Does prune juice have a taste?

Prune juice is a popular beverage made from dried plums, also known as prunes. It has long been used as a home remedy to help relieve constipation. Some people enjoy drinking prune juice for its unique flavor and taste, while others find its taste to be unappealing.

What Gives Prune Juice its Distinctive Flavor?

The taste of prune juice is often described as being sweet yet tart, with an earthy, plum-like flavor. The rich taste comes from its natural sugars as well as organic acids such as malic acid, quinic acid, and citric acid. These organic acids give prune juice its moderately tangy, sour taste.

When prunes are dried, the sugars they contain become very concentrated, intensifying their sweetness. Once rehydrated into prune juice, these sugars are diluted, creating a beverage that is mildly sweet with a subtle, fruity flavor.

In addition to natural sugars and acids, prune juice contains phenolic compounds that contribute to its taste. Phenolics are phytochemicals found in many fruits and plants that impart aromatic qualities. The phenolics in prunes add subtle notes of spice and bitterness to prune juice.

Factors That Influence the Flavor

There are a few factors that determine the specific flavor and taste of prune juice:

  • Prune variety – There are many cultivars of prunes, which vary somewhat in taste. Some are sweeter while others are more acidic or bitter.
  • Processing method – How the prunes are dried, processed, and bottled affects the final flavor.
  • Juice ingredients – Some juices have added flavors, sweeteners, or acids that enhance the plum taste.
  • Shelf life – Over time, prune juice loses some of its aroma and tends to taste more bitter.

These factors lead to variations in the intensity and balance of flavors between different brands and batches of prune juice.

What Does Prune Juice Taste Like? Common Descriptors

Here are some common words used to describe the distinct taste of prune juice:

  • Sweet – Prune juice has a mild, natural sweetness, usually less sweet than traditional fruit juices.
  • Tart – It has a moderately tart, sour taste from malic and citric acids.
  • Earthy – The flavor can be described as earthy or musty, like dried fruit.
  • Plum-like – It tastes similar to fresh or cooked plums.
  • Pruney – It has an identifiable dried plum or prune-like quality.
  • Spicy – There are hints of warmth, smokiness, or spice.
  • Bitter – Some bitterness comes through, especially in the aftertaste.
  • Mellow – When well-chilled, the taste is mellow, smooth, and well-balanced.

The intensity of these flavors can vary between different brands and batches. But in general, the taste of prune juice is multilayered, with sweet, tart, earthy, spicy, and bitter notes.

How Prune Juice Taste Can Vary

While prune juice always tastes fundamentally like prunes, there are some variations that affect its exact flavor profile:

  • Brand – Popular brands like Sunsweet or Kirkland have slightly different production methods, prune sources, and ingredient formulas that impact the taste.
  • Blends – Some prune juices are blended with flavors like apple, pear, or grape for a more fruit-forward taste.
  • Added Ingredients – Juices with extra sweeteners, vitamin C, or preservatives may taste less tangy or natural.
  • Prune Type – Prune variety (Italian, French, etc.) makes a subtle difference in the prune juice taste.
  • Vintage – Like wine, each year’s prune crop varies somewhat due to ripening conditions.
  • Bottle Size – After opening, the taste can change and start to lose freshness sooner in larger bottles.
  • Shelf Life – Over time, opened prune juice oxidizes and tastes less vibrant.

Despite these variations, most commercially produced prune juices have a signature sweet, tart, and earthy taste that is instantly recognizable as prune juice. However, some brands or types align more closely with individual flavor preferences.

Prune Juice Taste Preferences

People have different preferences when it comes to the taste of prune juice:

  • Some enjoy a very sweet, mild juice with just a slight tart edge.
  • Others like the robust, tangy taste of traditional prune juice.
  • Some think it tastes best when chilled and consumed fresh.
  • Others dislike the earthy flavor and add juice or sweetener to mellow it.

Here is a comparison of some popular prune juice brands and products:

Brand Taste Description
Sunsweet Balanced sweet and tart flavor, robust prune taste
Kirkland Mild, light taste and moderate tartness

Trying different brands allows you to find a prune juice with a taste profile that suits your preferences.

Acquiring a Taste for Prune Juice

For some, prune juice has an unappealing bitter or earthy taste when they first try it. Here are some tips for acquiring a taste for it:

  • Chill it thoroughly – The flavor is smoother and more balanced when ice cold.
  • Drink high-quality brands – The taste is fresher and more vibrant than generic versions.
  • Mix with fruit juice – Apple or pear juice smooths out the earthy edges.
  • Sweeten to taste – Adding a bit of honey, maple syrup, or sugar cuts the tartness.
  • Drink it slowly – Small sips allow the palate to adjust to the unique flavors.
  • Have it with food – Pairing it with sweet foods enhances the drinking experience.

Over time, your palate will likely become accustomed to the complex taste profile, allowing you to appreciate and even enjoy the many nuanced flavors.

Health Benefits Despite the Taste

While prune juice may require an acquired taste for some, it provides many proven digestive health benefits:

  • Relieves constipation thanks to its fiber, fructose, and phenolic compounds.
  • Acts as a mild laxative when consumed in larger amounts.
  • Helps maintain regularity and intestinal flow.
  • Contains antioxidants that support gut and digestive health.

Here is a summary of the key compounds that make prune juice effective for digestive regularity:

Compound Effect
Fiber Adds bulk and aids elimination
Sorbitol Natural laxative compound that draws moisture into the intestines
Phenolic acids Stimulate contraction of the gastrointestinal tract
Fructose Natural sugar that has a mild laxative effect when rapidly absorbed

This unique combination of compounds allows prune juice to act as both a stool softener and a mild laxative. So even if the taste takes some getting used to, the benefits make it worth trying.

Tips for Enhancing Prune Juice’s Palatability

If you want to make prune juice more palatable, here are some simple tips:

  • Chill it thoroughly before drinking to improve the flavor
  • Pour over ice to dilute and mellow the taste
  • Sweeten with a bit of honey, maple syrup, or sugar
  • Mix with sweeter fruit juices like apple, pear, or grape
  • Blend with yogurt, milk, or ice cream for a smoothie
  • Stir in a sprinkle of cinnamon or nutmeg
  • Sip through a straw to minimize contact with taste buds
  • Hold your nose while swallowing to avoid the earthy aroma
  • Keep a strong mint or citrus lozenge handy to freshen breath

Making it more drinkable means you can keep getting those digestive benefits without dreading the taste.

Does Prune Juice Go Bad or Expire?

When properly stored, prune juice can last for quite a while after opening. But it does gradually lose quality and flavor over time. Here’s how to tell if prune juice has expired or gone bad:

  • Check the expiration date on the bottle.
  • Inspect the color – it darkens and may appear muddy or cloudy when old.
  • Give it a sniff – spoiled prune juice smells yeasty, fermented, or off.
  • Taste a sip – expired prune juice often tastes bitter, medicinal, or chemically.
  • Watch for signs of fermentation – bubbles, off gassing, or an effervescent quality.
  • Pay attention to changes in consistency – it can thicken or take on a spoiled milk texture.

If your prune juice displays any of these characteristics, it’s best not to drink it. For maximum freshness and flavor, try to finish prune juice within 4-6 months of opening and refrigerate after opening.


Prune juice definitely has a unique and characteristic taste. While some find it pleasantly sweet and fruity, others dislike its earthy, tart, bitter qualities. The exact flavor profile varies by factors like brand, vintage, ingredients, and storage conditions. But in general, the taste of prune juice is like concentrated, liquefied prunes with tangy, fermented undertones. Many suggest enhancing the flavor by chilling, diluting, sweetening, or mixing prune juice with other beverages. And despite its polarizing taste, prune juice remains popular due to its proven ability to stimulate bowel movements and maintain digestive regularity.
