Lecture 20: Wine Complexity and Quality
Many definitions of wine “Quality” center on “Complexity” How does one define “harmonious”?
Harmonious Complexity: The flavors and aromas present meld well, so well that they become difficult to distinguish.
Wine Flavor/Aroma Families • Food: Plant • Food: Non-Plant • Non-Food
Vegetable Herbal Floral Spice Processed Plant (olive,tea,coffee,) Fermented Plant (pickled,vinegar) Tropical Fruit Citrus Fruit Non-Berry Tree Fruit Red Fruit Purple Fruit Dried Fruit Nut FOOD: PLANT
Meat Beef Salami Bologna Dairy Cheese Cream Butter Butterscotch Sea Food Yeasty Fungal Soy Mushroom Other Cotton Candy Rotten Egg Chocolate Caramel FOOD: NON-PLANT
Vegetation Wood Paper/Cardboard Solvent Soil/Musty Animal/Barnyard Metallic Pharmaceutical Complex Sulfur (burnt match,rubber) Complex Ester (perfume, soap, plastic) NON-FOOD
Harmonious Complexity vs. Complexity Cherries, Strawberries, Butter, Citrus, Paper, Solvent and Wet Dog: complex, but is it harmonious?
Source of Flavor/Aroma Compounds • Grape • Microorganisms • Aging (Time) • Addition: Oak, Fining, Aeration • Removal: Fining, Aeration
Factors Affecting Wine Characters • Volatilization • Chemical Reactivity • Chemical Stability • Metabolism • Downstream Processing: fining; oxygen • Sensitivity to Dilution
Most wine characters are derived from or are metabolites of compounds present originally in the grape. Grape composition is critical in the production of a quality wine.
Wine production processes have a strong impact on the metabolites produced and characters remaining in the wine at the time of bottling. Winemaking practices are critical for production of a quality wine.
French vs. American Breeding vs. Personality Harmony vs. Complexity
Personality: Inherent Genetic Factors Influenced by Environment
Breeding: Inherent Genetic Factors Influenced by Environment Is Only the Beginning . . .
This concludes the Wine Production course. Life is too short to make or drink bad wine!
