Chemex
Equipment Needed:
- Chemex
- Filtered Water
- Kettle
- Scales
- Timer
- Stirrer
-
Coffee (5-10 Days after Roast date is best)
- 1. Boil Water (90-94°C) . For this recipe we'll be using 94ºC or 90 seconds off the boil from your kitchen kettle.
- Experiment with different water temperatures once you feel comfortable with brewing this method
- Make sure to use filtered water either with a BWT bestmax filter jug or bottled water from the supermarket, we find ashbeck from Tesco works quite well.
- 2.Weigh 30 grams of coffee, and grind to the consistency of demerara sugar
- 3. Fold chemex paper into a cone or if you have the pre-folded papers just pop one in the brewer.
- 4.Once the Kettle is boiled rinse the paper with a good amount of water, this gets rid of the papery taste & will improve the final flavour of the brew.
- Discard the rinse water.
- 5.Add the ground coffee to the brewer. Shake gently to level the surface.
- 6. Start your timer & begin to pour slowly keeping the stream of water from the pouring kettle in a vertical line.
- Pour 90g of water onto the coffee leave to bloom for 30 seconds, gently spin the bloom a few times. This will increase extraction by making sure all the grounds get saturated.
- 7. After 30 seconds continue to pour in circular motions from the centre out to edge edge & back into the centre pour to a target weight of 300g let this drain through for 30 seconds
- Try not to pour water down the sides of the chemex as this will lead water passing through to quickly, causing uneven extraction.
- Continue to pour until the final target weight of 500g, gently spin a couple of times to stop coffee sticking, this will increase extraction and should stop the chemex choking.
- If the chemex begins to choke, gently lift the paper up and set it back down into the brewer
- Aim to have all the water in the chemex by 2:30 and allow to drip through. Your total brew time should be around 3/3:30. If your brew goes over 4 minutes still try it and if its ok write down your grind size setting to replicate the brew.
- If your brew tastes bitter, adjust your grind size coarser and rebrew
- If your brew tastes thin and watery, adjust your grind size finer and rebrew
- These brew times are a ball park figure, every coffee is different and some will taste better brewed longer/ shorter. Experiment with your grind size and see where you get the best results.
