6bar/94C

• 2/15.0g -> 7/15s 30.1g 2.7~3.1ml/s, clarity not enough, very sweet, no obvious aftertaste
• 1/15.0g -> 6/20s 30.3g 1.4~2.2ml/s, less sweetness, is it a little over extraction?

2.0ml/s -> 2.0ml/s on 8bar/94C

• 1.5/15.0g -> 15/26s 29.9g 5.8~3.1bar, balanced
  • yes!
• 1/15.0g -> 16/28s 30.0g 5.7~3.1bar, a little less sweet and more bitter
  • 1.5 grind still better
• 1.5/15.0g -> 14/26s 30.0g 5.4~3.6bar, a little bit bitter
  • used organic valley instead of maple hill
• 1.5/15.0g -> 13/25s 30.1g 5.0~3.1bar
  • used maple hill again, taste of fat in milk is obvious

4.0ml/s -> 3.0ml/s on 9bar/94C

• 1.5/15.0g -> 7/19s 30.2g 9.2bar 1.5~2.2ml/s, more balanced
  • failed to reach 3ml/s, ground too fine to reach the flow under pressure limit

4.0ml/s -> 1.0ml/s on 9bar/94C

• 1.5/15.0g -> 7/32s 29.8g 6.6~2.3bar, less creama, brighter but less thickness
  • low flow -> low pressure -> slightly less extraction
  • needs further verify

4.0ml/s -> 2.0ml/s on 9bar/94C

• 1.5/15.0g -> 7/22s 29.8g 9.3~8.6bar, a little under extraction

9bar/92C

• (2024-12-18)
• 2/18.0g -> 7/24s 36.0g 1.4~2.0ml/s, taste like over extraction
• 2.5/18.0g -> 7/22s 36.0g 1.7~2.1ml/s, balanced, sweet
  • yes!
• 3/18.0g -> 7/20s 35.9g 2.0~2.3ml/s, a little bit sour but tastes fruity
  • try again, also a little bit uneven

9~1bar/92C

• (2024-12-25)
• 3/18.0g -> 7/19s 36.0g 2.3~2.8ml/s
  • degases but flavor emphasized while a little feeling of under extraction
  • try 2.5 grind next time
• (2025-1-3)
• 2.5/18.0g -> 7/22s 36.0g 1.7~2.0ml/s, black tea too heavy
• 3/18.0g -> 7/19s 36.0g 2.1~2.6, better
• 3.5/18.0g -> 8/17s 36.1g 2.8~3.0ml/s, sweet, flavor emphasized, but a little bit under extraction
  • try 3.25 yield
• 3.25/18.0g -> 8/19s 2.4~2.8ml/s
• 3.25/18.0g -> 8/20s 35.9g 2.0~2.6ml/s
