Description
The REVOTRA MK-B-DCM01 is a 12 cup programmable drip machine with a 1.8 litre glass carafe, an LED display, a 24 hour timer, brew strength control, a small batch setting and a mode the listing calls iced coffee. At 6.7 inches wide it is one of the narrower 12 cup machines available.
The arithmetic in this listing holds up, which is worth noting because it often does not. A 1.8 litre carafe is around 61 fluid ounces, and 12 cups at the standard five ounce carafe measure is 60 ounces. So the capacity claim is honest, and a full pot is four or five mug sized servings rather than twelve.
The PROG Button
The most distinctive thing about this machine is how its modes are selected, and the listing is unusually specific about it. Press the PROG button twice for the one to four cup setting. Press it three times for the iced coffee mode. The same button also handles the timer.
That is a lot of behaviour on one control, and it is worth knowing before the first morning rather than discovering by accident. Multi press interfaces are cheap to build and awkward to live with, because there is no way to see which mode you are in except by counting what you pressed. Anyone who wants each function on its own control will find that on machines with a fuller panel, such as the Cuisinart DCC-3200.
The Small Batch Setting
The one to four cup mode solves a genuine problem on any large machine. A brewer built to saturate enough grounds for 12 cups moves water quickly, and a small bed of grounds does not slow it enough, so a single mug comes out weak even with the correct ratio.
A small batch mode reduces the flow rate to compensate, so the water spends the right amount of time in contact with a smaller bed. It is the feature that makes a 12 cup machine usable on a weekday when only one person is drinking, and its absence is why cheap large machines are often disappointing for a single cup.
The Iced Coffee Claim, Examined
The listing describes pressing PROG three times for what it calls a perfectly balanced cold brew. That wording needs unpicking, because two entirely different things are being conflated.
Cold brew is a cold water steep lasting twelve hours or more, and the low temperature is what produces its characteristic low acidity. A hot drip machine cannot make cold brew, because it heats the water. What an iced mode on a drip machine can sensibly do is brew a shorter, more concentrated volume so that melting ice dilutes it back to normal strength rather than to weakness. That is a useful function and it is almost certainly what this button does, but it is not cold brew and calling it that is misleading. If you want the real thing, the cold brew makers we cover do it properly for very little money, and a machine like the Ninja CM371 at least separates its over ice setting from its cold brew setting.
Brew Strength and Programming
Brew strength control offers a milder or bolder result, which on a drip machine works by varying the flow rate so water spends more or less time in contact with the grounds. It is a real control and independent of the ratio.
The 24 hour programmable timer covers delay brewing, so the machine can start before you are awake. Auto shut off is included, and a keep warm function holds the carafe for up to two hours. Two hours is shorter than the four most machines offer, and that is arguably a feature: a glass carafe on a hot plate keeps cooking the coffee, so a shorter window means less stewing. Pause and serve lets you take a cup mid cycle, with the standard caveat that the first part of a brew is stronger than the last.
Filters and What Is In The Box
The included components are listed as the coffee maker, a glass carafe and a user manual. There is no filter in that list, and the filter type field records Basket, which describes a shape rather than a type.
Taken together that means you supply your own filters and that no permanent mesh filter ships in the box. Basket shaped papers for an 8 to 12 cup machine are the ones to buy, and the disposable filters we cover include that size. Do not order cone filters, which are a different shape and will not sit properly. The filter basket itself is described as removable, which makes disposal and rinsing straightforward, and an anti drip system stops the basket dripping when you pull the carafe.
Size, Build and Listing Notes
The recorded dimensions are 8.6 inches deep, 6.7 inches wide and 12.6 inches high, with an item weight of 4.38 pounds. That width is genuinely narrow for a 12 cup machine and makes it a candidate for a gap where a wider brewer will not fit. Four and a half pounds is light and indicates an all plastic body with a stainless effect facing.
Two notes on the listing itself. The special feature field mixes real features with a capacity figure, listing 1.8 L alongside the programmable and iced coffee entries, which is a specification in the wrong column. And the manufacturer description uses decorative bold characters for its headings and is cut off partway through its final bullet, so whatever it was about to say about cleaning is lost.
What the Specifications Do Not Settle
No brew temperature, which is the figure that separates a good drip machine from a weak one and the one no manufacturer in this category publishes. No wattage. No brew time for a full carafe. No description of the shower head or how evenly water reaches the grounds. No warranty term. No explanation of what the iced coffee mode actually changes, whether that is volume, flow rate, temperature or some combination.
The first availability date of November 2024 and the recorded manufacture year of 2024 agree with each other, which is welcome, but they also mean this is a new product from a brand without a track record. The body of published owner feedback is correspondingly thin, and nothing yet indicates how the heater and the switchgear hold up over several years.
Who It Suits
This suits a household that wants a full size programmable machine in a narrow gap and does not want to spend much. The small batch mode, the strength control and the delay timer cover what most people actually use, the two hour keep warm window is kinder to the coffee than a longer one, and the capacity claim is honest.
Look elsewhere if you want cold brew, because this machine does not make it whatever the description says. Look elsewhere too if you dislike multi press controls, or if you want a machine with a long service record behind it. And as with every glass carafe on a warming plate, a thermal carafe machine from the drip coffee maker range is the right answer if the pot regularly waits.
