Adjusts the leaf amount and steep time. Strong adds 25% more leaf and 25% more time; light reduces both.
Second and subsequent infusions of the same leaves need longer time to compensate for reduced extraction.

Brew at 98 °C for 3 min - 5 min.

  • Use water at 98 °C - this sits in the sweet spot for black to extract flavor without releasing excess bitterness.
  • You need about 2.5 g (roughly 2.9 tsp) of loose leaf for this brew volume.
  • These leaves can be re-steeped up to 1 more time - add about 30% more time for each subsequent infusion.

Next stepTaste at the lower end of the steep time first, then adjust in future brews to dial in your preference.
