Key ideas in Wine: Tasting, Terroir, and Trade
- Personal preference ('I like this') describes the taster, while quality assessment ('this is well-balanced') describes the wine
- A wine can be impeccably made and high quality even if its style does not match your personal palate
- Professional tasting evaluates objective structure—balance, length, intensity, and complexity—independent of personal preference
- Thin-skinned grapes like Pinot Noir yield paler, translucent red wines compared to thick-skinned grapes like Cabernet Sauvignon
- Red wines lose pigmentation and develop garnet or tawny edges as they age
- White wines gain color with oxygen exposure and barrel aging, shifting from pale lemon toward gold or amber
- Primary aromas derive directly from the grape variety and fresh fruit fermentation (fruits, florals, herbs)
- Secondary aromas stem from post-fermentation winemaking choices, such as oak barrels (vanilla, cedar, toast)
- Tertiary aromas develop through deliberate aging and bottle maturation (leather, dried leaves, earth, forest floor)
- Drawing in air (slurping or gurgling) volatilizes aromatic compounds up into the nasal cavity via the retro-nasal passage
- Aerating and moving the wine spreads it across the entire tongue and gums, making mouth-drying tannins and mouth-watering acidity distinct and measurable
- Length of finish measures how long desirable, complex flavors linger after swallowing or spitting
- Simple, commercial wines often show upfront fruit punch but vanish almost instantly (short finish)
- A long, persistent finish reflecting balance and multi-layered complexity is one of the clearest hallmarks of premium wine
- Acidity stimulates saliva flow along the sides of the tongue and mouth
- Wines with high acidity taste vibrant and refreshing, while low-acid wines can taste flat or flabby

Here's what playing it feels like
A real question from this course. Take your best guess.
You sip an intensely tart, high-acid dry Riesling and realize you personally dislike sour flavors. What does this mean for the wine?
