Introduction to Wine Processing
Wine is a fermented alcoholic beverage traditionally made from grapes, but it can also be produced using various fruits. The alcohol content typically ranges from 5% to 13%. A symbol of culture and tradition across the globe, wine is cherished for its aroma, flavor, and texture, and is commonly paired with meals. In the modern food and beverage industry, wine processing is a growing segment supported by advancements in food technology consulting and food manufacturing consultancy.
History and Origin of Wine
Wine production is believed to have begun more than 8,000 years ago in ancient civilizations like Mesopotamia, Egypt, and China. The earliest modern evidence of winemaking dates back to 6000 BC in Georgia, where grape cultivation began as a dedicated process.
Types and Classification of Wine
1. Based on Alcohol Content
- Natural Wine: 9–14% alcohol (dry, sweet table wine, Muscat, Burgundy, Champagne)
- Dessert & Appetizer Wine: 15–21% alcohol (Port, Cherry, Vermouth)
2. Based on Sparkling Effect
- Still Wine: No carbonation
- Sparkling Wine: Contains CO₂ (natural/injected)
- Fortified Wine (Vermouth): Wine with added alcohol
3. Based on Colour
- Red Wine: From black grapes
- White Wine: From white or yellow grapes
- Rosé Wine: Short maceration or direct pressing
4. Based on Base Material
- Fruit Wine: Apple, mango, banana, jackfruit, etc.
- Berry Wine: Cherry, blueberry, etc.
- Plant Wine: Rhubarb, rose petals, parsnips
- Raisin Wine: Made from dried grapes
- Multi-sort Wine: Blend of different grapes and materials
Global & Indian Wine Market Overview
As per the OIV 2023 report, global wine production was 258 mhl, with consumption dropping to 232 mhl due to the energy crisis and logistics issues.
In India, the All-India Wine Producers Association (AIWPA) reports the crushing of 20,000 MT grapes to produce 14 mhl wine annually, with Maharashtra contributing ~90%. India’s wine industry is witnessing increased demand, leading to a rise in import dependency.
Key Factors Affecting Wine Quality
1. Grape Quality
- Climate-sensitive:
- Cold climates → high acidity
- Warm climates → higher sugar and alcohol
- Ripeness and harvesting time impact flavor and yield
2. Minimal Processing
- Sorting, washing, stemming to ensure hygiene and consistency
3. Winemaking Techniques
- Fermentation, filtration, fining, aging – all crucial in determining quality
Wine Manufacturing Process – Step by Step
➤ Must Preparation
Grapes are mechanically crushed to extract juice and aroma compounds. The must is prepared depending on the type of wine.
➤ Fermentation
- Yeast: Saccharomyces cerevisiae var. ellipsoideus (2–5%)
- Fermentation conditions:
- Red wine: Anaerobic, 24–27°C for 3–6 days
- White wine: Anaerobic, 1–20°C for 4–12 days
- Daily mixing enhances yeast activity and pigment extraction
➤ Clarification & Aging
- Filtration removes solids
- Racking separates sediments
- Fining agents (e.g., bentonite, egg white) improve clarity
- Wine is blended for consistency
- Bottling and pasteurization: 82–85°C for 2 minutes
- Aging under controlled humidity and temperature refines flavor
Quality Control in Wine Manufacturing
Quality assurance is critical in food manufacturing consulting. It includes:
- Monitoring fermentation parameters (pH, sugar, acidity)
- Microbial testing to prevent spoilage
- Sensory evaluation for aroma, body, and taste These practices ensure consistent, safe, and authentic wine products, a key aspect in food consultancy services for beverage manufacturers.
Health Benefits of Wine (Moderate Consumption)
- Rich in antioxidants
- May help reduce inflammation
- Exhibits anti-carcinogenic and antimicrobial properties
- Supports cardiovascular health (subject to medical guidance)
