What are Bitters Made Of?

Bitters are considered spirits infused with different types of botanicals, including spices, leaves, barks, fruits, roots, and herbs. In short, it’s a type of alcohol that is infused with different plant matters.

Bitters comprise three parts— a neutral spirit, aromatics, and a bittering ingredient.

The most commonly used neutral spirit for bitters production is grain alcohol. Grain alcohol is the liquor of choice because of two main reasons. (*)

First, it has a strong alcohol content which is beneficial in maximizing the extraction and preservation of flavor. Second, it’s a neutral spirit that can highlight the flavor and character of the infused botanicals used.

On the other hand, the ingredients used for the other two parts vary a lot. For the bittering ingredient, some of the best options you have are:

  • Sarsaparilla
  • Licorice Root
  • Wormwood
  • Koala Nuts
  • Wild Cherry Bark
  • Dandelion Root
  • Angelica Root

With regards to aromatics and spices, you can choose from these ingredients:

  • Mint
  • Hibiscus
  • Chamomile
  • Valerian Root
  • Cinnamon
  • Lemongrass
  • Coriander
  • Cardamom
  • Cloves

Do Bitters Go Bad?

As liqueurs, bitters contain a high amount of alcohol. Case in point: Angostura bitters have an ABV of up to 45%.

Its high ABV makes its shelf life comparable to that of other spirits-= essentially indefinite.

So can bitters go bad? The simple answer is not likely.

But there’s one small catch: While bitters will most likely not go bad for decades, but its flavor and taste will eventually start to deteriorate as the years go by.

How Long Do Bitters Last?

Like other spirits containing alcohol, most bitters are also susceptible to evaporation and different chemical reaction—two common causes of flavor and quality change in alcoholic drinks.

So what does this mean? It means that you should finish off that bottle of Angostura bitters within a few months to years after opening if you want to enjoy it at its best quality,

But wait, there’s more. As we’ve said, there might be an exception to this rule.

Have you ever seen, bought, or used a bottle of fruit bitters from Fee Brothers?

In their bottle, you can find the instruction saying: refrigerate after opening, which implies that it comes with an expiration date or it may have a limited shelf life.

Well, that’s sort of true. Some bitters may go bad over time, and these are the fruit bitters dissolved in glycerin instead of ethanol.

Why is this so? Glycerin has a shorter shelf life than ethanol and can last only 1 to 2 years, so these bitters will definitely spoil beyond this short shelf life or expiration date.

And since these contain glycerin or sugar alcohol, an alcohol enthusiast may not consider them true bitters.

How to Store Bitters Correctly?

When it comes to storing bitters, the most common question is: should you refrigerate bitters? Here’s a simple answer: No.

Since alcohol acts as a natural preservative, you don’t need to refrigerate bitters to extend their shelf life or prevent them from spoiling.

With that said, the best way to store bitters is to keep them away from heat and light to prevent chemical reactions. That’s why you should store bitters in a cold, dry, and dark place like your kitchen cabinet, pantry, or cellar.

But again, there’s one exception: an opened bottle of fruit bitters produced using glycerin has to be refrigerated.
