http://coffee-addict.com Electric coffee grinders are excellent tools for grinding your favorite coffee beans at home for maximum freshness and flavour. But there are various kinds of grinders you should know about before you buy. The first kind is metal blade coffee grinders. They make use of spinning metal blades that quickly chop the coffee beans into powder. These are the cheapest kind, but they produce uneven coffee grinds that lead to somewhat inconsistent coffee flavour, at least to the serious coffee lover. The second kind of grinder is burr grinders, which make use of a grinding wheel that rubs the coffee beans against a flat surface. These result in more consistent coffee grinds. The best kind of burr grinder is a conical burr grinder, which doesn’t clog easily so it can be used for gourmet and flavoured coffees without hassle.
