Winemaking: one production run a year and no second attempt

Harvest compresses a year of decisions into a few weeks

Picking dates are dictated by ripeness, and several blocks often reach their moment together, so intake, pressing and tank allocation happen under time pressure with no option to defer. Presses, chillers and pumps must be serviced beforehand because a failure during harvest cannot wait for a spare part. Seasonal labour has to be recruited, housed in some regions, and trained fast. Any bottleneck in receiving fruit shows up as grapes waiting in the sun, which degrades quality irreversibly. This is why capacity planning in a winery is really about the peak fortnight rather than the annual total.

Owning vineyards or buying fruit are different businesses

Estate fruit gives control over viticulture, harvest timing and the story on the label, at the cost of substantial land capital and exposure to frost, hail, drought and disease on specific parcels. Buying grapes or bulk wine converts that into a purchasing relationship, spreads weather risk across sites and frees capital, but leaves the winemaker negotiating in a market that tightens exactly when a poor season hits everyone. Long-term grower contracts specifying yield limits, picking parameters and price mechanisms sit between the two, and their quality largely determines whether a merchant winery can hold a consistent style.

Tanks, barrels and the cash they hold

Fermentation and storage vessels are sized for the vintage and stand partly idle afterwards, which looks inefficient on paper but is unavoidable. Oak barrels are a consumable with a limited useful life whose flavour contribution declines with each use, so a barrel programme is an annual purchasing commitment as well as a stylistic choice. Wine ageing before release, whether in wood, tank or bottle, holds working capital in a way that resembles distilling on a shorter timescale. A winery expanding volume must therefore fund vessels, wood and stock simultaneously, which is where many growth plans stall.

Rules that constrain what you may write on the bottle

Geographical designations bring rules on permitted varieties, yields, growing area and often production methods, enforced through registration and inspection. They add value at market and remove flexibility in the cellar: a blend that would taste better may not be allowed under the designation, and exceeding a yield limit can force a whole parcel out of the classification. Export adds another layer, because labelling, additive and certification requirements differ between destination markets. Practical winemaking businesses treat these constraints as design parameters set before harvest, not as paperwork completed at bottling. Where the rules cost more than the designation returns, dropping to a broader category is a legitimate commercial choice rather than an admission of failure.

Where wineries actually make and lose money

Bulk wine sold to bottlers earns a commodity return that tracks global supply, and a large vintage anywhere in the world can undermine pricing everywhere. Bottled wine sold under a recognised label earns considerably more but demands brand investment, distribution agreements and often years of consistent quality to build. Dry goods, meaning glass, closures, labels and cartons, form a surprisingly large share of the cost of an inexpensive bottle, so pricing that ignores packaging inflation misleads. The recurring newcomer error is buying romance in the form of vineyard land while under-funding the cellar, the stock and the route to market.

Frequently asked questions

How much does vintage variation really affect a wine business?

It affects both volume and mix, which is more disruptive than it sounds. A short harvest reduces the wine available for every tier at once, forcing decisions about which labels to cut, while a large harvest can strain tank capacity and depress bulk prices. Quality variation changes the blend structure and may push fruit intended for a premium label into a lower tier. Businesses handle it with multi-region sourcing, reserve stock held between vintages, and contracts that flex quantity rather than assuming a fixed intake.

Is it better to sell wine in bulk or to bottle under your own label?

Bulk sales convert a vintage into cash quickly, require no packaging investment and suit wineries whose strength lies in growing and fermenting. Bottling under an owned label captures far more of the final price but ties up stock, needs a sales organisation and takes years to establish. Many wineries do both, using bulk to clear surplus volume and protect cash flow while building a smaller bottled range. The danger is drifting into permanent bulk supply and never developing a customer of your own.

What limits how quickly a winery can grow production?

Fruit supply and vessel capacity, and both move slowly. New vineyard plantings take years to produce usable crops, and contracting additional growers competes with other buyers in the same region. Tanks, presses and barrels have to be installed before a harvest, not during it, and the building itself may constrain layout. Add the working capital held in maturing and unsold stock and growth becomes a multi-year commitment rather than a decision made in a single season.
