When talking about the best burr espresso grinders for the home it really comes down to only three machines. Of course you can purchase better grinders but they tend to be unrealistically expensive and are more suited to commercial settings such as coffee shops and restaurants. You can get grinders on a smaller scale that do just a fine a job and will cost you much less money. These are the burr grinders I'm going to be talking about in this article.
The most important thing you need to look for in a grinder is grind consistency. This is very important for one major reason. Imagine that you are taming your espresso grinds into your portafilter and the grind is inconsistent. You will end up with an uneven tamp, with one side of your filter more packed with espresso than the other side. When you come round to brewing the hot water will do what nature demands and it will always find the path of least resistance. This means that the water will head straight for the area of the filter where the grinds are larger. This will always result in a bitter and weak espresso since the finest grinds which contain the best flavor will remain untouched. This is why grind consistency is the number one thing you need to look for in a burr grinder for espresso. The best machine I would recommend for this quality is the Baratza Vario which uses ceramic burr grinder, something that not many other machines use.
Next you need a machine that operates in a stepless fashion. With steps, you can only choose your grind settings between numbers. So for example you can have your grind at setting 5 or setting 6. But what if you need something between grind setting 5 and 6? What if you really need to fine tune your grind to make that perfect espresso? Well for this, you really require a stepless grinder that will allow you to choose 5.1 or 5.2 etc. For this, once again I will recommend to you the Baratza Vario grinder as it is the closest thing to a stepless design.
Grinders that are easy to clean are also an advantage, as we all know, those coffee grinds can get everywhere. You need to be able to take your machine apart every now and then for a thorough cleaning so a nice and simple design is a major positive.
Once again, I would recommend the Baratza Vario as one of the best burr espresso grinders available for the home.
I hope you can find a quality grinder to make that perfect espresso!
