Coffee flash, also known as flash brewing or Japanese iced coffee, is a method of brewing coffee that involves slowly pouring hot water over ground coffee beans in a filter. This technique allows for a clean and balanced extraction of the coffee’s flavors and oils, resulting in a smooth and refreshing cup of coffee. In this article, we will explore the world of coffee flash, its benefits, and provide a step-by-step guide on how to make it at home.
What is Coffee Flash?
Coffee flash is a brewing method that originated in Japan and has gained popularity worldwide for its unique flavor profile and refreshing taste. Unlike traditional hot-brewed coffee, coffee flash is brewed using hot water, but the coffee is not steeped for a long time. Instead, the water is slowly poured over the coffee grounds in a filter, allowing for a quick and even extraction of the coffee’s flavors.
Benefits of Coffee Flash
There are several benefits to brewing coffee using the flash method:
- Smooth and balanced flavor: Coffee flash allows for a clean and balanced extraction of the coffee’s flavors and oils, resulting in a smooth and refreshing cup of coffee.

What is the ideal water temperature for brewing coffee?
The ideal water temperature for brewing coffee is between 195°F and 205°F. This temperature range allows for the optimal extraction of flavors and oils from the coffee grounds. If the water is too hot, it can burn the coffee, resulting in a bitter taste. On the other hand, if the water is too cold, it can lead to under-extraction, resulting in a weak or sour taste.
To achieve the ideal water temperature, you can use a thermometer to measure the temperature of the water. Alternatively, you can let the water boil and then let it cool for about 30 seconds to 1 minute before pouring it over the coffee grounds. This will help to bring the water temperature down to the ideal range.
How much coffee should I use for the perfect cup?
The amount of coffee to use for the perfect cup depends on several factors, including the brewing method, the type of coffee beans, and personal taste preferences. A general rule of thumb is to use 1 tablespoon of coffee for every 6 ounces of water. However, this ratio can be adjusted to suit your taste preferences. If you prefer a stronger cup of coffee, you can use more coffee, while if you prefer a weaker cup, you can use less.
It’s also important to note that the type of coffee beans can affect the flavor of the coffee. For example, Arabica beans tend to be more delicate and require a slightly lower coffee-to-water ratio, while Robusta beans are bolder and can handle a higher ratio. Experimenting with different coffee-to-water ratios and brewing methods can help you find the perfect balance for your taste preferences.
What is the best type of coffee beans for brewing?
The best type of coffee beans for brewing depends on personal taste preferences and the brewing method. Arabica beans are generally considered to be of higher quality and have a more delicate flavor, while Robusta beans are bolder and have a harsher flavor. Within these two main categories, there are many different sub-types of coffee beans, each with its own unique flavor profile.
When choosing a type of coffee bean, consider the flavor profile you prefer. If you like a smooth and balanced flavor, Arabica beans may be a good choice. If you prefer a bolder and more intense flavor, Robusta beans may be a better option. You can also experiment with different blends of coffee beans to find the perfect flavor for your taste preferences.
How do I store coffee beans to preserve freshness?
To preserve the freshness of coffee beans, it’s essential to store them properly. Coffee beans can absorb moisture and odors from the air, which can affect their flavor and aroma. To prevent this, store coffee beans in an airtight container in a cool, dry place. You can also store coffee beans in the freezer to preserve their freshness for a longer period.
When storing coffee beans, make sure to keep them away from direct sunlight, heat sources, and moisture. You can also use a coffee bean container with a one-way valve to allow carbon dioxide to escape while keeping air out. This will help to preserve the freshness of the coffee beans and prevent them from becoming stale.
What is the difference between light and dark roast coffee?
The main difference between light and dark roast coffee is the level of roasting, which affects the flavor and color of the coffee. Light roast coffee is roasted for a shorter period, which preserves more of the coffee’s natural acidity and flavor. Dark roast coffee, on the other hand, is roasted for a longer period, which brings out a richer and more bitter flavor.
The level of roasting can also affect the body and texture of the coffee. Light roast coffee tends to be more acidic and have a lighter body, while dark roast coffee is more bitter and has a heavier body. When choosing between light and dark roast coffee, consider your personal taste preferences and the brewing method. Light roast coffee is often preferred for pour-over and drip brewing, while dark roast coffee is often preferred for espresso and French press.
Can I use tap water to brew coffee?
While it’s possible to use tap water to brew coffee, it’s not always the best option. Tap water can contain impurities and minerals that can affect the flavor and quality of the coffee. For example, tap water with high levels of chlorine or minerals can give the coffee a bitter or unpleasant taste.
If you want to use tap water to brew coffee, it’s a good idea to use a water filter to remove impurities and minerals. You can also use a water purification system to improve the taste and quality of the tap water. Alternatively, you can use bottled or filtered water to brew coffee, which can provide a cleaner and more neutral flavor.
How often should I clean my coffee brewing equipment?
It’s essential to clean your coffee brewing equipment regularly to prevent the buildup of old coffee oils and residue. This can affect the flavor and quality of the coffee and also lead to the growth of mold and bacteria. The frequency of cleaning depends on how often you use the equipment and the type of equipment you have.
As a general rule, clean your coffee brewing equipment after every use to remove any leftover coffee grounds and oils. You can also descale your equipment every 3-6 months to remove mineral deposits and prevent corrosion. Regular cleaning and maintenance can help to extend the life of your equipment and ensure that your coffee always tastes its best.
