Wine Faults You Can Actually Detect
You do not need a lab. You need language for “this bottle is damaged” versus “I dislike the style.”
Common faults
| Clue | Possible issue | What to do |
|---|---|---|
| Wet cardboard / mouldy basement | Cork taint (TCA) | Do not “air it out” hoping for magic |
| Sherry-like when it should be fresh | Oxidation | Return if retail allows |
| Cooked jam + flat | Heat damage | Avoid warm-shelf bottles next time |
| Struck match that will not blow off | Reduction (sometimes temporary) | Swirl/decant briefly; if stuck, move on |
| Vinegar / nail polish extremes | Volatile acidity / spoilage | Stop pouring for guests |
Style vs fault
Some bitterness, earth, or funk is style. If you are unsure, compare with a second healthy bottle of a wine you know.
Style versus damage
Earth or mild funk can be style; wet cardboard, vinegar spikes, and cooked-flat aromas are not. When unsure, open a known-good bottle for calibration before blaming your palate.

Checklist
- Define the outcome you want from this topic in one sentence.
- Note constraints (budget, time, equipment, dietary needs, client type).
- Apply the core method on this page once without improvising mid-way.
- Change a single variable if results disappoint.
- Write a two-line note for next time (what worked / what failed).
Common mistakes
- Skipping fundamentals to buy gear or hacks
- Copying advice from a different country or context without adapting
- Changing three variables at once so you learn nothing
- Ignoring primary sources when rules/safety matter
- Publishing opinions without criteria (for rankings)
Quality bar
A good result is repeatable, explained, and honest about trade-offs. If a tip only works in perfect conditions, treat it as optional.
Site connections
Use related links below and the site navigation to move between planning, method, and reference pages. Prefer this site’s guides over random threads when you need UK-relevant process.
Table note
Temperature, glassware, and water quality change drinks more than prestige labels. Host non-drinkers with equal ritual. Keep notes on bottles and beans you would rebuy.

What “good” looks like
You should leave this page able to make a decision, not only collect vocabulary. If you cannot name the next action, re-read the checklists and apply one item today.
Trade-offs to accept
Every method has costs: time, money, attention, or risk. Prefer explicit trade-offs over secret hacks. If a tip requires perfect conditions, treat it as optional.
Record keeping
Write two lines after you try something: result and next change. Future-you will thank present-you more than another bookmarked article would.

Common faults (plain language)
| Clue | Possible issue |
|---|---|
| Wet cardboard / musty | Cork taint (TCA) |
| Vinegar / nail polish | Volatile acidity / spoilage |
| Sherry-like when it should be fresh | Oxidation |
| Flat sparkling | Lost carbonation / poor seal |
What to do
Stop serving. Air does not fix cork taint. Compare with a second bottle if you have one. Keep evidence if returning.
Not every unusual note is a fault
Some styles are oxidative on purpose. Context matters. When unsure, ask a trusted merchant rather than Twitter.
