The Seven Pillars of Coffee Brewing Wisdom

1. Boiling causes bitterness, so never boil coffee.
It should be brewed between 90°C - 96°C.
2. Do not reheat coffee.
Make it fresh each time you serve it, and make only as much as you
plan to drink. Coffee holds its flavor best 86°C.
3. Use freshly drawn, cold water.
Water is 98 % of every cup; consider using a water filter or bottled
water if your water tastes peculiar.
4. Do not reuse grounds.
What remains are the unpleasant bitter component of the coffee.
5. Use the correct grind for your coffeemaker.
Too fine a grind will cause overextraction and bitterness, or clog your
brewer. Too coarse a grind will cause watery coffee.
For drip brewers, the appropriate grind should allow the coffee to
finish dripping in several minutes.
6. For the best results, we recommand using 10 g of ground coffee for
each 180 mL of water.
Keep these proportions consistent, regardless of the quantity you
make. To moderate your's coffee strength, simply add hot water after
brewing.
7. Coffee can be kept warm over a burner for only about 20 minutes
before the flavor becomes unpleasant.
An air pot or vacuum server will keep coffee hot and delicious for
much longer periods of time.
