You would be amazed at the various kinds of factors that can end up having a relatively strong impact on how your coffee is going to end up tasting in some way, shape or form. The first factor is of course the bean that you choose, but that is likely something that you have already familiarized yourself with at any given point in time. Perhaps even more important than your choice of bean is how much you choose to grind it, and this is something that countless people tend to get wrong each and every day.
A big part of the reason why that is the case has to do with the fact that they assume that the best espresso machine under $200 will be able to utilize any coffee beans that they enter into it regardless of the kind of grind they have opted for. Suffice it to say that if your grind is too coarse, your espresso will start tasting really watery and it will not have any kick to it at all for the most part.
That said, you should be careful about grinding it too fine as well. That might result in coffee grounds leaking into your espresso and getting into your mouth which would really ruin the experience for you in a way that you would regret. You should use coffee that is on the finer end of the spectrum but that still has a bit of chunkiness to it. That creates the perfect environment for the espresso machine to do its job and it will result in a creamy, delicious cup of espresso that you wouldn’t be able to get enough of.
