WHICH GRIND SHOULD YOU USE
When grinding your beans here are a few pointers to hopefully help towards your perfect brew. If your method of brewing coffee has a short contact time your grind should generally be finer, however methods that bring your coffee in contact for longer periods of time require a coarser grind. Please note this does also depend on your personal preference, if you find your coffee is not strong enough to your taste, try a finer grind. If your coffee is too bitter and strong for your liking, try a coarser grind. Everyone has their own preference when it comes to most things including coffee, but here is a quick guide to the recommended grind for different brewing methods available.
This is brewed in a ibrik and is a very flavoursome and strong way a making coffee and requires a very fine grind due to its short contact time.
Espresso coffee is a brewed through using pressure (approximately 9 bar) forcing water through fine compacted coffee grounds.
The AeroPress is a single-cup manual coffee maker, similar to a French press in design and use. due to its brewing technique a fine grind size is recommended.
Siphon coffee brewers use pressure to force water into a chamber holding the coffee grounds. Once the steep has finished, heat is removed, which creates a vacuum in the lower chamber and pulls the water through a filter. This method calls for a medium to fine grind size.
Pour-over brewers come in an array of different sizes and shapes. While different brewers require varying grind sizes to control the flow rate of water, most pour over methods call for a medium to medium-fine grind.
STOVE-TOP ESPRESSO MAKER OR MOKA POT
A stovetop espresso maker or Moka pot is a coffee maker which uses steam pressure to force water upwards through a filter basket full of coffee grounds. The contact time is quite short, but the pressure (approximately 1.5 bar) is a bit higher than your typical manual brewer. It calls for a medium grind size.
SINGLE CUP COFFEE MAKER
A single-cup coffee maker, such as a Keurig or Verismo machine, is a drip brewer method, similar to the commercial drip brewers found in cafes. The contact time is fairly low, meaning it calls for a medium to medium-fine grind size, comparable to that of table salt.
DRIP COFFEE MAKER
Drip coffee is what you typically get from a cafe or coffee shop and is one of the most common types of coffee making appliances on the market. It's made in large batches and contact time is dictated by a small hole in the bottom of the brewing basket, so recommended grind size varies between medium-coarse to medium.
The French press is an immersion brewer. Water is added to coffee grounds and allowed to steep for several minutes before straining out the grounds. This method calls for a coarse grind setting.
Cold Brew, unlike other brewing methods, is done at or below room temperature and takes between 12 and 72 hours. Due to the low temperature, the extraction rate is low, regardless of grind size. A coarse or extra coarse grind size is recommended, as it's easier to filter. A finer grind size will work just as well (with a slightly shorter steep time), but can cause the final product to appear a bit cloudy.
