Enjoy coffee, enjoy life.
There are two types of coffee... neck up coffee, and neck down coffee.
We just timed our process for brewing 2 16oz travel mugs of coffee in the morning. Measured beans, ground them, put water in our drip brewer, added the filter, brewed and then filled the mugs. It took 5 minutes and 33 seconds (approximately 4 of those minutes we spent feeding the kids breakfast while our Moccamaster did all the work.) To us the extra minute of preparation is a better way to start each day. Take an extra minute and start your day with a "neck up" morning like we do.
Why grind before brewing? Science is why. When green coffee beans are roasted, CO2 gasses are temporarily "trapped" within the beans during the roasting process. By grinding the bean just before brewing, you release the CO2 aromas enhancing the taste of your brew. (This is why coffee bags have those little one way valves on them.) Also, the CO2 gradually escapes from the bean over time, and is why coffee that has been sitting on a store shelf for several months does not taste as good as fresh, locally roasted coffee.
