Why do some small businesses not grow? I believe the main reason is that these small businesses wants their growth the same as their coffee. When their budget is tight they are indeed prepared to make the coffee themselves, so they make instant coffee. When funds become available they buy freshly roasted coffee from a drive through, instantly.
My point is that whether these small businesses have funds or not, they want growth to be instant. Some of these small businesses do implement measures for growth and then they quickly realise there is no instant results. So in most cases the measures fade away because no results are visible. Most real sustainable growth happens over time, similar to planting a seed today and only harvesting the crop in a future season and the crop may fail a few times along the way.
Being a coffee enthusiast myself, I can tell you that a good cup comes at a cost. I prefer to buy my beans from the roaster or a retail outlet that is directly affiliated with a local roaster, meaning they get freshly roasted coffee at least weekly. I do not buy the beans that are on the shelves on most supermarkets as they are in most cases guaranteed to be stale after a month from roasting date. Further I do not buy ground coffee as with that the freshness along with the taste is basically lost 3 minutes after grinding it. I buy beans and grind it myself, preferably with a hand manual grinder. An electric grinder is fine if it is a decent burr grinder, but the decent ones are usually the industrial ones and are rather expensive for the home user. You have the electric blade grinder as a cheap alternative but it gives you an inconsistent grind (coffee particles vary in size) and the heat of the rotating blades damages the coffee's taste. There is a reason to this madness, if done correctly you will get the most amazing and authentic coffee taste. Coffee should never be bitter. And you should never kill coffee with sugar! The reason people drink sugar in their coffee is exactly because it is prepared incorrectly and then tastes bitter.
