How to Make New Orleans Iced Coffee at Home

If you’ve ever wondered how to make the rich, slightly bitter, and deeply aromatic coffee served in classic New Orleans diners, the answer lies in a centuries-old blend of coffee and chicory — steeped cold for maximum smoothness. This isn’t just any iced coffee; it’s a New Orleans staple, where coffee meets chicory, sugar, and milk in a uniquely balanced way.

To make authentic New Orleans iced coffee, combine 40g of chicory powder with your coffee grounds, pour over 2.7 litres of ice water, steep for 8–12 hours, then add 85ml of sugar syrup before serving over ice and milk. That’s the full method in one line — but read on to master every detail.

What Is New Orleans Iced Coffee?

New Orleans iced coffee is a cold-brewed coffee blend traditionally made with roasted coffee beans and roasted chicory root. Unlike regular iced coffee, it includes chicory for depth, bitterness, and colour — a practice dating back to coffee shortages in the 19th century. The coffee is steeped in cold water for many hours, resulting in a smooth, low-acidity brew that’s then sweetened with syrup and mixed with milk.

Why Add Chicory to Coffee?

Chicory root is roasted, ground, and added to coffee for several reasons: it enhances aroma, deepens colour, boosts bitterness, and adds a woody, slightly nutty flavour. In New Orleans, it’s also a historical substitute or enhancer — used during coffee shortages and embraced for its unique profile. Locals often prefer it for its strong, bold character that stands up well to milk and sugar.

What You’ll Need to Make It

• Coffee grounds (amount not specified, but typically 1 part coffee to 16–20 parts water)
• Chicory powder: approximately 40g
• Ice water: 2.7 litres (2700ml)
• Sugar syrup: around 85ml (adjust to taste)
• Milk: equal parts to coffee liquid when serving
• Ice cubes
• A large pot or jar for brewing
• A filter or fine strainer for separation

Step-by-Step: Brewing New Orleans Iced Coffee

1. Combine Coffee, Chicory, and Ice Water

In a saucepan or large jar, mix your ground coffee (quantity unspecified in source but implied as standard cold brew amount) with 40g of chicory powder. Pour in 2.7 litres of ice water. Use a stirring tool to ensure even saturation.

2. Steep Cold for 8–12 Hours

Stir the mixture once more, cover it, and let it rest at room temperature or in a cool spot for 8 to 12 hours. This cold steep extracts flavours gently, avoiding bitterness while allowing the chicory and coffee to meld.

3. Filter the Brew

After steeping, strain the mixture through a filter or fine sieve to separate the liquid. The resulting brew should resemble a dark, smooth concentrated coffee — free of grounds and ready for sweetening.

4. Add Sugar Syrup

Stir in approximately 85ml of sugar syrup to the filtered coffee. Adjust quantity based on your preferred level of sweetness. The syrup integrates fully, balancing the chicory’s bitterness.

5. Serve Over Ice and Milk

Pour the sweetened coffee over ice, then add milk. The recommended ratio is roughly equal parts coffee and milk — similar to a café au lait with ice. The result is a smooth, refreshing, bold iced drink with deep flavour layers.

How Long Does It Last?

The filtered coffee concentrate keeps well for 5–7 days when refrigerated without additives. Once you add sugar, shelf life drops to 1–2 days. After mixing in both sugar and milk, consume within about 1 hour for best quality and freshness.

Flavour Profile & Characteristics

This coffee style is bold, slightly bitter, and full-bodied due to the chicory. The cold brew method ensures a smoother, less acidic cup compared to hot-brewed alternatives. The addition of sugar and milk rounds it out, creating a dessert-like yet balanced iced drink. Expect notes of dark roast, earthiness from chicory, and a creamy mouthfeel when milk is added.

Can You Adjust the Recipe?

Yes. The coffee-to-water ratio, chicory amount, and sweetness are all flexible. If you prefer a lighter chicory taste, reduce the 40g to 20–30g. For less sweetness, cut the sugar syrup to 50–70ml. Adjust milk ratios to taste, though equal parts coffee and milk is traditional.

What Grind Size Works Best?

While the source doesn’t specify, cold brew generally uses a coarse to medium-coarse grind — similar to what would pass through a China-standard No. 20 sieve at around 75% rate. A finer grind can lead to over-extraction or clogging during filtering, especially with the added chicory.

Why Cold Brew Instead of Hot Brew?

Cold brewing extracts fewer acids and bitter compounds, resulting in a smoother, less harsh cup — essential when combining with chicory, which can be intense. The long steep time allows for full flavour development without high heat, making it ideal for this style.

Frequently Asked Questions

What is chicory and why is it used in New Orleans coffee?

Chicory is the roasted and ground root of the chicory plant. It’s added to coffee for its bold, earthy flavour, darker colour, and enhanced bitterness. In New Orleans, it’s traditionally used to stretch coffee supplies, add richness, and create a signature taste profile that’s beloved locally.

How much chicory should I use in New Orleans iced coffee?

The article specifies using about 40g of chicory powder alongside the coffee grounds. You can adjust this amount based on taste, reducing to around 20–30g if you want a milder chicory flavour.

Can I use hot-brewed coffee instead of cold brewing for this recipe?

No, this recipe relies on cold brewing — steeping coffee and chicory in ice water for 8–12 hours. Hot brewing would change the extraction profile, likely increasing bitterness and acidity, and would not replicate the smooth, low-acid character of traditional New Orleans iced coffee.

What’s the best way to filter the coffee-chicory mixture?

Use a fine mesh sieve, coffee filter, or a dedicated cold brew filter. The mixture is thick with grounds and chicory, so ensure your filter can handle fine particles to get a clean, smooth coffee liquid.

How should I store leftover New Orleans iced coffee?

Store the filtered coffee concentrate in the fridge without sugar or milk for 5–7 days. Once sugar is added, keep it for only 1–2 days. Avoid adding milk until serving, as the mixture spoils quickly — use within about 1 hour once milk is added.

Is it necessary to use sugar syrup? Can I use plain sugar?

Sugar syrup is recommended because it dissolves easily in cold coffee. You could use plain sugar, but it may not dissolve fully unless the coffee is heated or the sugar is pre-dissolved in a small amount of hot water first.
