Every time I make coffee it seems to taste different, and I've found there is a lot more room for error with the manual drip-brew method than using a Moka coffee maker or an automatic drip-brewer.
There are too many variables to list, but I'll try:
- Type/color/brand of filter
- Amount of coffee
- Wetting the filter
- Wetting the grounds
- Amount of time between wetting the grounds and pouring the rest of the water
- Plastic / ceramic / glass cone
- Coarseness of the grounds
- Rate of water flow
- Temperature of water
- Height from which to pour water
- Trickling water or constant pour
- Clockwise / counterclockwise / or straight-on pouring
- Whether to fill it up to the brim and let it seep down or be patient and pour a little at a time
- And many more.
But what are the most important factors (either from this list or anything I might have missed) that I need to do every time to ensure that the cup is a most excellent brew? How do those factors actually affect the brew and why?
Please include only factors specific to, or of particular import to this method of coffee brewing.
