Brew ratio: 60 g/L (e.g. 30 g per 500 mL)
Grind size: medium fine
Temperature: the hotter, the better (especially with lighter roasts)
Grind 30 g of coffee
Rinse paper filter with water just off the boil
This removes any paper taste and preheats the brewer
Add coffee grounds to V60
Create a well in the middle of the grounds
This helps to evenly saturate all the grounds during the blooming phase
Don’t use more than 3x coffee weight
The aim is to wet all the coffee grounds by evenly mixing bloom water and coffee
Swirling is better than using a spoon
This allows CO2 to escape which will improve extraction
This phase is critical! Since you already added 60 g bloom water, add 240 g in 30 s (flow rate = 8 g/s)
A full V60 is good to maintain high temperatures
P.S.: Don’t worry about pouring directly onto the V60 filter
Since you already added 300 g water, add 200 g in 30 s (flow rate = 6.66 g/s) Poor a little slower than in the first phase, not too aggressively
This knocks off grounds from side wall
Allow V60 to drain a little
Give V60 a gentle swirl
This helps obtain a flat coffee bed at bottom of V60 for even extraction
The higher the temperature, the faster the drawdown
Filter paper also affects drawdown
Aim to finish drawdawn by t = 3:30
40-44 on Omnicup (20-22 on Comandante). I prefer 41 in most cases.
40 - too bitter, flavores are left suppressed.
41 - best balance between the usual slight bitterness of coffee and basic aroma. Rich aftertaste.
42 - the bitterness is easy to miss, hard to dissolve individual notes.
44 - the bitterness is gone and so is the rich flavor
All experiments done with 15g of coffee to 250g of water.
