Ground coffee deteriorates rapidly. A lot of flavors and aromas are loss during storage and transport. That is why many coffee lovers choose to buy whole roasted coffee beans and grind it just before brewing.
Brewing methods must be considered before commencing. The size of ground coffee particles affects the brewing results. Long method requires coarse grind while short brewing needs fine particles.
Long brewing matched with finely ground coffee will result in overly extracted bitter coffee. On the other hand, short brewing matched with coarse grind will result in blunt and poorly extracted cup. The examples of long brewing are boiling, percolator, drip-brewing and steeping with coffee bags. While express methods uses espresso, moka pot and senseo.
If you love drinking coffee, you may want to grind beans on your own as well. Grinding your own coffee is such an easy task. The following explanation may help you decide the grinding style to use for an enjoyable cup experience.
1. Burr grinding. The principle involves the use of two revolving plates crushing beans in between. Plates gap can be adjusted to attain desired particle size.
Manual burr grinders are less expensive and will give you more control over the size and uniformity but it is only feasible for home grinding. Electronic high speed burr grinder do the job fast but tends to overdo it. Electronic low speed burrs are ideal for obtaining wanted granule size and consistency.
2. Chopping. It is carried by blade assembly rotating at high speed. Tend to produce a fine powdered coffee.
3. Pounding. Can be done through the use of mortar and pestle. Grind size and uniformity is hard to control. It is also slow and messy. Do this only if you have no budget to buy a regular mill.
4. Roller grinding. Similar to burr mill except that this one uses rollers instead of plates.
