Brewing Tips and Tricks

An ordinary mug typically holds about 240 to 350 milliliters (ml) of liquid.


  • Grind Size: The grind size significantly affects the extraction process and the final taste of your coffee.
    • Coarse grind is ideal for French press and cold brew.
    • Medium grind works well for drip coffee makers.
    • Fine grind is best for espresso.
  • Water Temperature: For coffee, the ideal brewing temperature is between 195°F and 205°F (90°C to 96°C). Let boiling water sit for about 30 seconds before brewing to achieve this range without a thermometer.


  • Steeping Time: Different types of tea require different steeping times.
    • Green teas: 2-3 minutes
    • Black teas: 3-5 minutes
    • Herbal teas: 5+ minutes
  • Water Temperature: Different teas require different temperatures.
    • Green and white teas: 160-185°F (70-85°C)
    • Black and oolong teas: 190-200°F (88-93°C)
    • Herbal teas: Boiling water (212°F or 100°C)

Why Temperatures and Times Matter:

The extraction process is crucial in both tea and coffee making. The right temperature and time ensure that the flavors are extracted perfectly, without extracting too many bitter compounds. This balance is what creates a delightful cup.

Fun Facts:

  • Coffee: Coffee was originally chewed, not brewed. In Ethiopia, where coffee originates, natives would mix coffee berries with fat to create energy-rich snacks.
  • Tea: Legend has it that tea was discovered by Chinese Emperor Shen Nong in 2737 BC, when leaves from a wild tree blew into his pot of boiling water.
