Learn how to make iced coffee at home, complete with the cold brew coffee concentrate and final mixture. Fashioned after the Tim Horton’s&trade iced coffee.

Cold Brewed Iced Coffee

So I set out to figure out how to make Tim Horton’s™ style iced coffee at home. And by gosh, I think I’ve come pretty darned close! Here’s how …

Ingredients and Substitutions

Coffee Grounds – use your favourite ground coffee brand.

Instant Dissolving Sugar – this is a super-fine sugar that will dissolve instantly in cold liquids. (Regular sugar won’t dissolve in cold liquids). Look for it in the sugar section at the grocery store or at Bulk Barn. If you can’t find it, you’ll have to substitute a sugar syrup, which involves heating regular sugar with water and then using the syrup to sweeten the iced coffee.

Recipe Tips

You can play around with the proportions of coffee concentrate and water to taste, as well as the amount of added cream and milk.

You may be surprised by the amount of sugar, but trust me, if you’re looking for a clone of Tim Horton’s™ Iced Coffee, you’ll need that much.

Cook Time: 5 minutes
Total Time: 15 minutes
Yield: 8 servings


For the coffee concentrate:

  • 32 oz cold water, (4 cups)
  • 1 cup ground coffee, (good quality coffee- anything you’d brew up to drink hot)

For the Iced Coffee:

  • 1/2 cup coffee concentrate, (from above)
  • 1/2 – 2/3 cup cold water
  • 2 teaspoons instant dissolving sugar, *See Note below
  • 1/4 cup half and half cream, 10% bf
  • 1/3 cup milk
  • 3 ice cubes


  • Make the coffee concentrate: Combine cold water and coffee grounds in a container. Stir to moisten all the grounds. Cover with plastic wrap and leave at room temperature to steep for 12-24 hours. Place a coffee filter into a wire strainer and strain, discarding grounds. Transfer coffee concentrate to a glass jar and refrigerate. It will keep for several weeks in the fridge (but it won't last that long ;)
  • To make an iced coffee: In a large glass, combine coffee concentrate, water, sugar, half and half and milk. Stir well. Add ice cubes and enjoy!
  • You can play around with the proportions of coffee concentrate to water, to taste. The 1/2 cup of water makes an iced coffee a little stronger but mellows out nicely as the ice melts. If you prefer it a little lighter, add the 2/3 cup of water or more from the start. The same goes for the added cream and milk. You can use as much or as little of both or either as you like, to your taste.
  • Note: *Instant dissolving sugar is available in the sugar section of most grocery stores or at most Bulk Barns and is a special sugar that is made to dissolve easily in cold liquids.
  • Note that regular sugar will not dissolve in cold liquids, so can’t be substituted as is. All is not lost though. Just make a simple syrup by bringing 1 cup water to a boil and adding 1 cup sugar and stirring until completely dissolved. Remove from heat, let cool and then store in a jar to add to your coffee as needed. (Can double or triple this recipe)
