Cold Brew: The Coffee That Makes Itself (Seasonal Hit)
When the thermometer shows above 25°C (77°F), the last thing you dream about is a steaming cup of espresso. This is where Cold Brew takes the stage – a drink that in the last few years has moved from a niche curiosity to the absolute king of summer cafes.
This isn't just regular "iced coffee" (meaning hot coffee over ice). This is a drink where time replaces temperature, extracting the sweetest notes from the bean and leaving the bitterness far behind.
Quick Recipe: Homemade Cold Brew (Ready-to-Drink)
The best part about Cold Brew? You make it in the evening, and in the morning, you have ready fuel for the whole day.
| Parameter | Value |
|---|---|
| Coffee | 60–70g per every 1000ml (1 liter) of water |
| Grind | Very coarse (like coarse sea salt, zero dust) |
| Water | Cold, filtered |
| Steeping time | 12 to 18 hours in the fridge |

The Magic of Low Temperature
Why does Cold Brew taste so different? Hot water instantly dissolves the acids and oils contained in the coffee, but in the process, it also washes out the compounds responsible for bitterness. Cold water treats the bean much more gently – this process is called maceration.
The result? A drink with very low acidity, almost completely lacking bitterness, yet full of notes of chocolate, caramel, and ripe fruit. Important for energy fans: Cold Brew usually has a higher caffeine content than a classic "black coffee" because the long contact between water and coffee allows for its almost complete extraction.
Instructions: Cold Brew in 4 Steps
You don't need expensive accessories. A jar, a scale, and any coffee filter will do.
1. Grind and Pour
Pour coarsely ground coffee into a large jar, bottle, or carafe. Pour in cold, filtered water.
2. Stir and Secure
Stir gently to make sure every coffee particle has contact with the water. Screw the vessel's cap on tightly. Important: Coffee absorbs smells like a sponge, so make sure it isn't standing next to an open container of leftovers in the fridge.
3. Patience (12–18h)
Put the jar in the fridge. The optimal time is about 14-16 hours. After 20-24 hours, the coffee can start taking on unpleasant, "woody" and earthy notes, so it's worth keeping an eye on the time.
4. Filtering (The Key to Clarity)
Pour the contents through a paper filter (e.g., for a V60 or a standard drip coffee filter). This will remove coffee particles and sediment, making the drink clear and light like tea.
Serving: What to drink it with?
Your Cold Brew is ready to drink immediately after filtering, but the real fun begins with additions:
- Black & Cold: Just ice. This allows you to appreciate the bean's profile.
- White: Oat or pea milk – their natural sweetness complements "cold coffee" brilliantly.
- Coffee Tonic: An absolute hit – fill a glass with ice, pour 1/2 Cold Brew, 1/2 good tonic, and add a slice of orange and a sprig of rosemary.
Which coffee to choose?
Cold Brew is very forgiving, but specialty beans take it to another level:
- Classic (Chocolatey): Choose beans from Brazil, Guatemala, or El Salvador. You will get a drink that tastes like a liquid praline.
- Fruity (Refreshing): Choose light roasts from Ethiopia or Kenya. The Cold Brew will taste like blueberry compote or peach iced tea.
Troubleshooting: What went wrong?
- Coffee is cloudy? The filter was likely too porous or the grind too fine. Try double filtering through paper.
- Tastes flat and boring? Try macerating at room temperature for the first 2 hours, and only then put the jar in the fridge.
- Is it too weak? Add more coffee (e.g., 80g/1l), creating a concentrate that you can dilute with water or milk before serving.
Summary
Cold Brew is proof that in the coffee world, patience is rewarded. It's the perfect method for the busy – once filtered, the brew can be stored in the fridge for up to 5-7 days. Make a batch on Sunday evening and have ready refreshment for the whole week.
