Barista Pro insert baskets are carefully crafted and 100% made in Italy by IMS. The AISI steel 304 is food-safe certified and specifically designed for the optimal production of espresso. With holes made with a precise diameter and number of holes consistent size-to-size Barista Pro precision insert baskets ensure homogeneous extraction and a balanced cup of fresh espresso! NANOQUARTZ coating on most of the precision insert baskets shown here is a non-stick coating that increases your precision insert basket's resistance to corrosion and makes it easier to clean as well.
These insert baskets are all compatible with the most common sized espresso machine groups, 58mm. However, take note of the depth of the insert basket as many spouted portafilters cannot fit baskets 18g or 25g in size due to the depth of the interior of the portafilter where the precision insert basket installs. Sometimes referred to as triple insert baskets, you might want to consider using a bottomless portafilter which is also a great training tool to monitor extraction closely and identify where or why you might be experiencing channeling as well.
