The Bunn coffee grinder is a portion control grinder. You can grind only the amount of beans you need for one or two cups of coffee or as many as 12 cups, depending on the size of your coffee percolator. Of course, if you have a commercial coffee maker, you will need a large model so that you can grind large amounts of coffee beans at a time. You can choose the settings you want on this grinder as well. For regular drip coffee makers, you will need coarse grinds, but if you have an espresso machine, you will need to grind the beans really fine.
Bunn makes the grinders and coffee pots that you need for your home or commercial use. If you want to have fresh coffee every time, you can grind the beans and then make the coffee right away. You not only get the taste and aroma of the coffee when you brew it, but you also have the aroma of the beans before you put them into the grinder.
Expert coffee drinkers will tell you that the only way to have a fresh cup of coffee is to grind the beans immediately before you brew a pot. Although you can grind up the beans and store them in a container, they do lose their freshness after a few days because of oxygen and moisture.
With a Bunn burr grinder, you don't have to change any burrs to get the right texture of grounds that you want. Simply switch the setting on the grinder to have the perfect consistency every time. Instead of chopping the beans, the burr grinder shaves them in a slow rotation so as to reduce the friction. This preserves the taste of the coffee beans because the grinder doesn't allow them to heat up as much as the blade models.
That being said, Bunn does also have blade models in the grinders as well as manual coffee mills, so you can actually grind by hand. It doesn't add any extra time to the coffee making process, whether you use the manual or electric grinders. You can still prepare the coffee in the night to awaken to the aroma of freshly brewed coffee in the morning. Now you don't have to make time to stop at Starbucks on the way to work because you can have your gourmet coffee at home.
