NCD Nucleus Coffee Distributor, the original distributor for espresso. It shows considerable signs of use, but it doesn't affect its functionality, so there's no problem for those who don't mind. No box included. I will be listing coffee-related goods one after another in January 2026, so I would be grateful if you would check them out. The following is quoted from the seller's page: NCD evens out the distribution within the basket after dosing (grinding coffee beans). If the density of the coffee powder in the basket is not uniform, the extraction will be uneven, and sufficient extraction cannot be achieved. (This is called channeling.) Traditionally, the surface of the coffee powder was leveled by hand, but this required skill and had low reproducibility. NCD is a distributor tool designed to easily and evenly distribute the coffee. Nowadays, dosing + leveling is sometimes collectively referred to as "distribution." NCD is the only product that has an international patent for a distributor tool. Extraction with uneven powder in the basket will result in uneven extraction. The NCD Nucleus Coffee Distributor was created to solve this problem. By using NCD, you can even out the distribution within the basket. 【Usage scenarios】 ◎ Ideal for VST and IMS baskets ◎ Lack of leveling skills ◎ Leveling takes a long time ◎ Unevenness due to multiple people extracting ◎ High number of cups served per day ◎ Sour, bitter, or unbalanced taste × Baskets smaller than 57mm × Excessive amount of powder for the basket 【What happens when you use it?】 ・Extraction uniformity improves ・Anyone can achieve an average taste ・Acidity, bitterness, etc. become less pronounced, resulting in a better balance ・Leveling work is faster, increasing service speed ・Prevents channeling (incomplete extraction)
