Water Prep

1. Heat your water to 200F (just off boil).

2. Unfold your filter and place in your Chemex. If using the square filters, the triple-fold side should be facing the spout.

3. Clean your filter with warm water. Let it warm up your Chemex and then discard.

2. Pour your ground coffee into the filter and gently shake it so it’s level.

The Best Chemex Pour Over

Use continual circular motions, starting in the centre, working your way to the edge of the coffee and then back in. Try not to pour water onto the filter itself.

Start your timer

0 – 15s: Pour 150g of water over the coffee grounds.

15s – 45s: The 30 second bloom. Smell the delicious aroma as the coffee bubbles and moves.

0.45s – 2.30m: Pour 300g of water. Wait for it to drain enough for you to repeat. Pour the remaining 250g of water.

2.30m – 4m: Let the water drain through. You will have a 700g yield in total.


Serve and Enjoy

Your Chemex should be filled up to near the nipple on the front (approximately 20 oz of brewed coffee).

Take your filter out and let it drain into the sink. Discard appropriately.
Swirl your Chemex gently, and serve. As your coffee gradually cools, enjoy the evolving flavors.
