Grape Variety Selection: How to Decide Your Vineyard's Business Model

COA Insights, Chapter 2

Key question: which variety is the right fit for your project, not which variety is the best in absolute terms?

In Chapter 1 of this series, we introduced the five terroir elements, based on the scientific frameworks of researcher Claudio Pastenes, professor at the University of Chile: climate, soil, water, plant, and human factor. We explained there that the plant, the fourth element, actually covers three distinct decisions: variety, clone, and rootstock.

This chapter dives into the first of these three decisions: choosing the variety. It's probably the most visible decision in the whole project — it's the one that ends up on the label — but it's also one of the most poorly evaluated, because it tends to be treated as a matter of personal taste or regional tradition, when in practice it's a business-model decision.

The question we hear most from clients is "what's the best variety to plant?" That question is poorly framed, and answering it directly would do a disservice. There's no such thing as the best variety. There's the right variety: right for the climate of the land, for the intended wine style, for the available market, and for the productivity that sustains the business's profitability.

1. Climate compatibility

The first constraint is biological, not commercial. Each variety has its own vegetative cycle and a minimum heat requirement to ripen properly. Long-cycle varieties, like Cabernet Sauvignon, need to accumulate a high number of warm days during the cycle; planted in colder or short-season climates, they risk never reaching full phenolic maturity, resulting in green tannins and unbalanced acidity. Short-cycle varieties tend to adapt better to regions with harsh winters or shorter summers. This compatibility connects directly to the climate analysis from Chapter 1: the same plot of land, assessed through the lens of macroclimate and mesoclimate, can be excellent for one variety and unviable for another.

In regions with mild winters, like much of Brazil, there's a technique that works around this limitation: double pruning. It allows grapes to be produced even without the Mediterranean winter chill that many European varieties naturally require, but it depends on careful management of other variables, such as pruning dates and the correct use of Dormex, to induce controlled budbreak. It's not an automatic solution: without that fine-tuned management, the system doesn't replace the variety's natural climate requirement.

2. Wine style

The variety also largely defines the repertoire of wine styles the project can offer. Tannic structure, aromatic profile, aging potential, and body are, to a significant extent, pre-determined by the genetics of the chosen variety, even before any winery decision is made. A project aiming to produce a full-bodied, long-aging red, but that plants a light, fruity-profile variety, creates a mismatch between commercial expectation and possible outcome. The variety sets the wine's stylistic ceiling, just as the terroir sets its quality ceiling.

3. Market and commercial positioning

This is the least-discussed dimension at planting time, and one of the most decisive for business viability: who's going to buy this wine, and at what price? Established international varieties, like Cabernet Sauvignon, Chardonnay, or Malbec, carry immediate consumer recognition and open doors in established sales channels, but they compete in more crowded, more price-sensitive markets. Lesser-known or native varieties can support a differentiation positioning and reach higher-value-added niches, provided there's a commercial strategy and brand narrative capable of justifying that positioning to the consumer. There's no universally correct answer: there's alignment, or misalignment, between the chosen variety and the project's commercial plan.

It's also worth remembering that the target market doesn't depend only on the variety's brand recognition: the climate, food habits, and local consumption patterns of the place where the wine will be sold also strongly influence which wine style sells best. A market with a hot climate and spicier or richer cuisine, for example, may call for a different wine profile than a market with a cold climate and lighter cuisine.

4. Productivity and profitability

Each variety has its own productivity profile, usually measured in kilos of grapes per hectare or liters of wine per hectare, and that number feeds directly into the project's financial equation. More productive varieties can support a business model based on volume and more accessible pricing. Low natural-productivity varieties, or ones that require yield reduction (fewer clusters per plant) to reach quality, support business models based on added value and premium pricing. A project that chooses a low-productivity variety without planning, from the start, a compatible price positioning is undermining its own economic viability before the first harvest.

An additional point comes into play when the double-pruning system is used: in our field experience at COA, double pruning tends not to reach the same kilos per hectare as the traditional single-cycle-per-year method, and the vineyard's annual maintenance cost tends to be higher, since it involves two production cycles in the same year. Lower productivity per cycle and higher maintenance cost need to factor into the profitability math of any project evaluating double pruning as a strategy.

A note on clones

Within each variety there's yet another layer of decision: the clone. Different clones of the same variety can show meaningful variation in productivity, cluster size, disease resistance, and even aromatic profile. This is a fine-grained choice that usually comes after the variety is defined, and one we'll cover in more depth in future chapters of the series, along with rootstock.

What this means in practice

Consider two neighboring projects, on the same plot with favorable terroir, assessed as recommended in Chapter 1. The first chooses the variety by crossing the four criteria above: climate compatibility, intended wine style, target market, and the productivity needed to sustain the business model. The second chooses based on whichever variety is trending, or whichever the most admired neighbor in the region also plants.

Years later, the first project harvests grapes aligned with the planned wine style, with a market already mapped out to receive it and productivity compatible with the projected margin. The second may harvest technically healthy grapes, but discovers, when it's time to sell, that the wine doesn't find the right buyer, or that the volume produced doesn't support the price the business needed to charge.

This chapter's central message is direct: choosing the variety is choosing a business model.

Why COA treats variety choice as a strategic decision

A poorly chosen variety isn't a mistake you fix later with more investment in the winery, the brand, or sales channels. It's a structural limitation: just like the land, the variety stays with the vineyard for decades.

That's why, at COA, variety choice is never treated in isolation. It's always cross-checked against the already-assessed terroir (Chapter 1) and the client's business plan, to make sure the agronomic decision and the commercial decision move forward together from the start.

This is the second chapter of the COA Insights series: the decisions that turn a vineyard into a sustainable business. In the next chapter, we cover the project's third major decision: rootstock, the invisible choice that shapes decades of production.

If you're evaluating which variety to plant, or you already have a vineyard in place and want to review the alignment between variety and business model, now is the right time to talk: COA's Strategic Assessment Session.
