I’m sure at some point you’ve seen someone or you’ve have opened a bottle of wine and smelled the cork – everything seemed find and then when you poured the wine into the glass it smelled like stinky socks. YUCK! Well in this blog I am going to go over how to tell if a wine is corked!

What does “Corked” mean?
Cork is a natural product taken from trees – it is the bark from the cork tree, which is one of the only (to my knowledge) trees that has a “self healing” property and the cork bark will grow back if stripped correctly. However, since it is natural that means that no matter how many times you sanitize it, there is still a chance that some bacteria can build up, fester and then built up a “funk” to it. When a cork is tainted or a wine is “corked” is a chemical called Trichloroanisole or known in the biz as “TCA”.
This chemical effects between 2-3% of bottles, which doesn’t sound it is too bad but if you are a regular wine drinker…or an enthusiastic wine drinker you’ll probably encounter about 100 bottles in your adult life – give or take.
How To Tell If Your Wine Is Corked
Now, if you’ve never had the unfortunate experience of smelling tainted wine it can be hard to understand what this smell is like firsthand, but once you’ve smelled it – trust me you’ll never forget it! One way to pick out whether or not a wine is corked, though, is to smell and taste it and try to pick out the notes youโve come to expect from that wine style. If a wine typically smells fruit-forward, but youโre not picking up any fruit notes, you can be pretty confident that somethingโs not right.

How to Detect It
When there is A LOT of cork taint or TCA in your wine it is going to smell like:
- Wet Cardboard
- Wet Dog
- Wet Newspaper
- Basically anything gross and wet
- Grandma’s basement or attic
If there is only a little cork taint or TCA in your wine it is going to smell like:
- Dull (like lack of vibrant aromas)
- Little to no or a burnt taste
Cork Taint (TCA) Checklist
- The wine has a real cork. Not screw top or a synthetic (aka plastic) cork
- Does the wine have tasting notes or reviews that donโt line up with whatโs in your glass?
- Is your palate acting up? (drink some water, smell your forearm (trust me) and re-sniff)
- Does your drinking buddy think itโs corked too?
Is Corked Wine Safe to Drink?
Technically, yes. It just isn’t as an enjoyable experience as your other, non-tainted bottles of wine. The chemical built up doesn’t effect the overall “drink-ability” of the wine but personally, I’d find another bottle.

What next?
If you are drinking a bottle of wine at a restaurant it is just like if you were going to send back a dish because it isn’t what you ordered, like you wanted a medium-rare steak and you got well-done. You’re paying for it, send it back. If you purchase the wine from a retailer, most shops will take back a bottle of tainted wine and refund or exchange the bottle for you. Obviously, they won’t take it back if you empty the bottle and then ask for the bottle to get exchanged but most shops will do this for you.
So, my wine-loving buddy, now you know what to do if you encounter a tainted bottle of wine. Keep your spirits high, your taste buds adventurous, and let the wine-fueled celebrations continue! Cheers to you and the beautiful chaos of life. For more wine articles, click here!
