NOT FRESH

8bar/92C

• 6/20.0g -> 7/36s 40.1g 0.6~1.5ml/s, sweet, a little bitter in aftertaste
  • first cup of the day, try again
  • too fast, next day try waiting for 10 minutes before first cup
• 6/20.0g -> 37.4g 7/42s, obvious bitter
  • “rinse and hold” state reaches maximum
• 8/20.0g -> 7/24s 42.2g 1.7~2.1ml/s, less sweetness, flavor fine but could be more emphasized

6bar/92C

• 8/20.0g -> 7/25s 39.4g 1.5~2.2ml/s, flavor enough

6bar/94C

• 8/20.0g -> 7/28s 40.3g 1.2~2.1ml/s, more sweetness, less flavor, thickness might be not enough, a little bitter in aftertaste
  • try 8.5/9 grind, and raise pressure
• 8.5/20.0g -> 7/22s 40.9g 2.0~2.3ml/s 94~93~94C, bitter, ~taste like channeling~
  • frist cup of the day
  • difference of the taste could due to food prior latte
• 8.5/20.0g -> 7/21s 40.6g 2.2~2.5ml/s 93.7~93~93.5C, more balanced, sweet
  • waiting for 12 minutes before the first cup looks pretty stable in extraction

9bar/94C

• 8.5/20.0g -> 7/20s 40.7g 2.2~2.4ml/s 93.7~93~93.5C, thicker body, just a little bit less emphasized flavor in the beginning but increased later, not bitterness at all
• 8/20.0g -> 7/26s 40.4g 1.3~1.9ml/s 93.5~93~93.7C, a little bit more sweet, thicker body, a little bit but comfortable bitterness in aftertaste, turning weak sweet later
