One of the best way to improve the coffee and espresso that you make at home is to have some of the right coffee making accessories. Things like a water filter to improve the water, good storage containers for keeping your coffee beans fresh longer are simple additions that can make a good coffee even better.
Another upgrade that can make a huge difference is your coffee bean grinder. Most inexpensive grinders are blade type grinders. These grinders spin very fast and this can actually cause the coffee grinds to become burnt during the grinding process if you aren’t careful. A burr coffee grinder does a MUCH better job of grinding your coffee beans. With a burr grinder you also have better control of the size of the grinds so you can adjust for different styles of brewing.
