What is Cold Brew?

Contrary to popular belief, cold brew is not the same thing as a cup of cold coffee with a few ice cubes tossed in. Cold brew is a brewing process for coffee that involves steeping coarsely ground coffee beans in room-temperature water for an extended period, typically 12-24 hours. This slow extraction process results in a smooth taste and less acidic coffee concentrate that is often diluted with water or milk before serving. Cold brew is known for its rich flavor and low acidity, making it a popular choice for coffee lovers!

An iced coffee drink is exactly what it sounds like; drip coffee made with hot water and poured over ice. 

How to Make Cold-Brewed Coffee at Home

I find that the best way to make cold brew at home is to use a good ol’ French press. Here’s how:

  1. Use a coffee grinder to coarsely grind your coffee beans. Aiming for a coarse grind will prevent the coffee from taking on a bitter taste.
  2. Add the coarse coffee grounds to the French press. Use a ratio of around 1 part coffee to 4 parts water, depending on your taste preferences.
  3. Pour cold or room temperature water over the coffee grounds, ensuring that all the grounds are fully saturated.
  4. Stir the mixture gently to ensure even saturation.
  5. Place the plunger on top of the French press but do not press it down.
  6. For best results, let the coffee steep in the French press for about 12-24 hours at room temperature and away from any heat source.
  7. After steeping, slowly press down the plunger to separate the grounds from the liquid.
  8. Pour the cold brew concentrate into a separate container for storage. Keep stored in the refrigerator. 
  9. Dilute the concentrate with water or milk to your desired strength before serving.

For exact measurements use: one oz of coffee grounds and one cup of water. The best part about learning how to make your own cold brew is not having to wait in line at coffee shops to get your caffeine fix.

Microwave Method

Using a microwave oven is by far the quickest and easiest way to heat up your cold brew. Here’s how to do it:

  1. Pour your desired amount of cold brew coffee into a microwave-safe mug. Add desired amount of water or milk for dilution. Make sure to leave some space at the top to prevent spillage.
  2. Place the mug in the microwave and heat it on high power for about 30 seconds to 1 minute, depending on your microwave’s wattage and the desired temperature.
  3. Carefully remove the hot mug from the microwave using oven mitts or a towel.
  4. Give the coffee a quick stir to ensure that it’s evenly heated.
  5. If it’s not hot enough, you can continue to heat it in short intervals, checking the temperature after each interval until it reaches your desired warmth.

Stovetop Method

Heating cold brew coffee on the stove top allows you to control the temperature more precisely compared to using a microwave, giving you a more smooth flavor and more consistent result. Here’s how to do it: 

  1. Pour your desired amount of cold brew concentrate and water into a small saucepan or pot.
  2. Place the saucepan or pot on the stove over medium heat.
  3. Heat the cold brew coffee, stirring occasionally, until it reaches your desired temperature. Be careful not to let it boil, as this can cause it to develop a burnt taste. 
  4. Once heated to your liking, remove the saucepan or pot from the heat.
  5. Pour the hot cold brew coffee into a mug or cup using a strainer if necessary to catch any grounds that may have settled.
