Merlot is one of the most popular red wine varieties worldwide, cherished for its smooth texture, fruity flavors, and accessibility. Known for being less tannic than other red wines like Cabernet Sauvignon, Merlot has a soft and velvety mouthfeel that appeals to many wine drinkers, from novices to connoisseurs. The making of Merlot wine is a meticulous process that begins in the vineyard and continues in the winery. From vine to bottle, Merlot is carefully crafted to ensure the resulting wine is flavorful, balanced, and memorable. This article will take you step-by-step through the entire process of how Merlot wine is made, from the growing of the grapes to the final stages of aging and bottling.
The process of making Merlot begins in the vineyard. Merlot grapes thrive in a variety of climates, but they particularly excel in regions with a temperate climate, such as Bordeaux in France, California, and Chile. The key to making great Merlot is ensuring that the grapes are grown under optimal conditions, which include good sunlight, proper soil composition, and adequate drainage. Merlot vines are typically pruned to control their growth and ensure the right balance between fruit production and vine health. Growers must constantly monitor the vines for pests, diseases, and environmental stressors, as these can negatively impact the quality of the grapes. Harvesting time is critical, as the grapes must reach the perfect level of ripeness for optimal flavor development.
Harvesting Merlot Grapes
The first major step in the process of making Merlot wine is harvesting the grapes. Timing is crucial in this phase, as picking too early or too late can drastically affect the final product. Merlot grapes are typically harvested between late summer and early fall, depending on the climate and growing conditions of the region. Grapes are harvested either by hand or with mechanical harvesters. Hand-harvesting is often preferred for high-quality wines because it allows for more selective picking, ensuring that only the ripest, healthiest grapes are used in the winemaking process.
Once the grapes are picked, they are carefully transported to the winery, where they undergo a sorting process. This is a critical step to ensure that any damaged or underripe grapes, as well as leaves and stems, are removed. The goal is to retain only the best fruit for fermentation, as the quality of the grapes will have a direct impact on the wine’s flavor and aroma. In some cases, the grapes are also chilled during transportation to preserve their freshness and prevent premature fermentation.
Crushing and Destemming the Grapes
After sorting, the Merlot grapes are crushed and destemmed. This process breaks the skins of the grapes and releases the juice, which will eventually become the wine. Destemming removes the stems from the fruit, as they can introduce bitterness and undesirable flavors into the wine. Crushing can be done by hand or with mechanical crushers, depending on the winemaker’s preference and the scale of production. The goal is to extract as much juice as possible while minimizing the release of harsh tannins, which is important for Merlot’s soft, approachable style.
In some winemaking traditions, such as those in Bordeaux, the crushed grapes (now referred to as “must”) are left to ferment with the skins, as this process contributes to the wine’s color, texture, and tannin structure. However, the amount of skin contact varies depending on the style of Merlot being made. In modern winemaking, some producers may use a process called “cold soaking” to allow the grapes to sit in a cold environment before fermentation. This helps to extract more color and fruit flavors while minimizing harsh tannins.

Fermentation Process
Once the grapes have been crushed and destemmed, they are transferred to fermentation vessels, where the magic of turning grape juice into wine takes place. Fermentation is initiated by the addition of yeast, either naturally occurring or commercial, which converts the sugars in the grape juice into alcohol and carbon dioxide. The fermentation process typically lasts between one and two weeks, during which the temperature is carefully controlled to ensure the optimal fermentation conditions.
During fermentation, the must is regularly stirred to ensure that the juice is evenly exposed to the skins, which allows for the extraction of color, flavor, and tannins. This process is known as “punching down” and involves breaking up the cap of skins and pulp that forms at the top of the fermentation vessel. In some cases, winemakers may use mechanical pumps to perform a process called “pumping over,” which helps to circulate the juice and skins, further enhancing flavor extraction.
Pressing the Wine
After fermentation is complete, the next step in making Merlot is pressing the wine. This is where the skins, pulp, and remaining juice are separated. The purpose of pressing is to extract anyremaining juice from the solids. In some cases, a light pressing is done to ensure that the wine remains soft and smooth, while in other cases, a more intense pressing may occur to extract more tannins and structure, especially for blends with other grape varieties.
The resulting liquid is then transferred to a fermentation vessel, where it is allowed to settle for several days to clarify. The winemaker may use a process called “racking” to remove any sediment from the wine, ensuring a cleaner and more refined final product. At this point, the Merlot wine is still relatively young and requires aging to develop its full range of flavors.
Aging Merlot Wine
Aging is a crucial stage in the production of Merlot. It is during this time that the wine develops complexity, depth, and balance. Merlot wines can be aged in a variety of vessels, including stainless steel tanks, concrete vats, and oak barrels. The choice of aging vessel can have a significant impact on the wine’s flavor profile. Stainless steel tanks preserve the fresh, fruity character of Merlot, while oak barrels add structure, tannins, and subtle notes of vanilla, spice, and toasted wood.
Merlot wines can be aged anywhere from a few months to several years, depending on the style of wine and the preferences of the winemaker. In Bordeaux, Merlot is often blended with Cabernet Sauvignon and Cabernet Franc, and the wine may undergo extended aging to soften the tannins and allow the different grape varieties to harmonize. In other regions, Merlot is often made as a single varietal wine, which may be aged for shorter periods to maintain its fresh and approachable character.
Blending and Bottling
Once the Merlot has aged to the winemaker’s satisfaction, it may be blended with other wines to create a more complex or balanced final product. For example, in Bordeaux, Merlot is often blended with Cabernet Sauvignon or Cabernet Franc to add structure and depth. The winemaker will carefully taste and evaluate the wine to ensure the right balance of flavors, tannins, and acidity.
After blending, the wine is filtered to remove any remaining solids, and it is often fined to improve its clarity and stability. Fining involves adding a substance, such as egg whites or bentonite clay, to the wine to help clarify it by binding with and removing undesirable particles. Once the wine is clarified, it is ready for bottling.
Conclusion
The production of Merlot is an intricate and delicate process that involves many steps, each of which plays a role in shaping the final wine. From the careful selection of grapevines and harvest timing to the fermentation, aging, and bottling processes, every decision a winemaker makes influences the style, flavor, and quality of the Merlot wine. Whether produced as a single varietal wine or as part of a blend, Merlot remains one of the most versatile and popular wines in the world, beloved for its approachable character and rich, smooth flavors.
For anyone interested in the world of winemaking, understanding the steps involved in producing Merlot offers valuable insights into the artistry and science of wine production. It is a craft that requires patience, skill, and attention to detail, but the result is a wine that is enjoyed by millions of people around the globe.
