Wine Cork

The horror – you have just opened a bottle of one of your favs and something is off. It doesn’t smell or taste the way you remember it. Wine is a natural, living thing – so it is quite possible something has gone awry – but the upside is winemakers always replace faulty wine* and screwcaps lower the chances of wine faults. Rather than suffering through – try our little cheat sheet for the top suspects.


Cork taint or corked wine – caused by microbial fungi in natural cork that creates TCA (stands for 2,4,6-trichloroanisole). At higher levels, it smells mouldy or musky, a bit like wet cardboard or a damp basement. At lower levels, it strips the wine of its flavour and can be a bit astringent.  It is only in natural cork – so screwcaps are a-ok – and it has nothing to do with crumbly corks or crystals. It can’t hurt you – it’s just a downer!


Oxygen has as many upsides as downsides – we need it to ‘let the wine breathe’, to open up the aromas in a wine when you decant, and a little is needed to help wine mature – but too much and it will fall over. Red wines lose colour and become flat – if you’ve every left out a glass overnight after a party – it starts to smell like copper and vinegar – that is ethanol (alcohol) becoming acetaldehyde.  It can be a feature in oxidatively handled Port, Jura white wines or Sherry – but it can also give wine zero aromas and a lacklustre palate.


Ever left a bottle of wine in the car during summer? You might have cooked wine. Generally, wine can handle incremental temperature changes over the seasons – but diurnal (night to day) temperature shocks are bad news. The pressure from the heat in the bottle can push out the cork a bit – and the flavour will be like stewed fruit, burnt, caramel or just plain flat. Try giving it a decant and rest for half an hour – but if it’s still not right then just return it.
