Harvesting and preparation by us:

Fresh grapes with a preferred minimum sugar content of 20 Brix is harvested and pre-treated in an emulsion of potassium and sultana oil to assist in the drying process. The grapes are then evenly packed on stacked wooden drying trays before being fumigated in a Sulphur chamber for at least six hours.

After this process we air-dry the raisins for 10 – 14 days. Then the raisins are being processed in the factory plant, ready for packaging and shipping.
