Description
The ChefWave NCM01B, sold as the Kava, is a capsule espresso machine built to take Nespresso OriginalLine capsules rather than a proprietary format of its own. ChefWave specifies an Italian 20 bar pressure pump, two programmable brew sizes at 1.3 ounces for espresso and 3.75 ounces for lungo, automatic capsule ejection into a storage container, a heat up time under 30 seconds and an automatic two hour shut off with standby mode. It measures 12.3 inches deep, 13.6 inches wide and 11.1 inches tall.
The proposition is straightforward: the same capsules as a Nespresso machine, from a third party machine at a lower price. That is legitimate. Nespresso's Original system is open enough that several manufacturers build compatible brewers, and the capsules themselves come from Nespresso and from many independent roasters. Whether the machine is worth choosing over Nespresso's own depends on what you give up.
Capsule Compatibility and What It Buys You
ChefWave states the machine is designed for Nespresso OriginalLine capsules or any other branded compatible capsule. That second half is the important part. The Original system has a large third party market: many roasters sell compatible capsules, and refillable stainless capsules exist for anyone who wants to load their own coffee.
That competition keeps the cost per cup down in a way Nespresso's newer Vertuo system does not allow, since Vertuo capsules carry a barcode the machine reads and the compatible market is far smaller. A buyer choosing between systems should weigh that more heavily than any machine specification, because the capsules are where the money goes over the life of the appliance. The capsule and pod range gives a sense of the choice available on the Original format.
Brewing and the Programmable Sizes
The 20 bar pump figure is the pump maximum rather than the pressure at the coffee. On a capsule machine that distinction matters less than on a portafilter machine, because the capsule holds a dose ground and tamped at the factory and the machine simply delivers hot water through it. Consistency is the point of the format.
Both sizes are programmable, at 1.3 ounces for espresso and 3.75 ounces for lungo as supplied. Programming is worth doing on day one: factory volumes rarely match a particular cup, and a machine that consistently overfills or underfills becomes a quiet daily irritation. Note that the 3.75 ounce lungo is smaller than the 5 ounce lungo on Nespresso's own machines such as the Pixie, though reprogramming closes that gap.
No Milk System
The NCM01B has no steam wand, no milk carafe and no frother. It brews coffee into a cup and nothing more. Published owner feedback confirms this is the most common complaint against it, which suggests buyers are not reading the specification before ordering.
Milk drinks remain possible with a standalone electric frother or by heating and whisking milk by hand, but that is a separate purchase and a separate piece of counter space. Anyone whose main drink is a cappuccino or a latte should budget for a frother from the outset. This is a category wide characteristic of small capsule machines rather than a shortcoming unique to this model; the Nespresso Essenza Mini has the same limitation at a higher price.
Cleaning, Shut Off and Daily Handling
Used capsules eject automatically after brewing into a storage container, and ChefWave states that the capsule container, the drip tray and the water tank are all removable and dishwasher safe. Dishwasher safe components on a capsule machine are a genuine convenience and not universal.
The two hour automatic shut off is considerably more generous than the nine minutes Nespresso uses on its own machines, which is a design choice rather than a fault: it means the machine is still warm if you come back for a second cup mid morning, at the cost of more standby draw. With a heat up under 30 seconds either approach is workable. Owner feedback notes the plastic water tank feels less substantial than the machine around it, and that the tank capacity is limited for a household.
Heat Up and Where It Sits Against Nespresso
A heat up under 30 seconds puts the NCM01B in the same bracket as Nespresso's own machines, which quote 25 seconds. On a thermoblock that heats only the water passing through it rather than a stored volume, those figures are all achievable and the difference between them is not something anyone would notice in use.
Where the machines genuinely differ is fit and finish, service network and resale. Nespresso supports its machines through its own channels and the brand carries a long record; a smaller manufacturer offers a one year warranty and less certainty beyond it. The trade is straightforward: a lower purchase price against a shorter, less established support path, on a machine whose consumables are identical either way. Anyone who values that record should compare the Nespresso Essenza Mini EN85R directly on price.
Errors in the Listing Data
Several fields on this listing are wrong. The item weight reads 1 pound, which is impossible for a machine with a pump, a heating element and a water tank; that is packaging data rather than the real weight of the appliance. The number of items field reads 3, which reflects this being sold as a bundle with a pod holder and cups rather than three machines. The filter type field reads reusable, which is meaningless on a capsule machine.
The manufacture year is given as 2018 alongside a first availability date of May 2019, which is normal for rolling production but means neither date tells you much about the unit you receive. ChefWave states a one year warranty covering parts and labour with a money back guarantee, and the machine is ETL certified, which is a North American electrical safety listing worth noting on a product from a smaller brand.
What the Specifications Do Not Settle and Who It Suits
The water tank capacity and the used capsule container capacity are both absent, and on a capsule machine those two figures determine how often you interrupt it. Also missing are the wattage, the brew temperature and the real machine weight. The listed dimensions of 12.3 by 13.6 by 11.1 inches are wider than the machine appears in photographs and are more likely the carton, so anyone measuring a tight space should confirm independently.
The NCM01B suits a black coffee drinker who wants Nespresso Original capsules at a lower entry price, values dishwasher safe parts, and does not need a milk system. With a large third party capsule market behind it, the running cost can be kept well below what a Nespresso branded machine plus branded capsules would cost. It is the wrong machine for milk drink drinkers without a separate frother, for a household making several drinks in a session, and for anyone who objects to the capsule model entirely. Those buyers should look at ground coffee machines across the espresso machine category, where the only running cost is beans and descaler.
