Faults Aroma Recognition Training Kit - 30 Signature Faults from Acetaldehyde to Wet Dog
Think your palate is sharp? Let’s put it to the test. This Faults Aroma Recognition Kit features 30 of the most common off-notes and defects found in wine, beer, and spirits — from vegetal funk and oxidized paper to the dreaded wet dog. Whether you’re a brewer, distiller, or just obsessive about your pours, this “box of bad smells” is a must-have for sharpening your senses and spotting flaws before your customers do.
Sometimes knowing what not to taste is just as important as knowing what’s right. This professional-grade Faults Aroma Kit from Aroma Academy includes 30 aromatic essences that represent the most frequently encountered flaws in fermentation, maturation, and packaging — including TCA (cork taint), DMS, acetic acid, and more.
Perfect for sensory training, off-flavor panels, or educational tastings, the kit can be used traditionally with aroma-neutral strips or to “spike” tasting samples for blind fault recognition. It includes multiple concentration levels for certain compounds to help train detection thresholds — ideal for producers, QC teams, sommeliers, Cicerones, and hardcore enthusiasts who want to take their flavor game to the next level.
With a reusable scoresheet and detailed training manual, this kit turns your nose into your best tool for quality control. It’s the ultimate system for making sure that the next thing you serve is your best.
