Alternative Brewing Options

Cold Brew Coffee

Cold brew coffee is a great alternative to hot coffee, especially if you plan to store it in the refrigerator. Cold brew is created by steeping coarsely ground coffee beans in cold water for an extended period, usually 12-24 hours. This brewing process produces a smooth, less acidic, and highly concentrated coffee that can be stored in the fridge without compromising taste or quality.

To make cold brew coffee, simply combine coffee grounds and cold water in a jar or container, stirring to ensure the grounds are fully immersed. Cover and let it sit at room temperature or in the refrigerator for the desired timeframe. Once the brewing time has passed, strain the mixture through a fine-mesh sieve or cheesecloth to remove the grounds. The resulting liquid can be diluted with water or milk to achieve the desired strength and flavor. Enjoy your fresh cup of cold brew coffee straight from the fridge!


French Press Technique

Another popular method for making a delicious cup of coffee that can be stored in the refrigerator is the French press technique. The French press is a manual brewing process that allows for optimal extraction of flavors, resulting in a rich, full-bodied coffee.

To use a French press, start by heating water to around 200°F, or just below boiling. While the water is heating, add coarsely ground coffee to the French press carafe. Once the water has reached the appropriate temperature, pour it over the coffee grounds, ensuring they are fully saturated. Place the lid onto the carafe, but do not press the plunger yet. Let the coffee steep for 4 minutes, then slowly press the plunger down, separating the grounds from the liquid.

The French press brewed coffee can be poured into a container and stored in the fridge for later consumption. Simply reheat the desired amount in a microwave or on the stovetop before enjoying, or serve it over ice for a refreshing iced coffee.
