A fine coffee grinder makes soil particles with the same and the right size. With this, we mean that the size of the coffee particles in the ground should match the coarseness setting of its grinder, fine or not. The size of the grounds made should also fit for the intended method of brewing, such as structured within the manu -manu -manu -manu
To test each grinder for our coffee grinder reviews, we first wash and dry all the components recommended by the manufacturer. We then set each machine to the appropriate level for grinding a coffee drip or automatic coffee manufacturers (again, as indicated by manu -manong). Sometimes the manu is lacking in specific directions. In this case, we will choose the middle coarse setting for grinding coffee, then drop it by another coarse level (from fine grind, like a espresso grind, to coarse grind). For example, if a grinder has 16 total coarse grinding settings (in the wake of 16 the most rough grinding option and 1 will be fixed), we will set it for rough level 9.
Watch it: Five things to know before buying a coffee grinder
Next, we weigh 10 grams of whole beans of coffee to grind. By default, our test beans are Kirkland Colombian Roast. This is the same beans we use for our coffee manufacturer tests. (There are no judgments, please.) When you grind a lot of coffee and espresso as we do, it will be paid to be economical.
Then we run our sample beans through the grinder. We also noticed how long the grinder lasts to grind the coffee beans. Next, we carefully collect the grounds, then sift them with a two-screen sieve for 60 seconds. For there, we use the Kruve Sifter System. Our original Kruve Two Unit came with two mesh screens of various sizes (800 and 400 microns). This step gives us a measure of grinding and grinding size of our sample. The Screw base Kruve Two has now been replaced and offered five mesh screens (300, 500, 800, 1,100 and 1,400 microns).
We use a Kruve Coffee sieve system to confirm the consistency of the grind size.
A good electric coffee grinder or hand grinder will produce yard, preferably with stainless steel blades, mostly between 400 and 800 microns in grain size (in our selected grinding settings ). Finally, we weigh the grounds collecting between two screens (800 microns top, 400 microns bottom).
A bad grinder will grind particles of various sizes, from large to small. Blade grinders are known to be known for this issue. Unlike a coffee coffee blade, a coffee grinder with steel or ceramic burrs usually produces grounds that are more equal to grind size.
In addition, we grind at least twice. From there, we can record an average best yield for each grinder.
