“I grind my own beans, thank you” that's a sentence that you must have heard before (unless you're the one usually saying it).
There has always been a debate among coffee connoisseurs to choose between whole bean or ground coffee. The is really no wrong choice, it just depends which one you consider most beneficial.
Most people buy and use ground coffee, mainly because that is the easiest to use and the form that is found on the shelves of every local supermarket. It's ready to brew, and won't require any extra time, skills or equipment on your part. And that pretty much sums up all the positive aspects of pre-ground coffee. Ease and convenience.
Those who go for whole bean is because of freshness. Once the coffee has been roasted and ground, coffee will go stale fast. All the taste is in the bean oils, and they will evaporate once the beans are ground up. Even cans of coffee that have been vacuum-packed are going to be a lot less fresh than the coffee you grind yourself also depending on the grade of coffee you buy. The also lies the problem too, some people don’t want the extra effort involved in doing the grinding themselves.
The bottom line is that between whole bean and ground coffee, the things to consider are freshness, control, and convenience. Whole beans will give you a fresher cup and you can decide your own level of coarseness, but ground coffee is ready without any work.
