5 Things to Think About Before Buying a Coffee Grinder
With such a diverse range of coffee grinders available in the market for everyday coffee shop equipment, ranging from as little as AED1k to a hefty AED18k, one can't help but wonder what accounts for such a significant price difference.
By default, many aspiring cafe owners believe that the Espresso Machine is king and that an espresso grinder is a simple tool that is part of the coffee bar. Nothing could be further from the truth. Aside from the fact that it is a tool, the grinder is an essential component in the coffee preparation process.
Whether you're making espresso or filter coffee, it can mean the difference between a good cup and a great cup.
In the first instance, the strength of any coffee grinder is its ability to maintain the smallest deviation between the coarsest and finest particles of a dose. The most efficient grinder can provide extremely precise and accurate grind size.
Here is a quick checklist of things to consider before buying your next coffee grinder.
Volumetric or on-demand?
The first thing to consider is that, according to well-known studies, coffee can lose up to 60% of its characteristic aromas after just 15 minutes of grinding. This means that only coffee shops with a high volume of coffee cups consumed each day can afford a volumetric coffee grinder. Those shops grind continuously, and coffee will only be ground for a few moments in the grind dispenser. Even so, it will lack the aromatic richness of freshly ground coffee. As a result, if you want to serve your customers a full aromatic cup of coffee, on-demand grinders are the only option." But my customers can't wait!" you'll protest. The real question is, can you really persuade someone to wait 3 seconds longer (three seconds!) than the average time required to grind a quality coffee? Are we really talking about three seconds for the customer to pick up the sugar packet?
Why grind by weight rather than time?
If you enjoy your job and are particularly concerned with providing a great cup of coffee to your customers, you will be aware that sometimes the result in the cup will differ from expectations, even if you have correctly set the particle size of your Coffee grinder. You have likely served dozens of excellent espressos in the morning, then returned from your lunch break to find over-extracted or under-extracted coffees without changing anything in the meantime. This is because the granulometry of the ground coffee must be adjusted several times per day to allow it to adapt to changes in environmental conditions.
Temperature Control Is Critical
When selecting a coffee grinder, this is an especially important factor to consider. Roasted beans contain a significant amount of oil, and as we all know, oil is extremely sensitive to temperature changes, which alter its viscosity. The burrs heat up as they turn and grind, heating the coffee that passes through them. The turning of the engine generates heat (a lot of heat! ), which warms the grinding chamber. The temperature increase is influenced by the electrical components within the Coffee grinder body.
Purchasing a High-Quality Grinder
By now, you've realized that the factors to consider before purchasing a coffee grinder are numerous, as numerous variables contribute to the realization of a good grinding. Fortunately, the importance of the grinder in the world of coffee is growing, and there are more efficient grinders on the market.
The most important point to emphasize here is that spending money on a good coffee machine for cafe is pointless if its performance is completely negated by a bad grinder! We can't stress this enough: coffee quality, grinder, and coffee machines (as well as the water used, to be honest) are all equally important if we want a good cup of coffee. So why do we insist on treating the grinder as a supporting character?
