Welcome back to our educational series! We've explored grape clones, fermentation, and perfect pairings, but what happens when a wine isn't quite right? This week, we're delving into a less glamorous but equally important topic:Understanding Wine Faults.
While rare, encountering a "faulty" bottle can be disappointing. Knowing how to identify common wine faults empowers you to understand what you're tasting (or smelling!) and helps you appreciate the many perfect bottles even more. It's not about being a critic, but about being an informed enthusiast!
Let's explore the most common culprits:
Common Wine Faults and How to Spot Them:
- Cork Taint (TCA - Trichloroanisole)
- What it is:The most infamous fault, caused by a chemical compound that contaminates corks (and sometimes barrels or wineries).
- How to spot it:The wine will smell like a damp, musty basement, wet cardboard, mouldy newspaper, or wet dog. The fruit flavours will be muted or completely absent, leaving the wine tasting flat and dull. This fault affects around 1-3% of wines sealed with natural cork.
- Oxidation
- What it is:Too much exposure to oxygen, often due to a poor seal, old age (past its prime), or improper storage.
- How to spot it:
- Appearance:White wines will turn a darker golden or brownish colour. Red wines will lose their vibrant red hues and become brick-orange or brown.
- Aroma/Taste:The wine will smell like bruised apples, stale nuts (like sherry, but not in a good way for table wine), or even vinegar. It will taste flat, lacking fresh fruit, and may have a sharp, acrid finish.
- Reduction (Sulfur Compounds)
- What it is:The opposite of oxidation – too little oxygen during winemaking, leading to the formation of sulfur compounds.
- How to spot it:Can manifest in various unpleasant aromas: struck match, burnt rubber, rotten eggs, or even cooked cabbage. Sometimes, these aromas can "blow off" with aeration (swirling the glass vigorously or decanting).
- Volatile Acidity (VA)
- What it is:Caused by acetic acid bacteria (the same bacteria that turn wine into vinegar) and ethyl acetate. A tiny amount can add complexity, but too much is a fault.
- How to spot it:The wine will smell like vinegar, nail polish remover, or even super glue. It can also give the wine a sharp, sour taste.
- Brettanomyces (Brett)
- What it is:A wild yeast (often referred to as "Brett") that can grow in wineries and impart distinctive, often undesirable, aromas.
- How to spot it:Smells like a barnyard, horse stable, band-aid, or even a sweaty saddle. Some people tolerate low levels of Brett, while others find it completely off-putting.
- Lightstrike
- What it is:Damage caused by exposure to strong light (especially fluorescent or sunlight), typically affecting wines in clear or light-coloured bottles.
- How to spot it:The wine develops unpleasant aromas of wet wool, cooked cabbage, or even skunk. This is why many wines are bottled in dark glass!
What to Do If You Encounter a Fault:
If you open a bottle and suspect it's faulty, trust your nose and palate. Most reputable wine merchants and restaurants will happily replace a corked or otherwise truly faulty bottle. Don't hesitate to reach out to us if you believe a wine purchased from us is affected.
Understanding these faults helps you appreciate the countless bottles that are perfectly crafted and stored. The vast majority of wines you'll encounter are delicious and true to their character!
