Table grapes and wine grapes are distinct commercial categories with different variety requirements, production practices, and buyer profiles. Table grapes are selected for seedlessness (Thompson Seedless/Crimson/Arra), large berry size (≥18 mm diameter for Class I), Brix ≥16°, uniform bunch weight (300–500 g per bunch), firm texture for transit, and visual appeal. Wine grapes (Cabernet Sauvignon, Chardonnay, Merlot, Shiraz) are selected for sugar/acid balance, skin phenolics, and aromatic character. Wholesale buyers in the fresh produce trade source table grapes; wineries source wine grapes through entirely separate agricultural supply chains. IQF frozen grapes (seedless Thompson and Crimson) represent a growing third category primarily used by smoothie manufacturers and food service.
Key Commercial Table Grape Varieties
Thompson Seedless (Sultana): the world's most widely-planted table grape variety; green/yellow-green, elongated berry, Brix 16–18°; origins include USA (California), Chile, South Africa, India, and Turkey. Crimson Seedless: dark red, large berry, excellent shelf life, Brix 16–18°; major origins are USA, Chile, and South Africa. Red Globe: large, seeded, deep red — dominant in Asian markets (China, Vietnam, Thailand) where seeded grapes remain preferred. Arra varieties (Arra 15, Sweet Globe, Sweet Celebration): proprietary Arra/IFG breeding program varieties increasingly planted in South Africa, Chile, and Peru; typically very large berries, extended shelf life, superior flavour. Ralli (Muscat Hamburg derivatives): regional varieties in Turkey and Italy. Autumn Royal (black seedless): late-season supply extension from California and Chile.
Quality Specifications and EU Marketing Standards
EU Commission Delegated Regulation 2019/428 defines marketing standards for table grapes under Class Extra, Class I, and Class II. Key requirements for Class I: minimum Brix 12° (EU standard; buyers typically set internal standards of ≥16°), bunch weight minimum 75 g, minimum berry diameter 12 mm for elongated varieties / 14 mm for round varieties, uniformity in colour, shape, and size. Defect tolerances define maximum limits for sunburn, shot berries, and raisining. South Africa uses a parallel grading system (Class 1/2/3) audited by PPECB inspection. Chile grades under SAG-audited protocols. For premium export, buyers commonly specify bunch weight ranges (200–500 g or 300–500 g), a minimum berry diameter (typically ≥18 mm), and Brix ≥16°.

Table grapes are cold chain-sensitive and highly susceptible to Botrytis cinerea (grey mould) during sea freight. Optimal transit temperature is −1°C to 0°C (must not drop below −2.5°C to avoid freeze damage). SO₂ (sulphur dioxide) slow-release generator pads are placed inside cartons to control Botrytis during 2–4 week sea freight. Pad types: fast/slow dual-release pads designed to release a high initial SO₂ dose on day 1–2 followed by slow-release maintenance over 3–4 weeks. SO₂ residue on berries must not exceed 10 mg/kg at consumer level (EU). Pre-cooling to 0°C within 4–6 hours of harvest via forced-air cooling is critical. Controlled atmosphere (CA) storage: 1–3% O₂, 3–5% CO₂, 90–95% RH extends shelf life significantly for CA-stored parcels held before export.
Key Export Origins and Certifications
South Africa (Western Cape — Hex River Valley, Berg River, Orange River): dominant southern hemisphere table grape exporter; GlobalGAP and SIZA social compliance mandatory for UK/EU supermarket chains; PPECB export inspection; window October–April. Chile (Atacama, Coquimbo, Maule): world's second-largest table grape exporter; ASOEX-represented; SAG phytosanitary; window November–April. Peru (Ica Valley): fastest-growing table grape exporter; Arra and IFG varieties dominant; Senasa phytosanitary; window October–February. Egypt (El Minya, Luxor, Assiut): competitive pricing, Red Globe and Thompson Seedless; window July–October. USA (California — San Joaquin Valley): Crimson, Thompson, Autumn Royal; window July–November. Italy and Spain: European-season supply May–November. Fairtrade certification available from South Africa (WIETA/Fairtrade) and Chile.
Frequently Asked Questions
What is the minimum Brix for export-grade table grapes?
EU marketing standards set a minimum of 12° Brix for Class I table grapes, but major European retail buyers typically specify a higher internal standard of ≥16° Brix for red and black varieties and ≥14° for green varieties. South African PPECB and Chilean SAG export inspections check against national grade standards, which generally align with EU minimums.
How are SO₂ pads used in grape export?
Sulphur dioxide slow-release pads are placed inside the grape carton (typically one dual-release pad per 4.5–10 kg carton) to control Botrytis grey mould during sea freight. They release an initial high-dose burst on day 1–2, followed by slow-release SO₂ over 3–5 weeks. The EU sets a maximum SO₂ residue limit of 10 mg/kg on grapes at retail — monitoring by importers ensures compliance.
What is the northern vs southern hemisphere supply window for table grapes?
Northern hemisphere origins (Spain, Italy, Turkey, Egypt, USA) supply from approximately May to November. Southern hemisphere origins (South Africa, Chile, Peru, Argentina, Namibia) supply from October to April. This creates year-round availability for buyers willing to switch origins seasonally. Peru and Namibia have extended early/late windows that overlap with both hemispheres.
What is PPECB certification for South African grapes?
The Perishable Products Export Control Board (PPECB) is South Africa's statutory inspection body for fresh produce exports. PPECB inspectors verify that grapes meet export grade standards (size, colour, defect tolerances, Brix) before container loading. A PPECB inspection certificate accompanies the export documentation. For EU/UK supermarket buyers, PPECB inspection is a minimum requirement; GlobalGAP and SIZA (social compliance) certification are additionally required.
Can I source Fairtrade-certified table grapes in bulk?
Fairtrade-certified table grapes are available from South Africa (several Hex River and Berg River producers are Fairtrade-certified through WIETA) and from Chile and Egypt. Fairtrade table grape supply is significantly smaller than banana supply — availability should be confirmed seasonally. Fairtrade Premium on table grapes is set by Fairtrade International and paid to the producer group for community development. UK and European retailers with Fairtrade commitments source through importers with FAIRTRADE Mark licensing agreements.
