Cold brew coffee has become a staple in many coffee lovers’ lives, and for good reason. Its smooth, low-acidity flavor and refreshing taste make it a perfect pick-me-up for hot summer days. However, one question that often arises among cold brew enthusiasts is: how long can you keep cold brew in the fridge? In this article, we’ll delve into the world of cold brew coffee and explore the factors that affect its shelf life, as well as provide some tips on how to store it properly.
Understanding Cold Brew Coffee
Before we dive into the topic of shelf life, let’s take a brief look at what cold brew coffee is and how it’s made. Cold brew coffee is a type of coffee that’s brewed without heat. Instead of using hot water to extract the flavors and oils from the coffee beans, cold brew coffee is made by steeping coarse-ground coffee beans in cold water for an extended period of time, usually 12-24 hours. This process results in a smooth, low-acidity coffee concentrate that can be diluted with water or milk to create a refreshing drink.
The Factors That Affect Cold Brew’s Shelf Life
Several factors can affect the shelf life of cold brew coffee, including:
- Storage conditions: Cold brew coffee should be stored in the fridge at a temperature of 40°F (4°C) or below. If it’s stored at room temperature, it can become contaminated with bacteria and mold, which can affect its flavor and safety.
- Container quality: The type of container used to store cold brew coffee can also affect its shelf life. Glass or stainless steel containers are best, as they don’t impart any flavors or odors to the coffee. Plastic containers, on the other hand, can leach chemicals into the coffee, affecting its flavor and safety.
- Coffee-to-water ratio: The ratio of coffee to water used to make the cold brew can also affect its shelf life. A higher coffee-to-water ratio can result in a more concentrated coffee that’s more prone to spoilage.
- Handling and hygiene: How the cold brew is handled and stored can also affect its shelf life. If the container is not properly sealed or if the coffee is not handled hygienically, it can become contaminated with bacteria and mold.
The Shelf Life of Cold Brew Coffee
So, how long can you keep cold brew in the fridge? The answer depends on several factors, including the storage conditions, container quality, coffee-to-water ratio, and handling and hygiene.
- Homemade cold brew: If you make your own cold brew at home, it’s generally recommended to consume it within 7-10 days. This is because homemade cold brew is more prone to contamination and spoilage due to the lack of preservatives and proper packaging.
- Store-bought cold brew: Store-bought cold brew, on the other hand, can last longer due to the use of preservatives and proper packaging. It’s generally recommended to consume store-bought cold brew within 2-3 weeks.
Signs of Spoilage
So, how do you know if your cold brew has gone bad? Here are some signs of spoilage to look out for:
- Off smell: If your cold brew smells sour or unpleasantly sweet, it may be a sign that it’s gone bad.
- Slime or mold: If you notice any slime or mold on the surface of the coffee or on the container, it’s a sign that the coffee has become contaminated.
- Slimy texture: If the coffee has a slimy texture or has separated into layers, it may be a sign that it’s gone bad.
