Best Grind Size for Vietnamese Phin Coffee
Your grind size controls the drip speed, strength and taste. This guide helps you find the sweet spot between watery and blocked.
For Phin coffee, aim for a grind between pour-over and espresso: finer than French press, but not as fine as espresso. The right grind should give you a slow, steady drip in around 4-6 minutes.
The Grind Scale
Fast and Watery
The coffee drips too quickly, often in 1-3 minutes. The cup tastes thin, weak and diluted over ice.
Slow and Balanced
The first drops appear after the bloom, then the full brew finishes around 4-6 minutes with good strength.
Blocked and Bitter
The Phin barely drips or takes too long. The cup can become harsh, bitter or muddy.
The simple rule
If your Phin finishes too fast, grind a little finer. If it barely drips, grind a little coarser or press more lightly.
Best Match by Coffee
