The Five Stages of Winemaking

Harvesting and sorting of wine grapes

The wine making process progresses through five fundamental stages of making wine:

  1. Harvesting
  2. Crushing and pressing
  3. Fermentation
  4. Clarification
  5. Aging and bottling

Each stage is a critical step in the journey from grape to glass, and understanding the intricacies of these stages provides a deeper appreciation of the art and science behind each bottle of wine.

The sugar level in grapes, which determines the final alcohol content and is an indirect index of grape maturity, is assessed using Brix, a measure of the soluble solids in grape juice, including sugar, salts, acids, and tannins. Following fermentation, the processes for wine clarification and stabilization are instrumental in ensuring the wine’s clarity and stability. The carbon dioxide produced during fermentation is released into the atmosphere, and prior to bottling, the wine undergoes filtration to ensure microbial stabilization.

Harvesting and Destemming

Harvesting, marking the commencement of the wine production process, involves the picking of grapes. This can be done either mechanically or manually, each method having distinct implications for the winemaking process. Mechanical harvesting offers the advantage of quickly covering a large area with minimal manpower, however, it may also result in the inclusion of undesirable materials, which can have a negative impact on the quality of the wine.

The most suitable time for grape harvesting is determined by various factors such as:

  • weather conditions
  • pests
  • vineyard practices
  • growing degree days

These factors collectively influence the sugar, acid, and flavor profiles of the grapes, setting the foundation for the wine’s eventual profile.

Crushing and Fermentation

Fermentation process in winemaking

Following harvesting, the next phase, crushing, necessitates gently squeezing the berries and breaking the skins to trigger the release of the berries’ contents. Enhancing the color, texture, flavor, and body of red wines, the process of crushing grapes plays a significant role in the overall winemaking process.

During fermentation, the ‘cap’, a layer of grape skins and other solids, floats to the surface of the fermentation tank, contributing to the color and flavor profile of the wine. The fermentation process transforms the grape’s natural sugars into alcohol, creating the wine’s unique character and structure.

Malolactic Fermentation

Malolactic fermentation involves the metabolic process of lactic acid bacteria converting malic acid into lactic acid and carbon dioxide. This conversion leads to a softening of the wine’s taste, enhancing its palatability.

The process of malolactic fermentation has the effect of smoothing the taste of wine by transforming the harsh malic acid into a milder lactic acid, thereby decreasing the overall acidity of the wine. It is essential to monitor the pH levels during malolactic fermentation, maintaining them below a pH of 3.55 for white wines and 3.80 for red wines.

Aging and Maturation

Aging and maturation, vital stages in winemaking, significantly influence the wine’s flavor, aroma, and overall quality. The aging process can occur in a variety of materials, including:

  • Stainless steel tanks
  • Oak barrels
  • Glass
  • Plastic
  • Amphorae or concrete eggs

Each material contributes distinctively to the wine’s development.

One of the characteristics that distinguishes wine from many other beverages is its ability to evolve in flavor over time. The typical maturation period for red wines ranges from 8 to 12 years, whereas white wines are best consumed within 2 to 3 years of bottling. This process creates a depth and complexity of flavors that can make an already excellent wine truly exceptional.

Bottling and Preservation

Bottling and sealing of wine

Bottling and preservation mark the concluding stage in the winemaking process. During this phase, the following steps are taken:

  1. The bottles are washed with sterilized and microfiltered water.
  2. The corks and corker are prepared.
  3. The bottles are filled with the clear and stable wine.

In addition to bottling, the preservation of wine is crucial to maintaining its quality. Fining agents, such as gelatin, are utilized to eliminate tannins, diminish astringency, and eradicate microscopic particles that have the potential to cause cloudiness in the wines, thereby contributing to its preservation. The choice of closure for a wine bottle is also critical, with options ranging from traditional corks to synthetic corks and screwcaps.

Winemaking Techniques for Unique Flavors

In addition to the fundamental stages of winemaking, winemakers employ specialized techniques to yield wines with distinctive flavors and aromas. These techniques, including carbonic maceration, sur lie aging, and barrel fermentation, allow winemakers to express their creativity and craft wines with distinct profiles.

Each of these techniques brings its unique influence to the wine. Here are some examples:

  • Carbonic maceration is known for yielding vibrant, fruit-driven red wines with reduced tannins, resulting in a softer and fruitier flavor profile.
  • Sur lie aging contributes to the improvement of the wine’s mouthfeel, body, and aromatic complexity, introducing ‘yeasty’ or ‘nutty’ flavors, especially in white wines.
  • Barrel fermentation contributes to the introduction of flavor compounds such as vanilla, clove, smoke, and coconut, thereby producing a more rounded and creamier flavor and texture in the wine.

Carbonic Maceration

Carbonic maceration is a winemaking technique that entails the placement of whole, intact grape clusters into a sealed vessel filled with carbon dioxide. This method is utilized to create red wines that are characterized by their fresh, fruity flavor profile and low tannin levels.

This technique imparts a fruitier and softer taste to the wine, characterized by vibrant fruit flavors such as cherry, raspberry, and strawberry. Additionally, it generates esters that contribute fruity notes like banana, bubblegum, and strawberry, along with floral and herbal undertones.

The practice of carbonic maceration is notably employed in Beaujolais, located in the Burgundy region of France.

Sur Lie Aging

Sur Lie Aging is a winemaking process that allows the completed wine to remain in contact with the lees, which are the residual yeast cells. This process enhances the extraction of additional flavors and can introduce complexity with notes of:

  • bread
  • grains
  • nuts
  • yeast

Sur Lie Aging is predominantly employed in white wines, particularly in the Muscadet region of the Loire Valley, the Burgundy region, and in Champagne production. The technique affects the mouthfeel and texture, imparting a creamy characteristic to the wine and contributing to a more integrated flavor profile.

Barrel Fermentation

The technique of barrel fermentation brings an added layer of complexity to the winemaking process. The process involves fermenting a portion of the wine in oak barrels, while the remainder may undergo fermentation in stainless steel or concrete tanks. This method contributes to the development of smooth tannins and the creation of a fuller, more velvety texture in the wine.

Barrel fermentation facilitates the gradual introduction of oxygen, resulting in a smoother and less astringent taste in the wine. Red wines and Chardonnay are the varieties that experience the greatest advantages from barrel fermentation, their profiles enhanced by the slow introduction of flavors from the barrel.

Wine Regions and Terroir
