Viscosity, Dissolved Gas, Texture, Temperature, Astringency, Heat (from alcohol), Sulfur Dioxide
Term
Viscosity
Definition
aka 'body' or 'weight' of wine; how much it 'fills the mouth'; caused by high sugar, alcohol, or extract levels
Term
Astringency
Definition
caused by high tannin levels (young reds); tannins react with proteins in saliva & surface of the cells to make a puckery rough sensation as parts of the mouth chafe
Term
Heat (from alcohol)

high alcohol content creates a hot tactile sensation

Cardinal Rules of Wine Tasting Set-Up
Definition
1) no perfume/aftershaves
2) well lit room, no extraneous odors
3) white placemats
4) tulip-shaped glasses
5) clear and unfaceted glasses
6) glasses not washed in scented detergent
7) store glasses in non-odorous environment
Term

45-50 degrees F (7-10 degree C)
Term
Temperature for Service of Dry Whites and Roses
Definition
50-60 degrees F (10-15 degrees C)

Tasting Order

1. Dry before sweet
2. Light-bodied (low viscosity) before full-bodied (high viscosity)
3) Modest before fine
*Generally white before red
*Generally young before old, but if old is delicate, drink first
Term
Evaluating a flight of wines
Definition
evaluate color & appearance of wines, quick smell, then smell in detail
Term
Judge wine on
Definition
Appearance/clarity, color, odor, taste/mouth feel/flavor
Term
To Judge Appearance/Clarity
Definition
hold wine up to bright light, inspect for particulate matter & cloudiness; legs/tears are a function of wine's alcohol/sugar content; evaluate sparkling wine by amount of mousse and consistency/size of bubble stream; Cuvee of base wines is benchmark of quality
Term
To Evaluate Color
Definition
hold wineglass up against a light, tip forward and evaluate the color, hue and pigment density. Deeply pigmented wines indicate high levels of extract and flavor; color linked to pH.
Term
High Acid White/Red
Definition
Green/Ruby hue
Term
Low Acid White/Red
Definition
Gold/Blue hue
Term
Odor Evaluation
Definition
Sniff, Swirl, Sniff; Check for Off-odors, Aroma (scents of grape varieties), Bouquet (scents of wine making, barreling, and bottle aging)
Term
Taste (Evaluation)
Definition
1. Sip and roll
2. Warm wine in mouth
3. Slirp
4. Evaluate structural components (acidity, sweetness, astringency, mouth feel, body/weight, heat, CO2)
5. Spit
6. Savor
Term
# of Glasses of Wine in a Bottle
Definition
5
Term
Best ways to aerate wine
Definition
Decant or pour glasses a course before to be drank
Term
Sediment
Definition
Older wines can have sediment, decant wine carefully to remove wine from sediment or pour gently and use a napkin to control drips
Term
Decanting Young Robust Reds
Definition
softens and mellows tannins; allows fruit flavors to emerge
Term
Decanting Complex Wines with Moderate Aging (Nebbiolo-based and Cabernet-based)
Definition
If serving one that is only a few years old, decanting will allow tannins to soften and aromas to open and expand
Term
Decanting a Fully Aged/Mature Wine
Definition
Decant gently and consume immediately
Term
Decanting Wines with Sediment
Definition
Decant slowly and gently, watching the sediment
Term
Wine storage
Definition
Optimal conditions assist in slow, steady development;
-Cool (50-60 degrees F)
-Moderately Humid Environment (65-75%)
-Constant Temperature
-No Vibrations
-No Light
-Provide storage for bottles on side or at 45 degree angles
Term
Ullage
Definition
wine remaining in a container after some evaporation
Term
Odors Resulting from Sulphur Compounds
Definition
Sulfur Dioxide (SO2), Hydrogen Sulfide, (H2S); Mercaptan
Term
Sulfur Dioxide
Definition
characterized by pungent, burnt-matches smell accompanied by unpleasant tickling in nose and throat. Sensory effects of SO2 are directly related to pH. More acidic, more pronounced sulfur dioxide.
Term
Hydrogen Sulfide (H2S)
Definition
Odor of rotten eggs resulting from reduction of elemental sulfur. Yeast needs nitrogen, when none is available, Yeasts will break apart nitrogen-containing amino acids releasing S which then combines with H2 to become "light sulfides'
Term
Mercaptan
Definition
Onion or garlic-like odor created when sulfur dioxide and ethyl alcohol molecules bind.

SO2 + Ethanol =methyl mercaptan (treatable in winery)

SO2 + 2 Ethanol = diethyl mercaptan (untreatable)
Term

Definition
vinegar
Term
Ethyl Acetate
Definition

geranium-like scent; caused when sorbic acid (used to inhibit yeast) is put into tank before malolactic fermentation is complete
Term
Other Off-Odors
Definition
Aldehydic/Oxidized; Maderized; Stemmy; Lessy
Term

Definition
produced as alcohols are oxidized or excessive esterification;
Term

Cork Taint
Definition
3-5% wine bottled today is affected by cork taint; synthetic corks or screw-caps are alternative; Chlorine (used in bleaching) + Phenol (natural component in cork) = Trichlorophenol (TCP) + mold = TCA

Fungacides containing TCP + mold =TCA

Insecticides and Wood Preservatives containing Pentachlorophenol + mold =TCA
