  1. Ground coffee that’s been ground with a great burr grinder is better than whole-bean coffee that’s been ground with an inferior blade grinder. The key is evenness in particle size and the former produces particle sizes of a much better uniformity. Whole-bean that’s just been ground will release volatile aromatics which you ideally want to capture in the brew making process so whole-bean that has just been ground with a burr grinder is best.

  2. By putting aside all those instant soluble brands, overly dark roasted crap, coffee with lots of additives such as sugar and milk, I assume you’re talking about coffee ground that comes from roasted coffee beans.
    The downside of grounded coffee is that it won’t last long on your shelf, some also says that the amount of caffeine will also decrease along with time.
    The shelf life of green beans can go up to months, some people even say it will last for years, but generally a roaster will say it will last up to 3 months or so (as far as I know).
    The shelf life of roasted beans are even shorter, up to 30 – 45 days, depends on the beans quality.
    Coffee ground deteriorate faster, even more if you don’t store them properly, but generally it will only last for 2 weeks in a proper storage after grinding. You will lose the whole bunch of stuffs by pre-ground your beans: taste, aroma, probably even the caffeine content.
    I trust no other brand than “illy” for pre-ground coffee, given their good packaging. You need to pay extra caution in buying pre-ground coffee since it’s a widely known secret that most manufacturers will have tricks to reduce the production cost, for example:
    Mixing the coffee with grinded roasted corn or rice.
    Over dark roast, to mask the defects and bad taste.
    Infusing with other chemicals to differentiate product.
    So, my advice is, if you have to buy a pre-ground, make sure it comes from roasted beans.

  3. Well, it’s pretty hard to make coffee from coffee beans if they’re not ground first! Perhaps you mean pre-ground coffee, where it’s ground before you buy it.
    Once ground, coffee loses freshness and flavor. But for perfectly good convenience reasons most folks buy coffee pre-ground. Or have the beans ground in the shop when buying it. And it tastes good for a week or two.
    If you have your own coffee grinder there’s a benefit to buying whole bean, and grinding a serving of coffee each time you make it.

  4. In general: no . It is not bad.
    If we deep into the coffee quality, we’ll find out very fast that the quality of the coffee drink (which is the most important quality factor of coffee consumption) is based on many aspects of the whole coffee “path” from scrub to cup. In general, if the material (roasted beans) are the same, the following rules are true:
    fresh grind is always better than pre-grind coffee,
    quality water is always better than tap water,
    consistent dosing is always better than ad-hoc quantity of ground coffee,
    consistent brew quantity is always better than ad-hoc quantity of brewed coffee,
    consistent temperature is always better than inconsistent.
    The whole coffee preparation method is about consistency (the same protocol, quantity, setting through every single portion of coffee). Some factors are mandatory, other factors are less important, and each of them can ruin your cup on its own. Or, as an opposite, a single change in one factor only may make your coffee better. So, my suggestions are:
    use a scale to measure the ground and the drink in the cup,
    use descaled, quality water instead of tap water (I prefer BWT),
    try to be as consistent during the coffee preparation method as you can (whatever you make an espresso, a french press or a kalita),
    and at last, but the most important over the above: use fresh grind . I mean, right before you prepare the coffee.
    As a not too strict thumb of rule, the following rules are applicable to classic dark roasted, whort Italian espresso:
    green beans are good enough for three years (if stored under good conditions),
    roasted beans are best for three months,
    ground coffee is good enough for three hours,
    a cup of espresso is good enough for three minutes.
    Of course, shorter is better.
    Thanks for a2a.
