Preparing coffee like the professionals do requires a little science. the Golden ratio It’s the perfect balance between coffee and water and a great place to start if your current strategy is just to get high.
In addition to determining measurements, there are some basic pieces of equipment that help extract the most flavor from your beans.
If you’re grinding at home, as most experts suggest, using whatever grinder you have in your kitchen can harm the final product. Having the right machine to grind your beans evenly gives you more control and helps you get a more balanced drink.
A grinder gives you maximum control over the beans you use to make a cup of coffee – it’s one of the most important coffee tools you can own.
“A burr grinder gives you maximum control,” Kalina Teoh confirms. Teo is the co-founder and education director of New York Coffee Projectpraises burr grinders because they “give you the ability to brew coffee exactly the way you want it.”

What is a burr grinder and how does it work?
Unlike a blade grinder, which grinds coffee beans by slicing them, burr coffee grinders crush them. Burr grinders use two abrasive or toothed discs or plates, known as burrs, that rotate either parallel to each other or concentrically.
Mills are able to grind grains evenly and with fine coarseness.
When the coffee beans are squeezed together, they are crushed to a pre-set size that is determined by the distance between the two blades, and is adjustable to suit the type of coffee being prepared and personal preference.
When using a burr grinder, coffee beans are crushed to a pre-determined size – which is more consistent than a blade grinder.
Why is a blade grinder better than a blade grinder?
“With a blade grinder, there is no way for us to guarantee how the grains are moving inside the grinder, which basically acts like a blender,” Teoh says. “You’re basically chopping the grains and cutting them at different angles,” as they fly randomly into the grinder chamber.
No matter how long you run the mill, you’re still likely to get a wide range of particle sizes in the final grind, “from really fine powder sizes to really large rocks,” she says.
Blade grinders do not grind at all. Instead, they cut the beans at different angles, grinding them unevenly.
In comparison, the primary purpose of burr mills is consistency, as the shape of the mill forces the grains to move between the burrs in a specific way. (One of two specific methods, explained below.) “You’re always going to have slightly different particle sizes, no matter what type of grinder you use, but for a burr grinder, that range is much smaller compared to a blade grinder,” says Teoh.
Flat mills vs conical mills
There is a slight difference in particle size distribution between conical and flat grinders, but both can deliver professional-level results.
Boring mills come in two forms: Flat burr mills, where the circular-shaped burrs are stacked on top of each other in a parallel manner. The beans are then inserted into the inner circle and pushed between the ridges before emerging on the sides. Conical mills consist of one ring-shaped burr and one conical burr, working in combination, the grain passing between them and exiting through a chute below.

“Both flat and conical burrs are capable of giving you great results, as long as you are able to understand how to grind your coffee,” Teoh says.
Burr grinders of either model may be pre-calibrated for specific styles of coffee, such as pour-over or espresso, or may have a wide range of grind sizes. However, everything will be adjustable, allowing you to fine-tune the grind to achieve the flavor you want in the final drink.
There are two types of coffee grinders you can choose from: burr grinders or flat cone grinders.
There is a slight difference in particle size distribution between flat and conical mills, which mainly comes down to a matter of preference. “A flat burr gives you a grind where the majority of the particles after grinding are a constant size, and with a conical burr, it gives you two sets of grind sizes, with one set a little finer and the other set a little coarser,” Teoh says.
The argument behind a conical grinder is that this gives you a more complex shot of espresso due to there being two different extraction rates; However, “the Specialty Coffee Association did a lot of research and blind tasting and decided it was too difficult for people to tell the difference.”
The key to choosing a burr grinder is to choose one that suits your use, as some grinders are pre-calibrated to produce a specific combination of grinds for a specific style of coffee: extra fine powder for espresso or large, sea salt-sized grinds for pour-over or French press. Some large capacity grinders offer a wide range of settings for different types of coffee.
Burr Grinders: Good and mid-cost brands
You don’t have to spend a lot of money to buy a coffee grinder, but make sure you choose one from a reputable brand.
Hole grinders come in either electronic or manual models, and as with any kitchen appliance, you can spend a lot of money on one, but you don’t necessarily have to. Teoh says she uses a variety of different grinders with Coffee Project New York; Among the professional brands she loves, such as Mahlkönig and Victoria Arduino, there are several brands she recommends for home use:
Beans are also important
The main purpose of grinders is consistency, so it’s worth having one in your kitchen if you’re a coffee lover.
If you’re thinking about getting serious with a grinder, it’s of course important that you do too Get serious about your beans. Your average supermarket whole bean probably isn’t worth the splurge. In particular, for burr grinders, especially hand-crank models, the darker the roast, the crisper and easier it grinds. So, consider your preferred roast in your purchasing decision.
As for improving consistency and control with your grinder, “buy coffee from your local roasters,” Teoh advises. “They usually roast every day of the week, then serve you fresh coffee. The fresher the coffee, the better the aroma and flavor that results.”
