There are many factors involved with regards to determining what exactly is a good coffee to purchase and roast. A cut-and-dry approach that works well for many beans will not exist.

Before electricity and gas, people used plain old fire to create coffee! They used wood fire and big pots, plus they ground their coffee with stones or wood.

Many of the machines that you will find in the stores look highly efficient. Some of them have a grinder, espresso maker, and drip-maker all rolled into one convenient device which will save money and counter space.

Coffee purists will argue that the drip maker doesn't offer enough control of the finished product. However, the convenience of use and cleanup make auto-drip a rather popular brewing method.
