Be sure to remove the vine from pots before planting. If you are using grow tubes , install them after planting, lightly covering the base with soil to exclude herbicide sprays. Do not bury them too deep into the soil as root constriction may occur. In most of the U. To ensure the highest quality vines and a specific cultivar or rootstock , order vines from a reputable nursery [1] in the summer or early fall prior to planting in spring.
For example, you will probably miss out on the best rooted cuttings often termed 1 , and poor quality vines can be too weak to survive.
The nursery should ship the vines at or near your desired timeframe around planting. Once delivered, vines should be planted immediately, if possible, and not stored. Storage of dormant vines leads to desiccation of the roots and buds. This will prohibit the vine from growing optimally and may lead to death. If vines are received before the site is ready for planting e. Do not store vines in water or a refrigerator for long periods of time. Water the heel bed periodically to keep the roots moist but not wet.
Never allow the roots to dry out, as this will lead to poor growth or vine death. Most grapevines are sold as dormant rooted cuttings and are either grafted or own-rooted. Rooted cuttings are graded by nursery industry standards.
A series of warm days can speed up harvest because ripening happens fast in hot weather. Cooler temperatures, on the other hand, can delay harvest. White grapes are harvested earlier than red grapes.
But grapes meant to be used in sparkling wine are harvested earliest of all because a lower sugar content in those grapes is desirable. In fact, Mumm Napa is almost always the first to harvest. In , Mumm kicked off the harvest on July 22 , the earliest start on record.
Pinot Noir , Merlot , and Malbec come in next. Finally, Cabernet Sauvignon and other robust reds like Petite Sirah are harvested. Harvesting usually starts in the wee hours of the morning—perhaps around AM, when the air is cool. Grape juice starts out clear, whether it comes from red wine grapes or white wine grapes. In order for red wine to pick up that beautiful color, the grape skins must remain in contact with the juice.
First, the grapes get sent through a destemmer because the stems contain tannins , and the wine will pick up plenty of tannins from contact with the stems. Then, the grape clusters are crushed to break open the berries.
White wine grapes, which are harvested earlier than red wine grapes, often go right from the field to the press. Sometimes, the grapes are crushed, but certain winemakers choose to skip that step. Instead, they press whole clusters of grapes , skins, stems, seeds, and all, and the juice goes directly into the barrel or the tank to begin the fermentation process.
White grapes are usually pressed quickly to ensure minimal contact between the juice and the skins, stems, and seeds. At this point, the red grapes have been destemmed and crushed, while the white grapes have been pressed. Now, primary fermentation begins, and it can last up to a month. Once yeast converts the sugars from the grapes into alcohol, the red wine grapes are pressed and the juice is pumped into barrels or some other vessel for aging. Since the white wine grapes have already been pressed, what happens next depends on the varietal.
Chardonnay requires malolactic fermentation to develop creamy, buttery flavors, so it will go into barrels for further fermentation. In Sauvignon Blanc, on the other hand, a certain crisp acidity is desirable, so winemakers will work to prevent malolactic fermentation in these grapes. Once primary fermentation is complete, a month or more has gone by since harvest. The vines are preparing for winter, and Napa vineyards are showing off some fall color. The air is cooler and the vibe is mellower.
But the winemakers are still hard at work. After primary fermentation, the wine will be transferred from the fermentation tank to another vessel for aging. Sauvignon Blanc often goes into stainless steel tanks or a concrete egg, while Chardonnay and red wines will go into oak barrels. New French oak? American oak? Hungarian oak? Light toast?
Dark toast? Reused barrels? The question of which oak barrel to use is a subject that many winemakers are passionate about. It all depends on the flavor profile that the winemaker hopes to achieve.
Malolactic fermentation ML takes place during the aging process. This process is what gives Chardonnay its creamy mouthfeel and some of that signature buttery flavor. ML is what helps provide a smooth, rich mouthfeel. The winemaker will prevent the process by filtering the wine to remove the bacteria that cause it. Once ML is complete, winemakers will usually add a very small amount of sulfur to the wine as a preservative to stabilize the wine. So while the wine is aging , the winemaker will continually taste and evaluate the wine.
Slowly, a flavor profile will emerge. According to Bos, Sauvignon Blanc begins to show its flavor profile after about three months. It needs more time for the flavors to develop. At six months, the wine tastes unfinished. Toward the end of the aging process, winemakers will taste the wine frequently to ensure the flavors are just right.
Before bottling, the wine is racked, filtered, or both to remove sediment and clarify the wine. Our bespoke site-finder software is a great starting point in locating the right land.
It is up to you. To engage contractors who manage your vines, pick your grapes and transport them to an established producer, with whom you have contracted to sell your harvest, requires very little of your own equipment. A vineyard tractor and topper is probably all you will need. However, if you wish to undertake all of the husbandry, winemaking, bottling, cellarage and marketing yourself, you will need all of the vineyard equipment, a winery, cellarage, staff and offices.
This level of investment requires diligent planning, budgeting and significant finance. It also requires patience, as it will take four years for still wine to eight years for sparkling from planting before your wine is ready for sale. You should then expect an average yield of about 3 tonnes per acre from which you will produce roughly bottles of your very own wine.
