WORKFLOW
Adjust your Brew boiler Temperature:
Dial To 98°C ( 208.4°F): Higher than normal basket Situation.
Suggest Water Debit:
80~200ml/10sec, small water debit will cause some unstable extraction.
Grind beans:
RDT if you want.
14~18grams for H24.7 , I would suggest 16g would be a good start.
Grind finer(3 intervals or notches ) than normal, somewhere close to Turkish garde. e.g. If you use 18gram before, try 16 gram dosage but Finer ground.
Prepare your puck:
No Bottom Filter Paper.
Wdt if you want, I think that helps, especially when extract under low bar.
Easy Tamping within 15 kgf , Flat base or Ripple base.
After Tamping ,No Top Paper ,No Metal Puck Screen.
Preinfusion with Low Pressure and shorter time:
e.g. 0.5~2 bars, no more than 5 sec.
Brewing Pressure:
The lower the pressure the higher the flow rate.
Light Roast : 4~5 bar
Medium to Dark Roast : 5~9 bar
No more than 9 bar
Brewing Time:
Doesn't really matter how long it takes, stop when you think its enough coffee liquid to drink.
Brew Ratio:
From 1:3~1:20 will be recommended.(YES, 1:20 not a type error)
High quality light roast beans can reach the high ratio.
After brewing ,rinse basket with hot water, and detach portafilter from your group head.This helps to prevent basket from clog coffee grounds.
