9~9bar/92C

• 10/20.0g -> 8/23s 30.8g, bitter
• 10/21.0g -> 7/21s 30.5g, less bitter, more sweet

9~7bar/94C

• 10/21.0g -> 8/20s 30.6g, strong and clear flavor, sweet
  • yes!
  • try 9 grind next time

9~9bar/94C

• 10/21.0g -> 8/24s 40.0g, much more body
  • still prefer 1:1.5 yield

9~7bar/94C

• 10/20.0g -> 10/20s 31.7g, bitter and slightly sweet aftertaste
• 10/22.0g -> 7/22s 31.2g, dose too big
  • 22g does not fit in 20g basket

9~9bar/94C

• 10/21.0g -> 7/19s 30.2g, balanced, sweet
  • yes!
  • grind » pressure = temperature
• 9/20.0g -> 7/21s 29.9g, bitter
• 10/20.0g -> 7/17s 32.5g, milk tea, flavor enough, not clarity enough, not bitter at all, somewhat sweet aftertaste, sweetness comes later
  • better, need to improve characteristic without brining more body
  • 1g less dose decreases body a lot, it might because of the higher flow rate, jumps from 2.5 to 3.5

FRESH

9bar/94C

• 10/20.0g -> 7/19s 41.4g 2.5~3.5ml/s, obvious taste of fementation, clarity, milk tea, sweet in aftertaste, a little bit bitter long lasting
  • first cup of the day, data doesn’t match record, try again
• 10/20.0g -> 7/19s 40.7g 2.5~2.8ml/s, sour, not bitterness, less sweet, less milk tea
  • machine stable, previous cup proven channeling
• 8/20.0g -> 6/42s 40.4g 0.4~1.5ml/s, over extraction
• 9/20.0g -> 7/29s 39.8g 1.0~2.0ml/s, much less but still bitter
  • try 9.5 grind
  • try 10 grind with 7/9~4bar
• 9.5/20.0g -> 6/22s 40.5g 1.8~2.2ml/s, flavor over emphasized, obvious sweet aftertaste
  • first cup of the day

9~4bar/94C

• 9.5/20.0g -> 7/24s 40.3g 1.6~2.2ml/s 9~7.8bar, less emphasized citrus flavor, milk tea, less sweet in aftertaste
  • a little bit taste of glass when getting cold
  • flavor should have been emphasized by dropping the pressure, but here it may because of the dropping of density
  • sometimes dropping pressure doesn’t dramatically affect flownrate this much, this could also be the reason

9~4bar/92C

• 9.5/20.0g -> 7/26s 40.5g 1.5~2.1ml/s 9~7.3bar, increased body (why?) and milk tea feeling, sweet aftertaste comes later but long lasting
  • decreasing temperature seems to affect to pressure as well
  • the best temperature on sweet aftertaste seems to drop when pressure drops
  • flavor emphasized when getting cold
• 9.5/20.0g -> 8/25s 40.2g 1.6~2.1ml/s, much more sour
  • first cup of the day
  • use a wide cup, it seems to lower the temperature od the espresso too fast
  • flow rate and time looks right, changing of the taste could due to the temperature drop
• 9.5/20.0g -> 7/23s 40.8g 1.7~2.2ml/s, sweet, good thickness, obvious critus flavor than yesterday and lasts in aftertaste
  • back to the deep cup for consistency
  • flow rate increases a little bit
• 9/20.0g -> 8/31s 39.9g 0.9~1.9ml/s, more sweet, significantly less flavor
  • will increasing density bring the emphasized flavor (no) or sweetness back (yes)?
• 10/20.0g -> 8/21s 40.2g 2.2~2.7ml/s, less sweet, significantly more flavor and even too much
  • will increasing flow rate bring the emphasized flavor (yes) or sweetness back (no)?
  • looks like 9.5 in 9~4bar/92C is still too sour but also the most appropriate grind setting

9~9bar/94C

• 9.5/20.0g -> 7/25s 39.6g 1.3~2.1ml/s, slightly bitter
  • first cup of the day, flow rate a little but slower at the beginning
  • 1/2 step is obviously too large for this bean, it is necessary to try 1/4 step
• 9.75/19.9g -> 7/20s 39.6g 1.9~2.3ml/s, flavor emphasized, little smoky, citrus long lasting
  • flow rate looks right

9~9bar/92C

• 9.75/20.0g -> 8/21s 40.3g 2.4~3.1ml/s, bitter, could be channeling
  • flow drops and raises too late
• 9.75/20.0g -> 8/23s 40.2g 1.8~2.3ml/s, flavor a little bit over emphasized, very little sweet in aftertaste comes late

9~4bar/94C

• 9.75/20.0g -> 8/22s 40.1g 1.8~2.3ml/s, flavor emphasized, little smoky, citrus, a little sweet in aftertaste

9~4bar/92C

• 9.75/20.0g -> 9/24s 40.3g 1.7~2.3ml/s, balanced, smoky, milk tea, citrus, sweet
  • yes!
  • try 15.0g and finer ground to achieve a similar flow rate
• 7.5/15.0g -> 6/22s 36.2g 1.6~2.0ml/s, a little bitter
  • scale does not put in a right position and failed to stopsnat 30g
• 7.5/15.0g -> 6/21s 30.5g 1.4~1.8ml/s, flavor a little bit over emphasized, thickness is good, a little sweet aftertaste comes later
• 7/15.1g -> 6/22s 30.2g 1.2~1.8ml/s, very similar to 9.75/20.0g
  • try 9~1bar and see how low the pressure goes
  • it looks like lower dose needs lower flow rate to keep the same taste
  • part of the reason might be lower yield of espresso gets colder easier, which will eventually over emphasize the acidity

9~4bar/92C, Scale calibrated

• re-evaluate the last recipe and apply to CGLE logs

• 7/15.0g -> 6/14s 2.8~3.4ml/s
• 6/15.0g -> 6/19s 1.8~2.0ml/s, citrus emphasized in a good way, milk tea, some sweet in aftertaste
• 5.5/15.0g -> 6/23s 1.1~1.8ml/s, sweet, a little smoky, citrus emphasized but comes later, some sweet in aftertaste
  • this looks like 7/15.0g yesterday
  • needs to compare using CGLE
• 6/15.0g -> 7/21s 30.1g, 1.4~1.9ml/s, sweet, smoky, balanced
  • this also looks like 7/15.0 yesterday, since Niche Duo zeroing only adjust by 1, this should be correct

9~1bar/92C

• 8.25/20.0g -> 8/19s 40.1g 2.6~3.5ml/s, looks like channeling
  • last dose of this patch
