What’s the Bitter Taste After Wine?

what's the bitter taste after wine

It’s an unpleasant surprise to sniff a rich bouquet of fruits in your glass of wine and take a confident sip that delivers an intensive burst of flavor, only to have a nasty bitterness settle in your mouth. What’s going on? Why’s your wine bitter?

If you taste bitterness after you swallow a sip of wine, you’re tasting the alcohol in what’s called the wine’s finish. You’re more likely to taste bitterness after swallowing if the wine’s high alcohol (over 13% ABV). You will also taste bitterness if the wine is out of balance, even in lower alcohol wines. Well made wines will taste like fruit, flowers, or other pleasant flavors after you swallow, and won’t be bitter.

Why Is My Wine Bitter After Swallowing?

Alcohol tastes bitter. Take a sip of tequila or vodka and it’s really bitter.

That’s the alcohol.

Hard liquor and spirits have more alcohol than the average bottle of wine, so it’s easy to taste. A bottle of wine is anywhere from 5% to 22% alcohol.

A wine’s bitterness from the alcohol will be less apparent in lower alcohol wines and more obvious in higher alcohol wines.

Wines that aren’t well integrated, meaning that the flavors, acid, tannin, and alcohol don’t come together harmoniously, can have a bitter finish. In well-made wines, the finish ends in pleasant flavors, not bitterness.

What Is a Wine’s Finish?

The finish of the wine is how it tastes after you swallow. All wines have a distinctive finish. Some wines end on fruit, like cherry or apple. Other wines have a more floral finish, like white blossom or violet. Still other wines have toast, vanilla, or even mineral notes. A wine’s finish will depend on the grapes, the wine’s age, and the winemaking techniques.

Your wine’s finish may taste like this:

  • Floral notes – like lavender or rose – good
  • Fruit – like apple, citrus, cherry, or plum – good
  • Sweetness – from sugar in the wine – good
  • Herbs – like grass or hay – good
  • Spice – like cinnamon or cloves – good
  • Smoke – like mocha, coffee, or toast – good
  • Butter – common in Chardonnay – good
  • Bitterness – Out of balance
  • High acid – like sourness – Out of balance
  • Funk or mold – the wine’s faulted – bad
  • Barnyard – the wine’s faulted – bad
  • Mouse Urine – the wine’s faulted – bad

The best wines in the world have long, lingering finishes that can last for several minutes. Imagine taking a sip of wine and still tasting intense fruit, savory spices, or delicate mineral notes for several minutes. A drawn out finish is one of the most intoxicating qualities in an epic bottle of wine.
