But everyone is terrified of mokasplosion.
I’ll admit, the prospect of a pressurized vessel of boiling water is a potent reminder for precautionary thinking.
The custom where I am at is to load the moka pot with a grind and quantity that produces a significant barrier to the flow of water.
The alert that the brew is finished is the sound of the boiling hot water and steam spraying the coffee through the standpipe into the upper chamber, and it is absolutely under steam pressure, I’d say around 5 to 10 psi.
When the liquid water is low enough that it doesn’t get picked up by the lower tube, you get a significant outflow of pure steam hissing through the standpipe nozzle, and then it’s quiet, as the bottom chamber is now completely dry, as are the grounds when you dump them out.
It could be that if you use a coarser grind or less coffee than is customary here, flow restriction does not occur, and the pressure of the heated air and water vapor is enough to push out all of the water through the coffee without reaching 100c (should only take about 1/6 psi for a flow overcoming gravity to that height) but if you used that method here your coffee would fall under heavy criticism.
The violence with which the flow jets into the upper chamber and the volume and aroma of the steam serves somewhat as a social signal as to the “quality” of the coffee, so there is a strong incentive to heavily load the pots here.
Legends of exploding pots are common, as is precautionary disposal of pots whose threads have become excessively worn.
But I still have no first hand knowledge of anyone witnessing an explosion or even an over pressure venting event (there is a small pressure relief valve on the side of the vessel)…. So I suspect that the risk is not that high.
He, like many others, do little more than just read spec sheets.
I like his car related content though, reckless driving notwithstanding
Another high-hour channel for me is Petter of Mentour Pilot.
As an Australian, those two guys accents their way of framing things are like mum’s lullabies.
That is not to say that I personally take all or most of Hoffman's suggestions at face value. It's abundantly clear that the level of nuance he considers in coffee is not relevant to me. But I do tend to see him applying a much more objective level of rigor to his reviews than many other content creators.
Coffee is more niche. It makes more sense for "objective credibility" to play a role there.
I have great respect for his integrity and body of work
Also has very good books. So, totally not the average youtuber/content creator out there.
He's mentioned modding espresso machines many times in his videos, and brings it up often during reviews.
MKBHD is absolutely as qualified as 99% of his peers.
I would say his success is largely due to being among the first to the market in tech reviews and having (at the time) better production quality.
> The result is a freedom to use a far more thermally stable source of hot water - like the kettle you already have. And because no water is stored in the machine - it’s fresh every time.
Seems like a interesting idea, but I feel like there is a crucial point missing. What if I do not want a random water tube hanging into my water kettle? Feels like that is a big hole in a otherwise great thought through product.
I know they exist but I've only ever seen one house with such a tap and that was a very well off family member. I don't think these are terribly common.
It's a quite deliberate and slightly difficult action to activate the boiling water, there's a ring around the base of the spout that you have to double-press and twist on the second press, completely independent of the normal cold/hot water.
I have two young children and honestly, I'm not concerned either for them, my wife, nor myself that there's any risk.
Using the microwave is a perfectly good solution I think, but I don't know many people who do that, and although it's fine for tea etc for one person, it won't do a house-full of cups of tea in seconds, nor fill a pan with boiling water.
I wouldn't dare to suggest that it's the best thing for everyone, but we are extremely happy with its utility in our home.
EDIT: Typos
How's your experience been? Do you preheat your mug before brewing? I like tea strong and dark!
As for pre-heating, I tend to use it to pre-heat my wife's tea mug and my coffee cup before I brew with the espresso machine in the kitchen, by filling it part way for a few seconds and then pouring away; mostly to take the chill off, as our kitchen can be cold in the mornings.
I know there are lots of other cheaper brands but my understanding from researching several of them a few years back was that many/most of the cheaper ones won't keep up with the Quooker, won't be as reliable, and likely won't have the after sales support as a product from a company that specialised in that single product. There are the office ones you speak of but they're been weaker performing in my anecdotal experience of our office, and often come with service contracts.
I reckon hipsters will be drinking filter in a few years' time, if they aren't already.
As for hot water taps for tea, if you are brewing black/red tea that is usually not good enough as they don't produce truly boiling water, although some do claim to.
The 3L tank that holds the hot water, under the sink is well insulated and it takes almost nothing to keep it at temperature.
Given that it uses such negligible energy that I needn't care, the benefits of instant boiling water whenever we like and not having an extra appliance no the counter-top make it a clear winner for us.
My wife drinks tea (I'm a coffee drinker) and I make tea (just simple, English Breakfast with milk) for her quite often, and we both use it for cooking. It was something she'd always wanted, and she's not much into "gadgets" but she's been very happy with this, so I'm happy.
The only annoying thing about it is that the fill indicator is rather hidden by the handle, but otherwise we really like it.
I never understood why so many kettles always put the fill indicator behind the handle, which of course you'd be holding when filling it up. The first time I saw one with a large, clearly graduated window on the side (and wasn't also a cheap, white plastic kettle) I was impressed, being the nerd I am.
There's several around - I've got one that allows you to choose between 70°C, 80°C, 90°C and boiling (along with a keep-warm option that's never used). I use the 80°C option all the time for making coffee (Aeropress) and use the 70°C for things like green tea (black tea should be 100°C of course).
It's a mistake to use boiling water when making coffee - it'll extract a bitter flavour.
That's really cool, I suppose I haven't really looked, being a coffee drinker, a kettle was never important to me.
> It's a mistake to use boiling water when making coffee - it'll extract a bitter flavour.
I have two espresso machines, one in the kitchen and one in my home office, I also have an Aeropress like yourself, love it, but I only use that for travelling. Wouldn't dare pour boiling water over my freshly ground coffee :)
The biggest problem I've had so far was that Amazon seems to only stock used/counterfeit units. Buying direct from OXO got me on that hadn't been used and didn't reek of volatile organic compounds on the first try.
This is slighly terrifying; and interesting that something like this would be counterfeited. I too would make any and all efforts to ensure I was using something legit where mains (240V for me) are concerned.
I once bought a knock-off hot-air soldering station without knowing, and once I looked into it, people were complaining they'd received units where the live was "grounded" to the case.
I opened mine to check, not quite as bad, but the live in mine wasn't attached to the metal case, just bare, and within about 1cm of it. I reported it to the retailer (we all know which major online retailer this was), and they did nothing. Let's just say things changed, seriously, for me that day when it comes to buying anything mains powered with uncertain origins.
ThermoWorks refused to sell their products on Amazon for quite a while. Apparently they've changed their stance but I wouldn't risk it.
Anyways the kettle is nice to have that I use daily for coffee even though I now have an induction stove with burners that are far more powerful than the kettle. Stateside, circuits for electric ranges are 240V, 50A (occasionally 40A on older buildings).
> Even if I didn't despise Bezos
Hot drinks can be a bit of a ritual, as I'm sure you understand as an aeropress user, so I don't mind a bit of work to get the right brew if I need to do it, in fact one of the things I enjoy about taking my aeropress when I'm travelling whether camping or any other break, is having my coffee ritual with me.
This problem is solved in its entirety by simply microwaving a cup of water. No wasted water.
If the same / similar cup is used, one can choose the desired temperature of the resultant hot water simply by varying the time. Seasonal variation of ambient water temperature may need to be taken into account.
I tend not to drink coffee, and I prefer to make tea with less-than-boiling water.
YMMV
</opinion.
Now that I’ve written that, I’ll have to put a power meter on the microwave and a kettle and report back with the results. My kettle recently broke and I hadn’t intended to replace.
If a microwave was more efficient, I'd expect to see premium kettles that used microwaves instead of a simple heating element, though maybe there'd be design problems with preventing leaking microwaves.
For my use cases, I’m not looking to actually boil the water, bringing it up to 80 plus degrees suffices.
The inefficiency kettles bring is the tendency of certain users to heat way more water than their immediate needs.
220ml, regular ceramic mug, one minute forty, does what I need, but I’m not tea or coffee connoisseur, just a prole with a box of Twinings loose leaf.
Thanks for the kettle reference, I have been meaning to find a temperature controlled unit.
I recently picked up an inexpensive Thomson branded electric frypan with digital temperature and time controls, well impressed.
The energy usage is indeed minimal; I've measured it with a power meter over a couple of months and barely used a fraction of a kWh.
There are other boiling water taps, but Quooker is incredibly well built, really simple, and was created in an era of making things to last, it's got a price tag to match, but well worth it in our households opinion.
Those boiling water tanks would be very hard for a child to access without a lot of effort. Those boiling taps are sometimes close to the cold/warm water tap.
When a kitchen serves 100+ people things like limescale will inevitably be a problem. If the steaming hot water tap is plumbed in, with replaceable water filters and a regular service contract - that's an advantage, not a disadvantage.
Steaming hot water taps can supply lots of hot water fast, so even if a load of people are making drinks at the same time in between meetings, they can keep up.
There's also a safety argument that if you've got a kettle and a mug, that's two things of boiling water you could drop, and eliminating one of the two makes things safer. And because the steaming hot water tap is directly above a drain, the impact of a spill is much reduced. And a lot of these taps make water that is steaming but somewhat below boiling, which might be safer or something?
Not sure why you'd want one for home though.
Different teas require different and specific temperatures for optimal results. A hot water tap cannot do this. I love the minimalism in the product design for this!
The cheapest ones are about 10x the cheapest kettles. Can't imagine wanting to go back to a kettle personally.
I have never seen that anywhere at houses I visited in France, Germany, Italy, Poland, a few US.
I am not saying that this is not a thing, it is just that "so many" depends on the demographics.
Adding a boiler I'd guess would double the price, so I think it's a good decision to leave off.
If thermal stability is important enough to make such an advertising claim, you should probably show a comparison of input temperatures where the water meets the coffee over the course of multiple cycles against a representative competitor. With actual data rather than stylised cartoon graphs like in TV adverts for washing powder or whatever.
Woolly claims like that without clear evidence really make sound like audiophile woo territory, which would be a shame if you've actually done the research!
Traditional E61 espresso machines whose water boiler is at ΔT cm's away from the group head, solve the problem of temperature surf with heavy duty pipes, boilers, isolation and materials to keep the temperature loss at the minimum.
More modern espresso machines place the water boiler just above the group head so they're basically solving the problem other way around: keeping the ΔT at minimum so giving no or minimum space for temperature loss.
As for this design, I am not sure how does it solve this problem.
Also for $700 you don't want to be the guinea pig.
Without actually fully heating the coffee for your and having a tank, etc, I don’t see a huge advantage here over those types of machines.
A more comparable model from Flair would be either the Pro 3 ($325, all metal in the grouphead, pressure gauge, shot mirror... lots of included accessories) or the cheaper models they offer (Classic w/ pressure gauge, $230, Neo Flex, $99).
If you wanted to compare to the Cafelat Robot, that is also only $450... and is all metal, built like a tank, and has a very charming aesthetic.
In the category of "machines that don't froth milk", it might be the most expensive by $50.
In the category of "machines that have pressure control", it might be the cheapest by $700
In the category of "machines that have a rotary pump", it might be the cheapest by $2000.
It's sort of the curse of making something that doesn't clearly fit into a specific category.
51mm portafilters are better and some day the world will come to understand
Given the author has given us essentially nothing regarding what is actually controllable (besides pressure control?), it's unclear to me what you even can do with it. A simple pressure control is pretty basic and not at all comparable to the Meticulous or a DE1.
- Group preheat (so it has some kind of heater) - "Fully adjustable power" - ???
It does seem that the water tube either goes to a kettle and the pump is in the machine, or it goes to a pump, that you then need to attach to a machine, and that clear line is pressurized.
It does potentially have one feature the met doesn't (hinted at by allowing for filter brews): it'll be able to use up the entire water source, not a small amount of water you pour into the machine (similar to the Decent).
Edit: based on the manual just added, it seems like the pump is in the machine.
I'm really, really not seeing what could possibly justify this price. If the 'control' is just as simple as an analog knob, then this is no different than adding 'flow control' via a common dimmer switch to any other pump. I've done this modification on vibratory pump models myself, and they function just fine when dimer switch modded.
The pump absolutely is a "big deal" though if they can deliver on it. It has been attempted (Decent is trying to make one - actually they have been trying for years) and no one has delivered on a pump like that to date.
* No heating control
* No tank/water storage
* No milk frothing capability
The obvious comparison is a manual (lever) espresso machine that does not offer its own heating capability. It offers pressure control (via your arm) just fine.
Also, besides noise complaints and possibly some questionable reasoning involving vibe pump longevity, I have yet to see a compelling reason a rotary pump is better. They're 'nicer' and offered in higher end stuff, but performance wise a very good vibe pump seems just fine. Flow rates are more than adequate for pretty much any normal brewing method.
Regarding 51mm vs 58mm: you might be correct technically, but the ecosystem around accessories is firmly in the 58mm camp. As far as I can tell, the difference is so marginal it doesn't really matter anyways. Puck prep and other things will matter more for the average user.
Also you can totally work while the pot is getting to temperature.
I preheat the moka with hot water and fill it with hot water from jug to reduce time to brew (necessary due to stove setup).
Also, for $700 independent reviews are also a must.
For the pump kit - this too looks interesting, but requires (way) more details. At the very least a list of supported machines and, again, a video or two of an actual retrofit. Dimensions, voltage (!), etc.
