The flavour in a coffee comes from the oils that are present in roasted beans. If you want to extract flavour from the beans as effectively as possible you should choose to invest in a good quality coffee grinder. A grinder not only helps in grinding coffee beans but it is also effective in altering the consistency of grinds, depending on the brewing method.
The blades inside a blade coffee grinder are quite effective in producing coffee grinds that are less uniform in size than a burr coffee grinder. The flavour of coffee ground by a blade grinder is not up to the mark as in the case of a burr coffee grinder or a bladeless coffee grinder. Burr coffee grinders or bladeless coffee grinders comprise of two oscillating serrated plates which work in tandem to crush and literally grind the beans. They do not cut the beans unlike a blade coffee grinder. Hence there exists no question of uniformity in them. By adjusting the distance in between the burrs, you get to have control over the consistency of the coffee grinds.
Blade grinders produce coffee grinds which are less uniform in size when compared to a burr grinder. The blade grinder though is the best choice for people who are on a tight budget. Automatic coffee grinders and manual coffee grinders are the other varieties when it comes to coffee grinders. Automatic grinders are undoubtedly the best choice. In case of automatic coffee grinders, you just have to pour the beans, hit the button and wait to get your preferred choice of coffee. It does not create any fuss.
