    Alcohol in Wine

    The amount of alcohol in wine is influenced by the fermentation process and the sweetness of the grapes. More fermentation leads to higher alcohol content. Sweeter grapes naturally produce higher alcohol levels. The process of Chaptalization, adding sugar to increase alcohol, is allowed in some countries.

    Chaptalization

    Detect Wine Alcohol

    You can detect alcohol in wine by its burning sensation in your throat. The intensity of the burning feeling is related to the alcohol content. Wine with higher alcohol content will have larger and slower-moving tears (or 'legs') on the side of the glass.

    What are tannins?

    Tannins are compounds in wine that give it a dry, astringent sensation. They're found in grape skins, seeds, and even oak barrels.

    What effect do tannins have on wine?

    Tannins contribute to a wine's structure, mouthfeel, and aging potential. They add a dry, often bitter, sensation. High tannins can make a wine feel harsh, especially when young, but they soften with age.

    How can you detect tannins in wine?

    You can detect tannins by the sensation they create in your mouth – a drying, astringent feeling. This is similar to the feeling you get when you sip on tea.

    What is acidity in wine?

    Acidity refers to the sourness of a wine. It's measured by pH, with higher pH indicating lower acidity.

    Signup and view all the flashcards

    What's the role of acidity in wine?

    Acidity gives wine freshness and vitality, helps balance sweetness, and keeps the wine stable. It also slows down the oxidation process, which helps the wine age gracefully.

    How does acidity impact wine taste?

    High acidity makes a wine taste sharper, crisper, and lighter-bodied; lower acidity gives a fuller, rounder, and sweeter taste.

    What roles do alcohol and acidity play in wine?

    Both alcohol and acidity are crucial components of wine, impacting its flavor, longevity, and overall sensory experience. Alcohol provides the 'warming sensation' and also helps preserve the wine, while acidity adds a refreshing touch.

    Signup and view all the flashcards

    What is the connection between acidity and tannins?

    While there isn't a direct cause-and-effect relationship, wines with higher acidity often have lower tannins, and vice versa. This is because the types of grapes grown and the winemaking process influence both attributes.

    Study Notes

    Wine Production and Characteristics

    • Wine is an alcoholic beverage made from fermented grapes. While any fruit can be used, wine grapes are the most common. Cranberry juice can also be called wine. Wine-making requires specific wine grapes, not table grapes.
    • Italy boasts over 600 grape varieties, spanning its regions.
    • Ideal wine grapes are smaller, seeded, and have thick skins (high pectin content).
    • Grapes can be carefully preserved for many years without chemicals.
    • Most wine grapes are cultivars of the Vitis Vinifera species.
    • Vitis Vinifera vines produce about 2-5 kg of grapes. Vine characteristics include being woody, annual crop producers, and affected by climate influencing sweetness.
    • Wine quality and price relate to the care and time involved in its production.
    • Examples of high-quality wine: Barolo
    • Vintage refers to the year the grapes were harvested, while non-vintage wine blends grapes from different years.

    Wine Types

    • Wine styles include sparkling (with bubbles), still (dry, no bubbles - in white, rosé, red, and garnet variants), sweet (late harvest), and fortified (dessert wine). Examples include Madeira and Vermouth (aromatized).

    • Single varietal wines use mostly or entirely one grape type, like Merlot.

    • Wine blends combine different varietal wines.

    • Field or blended wines utilize multiple grape varieties harvested and vinified together.

    Wine Components

    • Wine has identifiable components: body (texture), sweetness, tannins, acidity, and alcohol content.
    • Winemakers can use equipment to manage wine temperature and characteristics.
