole fruit is the usual raw material for it.
Bakery uses whole and halved frozen berries in muffins, breads and fruit bars, where the acidity is the point. Dairy takes it into fruit preparations, usually blended with a sweeter fruit. Retail private label sells single-fruit frozen packs into the autumn and winter seasonal slots in Central and Northern Europe.
Standards and routes
Standard frozen carriage in a reefer or a reefer trailer at minus 18 degrees Celsius or colder. Cranberry is a robust berry by frozen-fruit standards, with a firm skin and low free water, so it survives handling better than raspberry or pear; a temperature excursion still has to be recorded and assessed.
The Polish corridor carries most volume, with Germany and Czechia the other main destinations. Because the collection areas sit in the north-west of the country, the road distance to the EU border is short and pre-cooling at the freezer, rather than in transit, does the work.
Documentation follows the standard export set described in the documentation guide, plus the radiological certificate on Polissia wild crop. Buyers who have not handled Ukrainian wild produce before should build that document into the checklist at contract stage rather than discover it at the border.
