1.9Harvesting and handling procedures


The timing of harvest is largely determined by status of the fruit with colour, gloss, size and sugar-acid ratio used as indicators. A lower sugar ratio may be used as the harvest index depending on the cultivar (Table 3.3).

Table 3.3 Sugar ratio and maturation period harvest index (NPQS 2011).

Fruit is harvested in the morning if the weather is sunny. Grape bunches are cut from the plant with pruning scissors and stored in a harvest box. Fruit is not packed too tightly to prevent berries from dropping or clusters becoming damaged, and is generally piled 2–3 levels high (Figure 3.18). Harvested fruit is stored under shade to keep it cool until it is transferred to the packhouse (NPQS 2011).

1.10Post-harvest

1.10.1Packing house

Pre-cooling and sorting


Fruit is pre-cooled following harvest. Using pre-cooling boxes, fruit temperatures are dropped from 30 °C to 4–5 °C by forced air cooling for 4–6 hours, or by static pressure air cooling for 1–2 hours (NPQS 2011).

Trained sorting experts supervise the sorting process (NPQS 2010b).
Any unripe, small or dehiscent berries are removed during sorting. Grapes are manually sorted by quality and the size of berries (Figure 3.19).

Packing and storage
Packing is carried out to minimise damage to fruit while being convenient for transport and sale. Grapes are packaged in corrugated cardboard boxes holding 4–10 kg (Figure 3.20) (NPQS 2011). These boxes are designed to prevent pest entrance and those with vent holes are covered with vinyl after packing to prevent pest entrance (NPQS 2010b). Grapes are placed in cold storage prior to export at 0 C to -5 °C ± 0.5 °C and 80–90% humidity (NPQS 2011).

1.10.2Export procedures


Upon receipt of application for an export inspection, a plant quarantine inspector will visit the site where the consignment is located. The inspector samples 2% of the total consignment and inspect for pests with a magnifying glass (Figure 3.22) in accordance with the official export inspection procedures of Korea (NPQS 2010b; NPQS 2011). If any pests are detected during this process then remedial action will be taken. This may vary depending on the pest and may inlcude treatment, shipment to an alternative market or suspension of the vineyard from the export program for an appropriate period (NPQS 2010b; NPQS 2011). If no pests are detected, the consignment will be issued with a phytosanitary certificate.

1.10.3Transport


Grapes will be transported to Australia using air and sea freight.

1.11Export capability

1.11.1Production statistics


Exports account for approximately 0.1% of total grape production in Korea. Each year there is a gradual increase in the number of countries importing Korean grapes and an increase in export volume. Exports increased from 68 tonnes in 2004 to 340 tonnes in 2008 (Table 3.4). Figure 3.23 displays production ratios in the Korea by region (NPQS 2011).

1.11.2 Export statistics


Korea currently exports grapes to the USA (including Guam and Saipan), Japan, Indonesia, Malaysia, Hong Kong and Singapore. Major export markets and volumes are summarised in Table 3.5. The USA is the largest export market with approximately 310 tonnes of grapes exported in 2009.
At present, the volume of table grapes likely to be exported to Australia from Korea cannot be accurately forecast, but preliminary advice from NPQS suggest it is likely to be around 50 tonnes per year (NPQS 2011).

1.11.3Export season


Table grapes for export from Korea are usually harvested and exported between August and October each year. Specific timing is dependant on the cultivar and growing area (NPQS 2011).
