Cold brew coffee has become a staple in many coffee lovers’ daily routines. Its smooth, rich flavor and low acidity make it a perfect choice for those who want to enjoy coffee without the bitterness. However, one question that often arises is: how long is cold brew good for? In this article, we will delve into the world of cold brew and explore its shelf life, storage methods, and signs of spoilage.
Understanding Cold Brew Coffee
Before we dive into the shelf life of cold brew, it’s essential to understand what cold brew coffee is and how it’s made. Cold brew coffee is a type of coffee that is brewed without heat. Instead of using hot water to extract the flavors and oils from the coffee beans, cold brew coffee uses cold water to steep the grounds for an extended period, usually 12-24 hours. This process results in a smooth, low-acidity coffee that is perfect for hot summer days or as a base for coffee cocktails.
The Factors That Affect Cold Brew’s Shelf Life
