How Important is Quality Management in the Wine Sector?

Winemaking is an ancient art, steeped in deep knowledge of how specific conditions can turn grape or fruit juice into the diverse array of wines we cherish today. Through careful experimentation with yeast-driven fermentation, wineries globally have crafted an extensive range of wine styles.

Vintners combine various grape varieties, yeast strains, and additives in precise, monitored processes to produce wines with unique flavors, aromas, colors, and clarity. Quality control is paramount in this process, guided by global, national, and local regulations that dictate permissible production methods, including the use of additives and processing aids, as well as labeling requirements for wine components.

Overview of Wine Production

Wine is a drink produced by fermenting fruit juice using yeast, with specific processing and additives involved. It has been made since ancient times and holds special significance for Greece, both economically and socially. In the 1960s, Greek wineries adopted modern techniques, leading to a diverse range of high-quality wines.

The winemaking process is generally uniform, with variations based on the desired wine type. Here are the steps involved in grape wine production:

1. Harvesting: Grapes are picked from the vineyards when they reach the desired level of ripeness.
2. Transportation to Winery: The harvested grapes are transported to the winery for processing.
3. Crushing and Destemming: Grapes are crushed to release their juice. They are then destemmed to remove the stems from the grape bunches.
4. Production of Must: The crushed grapes produce a mixture called must, which consists of juice, skins, seeds, and pulp.
5. Juice Separation: For white wines, the juice is typically separated from the skins, seeds, and pulp immediately after crushing. For red wines, the juice, along with the skins, seeds, and pulp, is transferred to fermentation vessels.
6. Sulfur Dioxide Treatment: The separated juice must be treated with sulfur dioxide. This treatment helps prevent oxidation and microbial spoilage.
7. Fermentation: The treated juice or must is transferred to large fermentation vats. Yeast is added to the vats, initiating fermentation. Over a period of 10 to 30 days, yeast converts sugars present in the juice into ethanol (alcohol) and carbon dioxide.
8. Separation from Sediment: After fermentation is complete, the young wine is separated from the sediment (dead yeast cells, grape solids). This process is called racking.
9. Clarification: The wine is clarified to remove any suspended particles. This can be achieved through fining agents or filtration.
10. Aging: The clarified wine is transferred to oak barrels for aging. Aging can last from several months to several years, depending on the desired style and quality of the wine. Oak aging imparts flavors, aromas, and texture to the wine.
11. Blending: Before bottling, wines from different batches or barrels may be blended together. This step helps achieve consistency in flavor and quality.
12. Filtration: The wine may undergo filtration to further clarify it and remove any remaining particles.
13. Bottling: The finished wine is bottled, sealed, and labeled. It is then ready for distribution and consumption.

A similar process will be followed for any fruit wine production as well. The unique characteristics and quality of wine depend on the grape variety, soil quality, location, climate, and the vinification process, including fermentation. Greek vineyards are located on mountain slopes up to 800 meters above sea level or at sea level. Most vineyards have rocky limestone soil, though a significant portion is on fertile plains. Despite covering vast areas, vineyards use minimal land.

Key Determinants for Wine Quality

The quality of wine often stems from a variety of elements, from environmental conditions to cultivation techniques and the intricacies of winemaking. Here are the primary factors that distinguish outstanding wines from the ordinary ones:

Terroir and Climatic Conditions

The concept of terroir, encompassing soil, topography, and climate, profoundly shapes wine quality. Climate and weather patterns play crucial roles in determining grape development, flavor concentration, and the ultimate wine-making potential.

1. Climate: While climates tend to be stable over time, they dictate grape characteristics. Cooler climates yield wines with elevated acidity and subtle sweetness, whereas warmer regions foster riper grapes, resulting in richer, sweeter wines with higher alcohol content. Mismatching grape varieties with unsuitable climates can compromise wine quality.
2. Weather: Unlike climate, which is more predictable, weather fluctuations can swiftly impact wine quality. Ideal vintages depend on grapes receiving precise conditions for optimal growth and flavor.

Sunlight Exposure and Temperature

Grapevines require specific temperature ranges, typically between 77 and 90 degrees F (25 to 32°C), for efficient photosynthesis and grape development.

1. Temperature: In regions where temperatures hover around 60°F, short-cycle grape varieties thrive, while extended-cycle varieties struggle. Excessive heat can expedite grape ripening, potentially hindering flavor and compound maturation.

Cultivation Techniques

Beyond natural factors, a producer’s vineyard management practices influence wine quality. Techniques such as canopy management and pruning play pivotal roles in grape quality and vine health.

1. Canopy Management: Pruning away excess leaves and shoots enhances sunlight exposure, vital for grape maturation.
2. Pruning and Harvesting: Strategic pruning controls yields and maintains vine vigor. The timing and method of harvesting are critical; premature or delayed harvests can lead to imbalanced grapes. While mechanical harvesting offers speed, it lacks the precision of manual picking, which ensures only the finest grapes are selected.

Art of Winemaking

The wine production process is paramount in shaping its final quality. Winemakers employ a sequence of steps, including maceration, fermentation, extraction, and aging, ensuring consistency to maximize grape potential.

1. Winemaking Inputs: Various elements, such as sulfur dioxide, processing enzymes, and oak barrel aging techniques, significantly influence wine quality. Strategic decisions in oxygen management and aging can make the difference between a premium vintage and a mediocre one.

The approach to wine quality as a designed attribute rather than merely controlled has consequential implications for branding. Preventative measures are to be proposed and critical factors and limits should be determined. Studies represent that the CCPs for wine safety are the stages of grape growing, grape harvesting, fermentation, stabilization, aging, and bottling. The most important factors influencing CCPs and CPs should also be understood and controlled as part of the quality management strategy.
