Choosing an Espresso Coffee Grinder Espresso requires a very fine consistent coffee grind Many people are focused on the espresso machine or the quality of the beans however a highquality grinder is equally as important A stepless adjustment knob enables you to make micro adjustments with precision This is preferred over an adjustable step that may include numbers or hashes to indicate the desired grinding degree Type of Burrs When selecting an espresso grinder the type of burrs used is a key factor Grinders that are specifically designed to make espresso use larger motors and a unique burr set to produce a finer grind which is crucial to make a quality cup of espresso The standard grinders used for French press pour over or drip coffee do not create a fine enough grind for espresso The two most common types of burrs found in grinders are conical burrs and flat burrs Both have their pros and disadvantages It all depends on the type of coffee you prefer to brew and how Flat burrs tend to have a more consistent grind and can result in a cleaner and clearer cup of coffee They do however generate more heat while grinding and may leave stragglers which can alter the flavor of your coffee Conical burrs on the contrary can accommodate a wider range of sizes for grinding From coarse for French presses to extremely fine for Espresso Additionally they are generally less difficult to clean than flat burrs There is some debate as to the difference between conical and flat burrs are more appropriate for espresso but it largely comes down to personal preference and the type of coffee youre making Anecdotal evidence indicates that flat burrs are more clear in flavor whereas conical ones have a greater body However this is not always the case The RPM revolutionsperminute and the size of a mill will also have an impact on the flavor profile The type of burrs you choose to use can influence the overall quality of the grind but other aspects are equally important to take into account The motors RPM for example can generate heat that can affect your coffees taste The noise level and grind retention of the grinder may also play a major role in the quality of your espresso These factors are typically more influenced by the grinders motor than its type of burrs The Burrs Size Burr size is a key factor in the quality of espresso The more fine the grind the larger burrs Smaller burrs will produce an unfiner grind that is not ideal for espresso The size of the burrs affect the speed at which the grinder grinds the coffee Larger burrs require a larger motor and they can be noisy However they can grind more quickly and produce much less heat Less heat can result in less variability on the size of the grind and an easier extraction The shape of the burrs will also affect how the beans are grind Flat burrs produce an even grind for instance They also are known to be quieter than conical burrs however this is contingent on the grinders motor and other elements It is crucial to select a flatburr grinder that has a good design and quality materials They can reduce friction which can cause the ground to clump together and produce static electricity within the grinder They also reduce the heat produced during grinding which can affect the quality of the espresso that is produced When choosing a flat burr grinder make sure you choose one made of a sturdy material like titanium or stainless steel These kinds of materials are strong and are not susceptible to heat buildup during grinding They are also simpler to clean and are able to withstand the repeated pressures that are often applied to a mill during use The type of grinder that you choose will have an impact on the taste and quality of your espresso The burrs have to be aligned properly to ensure that they dont overlap or hit each other This can lead to uneven ground sizes and can cause damage to the grinder If you notice that the burrs are not aligned correctly it may be necessary to contact a professional If your grinder is used regularly the burrs could become misaligned over time This could lead to the creation of a ridge that can affect the consistency of your ground and the quality of your espresso If this occurs its best to replace the burrs by one specifically designed for your specific grinder SSPs 64mm Unimodal Red Speed Burr sets for instance can be used to replace the original burrs on numerous popular espressofocused grinders such as the Mazzer Superjolly and Option O Lagom P64 The Burrs Weight While its good to consider burr size and shape but the weight of the burrs is important The heavier the burrs are the greater the force exerted by the grinder on the coffee beans This will affect the rate of grinding and ultimately the size of the coffee particles produced The size and weight of the burrs will determine how finely a grind will be produced In general a more fine grind will produce a larger particle size distribution and the coarser grind will result in a smaller particle size distribution This is why its important to be aware of the purpose of the burrs when choosing a coffee grinder wwwcoffeeeuk that is of highquality will result in more uniform sizes of particles which are crucial for regular extractions In addition the sharper the burrs are the less likely they will get worn out over time A dull burr wont cut coffee beans precisely and will cause them to squish This can lead to more clogging increased heat buildup and slower grinding rates Some wear and tear on the burrs is normal However grinders that have poor quality burrs could quickly become unreliable This is especially true when it comes to a commercial coffee grinder that is frequently used It is important to keep a burr grinder that is of good quality You can test the performance of the grinder by running a small amount of fresh or roasted beans through it Then take a look at the results of the grinds that youve placed in your hand If the burrs are dispersed and strewn about its time to replace them This will not only enhance your drinks but it will also extend the life of your grinder and ensure that it is performing at its best Burrs can be adjusted Burrs It is essential to select a grinder that will produce a uniform distribution of grind size This will allow you to make espresso shots with the same flavor and balance each time To accomplish this you should select a grinder with an adjustable upper burr This will allow you to customize your grind The burrs can be adjusted to alter the consistency of your grind The adjustability of the upper burr is normally accomplished by turning a lock ring that holds the upper burr in its place This ring can either be turned clockwise or counterclockwise to create a more fine grinding and vice versa to produce the coarser grinding This is particularly useful for setting your grinder to the proper size for espresso You should always be aware of the fineness of your grind is before brewing because it could dramatically affect the flavor of your espresso Some prefer a finer grind for their espresso as it adds more flavor to the shot and also reduces the flow of water which is required to make espresso shots However you should note that a finer grind can be more difficult to work with as it is more likely to block the portafilters It is recommended to select a coarse or medium grind when using your espresso grinder for coffee The lock ring lets you to quickly switch between the two grind sizes When you are looking for an espresso machine you must also consider the amount of noise it produces You want to choose an espresso grinder that is quiet but not too quiet as this can negatively affect the quality of your espresso You can test the noise by putting your ear in the vicinity of the grinder and listening for an humming If you hear any humming youll need to think about another grinder since it will be too noisy for you to use
