Viticultural Practices
A study guide to how growers farm — the spectrum from conventional through sustainable and organic to biodynamic, what each allows, and how it connects to natural wine.
Every grower makes a choice about how to farm, and it runs along a spectrum from heavy intervention to almost none. At one end is conventional farming — reach for the chemical whenever there's a problem. At the other are organic and biodynamic growing, which ban or minimise synthetic inputs and lean on the vineyard's own ecosystem. In between sits sustainable viticulture, the pragmatic middle. Where a grower stands on that spectrum shapes not just the vine's health but the character — and the story — of the wine.
The framing idea: farming is a spectrum from "spray the problem" to "build a system that doesn't have the problem." The greener end costs more effort and accepts more risk, betting that healthier soil and biodiversity make better, more honest wine. Learn what each approach permits, and you can read the philosophy behind a bottle. (Part of the Grape Growing library; this is where natural wine begins — natural winemaking is built on this farming.)
The one thing to fix first: it's a spectrum, not four boxes
Don't memorise four rigid categories — memorise a line of increasing restraint: conventional (most intervention) → sustainable → organic → biodynamic (most restraint, most philosophy). Each step removes tools and adds reliance on the ecosystem. Fix that direction and the details slot in.
The four approaches at a glance
The memorise-cold table:
| Approach | Core idea | Chemicals |
|---|---|---|
| Conventional | Fix each problem with a product | Synthetic pesticides, fungicides, fertilisers — freely |
| Sustainable | Rational, minimal intervention | Reduced, targeted; IPM; monitor and justify |
| Organic | No synthetic inputs | Banned synthetics; limited natural treatments; certified |
| Biodynamic | Organic plus a whole-farm philosophy | As organic, plus lunar calendar & preparations |
Key facts
| The spectrum | Conventional → sustainable → organic → biodynamic |
| Conventional risk | Over-application of sulphur/copper and fertiliser → environmental harm |
| Sustainable tool | IPM — predators over sprays; biodiversity over monoculture |
| Organic mark | Certification/accreditation; synthetics banned; low/again-limited SO₂ |
| Biodynamic figures | Rudolf Steiner (founder) and Maria Thun (the calendar) |
| The link | The farming base of natural wine |
The vocabulary you'll actually meet
- Certified organic / biodynamic — verified by an accreditation body (labels like EU organic leaf, Demeter for biodynamic); "organic" on a wine is a regulated claim, unlike "old vine".
- IPM (Integrated Pest Management) — using natural predators and monitoring to minimise spraying (see pests & disease).
- Monoculture vs biodiversity — wall-to-wall vines vs a living system of cover crops, hedges and insects.
- Preparations — the biodynamic composts and sprays (e.g. "500", horn manure).

The four approaches in depth
- Conventional. The default of the 20th century: synthetic pesticides, fungicides and fertilisers, applied as problems arise, with heavy reliance on chemical fertiliser and mass-produced products. It's cheap, reliable and short-term in outlook — and its cost is environmental: over-application of sulphur, copper and fertiliser damages soils and waterways over time.
- Sustainable. A pragmatic reform rather than a ban. Growers are encouraged to understand the vine and the site, monitor weather forecasts, maintain biodiversity, and use agrochemicals only logically and sparingly when truly needed. Its signature tool is IPM (Integrated Pest Management) — encouraging pests' natural predators to live in the vineyard, and favouring biodiversity over monoculture.
- Organic. A regulated step further: synthetic pesticides, fungicides and fertilisers are banned, and only a limited list of natural treatments is allowed (copper and sulphur among them, in capped amounts). It requires certification/accreditation, sets lower limits on SO₂, and earns a label. The trade-off is more risk and labour for a cleaner system.
- Biodynamic. Takes organic farming as its base and adds a whole-farm philosophy developed by Rudolf Steiner, with the planting-and-treatment calendar popularised by Maria Thun. The farm is treated as a single living organism, with special composts and preparations applied according to lunar and cosmic cycles. The science is debated; the results, in careful hands, are often excellent — partly because it forces meticulous attention.
Practice → vineyard → wine
| Practice | Effect in the vineyard | Effect on the wine (and its story) |
|---|---|---|
| Conventional | Reliable, low-labour, higher yields | Consistent, cheap; environmental cost |
| Sustainable | Healthier ecosystem, less spray | Cleaner farming, mainstream quality |
| Organic | Living soil, more risk/labour | A certified claim; often more site character |
| Biodynamic | Meticulous, holistic care | A philosophy in the bottle; frequently high quality |
How this connects to natural wine
This page is the vineyard half of a story the cellar finishes. Organic or biodynamic farming is the starting requirement for natural wine — the low-intervention movement that then carries the same "add as little as possible" philosophy into the winery (wild yeast, minimal or no added sulphur, no fining or filtering). You can farm organically and still make wine conventionally; but you cannot make natural wine without farming this way first. Farming is where it all begins.
Classic exam questions
- Name the farming spectrum from most to least intervention. — Conventional → sustainable → organic → biodynamic.
- What's the main criticism of conventional viticulture? — Over-application of synthetic chemicals and fertiliser, causing environmental damage.
- What defines sustainable viticulture? — Minimal, rational intervention: IPM, biodiversity, monitoring — chemicals only when justified.
- What does organic certification forbid and require? — Forbids synthetic inputs; requires accreditation and limited natural treatments (lower SO₂).
- Who are the key biodynamic figures? — Rudolf Steiner (founder) and Maria Thun (the calendar).
- How does biodynamic differ from organic? — It adds a whole-farm philosophy and a lunar/cosmic calendar on top of organic practice.
- How does farming relate to natural wine? — Organic/biodynamic farming is the prerequisite for natural wine, which extends the same restraint into the cellar.
Farming is the first and longest decision in a wine's life — everything the winemaker does later is built on the choice the grower made in the vineyard.
