The Bottomless (Naked) Portafilter is a must-have tool if you want to watch the perfection of coffee extraction at its best. A bottomless portafilter clearly exhibits how the extraction is progressing, so that you could make the required changes on time to achieve the perfect extraction. This equipment is ideal for working on your grind and tamp since you can easily notice if channelling occurs - a sign of uneven tamping or grind levels. It is excellent for pulling a perfect shot of espresso every time. 

Constructed out of chrome-plated brass and equipped with a beautiful wooden handle. Does not include filter baskets or springs.
