The 58mm has become an invaluable tool for espresso training. Novice baristas and alike can now instantly and visibly determine whether their grind, dose and/or technique is on or off. Valuable clues to informed trainees where work may be needed. In the hands of an experienced barista using espresso beans, the bottomless handle will yield 50% or more crema. Why? Your espresso will not touch any surface other than the bottom of the coffee handle basket. There is no bottom and no spout. This leaves the tiny air we look for in the perfect shot intact. Also, since there is no spout, espresso can be poured directly into the cup for drinking in most cases. Our product allows the barista to immediately deduce whether the correct compaction technique has been achieved. If the extraction is tilted to one side or the other, an incorrect angle used when tamping. If you see a rogue stream of espresso from the bottom of the basket, your 58mm handle may be flattened or unevenly dosed. The usual standard for commercial and prosumer machines, dual shot filter baskets typically hold 16-22g of ground coffee. This is probably what you want to use most . The removable double cup basket is easy to deep clean inside the 58mm Alloy exposed handle. Food grade and dishwasher safe non-pressurized basket.
