What Is Hario Cold Brew?
Cold brew coffee is a popular alternative to traditional hot-brewed coffee, known for its smooth, less acidic, and naturally sweet flavor. Unlike iced coffee, which is made by brewing hot coffee and then cooling it down, cold brew is made by steeping coarsely ground coffee in cold or room temperature water for an extended period of time.
Using Hario equipment for cold brew offers distinct advantages. Known for their precision and high-quality design, Hario products, particularly their cold brew bottles and pots, ensure optimal brewing conditions. The Hario cold brew system allows for easy brewing with consistent results, producing a full-bodied, rich coffee that is perfect for hot summer days or as a base for various coffee drinks.
Ingredients and Equipment
Ingredients
Coarsely Ground Coffee: The type of coffee you choose will affect the flavor profile of your cold brew. You can use any coffee, but beans that are medium to dark roast often work best for cold brew as they offer a smoother, more balanced taste.
Filtered Water: Always use filtered water to ensure the best taste. The quality of water plays a significant role in the flavor of your cold brew.
Equipment
Hario Cold Brew Pot or Bottle: This is the main equipment for brewing your cold brew. Hario offers several models, including the Hario Mizudashi Cold Brew Pot, which is highly recommended for its ease of use and consistent results.
Coffee Grinder: A burr grinder is best for achieving the ideal coarse grind for cold brew coffee. A uniform grind ensures proper extraction without over-extraction or bitterness.
Measuring Spoon or Scale: A scale is helpful for accuracy, but a measuring spoon can work in a pinch to ensure the correct coffee-to-water ratio.
Stirring Spoon or Paddle: This is useful for mixing the coffee grounds with water for even saturation.
Refrigerator: The refrigerator is where your cold brew will steep for the required brewing time.
Fine Mesh Strainer or Cheesecloth: These tools are used for filtering out the coffee grounds after steeping.
Step-by-Step Instructions
Making Hario cold brew coffee is simple. Follow these easy steps to create a delicious and refreshing cold brew:
1. Measure Your Coffee Grounds
Start by measuring the coffee grounds for your cold brew. The standard ratio is 1:4 for coffee-to-water, but you can adjust this based on your preferences for a stronger or milder brew.
For example:
For a standard batch: Use 60 grams of coarsely ground coffee for 240 milliliters of water (for Hario cold brew pots).
For a stronger brew: Increase the amount of coffee to 70-80 grams per 240 milliliters of water.
2. Grind Your Coffee Beans
Use a burr grinder to achieve a coarse grind. The grind should be similar to that used for French press brewing. Fine grinds will result in a cloudy, bitter brew, so make sure the grind is coarse.
3. Add Coffee Grounds to the Cold Brew Pot
Place your coarsely ground coffee into the Hario cold brew pot or bottle. Evenly distribute the grounds across the bottom for a uniform steeping process.
4. Pour in Filtered Water
Slowly pour the filtered water over the coffee grounds. Stir gently to ensure that all the grounds are fully saturated. This helps avoid uneven extraction.
5. Seal and Refrigerate
After mixing, seal the Hario cold brew pot or bottle. Place it in the refrigerator to steep. You will need to leave it for about 12-24 hours, depending on your desired strength.
Brewing Time and Temperature
Optimal Brewing Time
Cold brew coffee requires patience. The optimal steeping time is 12 to 24 hours. The longer the coffee steeps, the stronger and more robust the flavor will be. For a balanced brew, aim for 16-18 hours of steeping in the refrigerator.
Temperature Considerations
Cold brew is brewed at room temperature or cold temperatures. It’s crucial to keep the brew in the refrigerator to prevent any unwanted fermentation or off-flavors. The cold temperature helps extract the coffee oils slowly, resulting in a smoother taste.
Coffee-to-Water Ratio
The right coffee-to-water ratio is essential for achieving a balanced and flavorful cold brew. The general recommendation is a 1:4 ratio for a standard brew, but you can adjust this based on how strong or weak you want your coffee.
For a stronger cold brew, you may want to use a ratio of 1:3 or even 1:2 for a more concentrated taste. Conversely, if you prefer a milder flavor, 1:5 or 1:6 may work better.
Flavor Adjustments
While the cold brew process brings out naturally smooth flavors, there are a few ways to adjust the brew for a custom taste:
Strength
Stronger Coffee: Add more coffee grounds to your Hario pot or bottle. Increasing the coffee grounds by 10-20% will yield a stronger, more robust brew.
Weaker Coffee: If you find the cold brew too strong, dilute the coffee with more water after brewing, or use less coffee grounds initially.
Steeping Time
Longer Steep: For more intense flavors and higher caffeine content, steep your cold brew for 18-24 hours.
Shorter Steep: A quicker brew (12-14 hours) will be lighter and less concentrated.
Serving Suggestions
Once your cold brew has finished steeping, it’s time to serve it!
Dilution
Cold brew concentrate can be strong, so consider diluting it with water or milk to suit your taste.
Water: Add water in a 1:1 ratio for a milder brew.
Milk or Cream: Add milk, half-and-half, or even a splash of cream for a richer, smoother cup. You can use regular dairy or plant-based milk, such as almond, oat, or soy milk.
Ice
Serve your cold brew over ice for an extra refreshing experience. If the cold brew is too strong, ice will also help to dilute it slightly.
Sweeteners
If you prefer sweeter cold brew, consider adding sugar, honey, or flavored syrups. For a more decadent option, flavored creamers can also work.
Storage Tips
Cold brew coffee can be stored in the refrigerator for up to 1 week. However, for the best taste, it’s recommended to consume it within 3-5 days to ensure freshness.
To store, simply pour the cold brew into an airtight container or bottle. Ensure that the container is clean to prevent contamination and spoilage.
Common Mistakes and Troubleshooting
Mistakes
Too Fine a Grind: Using finely ground coffee will result in over-extraction, leading to a bitter and cloudy brew. Stick to a coarse grind.
Not Stirring the Grounds: If the grounds aren’t evenly saturated with water, you may experience uneven extraction, resulting in an unbalanced flavor.
Over-Steeping: Leaving the coffee to steep too long can cause over-extraction, making the brew too bitter. 18 hours is usually the ideal time.
Incorrect Coffee-to-Water Ratio: Too much coffee can make the brew too strong and bitter, while too little coffee can make it watery and weak.
Troubleshooting Tips
If your brew tastes too bitter, reduce the steeping time next time.
If your brew is too weak, increase the amount of coffee grounds or steep for longer.
If the brew is too acidic, try using a different coffee bean or adjust the coffee-to-water ratio.
