Iced Coffee at Home: Guide and Machines [2026]

Iced Coffee at Home: The Complete Guide for Summer 2026

Summer is on its way, and with it the irresistible craving for cold coffee. You do not need an expensive machine: with the right techniques, you can make iced drinks at home that rival the best coffee shops. Here is our complete guide to mastering iced coffee, from slow-steeped cold brew to a quick espresso tonic.

Cold Brew or Iced Coffee: What Is the Difference?

Cold brew (cold steeping)

The coffee steeps in cold water for 12 to 24 hours. Without heat, the extraction is gentle and selective. The result is a low-acid coffee that is naturally sweet, with chocolatey and fruity notes.

Pros: smooth on the palate, low acidity, keeps for 5-7 days, versatile concentrate
Cons: needs planning ahead (made the day before), less body than an espresso

Iced coffee (espresso over ice)

A hot espresso (or a filter coffee) poured straight over ice. The heat extracts more acids and oils. The thermal shock from the ice locks in some aromas and sharpens others.

Pros: fast (2 min), bold, intense
Cons: more bitter, risk of dilution if the ice melts too quickly

Method 1: Homemade Cold Brew (Our Favorite)

Ingredients

• 100 g coarsely ground coffee
• 1 L cold water (filtered if possible)

Equipment

• French press or a Mason jar + filter

Steps

1. Mix the ground coffee and the cold water in a container
2. Let it steep for 12 to 24 hours in the refrigerator
3. Filter carefully (twice if needed)
4. Serve straight over ice, or dilute 1:1 with water or milk

Recommended ratio: 1 part coffee to 10 parts water. Adjust to taste.

Method 2: Espresso Tonic (The Refresher)

Ingredients

• 1 shot of espresso (30-40 ml)
• 150 ml of well-chilled tonic water
• Ice cubes
• 1 slice of lime

Steps

1. Fill a glass with ice cubes
2. Pour in the chilled tonic water
3. Gently add the hot espresso (it will foam)
4. Garnish with the lime
5. Drink immediately

The bitterness of the tonic and the brightness of the espresso make a surprising, addictive pairing.

Method 3: Homemade Iced Latte

Ingredients

• 1 shot of espresso (or 60 ml of strong coffee)
• 200 ml of cold milk
• Vanilla or caramel syrup (optional)
• Ice cubes

Steps

1. Pull the espresso and let it cool for 2 minutes
2. Pour the syrup into the glass and add the ice cubes
3. Pour in the cold milk
4. Add the espresso slowly to create layered tones
5. Stir before drinking

The Best Machines for Iced Coffee

Automatic machine with an Over Ice setting

Some automatic machines, like the De'Longhi Magnifica Evo or the Jura E8, offer a dedicated program that extracts the espresso at a slightly lower temperature and in a volume suited to tall glasses.

No machine? A French press is enough

A French press makes excellent cold brew. Mix coffee and cold water in the carafe, let it steep for 12 hours in the fridge, then press down slowly and pour.

Barista Tips for Great Iced Coffee

Coffee ice cubes

Freeze cold coffee in ice cube trays. They chill your drink without diluting it. Essential for iced coffee.

Milk ice cubes

Same idea, but with milk. As they melt, they enrich your iced latte instead of watering it down.

The shaker

Pour espresso, ice cubes, and syrup into a shaker. Shake for 10 seconds. The result: airy foam, the perfect temperature, a professional look.

Double-walled glasses

They keep drinks cold longer with no condensation. They transform both the look and the feel of the experience.
