How Long Do Sultanas Last?
Shelf Life and Storage Tips
Sultanas, also known as golden raisins (how long do raisins last?), are dried white grapes that have become a staple in pantries around the world. They are prized for their sweet flavor and versatility, commonly used in baking, cooking, and as snacks. The preservation process that turns grapes into sultanas naturally extends their shelf life by removing most of the water content, which inhibits the growth of microorganisms. As a result, sultanas have a significantly longer shelf life than fresh fruit.
The longevity of sultanas depends on proper storage conditions. When kept in a cool, dry place, sealed and protected from moisture and pests, unopened sultanas can be expected to maintain their quality for up to six months. Opened sultanas stored in the pantry can generally last for approximately three to five months. To further extend their lifespan, sultanas can be refrigerated, where they can maintain quality for nine to twelve months.
For long-term storage, sultanas may be frozen, which can extend their usability for over a year. It is essential to store them in an airtight container or freezer bag to prevent freezer burn and oxidation. While frozen sultanas can remain safe to consume for an extended period, slight changes in texture may occur once thawed. Despite these robust storage options, consumers should always check for signs of spoilage, such as mold or off odors, before using sultanas in their recipes.
What are Sultanas?
Sultanas are widely enjoyed for their sweet taste and versatility in culinary uses. Originating from certain varieties of seedless grapes, these dried fruits hold an important place in cuisines around the world.
Definition and Origin
Sultanas are a type of dried grape, traditionally made from seedless white grapes, specifically the Thompson Seedless grape variety. Originating from the Ottoman Empire, modern-day Turkey, they have become popular worldwide and are also extensively produced in Australia. Sultanas are known for their golden color and tend to be sweeter, softer, and juicier than their close relatives, raisins.
Types and Varieties
While sultanas are primarily derived from the Thompson Seedless grapes, variations exist due to different grape varieties and processing methods:
Golden Raisins: Often confused with sultanas, golden raisins are also made from seedless grapes but differ in color and processing. They are usually treated with sulfur dioxide to preserve their light color.
Regional Varieties: Different countries have their own preferred varieties of seedless grapes used to produce sultanas. From the traditional Turkish to the Australian sultanas, the climate and soil conditions impact the fruit's flavor and texture.

Comparison to Other Dried Fruits
When discussing shelf life, it is essential to understand how sultanas compare to other dried fruits like raisins and currants, as each has unique characteristics that can affect longevity.
Sultanas vs. Raisins
Sultanas are a type of dried fruit made from seedless white grapes, usually of the Thompson Seedless variety. They are often lighter in color compared to raisins, which are also dried grapes but typically from darker grape varieties. When stored properly in a cool, dry place, sultanas can last just as long as raisins, which is approximately 6 months to a year past their printed date when unopened. However, raisins may have a slightly longer shelf life due to their darker skin and less moisture content.
Color: Lighter (sultanas) vs Darker (raisins)
Grape Variety: White (sultanas) vs Mixed/Dark (raisins)
Shelf Life: Comparable, with raisins potentially lasting slightly longer
Sultanas vs. Currants
Currants, on the other hand, are a completely different fruit when referred to in the context of fresh produce, being small berries from the ribes family. However, when speaking of dried currants (often labeled as Zante currants in the United States), they're actually tiny, dried red grapes from a variety known as Black Corinth or Carina, originated from Greece. Currants tend to be smaller and less juicy than sultanas, with a stronger and tangier flavor. Their reduced size and lower moisture content may lend dried currants a marginally longer shelf life compared to sultanas, but they generally follow the same storage guidelines for optimal freshness.
Type: Dried berry/grape (currants) vs Dried grape (sultanas)
Taste: Tangier (currants) vs Sweeter Taste (sultanas)
Shelf Life: Similar, with currants potentially lasting slightly longer due to low moisture
