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 required changes on time to achieve the perfect extraction. This equipment is simply marvellous for training purposes 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.
