We’ll need:

Coarse Ground Coffee
Cold water
And InstaCuppa Thermos Steel Water Bottle

Procedure:

1. Take off the infuser rod from the bottle.
2. Put 1-2 tbsp or more of coarse ground coffee inside the infusion rod.
3. Cover the infusion rod back.
4. Lock the rod in the bottle.
5. Fill with cold water.
6. Cover the bottle back.
7. Let the coffee steep overnight, or for at least 12 hours. During this time, the coffee slowly infuses into the water for stronger and concentrated brew.
