Species, Propagation & Clones
A study guide to where vines come from — the one wine species Vitis vinifera, the American species behind rootstocks, why vines are cloned not seeded, and how mutation gives clones like the Pinot family.
Almost every wine you have ever drunk came from a single grape species, Vitis vinifera — the "wine-bearing" vine of the Old World. And almost every vine of a given variety is not a breed but a clone: a genetic copy of one original plant, propagated by cutting rather than grown from seed. Plant a Chardonnay pip and you get something new and unpredictable; take a cutting of a Chardonnay vine and you get Chardonnay, exactly, again.
The framing idea: a grape variety is a clone, not a breed. Because vines are propagated vegetatively (from pieces of an existing vine, not from seed), every Pinot Noir on earth is a descendant-by-copying of the same plant — which means the only way a variety changes on its own is by mutation, the slow genetic drift that gives us clones, and occasionally a whole new grape. Learn how vines are copied, and where clones come from, and the family tree of wine grapes stops being a muddle. (This is part of the Grape Growing library — see also anatomy of the vine.)
The one thing to fix first: vines are copied, not bred
Grapevines are propagated asexually — a grower takes a piece of one vine and grows a whole new plant from it, genetically identical to the parent. Sexual reproduction (a seed, from a pollinated flower) gives an unpredictable new individual — that's how you make a new variety (the subject of the crossings & hybrids page), not how you plant more of an existing one. So the working truth of the vineyard is: a "variety" is one genetic individual, copied endlessly, and it only drifts through mutation.
The species that matter
Wine is dominated by one species; a handful of others do essential work underground. The memorise-cold table:
| Species | Origin | Role in wine |
|---|---|---|
| Vitis vinifera | Europe / Near East (Old World) | The wine species — virtually every famous variety (Chardonnay, Pinot Noir, Cabernet…) is vinifera |
| Vitis berlandieri | North America | Rootstock parent — tolerates lime and phylloxera |
| Vitis riparia | North America | Rootstock parent — vigour control, phylloxera tolerance |
| Vitis rupestris | North America | Rootstock parent — drought and phylloxera tolerance |
The key idea: the American species are not used to make wine — their fruit is poor — but they are tolerant of phylloxera (the root louse that vinifera has no defence against), so they are bred into the rootstocks onto which wine vines are grafted. The grafting story is its own page (rootstocks & grafting); here they matter only as the species behind it.
Key facts
| The wine species | Vitis vinifera — nearly all wine grapes |
| The rootstock species | American berlandieri, riparia, rupestris — phylloxera-tolerant |
| How vines are planted | Vegetatively (cuttings/layering) → genetic copies, not seedlings |
| What a "variety" really is | One genetic individual, cloned — Chardonnay is a single plant, copied |
| The only in-variety change | Mutation → clones (and, rarely, whole new grapes) |
| Famous mutation family | Pinot — Noir, Gris, Blanc, Meunier are one grape's variants |
The vocabulary you'll actually meet
- Clone — a sub-type of a variety, propagated from one vine that carries a particular (often useful) mutation: e.g. a Pinot Noir clone selected for small berries and deep colour.
- Clonal selection vs sélection massale (mass selection) — buying a few certified, uniform clones from a nursery, versus taking cuttings from many of your own best old vines to keep genetic diversity. Two philosophies you'll meet in serious-wine writing.
- "Pinot Gris" = "Pinot Grigio" — same grape, a colour mutation of Pinot Noir; the label just reflects language and style, not a different vine.
- "Old vine" / vieilles vignes — often massale-selected, diverse plantings; as ever, the term is unregulated — a claim, not a guarantee.

Propagation, step by step
Two vegetative methods put a new vine in the ground — both give a genetically identical copy of the parent:
- Rooted cutting — the workhorse. A length of dormant one-year-old wood is cut from a chosen "mother" vine, encouraged to grow roots, and planted out (in phylloxera country, first grafted onto a rootstock — see below). It is the most productive and adaptable method: nurseries multiply a desirable vine into thousands of identical plants, and the grower controls exactly which variety, clone and rootstock goes where.
- Layering (provignage) — an in-vineyard trick: a cane from an existing vine is bent down and buried so it takes root while still attached to the mother, then severed once established. Handy for filling a gap next to a healthy old vine — but the new plant grows on its own vinifera roots, which are not phylloxera-tolerant, so layering is only safe in phylloxera-free soils (sandy sites, Chile, parts of Australia). Elsewhere it plants a victim.
The grafting caveat is the thread running through both: because vinifera roots have no answer to phylloxera, wine vines in most of the world are grafted — the fruiting variety (the scion) joined onto an American rootstock. Cuttings make that easy to control; layering doesn't. (The full mechanism is the rootstocks & grafting page.)
Propagation choice → vineyard → glass
| Choice | Effect in the vineyard | Effect in the glass |
|---|---|---|
| Rooted cuttings (grafted) | Precise control of variety, clone and rootstock; phylloxera-safe | Consistency; the foundation of modern quality |
| Layering (own-rooted) | Quick gap-filling from a proven neighbour; only safe phylloxera-free | Continuity of an old vine's character — where the soil allows |
| Single certified clone | Uniform ripening, predictable, disease-clean | Clean, consistent, sometimes too uniform |
| Sélection massale (many old vines) | Genetic diversity in the block | Complexity and layered flavour; a quiet quality marker |
Clones and mutation
Because a variety is one plant copied over and over, the only thing that changes it is mutation — a small genetic error that arises in a bud and is then carried forward every time that wood is propagated. Most mutations are neutral or harmful; occasionally one is useful.
- Clonal selection is the deliberate hunt for those useful mutations: a grower or nursery spots a vine (or a single shoot) with a desirable trait — smaller berries, deeper colour, earlier ripening, better disease resistance, higher or lower yield — and propagates only that, creating a named clone. Modern nurseries offer dozens per variety.
- Sélection massale is the older counter-approach: rather than buy a few clones, take cuttings from many of your own best vines, preserving the block's genetic diversity. It trades uniformity for complexity, and is prized by growers who think single clones make monotonous wine.
Pinot Noir is the textbook case: an ancient, genetically unstable grape with a huge number of registered clones, and the differences between them — in berry size, looseness of bunch, ripening — are large enough to change the wine noticeably.
The Pinot family: one grape, four faces
The most famous mutation story in wine is a single grape wearing several colours. Pinot Noir is the ancestor; the others are mutations of it, differing mostly in berry colour (and, for Meunier, hairy leaves), while remaining genetically almost the same vine:
- Pinot Noir — the black-berried original.
- Pinot Gris — a colour mutation to greyish-pink berries (Pinot Grigio is the same grape).
- Pinot Blanc — a further mutation to white berries.
- Pinot Meunier — a mutation with characteristic floury-white down on its leaves; a mainstay of Champagne.
They can even mutate back and forth, and a single vine can carry more than one colour — living proof that a "variety" is a genome one bud-mutation wide.
Worked examples
- Burgundy — clones vs massale. Burgundy growers argue endlessly over Pinot Noir and Chardonnay clones: certified clones for reliability and health, or sélection massale from old parcels for complexity. It's a live quality debate, not a technicality.
- Champagne — Meunier's insurance. Champagne leans on Pinot Meunier partly because this Pinot mutation buds late and ripens reliably in a frost-prone, marginal climate — the mutation earns its place agronomically.
- Phylloxera-free own roots. In sandy soils and countries phylloxera never fully conquered, vines can grow own-rooted (via cuttings or layering), keeping a direct genetic line to old plantings — a rare luxury elsewhere.
Classic exam questions
- What species are almost all wine grapes? — Vitis vinifera, the European wine species.
- What are the American species used for? — As rootstock parents (berlandieri, riparia, rupestris) — they're phylloxera-tolerant, so wine vines are grafted onto them.
- How are vines propagated, and what does it produce? — Vegetatively, by rooted cuttings or layering — giving genetically identical copies of the parent.
- Why is layering risky? — The new vine grows on its own phylloxera-prone vinifera roots, so it's only safe in phylloxera-free soils.
- What is a clone? — A sub-type of a variety propagated from a vine carrying a particular mutation (e.g. deeper colour, smaller berries).
- Clonal selection vs sélection massale? — Few certified, uniform clones vs cuttings from many old vines to keep diversity.
- Name the Pinot mutation family. — Pinot Noir (original), Pinot Gris, Pinot Blanc, Pinot Meunier — colour/leaf mutations of one grape.
A variety is one plant, copied forever; mutation is how it drifts and how clones are born — which is why choosing the vine you propagate is the first quality decision, made long before the first grape.
