To Refrigerate, or Not to Refrigerate Bitters: Angostura Official Word

To Refrigerate, or Not to Refrigerate Bitters

Do not be scared.  The word alone conjures up a Yuk! reaction in many not familiar with this aromatic and flavoring.  Bitters are that mystery ingredient in various cocktails, sauces, syrups, and fruit dishes that you enjoy eating.  

“Made with the same original secret recipe since 1824, the world famous Angostura® aromatic bitters remains the quintessential and definitive ingredient for classic and contemporary cocktails.  Angostura® aromatic bitters also adds its unmistakable flavour and aroma to 'soft' beverages and desserts.”  

The secret recipe originated with Dr. Diegert in 1824, “to use in his medical practice as Surgeon General to the armies of Simon Bolivar. He resided in the town of Angostura in Venezuela, this town is now called Ciudad Bolivar.”  Bitters often include essences from herbs, orange peel, cascarilla (a fragrant Caribbean shrub), and cassia (cinnamon).  

I recently used Angostura Bitters and was not sure if I needed to refrigerate after opening the bottle.  (*Note:  the Angostura oversized label was initially an error in manufacturing that was never corrected and became a signature.)  I did not see any notes about how to store the product on the label.  Nor could I find a definitive answer online.  I decided to contact the company and get the official word.  

After opening the bottle you do not need to refrigerate Angostura Bitters.

Also, there is no expiration after opening the bottle.

  1. Did you ask them what the after opening shelf life is?

  2. This comment has been removed by the author.

  3. I did find out from Angostura, "No, there is no expiration date. (even after opening the bottle)". Thank you for the question.

  4. We have a bottle that is about 25yrs old - would that still be okay?

  5. According to Angostura, "Also, there is no expiration after opening the bottle." I can imagine though that a new bottle probably has better flavor. I would go with a new bottle for that reason.

  6. This is one of the highest quality blog posts I have read. To the point, from the source.

  7. I have a bottle 30 years old and it is fine. I wonder if the alcohol content is a preservative. A refreshing Summer drink is gin, bitter lemon and angostura bitters served over ice.

  8. Appreciate your cocktail. Please make sure to visit Pointe Viven again or sign up for updates.
    Thank you, -Jesse

  9. Thank you. I wanted to make an old fashioned and wasn’t sure if my bottle was still good (it’s been a year since I purchased it). 🥃🤘🏻
