Coffee Weighting Done Right
Espresso coffee digital weighing scales are an essential working tool for the discerning barista.
In order to set the grind on your espresso grinder, it is necessary to know how much coffee is being ground and for how long. It should take approximately 7 grams, 18-23 seconds to pour 30cl (1fluid oz) depending on the coffee. Pure arabica coffees require a longer pour and usually more coffee than an espresso blend.
You should weigh 7 grams (14 grams if using a double basket) into a small container and pour it into a single shot 7-gram filter basket. This should take 18-23 seconds for a 30cl espresso shot.
If it pours too fast, then you have to make the grind finer.
If it pours too slow, you have to make the grind more coarse.
No matter what length of time it takes to pour an espresso shot, you will always need to know how much coffee was used each time, and the best way to do this is to weight it.
