Deductive Tasting Flashcards
Gain a working mastery of the subject.
The criteria of the Deductive Tasting Method (4)
1-Sight
2-Nose
3-Palate
4-Conclusion: initial and final (theoretical deduction)
What does SIGHT allow you to deduct?
- Provides valuable information about a wine’s possible grape variety, age and/or condition.
- During this phrase, you may develop suspicions but it is cautioned against making final confirmations.
How should you evaluate wine, sight wise?
- Tilt the glass away from you against a white background in the best light you can find.
- Hold the glass by the stem.
- Utilize a cleaned and well-buffed wine glass.
Filtered vs. Unfiltered wine
Filtered: typically from New World, go through sterile filtration and bottling to remove bacteria and proteins that can cloud wine.
Unfiltered: some producers of high quality wine believe that only natural fining and filtration should be used, anything more strips wine of its flavors.
Define: Brightness
the capacity of a wine to reflect light - a function of clarity.
The brightness scale (6 levels)
Dull - Hazy - Bright - Day Bright - Star Bright - Brilliant
What does a wine’s color / hue all you to deduct?
-clues to a wine’s age, storage conditions or grape variety.
White and blush wines grow ______ with age. (generally speaking)
Darker
Red wines grow _____ with age (generally speaking)
Lighter
Pigments and tannin in red wines precipitate into _________ with age. (generally speaking)
Sediment.
What can secondary colors tell you about a wine?
-Age, climate or variety.
_________ in young or cool climate white wines (secondary colors)
Green
_______, _________, __________ in older red wines ( secondary colors)
- Orange
- Yellow
- Brown
White wines (5) (color scales)
Watery - Straw - Yellow - Gold - Brown
Pink wines (3) ( color scales)
Pink - Salmon - Brown
Red Wines (5) (color scales)
Purple - Ruby (Red) - Garnet (Reddish Brown) - Orange - Brown
Rim Variation (what and why)
- The difference in color between wine at the center of the glass and the wine at the edge (rim) of the glass.
- A phenomenon of age.
- The older the wine, the more rim variation.
What is sediment? (Sight)
- Pigment and tannins that precipitate out of solution as red wine ages.
- Sediment also found in young unfiltered red wines.
Tartrates (Wine Diamonds)
-tiny, crystalline deposits that occur in
wines when potassium and tartaric acid, both naturally occurring products of grapes, bind together to form a crystal.
-Excess tartartic acid
-Present in all wines
-Often removed through filtration or cold stabilization.
(less common in red wines, as their level of
tartaric acid is lower, and crystals tend to fall out naturally during the longer barrel-aging process. )
Legs/Tears - Viscosity
- alcohol or presence of residual sugar in wine
- —> Thin, quickly moving legs or sheeting in the glass = low alcohol and little or no residual sugar
- —> Thick, slowly moving legs = higher alcohol or the presences of residual sugar.
What is the most importance aspect of the Deductive Tasting Method?
Nose, smell accounts for some 85% of taste
Why and how do we swirl a glass of wine?
Volatilizing (disperse in vapor) the esters - releasing the flavor elements attached to the alcohol molecules in the wine.
Wine Flaws (Nose)
- TCA (corkiness)
- Oxidation and Heat Damage
- Volatile Acidity (VA)
- Excess Sulfur Dioxide (SO2)
- Brettanomyces
- Hydrogen Sulfide (H2S)
TCA - Corkiness ( Wine Flaws)
- from taint corks - wet moldy cardboard and mustiness
Oxidation and Heat Damage ( Wine Flaws)
- from age or poor storage conditions - dull fruit, cooked fruit, secondary and tertiary aromas and flavors (leather), vegetal notes, flat finish
Volatile Acidity (VA) ( Wine Flaws)
-vinegar aromas (acetobacter) or varnish/fingernail polish aromoas (ethyl acetate or EA)
Excess Sulfur Dioxide (SO2) ( Wine Flaws)
-added during the wine-making process - matchstick or wet wool
Brettanomyces ( Wine Flaws)
- varying yeast strains
- aromas range from smoke, clove, spice to band-aid and manure.
- Due to high pH available from nutrients such as residual sugar, inadequate topping, and infected barrels.
What is the flaw scale?
- Sound/Clean OR Unsound/Faulty
- If faulty, then say what fault.
