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.
