It’s a principle close to the heart of Eureka, who have been perfecting their grinder designs since their foundation in Florence in the 1920s, and who will be our grinder partners at Latte Art Live at The Milan Coffee Festival.
If the grind of your coffee is incredibly important to its final taste, then how do we decide the correct type of grinding?
It all depends on a seemingly endless list of variables; the type of coffee you’re brewing with, the roast, the brewing method and specific and so on. But as a general rule an espresso machine requires a very fine grind, whereas a V60 or an Aeropress would generally require a table-salt consistency (medium-fine), or depending on your recipe could require a medium-coarse or even coarse grind.
But what about the Moka Pot, beloved by the whole of Italy since its invention in 1933?
In this case you'll want a grind not quite as fine as espresso, but finer than you would need for a filter or French press. Water must be given the opportunity to pass in the right way through the "coffee panel", ie the puck of coffee present in the filter, to obtain excellent flavors in the cup, avoiding strong bitterness that can come from over-extraction.
The use of a high quality grinder is so important that in some cafeterias in Italy and and worldwide it is not uncommon to see two or three coffee grinders of the same type, just so the Barista is able to use several single-origins or different blends without having to contaminate the same filter.
At Latte Art Live the Eureka grinder will be a ready helper for each protagonist, and fast enough to follow the flow of drawings and demonstrations that will alternate on stage between artists and guest alike.
