![]() The average coffee drinker will be grinding for 1-2 shots at a time, so there’s little chance of the heat from the burrs affecting the coffee. The heat generated by steel burrs is something to consider, but it shouldn’t be the deciding factor. They will wear down over time, but you won’t notice the difference for a home grinder for many years. Steel burrs, on the other hand, won’t crack and are much sharper when new. Ceramic burrs can be prone to chipping, but apart from that they are much more durable than steel and stay sharp for a lot longer before they need to be replaced. The question of ceramic vs steel burrs is one that professionals will take very seriously, but it’s not quite as important for anyone buying a home espresso grinder.Ĭeramic burrs are chosen for commercial operations as they generate practically no heat during the grinding process. If you’re using a manual grinder, a faster grinder means less of a workout to get your freshly ground coffee. The less time it takes to grind, the less heat it will generate, preventing any change in the flavor. Larger burrs have more surface area, which translates into more coffee beans ground at a time. The size of the burrs refers to the diameter, and larger is better. However, this positioning also leads to more ground coffee left in the grinder. Due to the horizontal positioning, a flat burr grinder is much more consistent and produces fewer fines. The shape makes them highly efficient, which makes them suitable for manual grinders, but it also means they’re often quieter in an electric grinder.įlat burrs require more force to grind your coffee beans, so you’ll most often see them in automatic grinders. Serious coffee connoisseurs will probably have their preference, but we can assure you that both a flat burr grinder and a conical burr grinder will provide a consistent grind if you buy quality.Ĭonical burrs are the most common you’ll come across. The two burr shapes you’ll encounter are conical burrs and flat burrs. You don’t have to aim for the largest number of grind settings as a hard rule, but if you’re on the fence, pick the one with more settings. There is a minimal range of grind sizes that are appropriate for espresso, but it’s better to have the option to customize than not. Having said that, there’s no real benefit to having a grinder with fewer settings. Even stepless grinders, which in theory allow you to make infinite adjustments, have a minimum and maximum grind size. There is no correlation between the settings on different grinders – the coarsest setting on one won’t match that of another, and the increments between grind settings won’t adjust the size by the same amount. If we wanted to make this short, we could tell you that grind settings are better, but it’s unfortunately not quite as simple as that. Blade grinders chop the coffee beans rather than grind, resulting in uneven coffee grounds. The accuracy and consistency required are why we don’t recommend blade grinders. For example, light roasts extract more slowly, so you may want to grind slightly to extend the extraction time ( 2). On a day-to-day basis, you’ll find that different coffee beans require different grind sizes to get the same level of extraction. For a start, all espresso machines will vary a little in how they work, and you’ll find that what worked for one machine will be entirely the wrong grind for another. The fact is, there is a whole range of other variables that help define the grind size you need. You might be wondering why you need so many grind settings if brewing espresso is so specific. Too long, and your shot will be bitter and lacking in complexity. ![]() Too short, and you’ll end up with an under-extracted, sour coffee. You might not be concerned about your standing with the SCA when you pull a shot of espresso, but a change in brew time has consequences for the flavor. A coarse grind will allow water through at a much faster rate, while an excellent powder will slow the extraction speed and even decrease the shot volume. The grind size comes in is its impact on the brew time.
