Irish Cold Brew is a refreshing and smooth coffee cocktail that combines cold brew coffee, Irish whiskey, and a touch of sweetness. This drink is a modern twist on the classic Irish Coffee, offering a chilled, energizing, and slightly boozy experience—perfect for warm evenings or brunch gatherings.
Unlike traditional Irish Coffee, which is served hot with whipped cream, Irish Cold Brew is served over ice, making it a lighter yet bold alternative. The combination of cold brew’s smooth taste and the rich complexity of Irish whiskey creates a balanced and sophisticated drink.

Step-by-Step Guide to Making Irish Cold Brew
Step 1: Brew the Cold Brew Coffee
✔ Combine 1 cup (100g) of coarsely ground coffee with 4 cups (1 liter) of cold water in a French press or jar.
✔ Stir gently and let it steep in the fridge for 12-24 hours.
✔ Strain the coffee through a fine mesh strainer or coffee filter to remove grounds.
✔ Tip: The longer the steep, the stronger and smoother the coffee will be.
Step 2: Mix the Whiskey and Sweetener
✔ Fill a tall glass with ice.
✔ Pour 1.5 oz (45ml) of Irish whiskey over the ice.
✔ Add ½ oz (15ml) of simple syrup or brown sugar syrup and stir well.
✔ Tip: Adjust the sweetness based on your preference.
Step 3: Add the Cold Brew Coffee
✔ Pour 4 oz (120ml) of cold brew coffee into the glass.
✔ Stir gently to mix the whiskey and coffee.
✔ Tip: If you prefer a stronger drink, use less cold brew and more whiskey.
Step 4: Optional – Add Cream for a Smooth Finish
✔ For a creamy version, gently pour 1 oz (30ml) of heavy cream or Baileys Irish Cream over the drink.
✔ Stir lightly or leave it layered for a beautiful presentation.
✔ Tip: Use a spoon to pour the cream slowly for a layered effect.
