DIY Cold Brew // Coffee & Tonic

DIY Cold Brew // Coffee & Tonic

Cold brew coffee can be super delicious, especially when it’s fresh. The best way to have it fresh on hand? DIY!

Drink cold brew on it’s own for a super-charged cold drink, use as an ingredient in cocktail, or dilute with tonic to make the incredibly refreshing Coffee & Tonic (trust us).

That recipe is below.

Cold Brew Concentrate 

Makes 1L of delicious Cold Brew Coffee 

What you’ll need:

  1. 90g of DETOUR Coffee (we recommend any espresso profile - see below)
  2. 1L of filtered cold water
  3. Mason Jar or Food Safe Container


  1. Grind 90g of coffee on a medium setting. Similar to a pour over grind setting, or about the size of table sugar granules.
  2. Add the coffee to the container and fill with cold or room temperature water until full (use a container with little to no head space - oxygen is the enemy of coffee).
  3. Stir to wet all the grinds.  Cover and place in the fridge.
  4. After 24 hours of brewing, pour through cheesecloth or a paper coffee filter.
  5. Store in an airtight container in the fridge for up to 3 days.

  3. Finish by slowly adding in the cold brew

Happy Brewing!
