Espresso – Brewing the Perfect Shot at Home
For the avid coffee lover, there is nothing like a quality burr coffee grinder. The freshest and best flavored coffee comes from freshly ground coffee beans. The aroma and freshness comes from the oil inside the bean. When freshly ground, the oils are very flavorful and aromatic.
A bladed coffee grinder cuts the bean in uneven pieces that get smaller the longer you run the grinder. A burr coffee grinder crushes the bean between a moving ใบเจียร part and a non-moving part to get a consistent size of grounds.
The problem with a bladed coffee grinder is that the friction caused by cutting at high speeds, heats up the oils and sometimes, even burns it while grinding, giving the coffee a bitter or burnt taste. The inconsistent size of the grounds also affects the brewing process, where some of the flavor is not fully released and the essential oils are missing from the finer grounds.
The benefits of a quality burr coffee grinder is that not only does it not over-process by heating or burning the essential oils, but the grounds are consistently even, whether you prefer a course or fine grind. Because a burr coffee grinder runs at a slower speed, it does not overheat the coffee beans like a bladed coffee grinder does.
Burr coffee grinders can be adjusted for course or fine grounds, depending on the positioning of the burr or the metal discs that do the grinding. There are two types of burr coffee grinders-a wheel burr or a conical burr.
A Wheel Burr coffee grinder is the least expensive but they can be quite noisy and messy. The wheel spins very fast to grind the coffee, and they are more prone to clog than a conical burr coffee grinder.
The best type of coffee grinder is a Conical burr, although they will be more expensive than other grinders. The burr spins slower than the wheel type of grinder and they are quieter and don’t make as much of a mess. They are great for flavored coffees or oilier types of coffee beans and they clog less than any other model of coffee grinder.
The benefits of a quality burr coffee grinder is that they are built sturdy, and will last through the years. Burr coffee grinders carry different price tags, but the pricier models are leap and bounds above their competitors.
The conical burr coffee grinders allow you to control the fineness of the grind, which greatly enhances the ability to grind to the flavor that suits your taste. For coffee connoisseurs, the heftier price tag is well worth the enhanced flavor and a quality burr coffee grinder is a once in a lifetime investment.
