3.1 Vine Identity and Vineyard Management Approaches

Human decisions in the vineyard start with what is planted and how it is farmed. WSET Level 3 expects you to separate vine identity (species → variety → clone; crossings vs hybrids) from management philosophy (conventional, sustainable, organic, biodynamic), and to know how vine structure maps onto training and pruning choices in the next section.

Species and Variety: Why Vitis vinifera Dominates

Nearly all quality wine is made from Vitis vinifera, the Eurasian wine grape species. Other Vitis species (for example V. labrusca, V. riparia, V. rupestris) matter mainly as rootstocks or breeding parents, not as mainstream wine varieties in classic European regions.

A grape variety (cultivar) is a distinct genetic type within the species — Cabernet Sauvignon, Riesling, Tempranillo. Each variety has a characteristic cluster of traits: ripening date, berry size, skin thickness, acid retention, aroma precursors, disease susceptibility, and yield potential. Those traits interact with climate and site (Chapter 2) to set style potential; human factors then decide whether that potential is realised.

Clones

A clone is a genetically identical selection propagated from a single mother vine chosen for desirable traits (yield, bunch architecture, flavour intensity, virus status). Pinot Noir and Chardonnay illustrate why clones matter: different Dijon or Champagne clones can shift bunch size, ripeness timing, and disease pressure in the same vineyard. Clonal selection is not the same as a new variety — it is fine-tuning within one variety.

Crossings vs Hybrids (High-Yield Exam Distinction)

Trap: students often call any new vine a “hybrid.” If both parents are vinifera, it is a crossing, not a hybrid.

Vine Structure: Green Parts, One-Year Wood, Permanent Wood

Understanding structure is essential because pruning removes wood by age class, and training shapes permanent wood.

Green Parts (Current Season Growth)

• Shoots — green, leafy growth of the current year; carry leaves, tendrils, and eventually flower clusters that become bunches.
• Leaves — the photosynthetic engines; canopy density and leaf health control sugar production, shade, and disease microclimate.
• Flowers / bunches — reproductive organs; fruit set success affects yield and bunch compactness.
• Tendrils — help the vine climb or attach to wires.

Green tissue is soft, photosynthetic, and vulnerable to spring frost, hail, and many fungal pathogens.

One-Year Wood

After leaf fall, the lignified shoot becomes one-year-old wood (canes). This wood carries the buds that will produce next season’s shoots and fruit. Winter pruning decisions are largely about how much one-year wood to keep and where to position it.

Permanent Wood

Permanent wood is the lasting framework: trunk, and any arms or cordons retained year after year. Training systems decide the geometry of that framework (head vs cordon — Section 3.2). Permanent wood stores carbohydrates, supports vascular flow, and is the vine’s long-term “skeleton.”

Vineyard Management Approaches

Growers choose a farming philosophy that constrains which inputs and practices are allowed. For the exam, know the intent, typical restrictions, and common confusion points — especially organic vs biodynamic.

Conventional

Conventional viticulture uses the full toolkit of modern agrochemicals where permitted: synthetic herbicides, insecticides, fungicides, and fertilisers, plus irrigation and mechanisation as needed. Goals are usually reliable yield, disease control, and cost efficiency. Risks of overuse include soil compaction, reduced biodiversity, resistance in pests/pathogens, and residue or environmental concerns. Conventional does not mean “careless”; many conventional estates still practice careful canopy work and targeted spraying.

Sustainable

Sustainable viticulture aims to reduce chemical and environmental impact while remaining economically viable — often via integrated pest management (IPM), cover crops, monitoring thresholds before spraying, and water/energy efficiency. There is no single global legal definition; schemes and logos vary by country (for example regional sustainability certifications). Exam angle: sustainable is a direction and toolkit, not a fixed ban list like organic certification.

Organic

Organic viticulture (and organic wine rules, which can differ slightly by jurisdiction) generally prohibits synthetic herbicides, insecticides, and fertilisers. Copper- and sulphur-based fungicides are typically still allowed within limits because fungal disease pressure is real, especially in humid climates. Weed control shifts to tillage, mowing, or cover crops; nutrition relies on composts and organic amendments. Certification bodies audit practices. Organic is about allowed inputs and soil/ecosystem rules, not mystical timing.

Biodynamic

Biodynamic agriculture follows organic-style bans on synthetic agrochemicals and adds the philosophy of Rudolf Steiner: the farm as a self-sustaining organism, use of biodynamic preparations (for example cow-horn manure preparation 500, silica preparation 501), and often planting/spraying timed to lunar and cosmic calendars. Composting and biodiversity are emphasised. Certification (for example Demeter) is separate from organic certification.

Exam Trap: Organic vs Biodynamic

• Organic ≠ biodynamic. All biodynamic estates are effectively organic in input bans, but organic estates are not automatically biodynamic.
• Biodynamic’s distinctive exam markers are preparations and cosmic/lunar timing, not merely “no chemicals.”
• Neither approach automatically equals higher quality — they change vineyard ecology and costs; quality still depends on site, variety, yield, and harvest decisions.

Linking Identity to Practice

Variety and clone choice set disease susceptibility and ripening window; rootstock choice (often driven by phylloxera and soil — Section 3.3) sits under the graft. Management approach then constrains how hazards and pests are fought. Training and pruning (next section) operate on the permanent and one-year wood of whatever was planted. For SAQs, be ready to explain why a grower might choose a disease-resistant crossing/hybrid in a humid cool climate, or why a Bordeaux estate might stay conventional yet still thin shoots and leaf-pluck for quality.

Key Takeaways

• Wine grapes are overwhelmingly V. vinifera varieties, refined by clones; crossings stay within vinifera, hybrids cross species lines.
• Structure: green parts (season), one-year wood (buds for next crop), permanent wood (framework).
• Farming ladder: conventional → sustainable (reduce) → organic (ban synthetics) → biodynamic (organic + preparations/calendar).
