Why Pour-Over Coffee Stalls or Drains Too Fast

Pour-over drain time reflects grind distribution, filter properties, coffee bed depth and pouring. Change one cause at a time instead of assuming the grinder is always responsible.

Good starting point

Start from a normal dose such as 20 g coffee and 320 g water, and note time after each controlled pour.

What to know before you begin

Do not force a fixed time benchmark across different drippers, filters and dose sizes.

Step-by-step method

1. Check whether the paper filter is properly seated and fully opened.
2. Confirm the coffee dose is suitable for the dripper size.
3. If draining very slowly, test a slightly coarser grind without changing the pour.
4. If draining rapidly and the flavor is thin, test slightly finer while keeping water constant.
5. Repeat with the same filter type and count pulses so comparisons remain fair.

Problems to recognize

• Over-aggressive stirring can move fines and block paper pores.
• Pouring directly down the filter wall can increase bypass and shorten contact.
• Changes in roast or grinder retention can shift flow without you touching the dial.

Run a useful comparison

Log total drawdown for three cups and pair each number with taste; the “correct” number is only useful if flavor improves.
