Flash Brew Coffee: Une Méthode Innovante pour un Café Glacé Parfait

Flash Brew Coffee: An Innovative Method for Perfect Iced Coffee

Flash brew, also known as Japanese iced coffee, is a method of preparing iced coffee that is notable for its speed and ability to preserve the delicate flavors of the coffee beans. Developed in Japan in the 1960s, this technique has become popular around the world thanks to its refreshing and flavorful results.

What is Flash Brew?

Flash brewing involves brewing hot coffee directly over ice, allowing the coffee to be instantly cooled while retaining its bright, complex flavors. Unlike cold brew, which requires a long cold brew, flash brew uses hot water to quickly extract the flavors from the coffee beans before immediately chilling them over ice. This creates an iced drink that is less acidic and less bitter than traditional iced coffee.

The Benefits of Flash Brew

  • Preserved Flavor : Rapid cooling prevents oxidation and loss of volatile flavors, providing a fresher, more complex cup of iced coffee.
  • Speed : Unlike cold brew which can take 12 to 24 hours, flash brew is ready in just a few minutes, ideal for rushed mornings.
  • Flexibility : This method works well with a variety of coffee beans, particularly those with light to medium roasts that reveal fruity and floral notes.

James Hoffmann and Immersion for Flash Brew

James Hoffmann, a renowned coffee expert, recommends using immersion methods such as the Clever Dripper or Aeropress for flash brewing. These methods allow for a more controlled and uniform extraction, ensuring a better quality iced coffee.

How to Make a Flash Brew at Home

Necessary Equipment:

  • Aeropress or Clever Dripper
  • coffee grinder
  • Kitchen scale
  • Swan Spout Kettle
  • Ice
  • Filtered water

Preparation Steps:

  1. Grind Coffee Beans : Use a medium to medium-fine grind, similar to that used for filter coffee or pour-over.
  2. Prepare the Ice : Fill your carafe or coffee pot with ice. The amount of ice should be about half of the total volume of water used for the brew.
  3. Brew the Coffee :
    • With Aeropress :
      1. Place the ground coffee into the Aeropress.
      2. Add hot water (around 85-90°C) to the ground coffee, up to half of the Aeropress.
      3. Mix gently and let steep for 2 minutes. If you steep longer it's okay, it may improve the extraction.
      4. Press the coffee directly onto the ice.
    • With Clever Dripper :
      1. Place the ground coffee in the Clever Dripper.
      2. Add hot water to the ground coffee and let it steep for 6 minutes. Longer infusion may also be beneficial for optimal extraction.
      3. Place the Clever Dripper on a carafe filled with ice to filter the coffee.
  4. Stir and Serve : Once brewing is complete, stir the coffee well to ensure all the ice has melted and the coffee is thoroughly cooled. Serve immediately with additional ice cubes if desired.

Recipe Example:

For a 500 ml portion of flash brew:

  • 30 grams of ground coffee
  • 330 grams of hot water
  • 170 grams of ice

Additional Tips:

  • Use high quality coffee beans for the best results. Light to medium roast coffees with high acidity are particularly recommended.
  • Experiment with coffee and water ratios to adjust the strength of your coffee to your personal preference.

Comparison with Cold Brew

Cold brew is another popular method for making iced coffee, but it differs significantly from flash brew. Cold brew involves prolonged cold brewing, typically 12 to 24 hours, and produces a smooth, low-acid coffee. In contrast, flash brew uses hot water to quickly extract aromas and flavors before instantly cooling the coffee. Here are some key differences between the two methods:

Preparation time :

  • Cold Brew: 12-24 hours
  • Flash Brew: A few minutes

Flavor Profile:

  • Cold Brew: Mild, low acidity
  • Flash Brew: Lively, complex, more pronounced flavors

Extraction Method:

  • Cold Brew: Extended cold brew
  • Flash Brew: Fast hot brew, immediate cooling

Why Choose Flash Brew?

Flash brew is ideal for those looking for a quick and efficient method of brewing iced coffee without compromising quality and flavor. It also helps highlight the unique aromas of specialty coffee beans, providing a rich and refreshing taste experience.

Selection of Coffee Beans for Flash Brew

The choice of coffee beans is crucial for a good flash brew. Choose light to medium roasted beans to maximize delicate, fruity aromas. Specialty coffees from regions like Ethiopia, Kenya or Guatemala are particularly suitable because of their complex flavor profiles. On Jockos.coffee , here are some recommendations:

The Impact of Water and Temperature

Water makes up 98% of your cup of coffee, so using good quality water is essential. Use filtered water to avoid impurities and unwanted tastes. The water temperature should be around 85-90°C for the Aeropress or Clever Dripper. This temperature allows optimal extraction of aromas without burning the coffee.

Experimenting with Additives

Although flash brew is delicious on its own, it can also be customized with various additives. Add a little milk or cream for a richer texture, or stir in flavored syrups like vanilla or caramel for a touch of sweetness. Fans of taste experiments can even try herbs and spices, like cinnamon or cardamom, for added flavors.

Conclusion

Flash brew is an innovative and convenient coffee brewing method, ideal for those who want to enjoy an iced drink full of flavor without waiting for hours. Whether you're a coffee lover looking for new experiences or simply looking for a quick method to make iced coffee, flash brew offers a delicious and efficient solution.

By applying this information, you can enhance your caffeinated experience and discover the subtleties and unique flavors of your favorite coffee beans with this quick and effective method.
