Are Coffee Grinders More Important Than Coffee Machines?
You may have been thinking about purchasing a
traditional espresso coffee machine and put all your budget towards your dream
coffee machine. However, it would be foolish of you to overlook your coffee
grinder. Your coffee grinder is more important than the coffee machine. In
simple terms, a coffee machine passes hot water through coffee grounds to
create flavour. The magic happens in the grinder and here is why.
The Job of a Coffee Grinder
- Depending on the type of grinder, a blade or burr,
coffee beans will be ground in different ways.
- Blade grinders slice the beans up creating ununiform
grounds, which is not the best extraction process.
- Burr grinders work in a slightly different way. This
type of grinder crushes the coffee beans between two plates creating uniform
grounds. This form of extraction normally produces better tasting coffee.
- To match the brewing method, you will need to
adjust the distance between the two plates to create a finer or courser coffee
- There are two types of coffee grinder, an on-demand
coffee grinder or a dosing grinder. The on-demand coffee grinder is perfect for
freshness as it grinds the coffee for when you need it. Dosing grinders are
good for busy situations, where you can grind a batch of coffee in advance and
use it for when it’s needed.
Why is the Coffee Grinder So Important?
The purpose of grinding coffee beans is to break
them down into smaller parts so that water can pass through the beans and
extract compounds from the coffee. To get the best flavoured coffee and most
effective extraction, you need to have coffee ground to a consistent standard.
This is because a finer coffee particle will take a shorter time to brew
compared to a large coffee particle. Therefore, if the coffee is ground too
fine, the smaller coffee particles will be over extracted, and the if the
coffee is ground too course the large particles will be under-extracted. Its
important to grind your coffee to the correct specification for your specific
method of coffee brewing.

What Does It Mean by Over-extraction and
As coffee is being brewed, the length of time that
the water is in contact with coffee could lead to over or under extraction.
This will heavily influence the flavour of your coffee. Under extracted coffee may lead to your brew
being sour and over-extraction could cause your coffee to taste bitter.
Overall, you will need to experiment with the
different grind sizes to get the ideal coffee for you. Not everyone likes their
coffee the same, a slight tweak may allow you to fit a wider audience. A key
thing is to ask customers their feedback on the taste of coffee, you want these
people to return to your coffee shop. Ensuring that customers are happy with
the coffee you’re producing, Is the most important thing!
