Every late summer, vineyards all over France come alive with activity: it’s the time of the Loire Valley grape harvest.
More than just picking grapes, the harvest is the culmination of a year of meticulous work in the vineyard. The ripeness of the grapes directly determines the quality of the future vintage — whether it’s a white wine, a red wine, or a sparkling Crémant de Loire.
At Domaine de Rocheville, in the heart of the Saumur-Champigny appellation in the Loire Valley, the grape harvest embodies tradition, savoir-faire, and conviviality.
What happens during the grape harvest?
The harvest is a decisive stage in the life of a wine estate. It consists of gathering grapes destined for winemaking — not to be confused with table grapes. For instance, Chenin Blanc, a key Loire grape variety, is used to make white and sparkling wines at Rocheville, while table grapes are grown to be eaten fresh, larger in size, juicier, and with fewer seeds.
Each grape variety is picked at its ideal ripeness to produce high-quality cuvées:
- Structured red wines full of character,
- Fresh and aromatic white wines,
- Elegant sparkling wines,
- And, in some regions, sweet dessert wines from late harvests.
The grape harvest is both an intense and festive period at the estate — a unique balance of hard work, precision, conviviality, and good spirits.e bonne humeur.
When does the grape harvest start?
The harvest date depends on several factors:
- Geography and climate: soil type, altitude, and sun exposure influence ripening speed. Even two neighboring plots can be harvested at different times.
- The winemaker’s choice: for a sparkling wine like Crémant de Loire, grapes are picked slightly underripe to preserve acidity and freshness. By contrast, red grape varieties such as Cabernet Franc require fuller ripeness to craft balanced, full-bodied wines.
In France, the official start of the season is marked by the “ban des vendanges” — the traditional authorization for harvest across the vineyards.
In southern France, harvest can begin in late August, while late harvests may extend well into mid-October.
At Domaine de Rocheville, grape harvest usually begins around mid-September with Chenin Blanc (4 hectares), followed by Cabernet Franc (13 hectares). The harvest lasts about three weeks, allowing each parcel to be picked at its optimal ripeness.4 hectares), puis se poursuivent avec le Cabernet Franc (13 hectares). Elles durent environ trois semaines pour récolter chaque parcelle au moment idéal.
How do you know if grapes are ripe?
Before starting, the winemaker carefully evaluates grape ripeness:
- Sampling: berries are taken from different plots and at various heights on the bunches.
- Sugar levels are measured with a refractometer, an instrument that calculates grape sugar concentration (measured in “Brix”) and predicts the potential alcohol content of the wine.
- Tasting the grapes remains essential: pulp texture, seed color (green or brown), and even the stem’s color (green or red) provide valuable clues.
- Acidity tests are carried out in the lab to ensure balance.
These analyses, combined with weather forecasts, allow the winemaker to decide — sometimes from one day to the next — the perfect moment to begin harvesting.à commencer à tout moment !
Mechanical harvest or hand harvest?
In the Loire Valley vineyards, grapes can be picked either by machine or by hand.
Mechanical grape harvest
In September, you may spot a huge agricultural machine straddling the vines along the Saumur Wine Route: the mechanical grape harvester.
Its principle is simple: the machine shakes the vines, detaching the berries, which are then collected by conveyor belts. This method is fast and cost-effective, particularly on large surfaces. However, it cannot select the best bunches with precision and may damage grapes and stems.
A trained eye easily spots a mechanically harvested plot: grape stems (called rafles in French) often remain hanging on the vine.
Hand grape harvest
Manual harvesting is carried out with secateurs (small pruning shears) by teams of pickers. Though more time-consuming and costly than mechanical harvest, it ensures careful selection, better preservation of the vine, and a higher-quality crop.
Some appellations even require manual harvest by law — for example, Crémant de Loire — to protect the integrity of the bunches. Steep hillside vineyards also demand hand picking.
👉 At Domaine de Rocheville, we have chosen 100% hand harvest across all our 17 hectares. This demanding choice guarantees grape quality, protects our soils and vines, and maintains the human, convivial spirit that defines the harvest season.
Who are the harvest workers?
All year round, a permanent team of four people tends the Rocheville vineyards. During harvest, they are joined by about thirty seasonal grape pickers. Students, retirees, and locals from the region — all come together with enthusiasm, endurance, and a love of teamwork to contribute to the new vintage.
Each has a well-defined role:
- Pickers (cutters) use secateurs to snip bunches, working in pairs across a row. They collect grapes in small buckets.
- Porters (hotteurs) carry heavy baskets (up to 70 kg) on their backs, emptying them into large containers. One porter typically serves six pickers — a physically demanding task with many trips back and forth.
- Sorters complete the process on sorting tables at the winery, removing leaves and debris to ensure flawless grapes for the cuvées.
This teamwork creates the harvest’s unique atmosphere — a blend of solidarity, effort, and shared laughter.
From grape to wine: pressing and vinification
Once picked, grapes are quickly transported to the winery:
- Chenin Blanc (white grape variety) goes directly to the pneumatic press to extract the juice, which will become white and sparkling wines.
- Cabernet Franc (red grape variety) is destemmed, separating the berries from the stems, then carefully hand-sorted before being transferred to stainless steel vats for fermentation.
Each grape variety follows its own precise path to express its full aromatic potential, ensuring the character and quality of each cuvée.
What about late harvest wines?
Late harvest wines are made when grapes are left longer on the vine, reaching natural over-ripeness.
In favorable weather conditions (misty mornings and sunny afternoons), a microscopic fungus called Botrytis cinerea develops on the grapes. Far from harmful, this “noble rot” gently perforates the grape skin, concentrating sugars and aromas.
These botrytized grapes create exceptional sweet white wines with remarkable complexity. The Loire Valley boasts prestigious appellations for such wines: Coteaux du Layon, Quarts de Chaume, Bonnezeaux, and Coteaux de Saumur.
At Rocheville, we occasionally return to late harvest Chenin Blanc when exceptional weather permits, producing limited, unique cuvées — a tribute to the richness of our terroir.
A highlight of the vineyard year
Each vintage begins with this crucial moment when a year’s work transforms into wine. The harvest marks the completion of the vineyard cycle: from winter pruning to summer canopy management, right up to the ripening of the grapes.
It is at once a celebration, a centuries-old tradition, and a decisive technical step. It is the time of early mornings, expert hands selecting each bunch, laughter shared among the rows, and the joyful tension of racing against the weather.
At Domaine de Rocheville, the harvest expresses our passion for winemaking, our respect for terroir and appellation, and our commitment to crafting outstanding wines.
Ultimately, the grape harvest reminds us of the essential truth: behind every bottle lies a collective story, a place, and the promise of emotions to be shared.
