clean, make sure to always clean coffee basket and such. oils go rancid. coffee is full of oils.
fresh, fresher the roast the better. coffee degrades very quickly. grind at brew time to help garrnatee freshness. if using a larger coffee maker for single serving make sure it has a single serving mode, some may not get hot enough quick enough. err, make sure to use enough grounds. overextraction leads to yuck.
stay away from french press. gets cold too quick, its basically almost luke warm by the time its done plus, the chemicals paper filters catch are the ones that harden ur arteries.
