Wine Defects

Wine Defects

Wine Defects is an application containing detailed information about aroma and flavor defects found in wine. Wine defects – also known as faults – are noticeable and objectionable departures from an acceptable norm.

The application is a complete reference to 12 common defects which may occur, and includes:
•Molecule responsible (chemical name)
•Chemical formula
•Main origins
•Typical concentration in wine
•Approximate aroma threshold
•Possible causes
•Possible treatments
•Possible prevention

FEATURES
Sensory descriptors (what it smells or tastes like) include:
∗Bell pepper, green, unripe
∗Vinegar, sour
∗Nail polish, solvent, glue
∗Bruised apple, sherry, nutty
∗Rotten egg
∗Natural gas, onion, garlic
∗Rancid butter
∗Medicinal, band-aid, leather, barnyard, horse sweat
∗Smoky, spicy, barbeque
∗Mouse urine, rancid nuts
∗Musty, dank cellar, wet cardboard
∗Burned match, causes chocking
∗Aroma and flavor defects can be searched by sensory descriptors or by chemical name (molecule responsible for the defect)
∗General information about sensory thresholds
∗How to prevent stuck fermentations

WHO COULD USE IT?
Quick and accurate identification of off-aromas and flavors is advantageous for:
•Professional winemakers
•Enologists
•Winery laboratory and cellar staff
•Hospitality staff
•Home winemakers
•Instructors for wine programs
•Students in wine programs
•Wine judges
•Sommeliers
•Bartenders
•Wine merchants and staff
•Restaurateurs
•Wine writers
•Wine collectors
•Savvy wine consumers

WHY USE IT?
•For winemakers, early remedial action can often correct the problem, before the fault becomes more serious or irreversible.

•For wine merchants, avoiding losses associated with defective wines improves the profit margin.

•Wine consumers should also know more about wine off-aromas and flavors so that rejection is based on genuine defects, not unfamiliarity.
