The most affordable grinder and probably the one most of the people start is a blade grinder. It uses the sharp edges of the blades to cut and crash the beans.
The longer you are using it, the thinner will be the coffee grounds but this brings inconsistency. This is also the main problem of this grinder. That in the same grounds you have very thin ones but also coarser coffee grounds.
The burr grinder is crushing between 2 surfaces the beans. One surface is moving while the other one remains still. Changing the distance between the burrs, is defining with accuracy how fine the grounds will be.
In the burr grinder category there are 2 different types. The conical and the flat burr grinders and they get their names from the shape the burrs have. The conical ones are creating less heat while grinding while the flat ones are famous for making espresso grounds.
As already mentioned in the beginning the biggest negative of a grinder is the inconsistency cause if you have both thin and coarser grounds while making your coffee, they are releasing their flavors in different timings. The thinner are faster and the coarser are slower.
The ideal grind size depends on the brewer you are going to use. But it stays between medium grind and medium-fine grind. The medium grind resembles sand and it is probably better for the drip method while medium-fine grind resembles to table salt and it is better for pour over. When making your coffee though or when you get new coffee beans most of the times, you need to play a bit with the size and find the proper one (the one you enjoy more) for your brewer.
ZP6 seems to give very good separation of flavours, clarity to a cup. It doesn´t produce lots of fines, so it doesn´t have a lot of body the coffee. Grinding finer though, could give body to your coffee. It is recommended for light to medium roasts.
Comandante c40 is more expensive than ZP6 and seems to have not an even grind comparing to ZP6.
X-Series: seems to give sweetness, body and balance in a cup
1zpresso seems to be a smooth grinder in operation and it includes also cleaning tools. Very quiet and easy to adjust as well. It needs approximately 23 sec. for 30g of coffee.
Timemore gets quite close to 1zpresso but it is more compact, so ideal for travelling.
For regular grinding more than 60g, an electric grinder is definitely recommended.
Fellow Ode Gen 2 is one that is highly and often recommended for pour over. Very consistent grinding and no static cling.
