Rhubarb, with its vibrant red stalks and tart flavor, is a beloved ingredient in pies, sauces, and even savory dishes. However, like many fresh produce items, the longevity of rhubarb after harvesting is often a concern for home cooks. Knowing how long rhubarb will last in the refrigerator and how to properly store it can prevent food waste and ensure that your dishes taste their best. In this comprehensive guide, we will explore the various factors affecting rhubarb’s shelf life, storage tips, and much more.
The Basics of Rhubarb: Understanding Its Composition
Before delving into storage methods, it is essential to understand what rhubarb is and what makes it unique. Rhubarb (Rheum rhabarbarum) is a perennial plant known for its thick, succulent, edible stalks, which are typically reddish-green in color. The leaves of the rhubarb plant are toxic and should never be consumed.
Rhubarb is low in calories and high in fiber, making it a healthy addition to your diet. Its tart flavor profile is primarily due to the presence of organic acids, such as malic acid. This unique taste makes rhubarb an excellent base for desserts, especially when paired with sweeter fruits.
How Long Will Rhubarb Last in the Refrigerator?
When stored properly, fresh rhubarb can last anywhere from five to ten days in the refrigerator. Several factors, including the freshness of the rhubarb at the time of purchase, how it’s stored, and the overall temperature of your refrigerator, can influence its shelf life.
Factors Influencing the Shelf Life of Rhubarb
To understand why rhubarb may not last as long as other fruits or vegetables, consider the following factors:
1. Freshness at Purchase
The quality of rhubarb at the time of purchase plays a crucial role in determining its shelf life. Fresh rhubarb stalks will last longer than those that are already starting to wilt or discolor.
2. Storage Conditions
The way you store rhubarb affects its longevity. Rhubarb should be kept in a cool, dry place inside the refrigerator, ideally in the crisper drawer designed to maintain a slightly higher humidity level.
3. Preparation Method
If you have cut or trimmed the rhubarb, its shelf life may decrease because the exposed areas may start to wilt and decay faster. The cooking method can also impact the remaining quality if you’re dealing with leftover cooked rhubarb.
Storage Tips for Prolonging the Life of Rhubarb
To maximize the freshness and longevity of your rhubarb, consider these effective storage tips:
- Keep in Crisper Drawer: Store your rhubarb in the vegetable crisper drawer of your refrigerator, which provides the optimal environment for keeping fruits and vegetables fresh.
- Wrap in Damp Paper Towel: Wrapping rhubarb in a slightly damp paper towel and placing it inside a plastic bag can help maintain its moisture while allowing for proper airflow.
Signs That Rhubarb Has Gone Bad
Recognizing the signs of spoilage is crucial for ensuring that you are not consuming spoiled produce. Here are some indicators that your rhubarb has gone bad:
- Wilting Stalks: If the stalks have become floppy and limp, it’s a sign that they are past their prime.
- Discoloration: Look for dark spots or a significant change in color—this may indicate decay.
When to Freeze Rhubarb for Longer Shelf Life
If you have excess rhubarb or want to preserve its nutritional benefits beyond a week, freezing is an excellent option. Freezing rhubarb is simple, and it can last up to 12 months in the freezer.
How to Freeze Rhubarb
Follow these steps to properly freeze rhubarb:
- Prepping Rhubarb: Start by washing the rhubarb stalks thoroughly. Trim off any wilted or discolored portions and cut them into 1-inch pieces.
- Blanching (Optional): Blanching is not necessary but can help maintain flavor and color. To blanch, immerse the rhubarb pieces in boiling water for one minute, then quickly transfer them to ice water.
- Dry and Pack: After blanching (or if you skip that step), dry the rhubarb pieces with a clean towel, then pack them into airtight freezer bags. Be sure to remove as much air as possible.
- Label and Freeze: Label each bag with the packing date and store them in the freezer. Remember to use each batch within a year for optimal quality.
Using Frozen Rhubarb

How long can rhubarb be stored in the refrigerator?
Rhubarb can typically be stored in the refrigerator for about one to two weeks, depending on its freshness at the time of purchase and how it is stored. Fresh, unwashed rhubarb, when kept in a perforated plastic bag or wrapped in a damp paper towel, can maintain its quality for a longer period. It’s crucial to ensure that the rhubarb is dry before storage, as excess moisture can lead to quicker spoilage.
For optimal freshness, you should regularly check the rhubarb during storage. If you notice any signs of wilting or discoloration, it’s best to use it promptly. The key to prolonging shelf life is preventing moisture buildup and minimizing exposure to air, which can lead to spoilage and loss of flavor.
Can rhubarb be frozen for later use?
Yes, rhubarb can be frozen for later use, and this is a great way to extend its shelf life significantly. To freeze rhubarb, first, wash, trim, and chop the stalks into manageable pieces. Blanching the rhubarb in boiling water for one to two minutes before freezing can help preserve its color and flavor, though it’s not strictly necessary. After blanching, cool the pieces in ice water, drain, and then spread them on a baking sheet to freeze individually before transferring to airtight freezer bags.
When properly frozen, rhubarb can last up to 12 months in the freezer, making it a versatile ingredient for various recipes, including pies, jams, and sauces. Just be aware that frozen rhubarb may have a slightly softer texture when thawed, so it is best suited for cooked recipes rather than fresh applications.
What are the signs of spoiled rhubarb?
Common signs of spoiled rhubarb include wilting leaves, soft or mushy stalks, and discoloration. If the stalks appear slimy or produce an off-putting odor, they have likely gone bad and should be discarded. Another red flag is the presence of mold or black spots, which indicate spoilage and may present health risks if consumed.
If you notice any of these signs, it’s crucial to evaluate the overall condition of the rhubarb. Even if only a portion appears spoiled, it’s generally better to err on the side of caution and discard the entire batch to avoid any unpleasant experiences or health concerns. Fresh rhubarb should have a firm texture and a vibrant color, so always aim to select the best quality.
Should rhubarb be washed before storing it in the refrigerator?
It’s generally recommended to avoid washing rhubarb before storing it in the refrigerator. Excess moisture can accelerate spoilage, leading to a shorter shelf life. Instead, it’s best to wash the rhubarb just before you plan to use it. When washing, make sure to clean the stalks thoroughly under cool running water to remove any dirt or residue.
If you feel it’s necessary to wash rhubarb before storing, use a damp paper towel to gently wipe the stalks rather than submerging them in water. This approach removes surface dirt without adding excess moisture, which can lead to rot. Remember that proper storage techniques, such as using a perforated plastic bag or wrapping it in a cloth, are critical for maintaining freshness.
What is the best way to store rhubarb in the refrigerator?
To maximize the shelf life of rhubarb in the refrigerator, the best method is to store it unwashed and wrapped in a damp paper towel. Place the wrapped rhubarb in a perforated plastic bag or an open container to allow air circulation. This method helps maintain the moisture balance and prevents the stalks from drying out, retaining their crispness and flavor.
It’s essential to place the rhubarb in the crisper drawer of the refrigerator, where the temperature and humidity levels are more suitable for storing fruits and vegetables. Regularly check the rhubarb for signs of spoilage and remove any damaged pieces to prevent them from affecting the quality of the remaining stalks.
Can I eat the leaves of rhubarb?
No, the leaves of rhubarb should not be eaten, as they contain toxic compounds called oxalic acid and anthraquinone glycosides. Consuming these leaves can lead to serious health issues, including nausea, vomiting, and even more severe symptoms in high enough quantities. It is crucial to remove the leaves before preparing or consuming rhubarb stalks.
Only the stalks are safe to eat and are the parts commonly used in cooking and baking. Always ensure that you discard the leaves properly and keep them away from food preparation areas. This practice ensures safe handling and consumption of this unique and delicious plant.
