Coffee connoisseur the world over will tell you that grinding your coffee beans right before brewing is the best way to have your cup. Pre-ground coffee beans are alright at first use because the packaging is vacuum sealed. Once the seal is broken, the ground coffee loses its aroma and flavor. The longer that your coffee is exposed to air, the more it loses its aroma. In light of the growing demand for the just the right kind of brew, coffee drinkers are now switching to the practice of grinding their own coffee beans. Note that even coffee beans lose their flavors and aroma once in contact with air. So be sure to keep the beans in a dark airtight container or you can freeze them.
Grinding coffee beans is an art. You just don’t throw in a handful of coffee beans in a grinder, hit automatic grind and hope that your grinds will come out fine. For the real coffee lovers, choosing the best grinder to go with their coffee makers takes a lot of time. They search the internet, ask friends, and window shop for grinders even. What are the choices for the most suitable coffee grinder for you?
There are technically two kinds of coffee grinders that are popular to coffee lovers. There is the blade coffee grinder and the burr coffee grinder. Under the burr kind, there is the regular wheel grinder and the conical burr grinder.
Conical Burr Grinders may be the best type of coffee grinder today. It preserves aroma at its highest and easily grinds to beans to a very fine consistent. The steel burr is cone-shaped where the large cone holds the beans while the smaller cone grinds the beans at a slow and sure pace. The lower the speed the less heat will be produced. The intricate design of the steel burrs allows a high gear reduction to slow down the grinding speed. The slower the speed the less heat is imparted to the ground coffee thus preserving maximum amount of aroma. The grinding speed is below 500 rpm (revolutions per minute) this burr grinder is perfect for espresso and Turkish coffee. As the burr grind can “grind” coffee beans at the desired fineness, it is also a great complement to drip, French press and percolators.
Burr grinders with disk or wheel type burrs grind at a faster speed of 10,000 to 20,000 rpm. At this speed more heat is produced but is not a cause for worry as it will not leave a bunt after taste on the beans. The conical burr grinders and create a bit more warmth in the coffee (10,000 to 20,000 rpm). This is type is less expensive than the conical burr but it is good enough to produce consistent grinds. This type could be a great partner for any coffee maker but it is best suited for espresso coffee maker. However fine the ground, the degree of fineness is cannot match the ones from a conical burr.
The blade coffee grinder does not actually grind the beans but it rather chops and hacks and rotates the coffee beans with a speed of up 30,000 rpm. The result is bigger and uneven coffee granules that might have a hint of burnt taste. Because of the inconsistency of the grind, coffee dust is created in the grinder and this dust can clog up dandy espresso and French press. The uneven-sized grounds are perfect for drip coffee makers and percolators. This gadget can also grind nuts and spices.
If there are wine connoisseurs who can tell the vintage and from what vineyard the wine came from just by tasting the wine, a coffee connoisseur can tell you if the coffee beans are blade or burr grounded. This is why coffee lovers grind their own coffee.
