Starbucks cold brewcoffee can remain fresh in the refrigerator for up to two weeks when stored properly. For optimal flavor, it's recommended to consume it within the first week.

Factors That Affect the Shelf Life of Cold Brew Coffee

• Storage Conditions: Cold brew coffee should be kept in airtight containers. Exposure to air can cause it to spoil more quickly, so it’s important to seal it tightly and store it in the refrigerator to maintain its freshness.
• Temperature: Cold brew coffee should be stored at a consistent, cold temperature. Refrigeration slows the growth of bacteria and helps preserve the flavor for a longer time.
• Exposure to Air and Light: Air and light can cause cold brew coffee to lose its flavor. It’s best to store cold brew in opaque, airtight containers and keep it in a dark place to maintain its taste.
• Additives and Ingredients: Adding milk, cream, or sweeteners can shorten the shelf life of cold brew coffee. These ingredients can spoil more quickly than the cold brew itself, so it’s recommended to add them just before drinking.

How Long Starbucks Cold Brew Lasts in the Fridge

For optimal freshness:

• Seal it well: Always store your cold brew in an airtight container to prevent it from losing flavor due to exposure to air.
• Keep it cold: Store it in the fridge immediately after purchasing and ensure it remains chilled until you're ready to drink it.
• Avoid light and heat: Store your cold brew in a cool, dark place, such as the back of the fridge, to keep it fresh.

If you add milk or cream to your cold brew, it is best to consume it within 8 hours, as dairy can spoil more quickly.

Signs That Your Cold Brew Has Gone Bad

Here are the signs that your cold brew coffee has gone bad:

• Mold: If you spot mold on the surface or inside the container, it’s time to throw it out.
• Unpleasant Smell: A sour or unpleasant odor is a strong indicator that your cold brew has spoiled. Fresh cold brew should have a mild, sweet scent.
• Off Taste: If the cold brew tastes sour, bitter, or unusual, it’s better to discard it.
• Change in Color: A cloudy or drastic change in color could mean the cold brew is no longer good.
• Loss of Aroma: If it no longer has its typical coffee aroma, it may have lost its freshness.

How to Extend the Freshness of Starbucks Cold Brew

• Use an Airtight Container: Store your cold brew in a container that seals tightly. This prevents air from getting in, which can cause the coffee to lose its taste and freshness.
• Keep It Covered: Always keep the lid on your cold brew container. This helps keep out contaminants and preserves the coffee's quality.
• Avoid Adding Milk or Cream: If you plan to store cold brew for a while, it's best to keep milk or cream separate. Adding these can shorten the coffee's shelf life.
• Consume Within Two Weeks: For the best taste, drink your cold brew within two weeks of making or buying it. After this time, the flavor may start to decline.

Best Practices for Storing Cold Brew Coffee in the Fridge

Choose Glass Containers: Glass is a good choice because it doesn't affect the coffee's flavor. Avoid plastic, as it can absorb and release odors that may alter the taste.

Refrigerate Immediately: After brewing, place your cold brew in the refrigerator right away. This helps slow down the process that can make it taste stale.
