Each has its strengths, and both give you full control over your coffee quality at home.

2. FLASH BREW ICED COFFEE WITH HARIO V60
2.1 What Is Flash Brew?
Flash brew (or Japanese iced coffee) is brewed hot over ice. This rapid cooling locks in the coffee’s brightness and aroma, producing a clean, vibrant flavor. The V60 is perfect for this method due to its fast flow and even extraction.
2.2 Ingredients You’ll Need
- 20g of freshly ground coffee (medium-fine)
- 150g hot water (about 94°C)
- 100g ice
- Filtered water
- V60 dripper + paper filter
- Carafe or mug
- Scale and timer
2.3 Step-by-Step Instructions
- Place 100g of ice into your carafe.
- Set the V60 dripper and a pre-rinsed filter on top.
- Add 20g of ground coffee to the filter.
- Start your timer and bloom the coffee with 30g of hot water for 30 seconds.
- Slowly pour the remaining 120g of water in concentric circles over the next 2 minutes.
- Once the drip stops, swirl the coffee to melt the ice and mix.
- Serve over fresh ice if desired, and enjoy your crisp, aromatic flash brew.
3. COLD BREW WITH THE HARIO COLD BREW BOTTLE

The Hario Cold Brew Bottle is built for immersion brewing, which means you steep coffee grounds in cold water over several hours. It’s super simple, mess-free, and creates a smooth, mellow cold brew with low acidity.
3.2 Ingredients You’ll Need

- 700ml cold filtered water
- Hario Cold Brew Bottle
3.3 Brewing Instructions
- Add your ground coffee to the filter basket inside the bottle.
- Pour 700ml of cold filtered water into the bottle.
- Seal it and give it a gentle shake to saturate all the grounds.
- Place the bottle in the fridge for 8–12 hours.
- Remove the filter basket, and you’ve got cold brew ready to pour!
Optional: Serve over ice or with a splash of milk or flavored syrup (vanilla, caramel, etc.).
4. TIPS FOR BREWING COLD COFFEE LIKE A PRO
4.1 Use Fresh, High-Quality Beans
Cold coffee doesn’t mask flaws—it exposes them. Use freshly roasted beans with complex flavor profiles. African beans like Ethiopian Yirgacheffe or Kenyan AA are excellent for floral, fruity iced brews.
4.2 Grind Consistency Is Key
- For flash brew: Use a medium-fine grind (similar to table salt).
- For cold brew: Use a coarse grind (similar to sea salt).
Uniform grinds ensure proper extraction and eliminate bitterness or muddiness.
4.3 Filtered Water Makes a Difference
Your coffee is 98% water, so don’t use tap water if it tastes off. Go for filtered or spring water for a cleaner, purer cup.
4.4 Chill Your Equipment
If you’re making cold coffee, keep everything cold—your carafe, bottle, even your glass. This maintains brew temperature and flavor integrity.
4.5 Adjust Ratios to Taste
Want it stronger? Use more coffee or less water. Prefer a lighter brew? Do the opposite. Tweak the coffee-to-water ratio until it fits your flavor preferences.
5. COMPARING HARIO METHODS: FLASH BREW VS COLD BREW
