Beer Defects

Beer Defects

Beer Defects is an application containing detailed information about aroma and flavor defects found in beer. Beer 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 beer
•Approximate flavor threshold
•Possible causes
•Possible treatments
•Possible prevention

FEATURES
Sensory descriptors (what it smells or tastes like) include:
∗Banana, estery
∗Nail polish, solvent, glue
∗Bruised apple, sherry, nutty
∗Phenolic, smoky, clove-like
∗Antiseptic, hospital, plastic, vinyl
∗Cheesy, sweat socks, old hops, putrid
∗Rancid butter, butterscotch
∗Rotten egg, sulfidic
∗Skunky, lightstruck
∗Canned corn, molasses, vegetal
∗Cardboard, paper, oxidized
∗Vinegar, sour
∗Aroma and flavor defects can be searched by sensory descriptors or by chemical name (molecule responsible for the defect)
∗General information about sensory thresholds
∗Good sanitation techniques

WHO COULD USE IT?
Quick and accurate identification of off-aromas and flavors is advantageous for:
•Professional brewers
•Brewery laboratory and cellar staff
•Home brewers
•Instructors for beer programs
•Students in beer programs
•Beer judges
•Bartenders
•Beer merchants and staff
•Restauranteurs
•Beer writers
•Savvy beer consumers

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

•For beer merchants, avoiding losses associated with defective beers improves the profit margin.

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