Common Questions
What grind size for pour over?
Medium-fine, similar to table salt. V60 tends to work best slightly finer, while Chemex benefits from a slightly coarser grind since its thick filter slows the drawdown. If your brew runs too fast (under 2:30), grind finer. If it stalls past 3:30, go coarser.
Does the ratio change for Chemex vs V60?
The starting ratio is the same (1:15), but you might adjust based on taste. Chemex's thick paper filter absorbs more oils, so some people drop to 1:14 for more body. V60 lets more through, so 1:15 to 1:16 often works well. Experiment and trust your palate.
How do I make pour over less bitter?
Bitterness usually means over-extraction. Try a coarser grind, slightly cooler water (90-94 C instead of boiling), or a faster pour. You can also try a higher ratio like 1:16 to reduce intensity without losing flavor.
